Tesla Model S End-Of-Range-Anxiety Announcement, P85D Top Speed Increase and Valet Mode


Elon Musk Tweets Ahead Of Today's Conference Call

Elon Musk Tweets Ahead Of Today’s Conference Call

Software 6.2

Software 6.2

Foreshadowed by a Tweet from Elon Musk earlier this week, the news coming from Tesla Motors regarding its plan to end range anxiety for the entire Model S fleet is as follows (via Elon Musk on conference call):

  • Software version 6.2 will address perception of range anxiety
  • Range assurance is always on.  It will warn you if you are driving beyond the range of a charging station.  Takes into account weather, elevation changes, etc.
  • To drive beyond your cars range, you will have to basically override the system by acknowledging the fact that you’re okay with driving beyond its range.  Car will notify you and you’ll have to acknowledge that your intentionally going against the cars suggestion.
  • Trip planner tells you how much you’ll need to charge to arrive at next destination/charging station

Also included in the ‘over the air’ update is the return of valet mode.

Valet Mode conveniently and discreetly limits Model S’s driving performance and restricts access to certain settings and personal information. With the touch of a button, owners can place a limit on speed, lock the glove box and frunk, and disable personal information like driver profiles and homelink settings.

The update also automatically increases the P85D’s electronically limited top speed to 155 mph.

Some additional details via The Street’s live blog of the conference call:

The first of the two application is range assurance application. This , in real time, communicates with Superchargers and destination chargers and it warns you before you drive out of range.

Over next 12 months, all over Europe, North America, Japan main islands and good chunks of Asia will be covered.

Also factors in wind speeds, high mountain ranges. Don’t need to do any thinking ahead of time.

“It’s basically impossible to run out of range, unless you do so intentionally.”

Supercharger network and time driven/time ratio works out really well.

Also tells you how long it might take. Typical journey starts around 9 a.m., drive for 3 hours, get bite to eat. We’ve placed Superchargers at standard inflection points.

The second feature is trip planner. It will now look up supercharger in real time to get you to the most convenient route to your destination. You can get messages from Tesla phone app.

Full press release on the update is now available from Tesla Motors – below:

Model S Software Update 6.2

Model S is the only car on the road that improves with time, thanks to Tesla’s free, over-the-air software updates. With each new update, Tesla adds functionality, enhanced performance, and improved user experience to every Model S.

Today’s announcement of software update 6.2 introduces new features that expand the car’s intelligence which eliminate range anxiety entirely, enhance Model S’s active safety features, and bring Model S closer to having autonomous capabilities.

Energy and Range

Our energy and range functions eliminate “range anxiety” and remove the hassle of planning road trips before you embark. By introducing Range Assurance and Trip Planner into Model S’s navigation, long distance travel is now foolproof.

Navigation automatically routes Model S through Tesla’s charging network. Currently 90% of the US population is within 175 miles of a Tesla Supercharger; finding quick and convenient charging has never been easier. Include Tesla Destination Chargers and 95% of the US Population is now within ample range of Tesla’s charging network.

Trip Planner

Model S owners can now take road trips with confidence. Simply select a destination, and Navigation will now automatically route through the appropriate superchargers if charging is needed for your trip. Trip Planner will select a route to minimize driving and charging time. At each supercharger stop, Trip Planner will notify you via the iPhone app when you’ve charged enough to continue on your trip. Android app users can monitor charging needed for the trip via the Charging screen.

Automatic routing along Tesla’s Charging Network

Drivers can choose a final destination and Model S will route them through charging locations automatically. Navigation will display the fastest route to the destination and break the route into legs between Superchargers, displaying anticipated charge times at each station in a simplified list view.

Push Notifications at Superchargers

Model S will notify drivers via the App when they have enough juice to depart for the next Supercharger or their final destination.

Range Assurance

Model S does the thinking for you. By continually monitoring and advising owners when they are at risk of driving beyond the range of reliable charging locations, “range anxiety” is gone. When the warning is triggered, Model S provides a list of Superchargers, Tesla Destination Chargers, and locations where the vehicle has previously charged that are within current range. Drivers then select a charging destination from the list and Navigation will provide turn-by-turn guidance along with the predicted battery energy when you get there.

Driver Assistance Features

The new Driver Assistance features in 6.2 are designed to intelligently anticipate and react to potentially dangerous situations. Since the unveiling of autopilot in fall 2014, Tesla has pushed a number of active safety features to Model S via wireless software updates that enhance the safety of Model S and bring Tesla closer to rolling out full autopilot capabilities to vehicles on the road.

Automatic Emergency Braking

This new Collision Avoidance Assist feature automatically engages the brakes to reduce the impact of an unavoidable frontal collision. Automatic Emergency Braking will stop applying the brakes when the driver presses the accelerator pedal, the brake pedal, or sharply turns the steering wheel.

Blind Spot Warning

Blind Spot Warning assists the driver to change lanes safely. When Model S is travelling between 20 mph (30 km/h) and 85 mph (140 km/h) and detects a vehicle in the driver’s blind spot, a white arc will appear on the instrument panel near the bottom of the speedometer. If a collision with the vehicle becomes likely, two red arcs will appear, the steering wheel will vibrate, and the driver will hear a chime.

