Tesla Model S Range After 11 Months, 28,000 Miles


60 kWh Range

60 kWh Range

Battery degradation impacts every electric vehicle out there, so how does the Tesla Model S fare?

Well, 28,000 miles, and 11 months.

Rated range is showing 206 miles on a full 100% charge on Firmware 5.9.

Even though 206 is displayed, I am still getting approx 207-209 Rated Miles.

My Delivery Day Range was 209 Miles.

Says Tesla Model S owner and YouTuber KmanAuto.  Kman owns a 60 kWh Model S, which is EPA rated at 208 miles of range.

It seems as though the range of this particular Model S hasn’t diminished as of yet.

To the Model S owners out there, we ask: have you seen your rated full-charge range drop over time?  If so, by how much and what’s the age and mileage of your Model S?

How is he charging? I see 40 amps defaulted on the screen. Is it supercharger enabled? If so does he use a supercharger much?

He can Supercharge, and posts a lot of videos of him charging in Wisconsin & Chicago.

Thats good news.

and he’s driving a 60 kwh
which will be the next vehicle

and on another note:

We have VOLT 60K mile drivers on the Volt with zero miles reduction.

Well, given how huge the SoC buffer in a Volt is, that’s hardly a surprise. When you devote over a third of your battery capacity as a reserve, there’s plenty of room to ‘adjust’ your range..

I heard the SoC buffer in the Model S is almost similar to the Volts in absolute kwhs.

My understanding is that the entire pack is 85kW of which 81kW are exposed for regular use.

Have an S85, 10 months, 24K miles.

Delivered with a rated range on 269, current max charges to 267 rated miles. The “rated miles” is a bit tricky as Tesla has tweaked the algorithm used to computes rated miles with the various SW updates we have gotten.

My “ideal miles” range remains at 300, so I would guess I have not lost anything off the battery pack.


IMHO this performance beats the heck out of any similarly-powerful ICE vehicle.

At 20k-30k miles you’ll start feeling, at the very least, your energy efficiency not quite as good as upon delivery. Especially with large engines.


I think you are.

Generally, ICE engines need to be “broken in” before attaining best efficiency.

Then they need to have regular oil and filter changes to keep max efficiency.

Some modern spark plugs last a good 100k miles near peak efficiency.

Then efficiency drops after 100k. But that may be due to people thinking investing in regular maintenance on such an old/high mileage car is not a good value proposition.

I think about it a different way–I do not expect a lot of drama from my MS as it ages Sure, I expect some slow degradation of the battery pack over time. I’ll probably cross 100K miles in another three years, but based on the first 10 months, I don’t expect ownership it to much different than today.

Now, I could be horribly wrong about this and rue the day I typed this comment, but I don’t think so. 🙂

It is impossible to judge battery degradation by the displayed estimated range. When I bought my EV, initially it showed 82 miles. In 3 months, based on my driving habits, now it shows 105 miles when fully charged. Did the battery improve that much?

We can’t use this method at all. The batteries need o have a ‘charge meter’ showing how much charge is left, which shouldn’t depend onpast driving habits. I think, this needs to be mandatory in EV cars. California is pushing for this now.

As for Nissan, we have heard several reports of severe battery degradation for early LEaves.

On the MS, “rated range” and “ideal range” are not based on historical data, simply an algorithm based on SoC. The Energy App does base “projected miles” based on recent driving behavior.

Rumor is that one of the impending SW updates will show SoC directly.


Hi there, I’m wondering what’s the loss in efficiency when you load up the car? “Real world” road trip. Say, for instance, you were to have 2 adults, 3 kiddos, a wiener dog in a crate, and about 75lbs of luggage. What would your actual range be? what % would you lose? I’m trying to gage (just guessing if it’s possible really) if the new Model X with 270 mile (EPA) range would make it 250 miles from our house to the grandparents in real life… THX!

P85 14 months old, 31,771km.

Started at 385km rated range, after a winter and a few software updates, rates range is now 365km.