Valet Mode

Valet Mode conveniently and discreetly limits Model S’s driving performance and restricts access to certain settings and personal information. With the touch of a button, owners can place a limit on speed, lock the glove box and frunk, and disable personal information like driver profiles and homelink settings.

P85D Top Speed

The top speed for P85D is now 155 mph (250 km/h).

Recently Released Software Update Highlights:

September 2014 (6.0):

Traffic-based navigation: The model S navigation system now takes real-time traffic conditions into account when determining your route, and estimated travel times are adjusted to reflect traffic. This feature will also continuously monitor traffic while navigating, and re-route if warranted.

Location-based smart air suspension: Useful on roads or driveways that require higher clearance, with this feature, Model S will remember where you select HIGH or VERY HIGH ride heights. The air suspension will then automatically rise at those locations in the future.

Calendar app: Allows drivers to view their phone’s calendar for the current and next day. If a calendar event has a location specified, they will be given the option to navigate to that location. When they have an event on their Calendar that will take place within the next hour, the Model S navigation system will notify them if there is a better route due to traffic, even if they’re not using navigation.

January 2015 (6.1):

Traffic-Aware Cruise Control: When TACC is engaged, Model S will adjust its speed based on the car directly in front of you, decelerating and accelerating as needed.

Forward Collision Warning: Forward Collision Warning will warn you when there is an object in your path and a collision is likely unless the driver takes corrective action.

Auto High Beam: Auto High Beam temporarily switches Model S to low-beam headlights if there is traffic or urban lighting detected in front of the car, such as from an oncoming vehicle or street lights.

The beginning of intelligent EV route assistance comes from Tesla of course.

Can’t wait to hear how See Through and other haters try to negatively spin this.

So what sort of positive spin are you stating here? That’s it’s good for Tesla to decide whether you can go to a certain place or not if range is in question? And in condition when there are multiple routes available, e.g. hilly but shorter versus level but very long routes, who should decide which route to take? You, or the computer? Mind you, it doesn’t say in this article what’ll happen if you press that “I acknowledge” button. Will it mean that, previous support from such situation will now be removed from offering? This doesn’t seem like a sounded business decision (regarding the range part) and may really show the lack of auto business experience – an automobile represents freedom, not limits. Similar offerings have been in the LEAF since 2011, though not as sophisticated (hill ascends/descends and weather aren’t included in the algorithm). Those other safety features are either standard or optional in most mid to full luxury vehicles in most makes already. It’s good that Tesla’s finally offering them, but should really be there in day 1 (due to its price). To me, this is not about ending (or addressing) ranger anxiety. It’s just a gimmick to… Read more »

Um, your still free to drive your Tesla anywhere you want. You simply have to acknowledge that you may exceed its range and have to charge again.

Kind of like when your car navigation makes you hit the ok button (for the disclaimer) before you can use it.

Should also note that this enhancement feature is completely optional to use by the driver.
In your daily driving you rarely need navigation anyways so you would really only use this feature at your decision to use navigation.
Also, this only comes into play on low battery so as long as you are charged up as you are likely to be on daily driving it doesn’t affect you.

In other words, its only there when YOU need it.

Which is why I’m asking [you] – what sort of positive spin here in really ending/addressing range anxiety?

By “limiting” – or should I say, “notifying you” – that you can’t drive to a certain location due to range (for whatever reason), which, you would probably know before this announcement?

So the solution is to press a button saying, “yeah, I know.”

Well with that logic, I guess we can throw away a lot of technology that makes our lives easier?

Don’t put words in my mouth.

My logic is very simple – label something to be what something really is. Period.

This is an improved and much more accurate navi system. It has nothing to do with addressing/ending range anxiety.

RA is when we WANTED to go a certain distance (1 trip or multi trips), but we aren’t exactly sure if we can make it, and chances are, probably won’t. But we do HOPE, because we WANTED to make it.

The real question (of RA) is – how do we make that “wanted” into “can?”

A button that says “you can’t” – doesn’t address or end anything, because the desire to do it is always there!

Range Anxiety exists when people start fearing they won’t be able to get to the next charger/destination before running out of battery. The whole idea of the software update is you don’t ever have to worry about ending up in such a situation, as the computer will let you know how to avoid it happening in the first place.

Nobody got range anxiety from being told they won’t be able to drive far enough and then making a conscious decision to alter the course of their route. People got range anxiety for the exact opposite; finding out at the last minute that they will barely – if at all – reach their destination on the current charge.

We have system that tell us where we will run out of juice.

This is what range anxiety is about.

Will it be enough to drive me from A to B?

With Tesla S answer is:

Will manage, if not, will tell You beforehand.

That end range anxiety.

You know Yes/No, before hand.

Ofc. Your point about choosing route is….


Who will choose route that is dead end? And will blame Navi for suggesting that its not the way?

Because that is what You suggest.

You want to get to B, but have no juice to go there by that particular route.

You get warning. You do not want it. You want to drive anyway.
(Just like Navi would tell You “dead end, wont get You to B!”)

Its not car defect. Its human defect…

When Your **ICE** car tells You that You run out of fuel, You ignore it too? Or reluctantly head to nearest gas station???

Because fuel indicator is just DUMB and UNRELIABLE version of “Range Assurance”.
Cause You have much higher uncertainty then 1%… (Try it on mountains with bad weather!)

For long trips, their Nav will automatically guide you along a viable course that includes charging and is free of range anxiety. Or you can pick your own route as you could before.

That’s better than it was. Customers will want this. No “spin” is really needed.

Tesla is doing calculations for drivers that have always involved simple math, but lots of it. It was a bit of a headache to convert ‘Rated Range’ into what your actual range will be. So, drivers who didn’t want to fuss with the calculations, who consequently do not test the Model S’s superior range, are now more encouraged to exploit what was always their.

The volt “forces” you to click through a low-fuel warning, and I imagine lots of cars already do this aspect (as a favor). So, nice try.

The positive is in their making the car more, and more, intelligent

London Bell, wow, you figured out how to put a negative spin on this. Not that you make any sense.
The technology is awesome. No need for a calculator and manually figure out which route to take.
Although you are not satisfied. I learned in life that it is not worth trying to satisfy negative people. They will never be satisfied.

Yeah, well he’s just naive. Every EV driver knows to manage range; I fail to see how software that does that management for you could POSSIBLY be a bad thing.

Maybe ignorance is bliss and he mistakenly assumes the majority of EV drivers would rather not know if they have enough range left–would rather wing it and hope for the best?

Sheesh. Some folk will complain about anything. “Oh no, my car’s scaring me by telling me I’ll run out of range if I take the route I wanted to take!” or “How dare my car have the temerity to suggest an alternate route that will guarantee I reach my destination, rather than take a gamble!”

Pretty sure Londo Bell is a used car salesman at a GM store, trying to unload Volts

Still nothing about recharge time.

Emergency braking…great feature! I also like the comment about 200 mile range not really passing people want 20-30% more. Maybe the Model 3 will have more than 200 mile real world range.

It doesn’t matter what range a BEV has, some people will always want more. Even in the future when charge times get down to 5-10 minutes, superfast charge stations can be found almost anywhere, and BEVs commonly have a range of 350 miles before needing a recharge… even then, some people won’t be satisfied.

No matter what you do, you can’t please everyone.

What a pessimistic you are, 🙂
The range will be 500 miles, and recharging will take 30 seconds!

Let’s hold out for beamed power, provided free 24/7 worldwide. That really -would- end range anxiety! 🙂

Charging times will not got down to 5-10 minutes. Such amount of electricity does simply not fit through a useable thick copper cable. And no, there will not be a sudden better solution than copper cables in the next 20 years.

Use multiple strands – already Tesla L2 cable (and some others) do that.

Super capacitors do charge in a matter of seconds!

CounterStrike Cat said: “Charging times will not got down to 5-10 minutes. Such amount of electricity does simply not fit through a useable thick copper cable. And no, there will not be a sudden better solution than copper cables in the next 20 years.” It was the CTO (Chief Technology Officer) of Tesla who was quoted as saying Tesla wants to get down to a 5 to 10 minute recharge time. But if you think you know more than he does about the subject, you go right ahead and argue with him. 😉 My personal opinion is that we’ll get down to about a 10 minute recharge time, and then the economic pressure for faster charges will peter out in the face of exponentially increasing costs, so I question we’ll see 5 minute recharge times for a nearly empty battery pack. Re the actual hardware: On another forum, we discussed this concept in detail with an engineer familiar with high-voltage electrical engineering. According to our calculations, you need a cross-section of slightly less than 1 square inch of copper to carry that much current. Certainly that’s a lot more robust than current charging cables, but it’s not much of an… Read more »

Clarification: You need a connector of slightly less than 1 square inch cross section to have sufficient mass to prevent significant heating while carrying that much current. A somewhat smaller cable could carry the current, but resistive heating would limit it to short charge times.

As I recall, we were using the premise of a 100 kWh charge in that 10 minute period. Obviously you can pick different assumptions and get different numbers, but our back-of-the-envelope calculations showed us that it’s entirely practical.

200 miles because the smaller battery is 60Kw/h that is why Super Charger locations are 175 miles away from each other.

I can hear it now: “What? No pulse mode that doubles the EPA range of every model S to over 400 miles? No Tesla Coils around the country to wirelessly beam power to your Model S?”

I’m not going to lie, I’m disappointed by the lack of Tesla coils in this announcement.

I was hoping for flying battery swap drones. 😉

My 2007 Chevy will map the nearest gas station. This is ancient technology. Should already have been standard.

I think the Model S could always guide you to the nearest charger. What this is doing is monitoring when you’ll require a charge and then allowing you to choose a station.

It would be like your 2007 Chevy knowing that you’re going to run out of gas on a long stretch of desolate interstate because there are no gas stations for the next 50 miles and you have 2 gallons in the tank.

My Chevy doesn’t have to know if it is a long desolate interstate. I know. Is EV mileage that volatile?

Range is definitely more volatile than a gas car in regards to the conditions listed. Plus in a gas car, you’re probably never further than 50 miles from a gas station (and you’d really have to hunt to find such places), but most of the time there’s probably over 10 gas stations within a 10 mile radius of you. Its the combination of these two things that necessitates a monitoring system like this.

Gas vehicle range is even more adversely affected by temperature, etc. EV range is highlighted because there is such a small amount to work with (excluding Model S).

The Model S also can charge from L2 or even 120V outlets, though it’s painfully slow. This software update highlights where Superchargers are and if your route will take you too far away from one. You can always charge from those other sources in an emergency.