Uh . . . well that is just great. But that is just what the software is telling you. Perhaps it was sand-bagging initially.

I don’t think that was the case. In fact I think Tesla was asked by the EPA to make their range estimates more akin to real life than they had been in early firmwares. So the numbers we’re seeing now are both more realistic and seemingly show we’re not losing much range even after heavy use.

So what, wife’s Focus EV is little over a year 14,000 miles and getting even better range at about 93 miles on the battery. Thats before she starts and around the same when she gets home. (mile driven + Miles remaining=Around 93 Miles). This story a waste of time…

Better range then what she was getting when she first bought it that is…

always has to be one ass in the bunch eh…

Friends don’t let friends drive Fords.


Oh thats right! If you ever say anything that you are not impressed with anything Tesla the jack asses come out of the woodwork to put you down, insult you and dismiss you. Sorry to post anything not praising Tesla!

I take my comment back… WOW Impressive! Tesla battery almost the same after 1 year 28,000 miles! Never saw that before. Best car ever! Great story!

John, when you start off your posting with “so what” you were just asking for trouble. Even if your wife’s Focus can match or beat the Tesla’s battery endurance, thats no reason to dismiss the car. Thats but one facet of the car and its safe to say any working Tesla would eviscerate your wife’s Focus in a race of acceleration or range. Face it, Tesla has aleady changed the world in ways unmatched by anyone. Although i do not yet own one (but i own a Volt, which is a fabulous car) i think about getting one every day of my life. I cannot say that about any other car. In fact, i cannot say that about any other thing. Im obsessed you might say. And i know i am not alone. Now how many businesses can match such marketing success? None that i know of. So when you dismiss Tesla, you dismiss the dreams of a whole lot of people. So dont be surprised if your arrogant dismissal is met with a vengence from a whole lot of people. Because Tesla is unmatched in a whole lot of important ways including customer loyalty.

Agreed. The estimated range is a software thing. A true way will be to measure the charge stored, not estimated range, which depends on software algorithm.

so no degradation at all, cool

I’d be interested in revisting this at year three of ownership. I’m just curious as it is a new vehicle.

Dont worry, I will keep everyone updated. I hit 30,000 miles almost exactly 1 year of ownership (1 day off). Now that I am also using my Model S as a Limousine, my mileage should increase greatly. I’m looking at voiding my battery warranty due to mileage in less then 2 1/2 years. I should have 60,000 on my car by End of 2014, and at least 75-80,000 by my 2 year ownership date.

I had to click on your link to figure out that you are Kman Auto. Thanks for sharing all the info on your Model S experience.

Keep providing the updates on the battery, and how every thing else ages in the Model S. There are many here stalking used Model Ss for the future 🙂

What is your average Wh per mile?

Christopher Allessi II

Fair weather, no Heat or AC: 230-280w/mile
Air Conditioning in Range Mode: 280-310
Air Conditioning in Standard : 300-380
Heat in Range Mode above 35*F: ~400
Heat in Standard below 35*F: 400-650

I got my 85 in April 2013. 19″ wheels. I now have about 36k miles. With 5.9 firmwware, my “rated range” is 260-265 on a full charge. This could be a reduction of about 10%, I’m not sure. Under good conditions (warm dry roads, no AC, speeds of about 60 mph), I usually beat the rated range by about 10%. BTW, I still have two of the original tires on the ground.
In comparison, my Leaf lost over 30% of it’s capacity in 25k miles. Nissan refused to fix it.

If you are at 260 miles rated range. You lost 2% (maybe less if you re-balance the pack). If you are at 265 miles rated range, you lost 0%.

So you know, Tesla had to change 300 miles to 265 miles with software update to reflect EPA range. The 300 mile number has been moved to ideal range.

I have driven 45,500km and lost maybe 1 or 2 km of range on our 85kW Model S.

We are also on v.5.9 of the firmware and have the two front tires as originals. 🙂