Rule of thumb seems to be that very cold temperatures can reduce an EV’s electric range by about 20%, and if you run the cabin heater, even moreso. Much as I’d love to see gas guzzlers disappear, I don’t think it’s realistic to claim that they’re affected by cold weather as much as PEVs are.

We can hope future improvements in EV batteries will include better tolerance for cold, but that doesn’t seem to be anything that will happen within the next few years.

For the third time, at 0°f, an ICE car loose ~20% of efficiency, and a Leaf-like EV ~30% , BUT 65% of the loss in an EV is from heating the cabin… and this loss is a CONSTANT factor that will gradually disappear as the battery capacities grow. In a Tesla the loss is less than in other EVs

So ICE car will always loose ~20% and EVs soon will have less loss than ICE cars in winter. 🙂

This is a study from thousands of commercials fleet cars.


I think the study you’re citing is using cherry-picked figures to promote a “Green” political agenda.

Here’s one that seems more realistic to me:


About 12% loss for the gas guzzler in 20 degree conditions, and nearly three times the loss for EVs. Admittedly the loss at 0 Fahrenheit would be greater, but even here in Kansas, it rarely stays that cold for long.

Of course that’s only one study, and I won’t claim it’s definitive. But a 20% loss of MPG, even in the coldest weather, simply doesn’t match my decades of experience driving gas guzzlers.

I’d be careful about quoting studies from the media. Yes, the study was from Oak Ridge, however, the media is pretty good at cherry picking results to form a certain narrative rather than conveying actual facts irrespective of the conclusions. Just look at the climate change “debate.” Climate change is as close to a foregone conclusion as scientists can get yet the media frequently spins it (regardless of alleged political bias) as a continuing debate.

Agreed, I would add that fleetcarma had data collector modules in thousands of commercial cars, data as exaustives as drivers habits… But lensman has aslo an habit of EV bumping, in many of his comments.

The problem is not efficiency reduction in isolation. Together with the fact that recharging is slow and the recharging is slow and the network sparse is what makes the efficiency reduction a big problem.

I can’t make it do destinations like airport or suburban malls in winter – something I can do with ease in summer.

This is where the longer range helps, ofcourse.

“So ICE car will always loose ~20% and EVs soon will have less loss than ICE cars in winter. ”

That fleet carma study is clearly showing the colder temperature increase the EV loss by signficant amount where the ICE is fairly constant vs. temperature.

% also doesn’t reflect the fact that recharging is still far harder and slower than refilling.

Zero farenheit is a pretty good average of cold temperatures unless you live in Kuujuaq
And talking percentages, remember that ~95% of recharging is done at home, as easy and fast than pluging your phone at night.

And revising the graph and data, the difference of efficiency of the EV is DECREASING with temperature below 20°F. The ICE curve part is much reflecting a constant loss.

A Model S doesn’t need to know there’s a long desolate highway any more than your Chevy does. You need to know it in both cases. Unless you would think it would be bad for your Chevy to start telling you, I don’t see your point. If you think it would be bad, I still don’t see your point. Model S owners could look at their battery life all along. They could find superchargers on the map all along and the car already predicted whether they had enough electricity to get there if they navigated to one. This isn’t really about helping most Model S owners, but about critics who make senseless arguments. Some people seem to have nothing better to do than spend their life commenting on Tesla and saying they don’t plan to own one. I don’t plan to own Jeep, but it doesn’t mean I waste my life going to Jeep forums to complain about it. So that means there’s a lot of misinformation out there. What Tesla cares about is that when a potential customer goes into the showroom and asks about what might happen if the battery runs out, they can explain to that person… Read more »

Mapping the nearest charging stations has always been a standard feature of the Model S and even the LEAF.

This goes well beyond that, looking at temperature, road slope, rain/snow, and wind to calculate how far you can travel.

This is indeed a much more accurate range calculation than any other guess-o-meter implementation so far. My Leaf’s GOM is often more likely to *induce* range anxiety than it is to eliminate it. One trip I’ve done several times, typically what happens is that the car uses the *average* energy consumption since the last stats reset to determine how far I can go, and comes up rather much shorter than reality when I’m going to be losing 600 m altitude on the way home.

I still use the GOM as a rough guess, but I only use it as a rough guess. Including terrain and weather like the new MS update is a huge improvement.

Best NAV enhancement I’ve seen in forever.

Love that, Location-based smart air suspension feature.

I’d like to know more details about that. Like when does the suspension return to normal height.


It is pretty cool. Been in the releases for a while. When you set the suspension height it automatically stores where and at what height it was done. I think you have to be under a certain speed and it may be after the second manual setting at the “same” location the triggers it, not sure about these details. Once you are in a certain proximity (~150-200′) of a stored location and under the speed restriction for the stored height, it will change the suspension height. If you moving too fast it will beep subtly as a warning is displayed that the height can’t be changed due to speed. It is a great feature to avoid high parking stops, steep dips/bumps, and allow for easier entry/exit at stored locations for those that prefer to enter/exit at the highest setting.

I personally do see how it ends range anxiety. That is pretty bold to say that statement. When I travel long in my MS, I have always known where to charge and overestimated to be safe. But I have rolled into a charging location at 0 miles, due to weather. This is a really nice feature, to do all the calculations, but I will still feel anxiety, trying not to overuse the energy when i’m on a longer trip. I fell like i’m frugal, with my engery; “dont turn the heat up, dont roll the window down, slow down, coast”

I’m not trying to be negative, I can’t wait til my next road trip, but I can’t say my anxiety is gone.

It doesn’t really solve range anxiety as much as do a better job at verifying range. Unfortunately it might actually waste time, because you’ll be depending upon the car rather than thinking for yourself. Instead of running the numbers and deciding, “I’m not sure we’ll make it, better take the Honda” before you leave the house, you’ll be hopping in the car and after a few miles realizing “The car says we won’t make it, better turn back and get the Honda.”

But the car isn’t likely to do that in real life. It’s not like with an ICE car where you go day after day and eventually decide that your needle is too low and go to a gas station. In that case, you might have to wonder if you can get to your destination of if you have to fill up first. With a Model S, owners will typically start off with a complete charge each day. They could forget to charge, in which case they would charge the next day. Even skipping two, three or even four days isn’t likely to cause trouble based on the number of miles that the average driver goes per day. So they aren’t likely to say “Better take the Honda.” They are more likely to never need to charge outside of the home except in cases where with an ICE car they would start with a full tank and need to refill the same day. Assuming they start out fully charged, they should be able to make it anywhere they would go on a typical day with no problem. If they will be traveling hundreds of miles, the car will tell them where… Read more »

Trying to understand how this would work. Looking at the map, there’s a SC in southeast Tenn, one in northern Tenn, and then nothing for a while heading northwest.

So I’m a fool… I get a charge at the SE Tenn charger and head northwest (no navigation). At what point does the car tell me I should hit that north Tenn SC? Once I’m 30+ miles past it? Not saying that’s not a valid time, just trying to understand how smart/predictive it is.

I suspect this new feature is dependent on you using their Nav. Then their Nav will automatically route you to the most appropriate charger that in route.

If you don’t use their Nav, then you are on your own as before.

No. You don’t need to use the navigator for this to work.

Maybe this was announced before and I missed it but Elon said more Superchargers will be installed worldwide in 2015 than in all previous years combined. So more than doubling worldwide Superchargers in 2015.

That’s huge to me.

I’m not one who thinks Tesla can do no wrong but they’ve certainly got charging figured out IMO.

I agree. It’s very forward thinking in anticipation of all the Model S,X and 3’s that will be on the road in the not so distant future.

sure, some navs have had one or two of these features, but this is the first time it has been a coordinated planner with all the charging needed. It estimates charge time and gives your arrival time based including charge time which is a real first.

My range anxiety went away when I dumped my LEAF for a Model S

+1, good one…

Thats funny, my range anxiety stayed the same when I dumped my Model S for a LEAF! (The same being basically non existent).

Yay for smart “Nagware”.

Yay for not so smart trolls.

Batmobile: “Master Bruce, you did not use the last Bat-Charger when leaving Gotham City. Do you acknowledge that you will be unable to make it to your appointment with Selena?”

Batman: *Increases speed* “Just keep driving…”

Batmobile: “If you continue to ignore my recommendations and waste additional energy while driving, I will be forced to initiate ‘Valet Mode’, sir…”

Batman: *Drives even faster* “You wouldn’t dare…”

Batmobile immediately slows as red text is displayed over the digital speedometer: “Valet Mode Active”.

“Holy BatSh**, Robin, Why did I get the Batmobile with the Small battery?”

Does this system require you to put in a destination? Or can you just jump in your car and start driving?

By what I’ve read, you can do it either way. If you don’t enter a destination, it monitors where you are and if you are going out of the range of chargers, it will pop up with a warning.

Anyone who has range anxiety in a Tesla can only blame themselves, not infrastructure or technology. They shouldn’t be allowed to own one if they can’t figure out that they are too far from a charging station.

Pretty much what I expected. But I think many are going to be disappointed because they thought that somehow they would increase range.

And they will eventually when they release a new, higher KWH battery pack for the existing Models S’s.

I bet you 1 peso it will be along with the introduction of Model X.

The ability to “drive beyond your car’s range” has been a great feature in my Tesla Roadster… In the Roadster you always have the option to access the bottom 10% of your battery which is not used while driving on a standard charge. The Model S (85KWh) has always had two battery buffers in place that were inacessible and not included in the stated range; 5.1 KWh is reserved for “Zero Mile” Protection, and 3.9 KWh is reserved for “Bricking” Protection. It sounds like Tesla is now going to allow people to override these buffers in order to make it to a destination if they are likely to fall a little short in their normal planning due to unforeseen circumstances. Having access to this extra 10 KWh battery could extend your range by 35 miles or more depending on your driving habits. Naturally, it is not ideal to use this buffer repeatedly as it is there to protect the battery, but this is the same case in the Roadster. I have personally used this buffer in my Roadster a handful of times in the past couple of years even though I plan otherwise. It REALLY DOES eliminate my range anxiety… Read more »

At least this is how I interpret “driving past the car’s range”… perhaps he just means “driving past what the navigation system says is possible” and has nothing to do with battery access at all??

No range anxiety in my 70 mile range Smart ED

Cant imagine there being “rang anxiety” in a 200+ mile range car

The (r)evolution continues. This is welcome news although I’m hoping that non Tesla chargers will be included in this smart trip planning in a not-so-future update. With priority given to the supercharger network, when available, incorporating other charging venues (not already visited, which the car already knows) can be very helpful.
And how about being able to weigh the options between driving 30 min out of your way for a 10 min supercharge vs a 5 min detour for a 20 min L2 charge?
Since it is communicating with the SC network, hopefully it will also be able to show how many charging stalls are currently available and how many other Teslas are en route to it.
The potentials, and the determined pace to exploit them, is exciting. It can only keep getting better.

Yeah. Giving the Model S driver real-time data on how many stalls are available at the SuperCharger he/she plans to use, and offering an alternative charging location if they’re all in use, seems like a natural upgrade. I’m surprised Tesla still hasn’t added that feature.

Reminds me of Siri. It’s cool but more of an answer in search of a problem than anything.

I don’t think EV owners have range anxiety. You know how far the car will go based on how you drive it. What you do have is limited range and slow charging. This “fix” doesn’t help with either of these actual problems.

For example, if I’m driving around town then even 150 miles of range is overkill. If I want to go to LA then it’s not enough to get there and back. I’d have to charge somewhere along the route. The question then becomes whether I want to take on the hassle of doing that or just take a different vehicle.

Or here is a slightly different scenario. If I want to go to June Lakes there are enough chargers to get there. However, once there it gets dicey. There are a couple of chargers at hotels in Mammoth but those are private and Mammoth is a drive. Using 120v charging wouldn’t really work. So again the problem is limited range and slow charging, and the answer is to take a different vehicle.

Don’t see how a route finder/helper changes the calculus.

You’re wrong on both counts.


Telling Siri “directions to the nearest McDonalds” solves the problem of trying to find the nearest McDonalds with Google, then getting that address into the Nav app, and all while driving. Plus such acts are now illegal in my state.

Tesla Nav:

For long trips, their Nav will automatically guide you along a viable course that includes charging and is free of range anxiety. No pre-planning required. That’s better than it was. Customers will want this.

Nothing against you … I’m seeing similar negative nonsense being posted on every blog in site. Even if Musk had announced flying Tesla unicorns that recharge their cars in-route, people would still be bitching…

“Tesla unicorns make CO2 and only come in beige!”

Ha! Impossible! Flying unicorns come only in fluo-blue and barbie-pink! liar!

Over 80% of iPhone users don’t bother with Siri. Probably a higher percentage of Model S owners won’t bother with this. In both cases it’s just extra stuff with no real value added. But hey, if you want to delude yourself, go for it.

If you frequent the Tesla forums, this is something a lot of Tesla owners (and other EV owners) have been calling for a long time. Before this, either you have to leave a huge range buffer (not always viable) or you have to use a tool like EV trip planner to meticulously map out your route and figure out all the weather inputs (there are long threads on how to do this). Given there is a computer in the car, it always made sense to have the computer do that work, but no automaker put in the effort to work on something like this.

The previous solutions in pretty much all EVs are based on driving history and just don’t work well in hilly terrain or bad weather. Something that works based on looking at the terrain/weather of the rest of the route is necessary.

Also the station suggestion has real time availability information too (knows if a station is occupied).

You’re probably wasting your time trying to educate DonC. He believes what he believes and has little regard for new facts.

For example, I could point out the fact that voice-control systems like Siri are now part of almost every new vehicle and cell phone. But that wouldn’t matter to him, since voice-control is still useless and I’m still delusional.

There’s a lot here that’s a significant improvement, in the range calculator, the trip planner, and more! So, that’s great for Tesla and great news for Tesla Model S owners, and I don’t at all wish to minimize that. I wish that could be the end of this post. Unfortunately… Tesla and/or Musk decided to wildly overstate the case by doubling down on the clearly false claim of “ending” range anxiety, by claiming “It’s basically impossible to run out of range, unless you do so intentionally.” Not only isn’t it impossible, I confidently predict someone will demonstrate it is possible by doing just that, and probably in less than a week after this update goes into effect. What is “basically impossible” is for any range calculator to take into account every possible factor affecting range. The calculator can only take into account the data fed to it. As they say in computer programming: “Garbage in, garbage out” (aka GIGO). Tesla’s onboard computer can’t magically predict weather forecasts which turn out to be wrong, or road conditions and detours not reported online. Nor can any computer possibly precisely predict just how fast a driver will drive at every moment, or whether… Read more »

Don’t forget ICE cars have range anxiety too.

My personal example: Driving back to Texas from Florida, I was going through Alabama and, because it was a holiday, most of the gas stations along the route were closed. (This was quite a number of years ago.) I didn’t figure it would be a problem to refuel, but it was.

When I finally got to a gas station, I ended up putting 14.75 gallons into my 15 gallon tank.

I’ve been there too, but more because I’m absent-minded and sometimes forget to fill up when I should.

IMHO Tesla would have done better to say “We can’t completely end range anxiety in all cases, any more than a gas-powered car can completely eliminate the possibility you’ll run out of gas. But the following improvements will make range anxiety a rare thing…”

Gas stations closed? Does it exist gas stations where you can’t get gas 24/7?

Most US stations don’t allow credit/debit card use after business hours like so many in Europe. Someone has to man the station to stay open 24 hours to sell you fuel during overnight hours.

In some rural areas in the US, there just isn’t enough business to support being open 24 hours. There are many areas where you can easily run out of fuel if traveling at night.

Interstate highways and most other major routes are well covered by 24 hour stations.

In every one of the 20 US states, 2 Canadian provinces and 17 other countries I’ve driven or ridden a motorcycle in.

Completely human-less stations are pretty rare IME. There’s usually at least one person supervising the station (I think that’s partially for safety reasons — petroleum products are kinda flammable and environmetally nasty if spilled), or selling in the attached convenience store.

Also, on I-10 in Western Louisiana there are 50+ miles of elevated road over swamp with no gas stations in sight. Need to pay attention on those stretches no matter what powers your vehicle.

ICE Range Anxiety can happen even if driving at night but before midnight – like – on Farm Road 170 in Texas between Presidio and Terlingua! We were on fumes before Lajitas Golf Resort & Spa – still some 12 miles before we get to Terlingua, TX!

This is just a short 51.5 miles distance, and Google Maps says 1 hour 30 minutes! Driving is almost never in high gear, and with every twist, dip, hill, and gully, you drive through, you are mostly in 2nd gear of a 4 speed Automatic, and Fuel Range for a freeway trip means nothing! We used 3/4 of a tank for this short – short drive! Had to bum/ buy Gas at this resort – from their Storage Tanks for the Golf Carts! Interesting – at about 10:30 – 11 PM, too! http://goo.gl/maps/J0nNr

Yeah, I find a lot of the non range anxiety aspects more interesting. Glad to hear they added an emergency braking feature.

Tesla’s OS is definitely becoming a competitive advantage for them. They now have years of experience of identifying problems, creating software update based solutions, and deploying those solutions OTA.

If I had a choice between two completely equal 200 mile range EVs but one is a GM and the other is a Tesla that costs a few thousand more . . . I’d go with the Tesla because you’ll get better continued support and access to the superchargers.


If I were Musk, I would be tempted to play a little bit on all the bloating his tweets produce in the media.
He has created the “Musk announcement’s” waiting time anxiety. 😉

Seriously, he certainly exaggerated with this one.

Great. I just got the update and tried it out. When I tried to go faster and further than I should to get to another charger the car stepped in.

I was a bit scared though at first when I could no longer control the car myself and I heard a voice in the speakers saying “I’m sorry Dave, I’m afraid I can’t do that”.
And my name isn’t even Dave!



Yes… It might also attempt to kill you because you are jeopardizing the mission by wasting energy on climate control…

Drivers of a high functioning Model S need to worry when it looks at you through a red lit dash mounted camera.

‘Hal – open the Pod Bay Door (Frunk’)’
‘Sorry Dave, I can’t do that now, not while there is a man struggling to get out there, you might run over him!’

And I bought a new pair of socks today, could someone here let me now how I could hype up this event and have it discussed in the media ?

“PVH has ended cold feet anxiety! It’s now basically impossible for him to get cold feet unless he does so intentionally.” 🙂

First become the founder of 3 successful companies and become a billionaire. After that, it is pretty easy.

Elon was not a founder of Tesla.

OK, so don’t count Tesla. There’s still SpaceX, paypal, and Zip2.

Zip2 was only like $300 million, so I guess you need to figure out if he qualifies as a founder of Solar City.

Opps, misread your original statement. I read 3 billion dollar companies, sorry tired tonight.

Stock down 3% . . . I’m not surprised. That tweet set up expectations that could not be met with just an OTA update. For me, the update is better than I thought it would be . . . some nice new stuff.

Biggest and most important update in my opinion is the automatic emergency braking. It’s one important step further on catching up on active safety.

It does not help that several media / news sources purposely reframed statements to create higher, false expectations. For example: CNN’s headlines turned Elon’s tweet into some promise of extended range.

Day Traders were struck with the disappointment of reality, and of course– the stock dipped.

Because Sheeple. 😉

LOL, some outlets were setting expectations by referencing the OTA update Tesla did last year to extend the range of the Roadster to 400 miles… good lord the media is absurd

Indeed. People don’t understand much about science & engineering. They expected magic from a software update. It doesn’t work like that.

Media Needs a Musk Translator.

Musk Code V1.001.0

‘Tweet’ – a tease of something I’ll Tell you about later – but wait – it’s going to rock your world!

‘Update’ – and update or summary of an event we (Tesla Motors) actually did, a project test, or an in depth explanation of Tesla Facts, generally – a Blog Post.

‘Investors Call’ – an event that all can listen to, with facts, present live, but hedged in Stock Market Limited terms, and in a controlled voice.

‘OTA Update’ Not the same as a tweet, and not the same as a Hardware update (IE. – Dual Motors are not OTA Updates), can not do Magic, beyond reason, but can refine existing conditions, and make often requested extensions in Software on Tesla Vehicles with OTA Update Capability!

‘Hardware Updates’ – Actual Service Center visits required, with Scheduling, to change, add, or swap hardware on your Tesla. May improve Safety, Aerodynamics, or Range, depending on particular update: See Pending updates on Tesla Roadster – going from a 53 kWh Battery to a 70 kWh Battery, & other parts added!

Musk Code V1.001.1 code fix will be released a a later date! (By Me!)

Part of the point of the announcement is recognition of Supercharger growth. Gas stations solved range anxiety for cars. Tesla is on the cusp of solving it for (only) its EVs. He didn’t really even need 6.2, to say this.

Now, it comes down to how much more time long trips could take, allowing for the triangulation that a needed 25 minute “top off” may take. That’s all you need for a 400+ mile itinerary. Don’t buy the hype on range anxiety and you’ll believe Elon like, I promise, many Tesla owners already do.

I don’t get something, Hawthorne to Fremont is 360 miles – should’t a S85 be able to make it with only 1 stop? The screen shot above shows 3? Am I missing something?

Presumably you have choices… Miss one on purpose and it will advise on the next one, or stop early and it will recalculate future charging options.

I have a bigger problem with the SuperCharger map showing how far you can drive from the edge of coverage. If you drive 200 miles away from the edge, you cant get back unless you make other arrangements. Or maybe you get 1/2 way and it says turn around to the nearest SC, which is 200 miles behind you.

All in all, there is no substitute for being an aware driver. Same problem with GPS in the early days – People would drive into the abyss because “it told me to go there”.

They started with 36% state of charge though in that screenshot

You could not make Hawthorne to Freemont with only 1 stop unless, like Elon said, you wear diapers.

There’s more than one kind of range anxiety on a long trip like that.

Depending on SOC you may spend a lot less time charging by making 3 stops rather than 1. Remember that charging slows down as the battery gets full.

That’s the actual real benefit of all of this to a seasoned and reasonably aware owner. With some experience with our EV, we have a pretty good understanding of how far our cars can go under current circumstances. Optimizing total trip time is a bit more complex when it comes to on route charging, especially since the bottom 2/3 of battery charging is much faster than the last 1/3. Sometimes slower is faster.

This is actually NO different that how a conventional Gasoline car operates.
I have a Range of 320 miles, If I chose to go beyond that, I run out of fuel.

Another great update. Its 2015. I wish the other big automakers could do these over the air updates.

Interesting that they show a supercharger in Syracuse NY… I’m not aware of one.

439 Electronics Parkway

Under construction according to supercharge.info

In Liverpool, near Syracuse. “Syracuse” is the name of the station. 8 stalls.

Comments on TMC suggests it’s Tesla “coming soon” mao or something.

Also has Las Vegas NM (construction?), Albuquerque (site identified) and Trinidad, CO (site identified), which aren’t open.

So, when are we doing Lunch? NOw, on the “S”, what happens if you program in a destination and the computer says its has enough battery, but then 1/4 way through the trip it gets freezing cold and you have to run the defroster on high the rest of the trip? Sounds like its a bit early to say this is the “End of Range Anxiety”. I’d like to buy a Large EV, but I’m unsure about the “S”. Its a case of once bit, twice shy. THere were things about the roadster I was unaware of until after I purchased it and I fear there are even more things like that with the “S”. For instance, If left unplugged at 10 degrees fahrenheit outside, FROM A COLD START, how many miles do you lose overnight. Broder lost I seem to recall 55 or 65 miles overnight from a Hot Start. This was specifically ‘tested’, but he found out that info anyway. I’ve never seen any hard data to answer my question even years later. The more modern software update seems to solve some of the parasitic load problem but I have no info as to the cold problem. And… Read more »

I wonder if you can hit the acknowledge button to pass on an upgrade, if you really don’t want the new features?

No but you can sign the sales paperwork if you actuallly owned a model S. Not that any owners would do that. Most are features that you can choose to use or not. Some like some and others like others but haven’t seen an actual owner complain yet that the car is getting more and better feature rich with age.

routing is no need,valet mode is good,but for me the higher speed to 155mph will be nice here in germany, i hate the 125mph limit,if every bmw and mercedes has a 155mph limit.i cant wait to get my p85d

Interesting how Tesla put on “1st page” their enhanced navigation, which is just a basic of the EV features (Leaf, ZOE and others take into account the network for trip planning).
The very interesting items are the OTA updates that affect the HARDWARE of the car (driver assistance, automatice braking, valet etc..).
This is the real game changer: no need to upgrade the car to have these features. Tesla literally stepped in a new era for automotive. SOFTWARE upgrading. Awesome.

The Leaf’s onboard range calculator functions so poorly that owners call it the “Guess-O-Meter”. I think it’s safe to say that with this update, Tesla’s is much more accurate, and much more dependable. That’s not to say it’s perfect — as I pointed out in a post above, some variables cannot be accurately predicted, so a 100% reliable range calculator isn’t possible in the real world.

But surely with this upgrade, Tesla Model S drivers will have much less range anxiety than Leaf drivers.

Let’s see what Tesla will do. Surely, we can expect them to come up with a very good piece of software. Nevertheless, on the Renault ZOE (Sold in Europe only), the trip computer and the integration with the navigation system is very good.
I still believe that the greatest evolution Tesla showed us yesterday is the ability to control new HARDWARE items of the car with Software OTA updates.

I have a p85d and even if this car did not have any computer at all its truly the most fun car to drive
I also have a Porsche gt2 700hp and I like my tesla for its driving experience better

It’s time for Elon MUsk to boost his company stocks so here goes some more BS. He’s the cult leader and the media is the cult follower who believe all the BS he dishes out. Some day this hype will all end and reality will set in. In the meantime, let the followers enjoy this BS.

Ignore John. He is just bitter he can not afford a Tesla.

And what companies have you created jon doe???

That’s right, nothing so move along troll back to under your bridge or momma’s basement.
