Mercedes-Benz recently announced that the B-Class Electric Drive will come with a base MSRP of $41,450 in the US when it hits dealerships starting this Summer.

That’s the base price, but there are several options available, all of which will drive up that price.  It’s rather easy to option a B-Class Electric Drive to a price point above $50,000, but there’s one option available that we believe most all B-Class ED buyers will opt for:

P-58 – Range Package (25 – 30%)

Unfortunately, there’s no price listed for the range package in this leaked dealer brochure, but we do have a ballpark estimate in regards to range, both with and without the optional range package.

Note the 85 miles of range listed as a provisional EPA figure.  This is Mercedes-Benz’ estimate as to the range the B-Class ED will receive when rated by the EPA.  We should note that Daimler/Mercedes-Benz is almost always spot on in providing a range estimate, so expect the official EPA figure to be 85 miles (+ or – no more than 2 miles).

With the 85-mile figure in hand, some simple math (85 times 30% = 25.5) shows us that the range package boosts total range up to 110.5 miles.  That would be the high-side figure.  The low-side figure is (85 times 25% = 21.25) 106.25 miles.

As our own Tom Moloughney detailed a couple of weeks ago:

1) The amount of usable energy is 28kWh; that is not the total pack size.
2) The 28kWh represents what is available in “Standard Charge Mode,” which is what the car defaults to.
3) Like the Tesla Model S, you can select “Range Mode” before you begin charging and in doing so you’ll have more of the battery pack available, which will increase your range by approximately 15%

Perhaps the 15% figure was Mercedes-Benz providing us with a conservative number, or maybe the range package provides anywhere from 15% to 30% boost in range.  Regardless, this option will be hot and will make the B-Class Electric Drive a true 100-plus mile electric vehicle.

Aside From the 100-Plus Mile Range, The B-Class ED Has Plenty of Cargo Space Too

Aside From the 100-Plus Mile Range, The B-Class ED Has Plenty of Cargo Space Too

As Moloughney previously wrote:

“This means that by using Range Mode, the driver will likely have 33kWh (or even more) at their disposal. Obviously, this isn’t going to encroach on Tesla-range territory, but it will give the B-Class Electric Drive the ability to claim the longest all-electric range of any electric vehicle (aside from Tesla) available nationwide.”

So, if you desire the only non-Tesla (yes, we know the B-Class has Tesla components within, but it’s not branded a Tesla) 100-mile EV to soon be available nationwide (sorry Toyota, the RAV4EV is California-only), then the B-Class Electric Drive is your only choice.  Just make sure you opt for the range package.

Just over $50K with all the bells and whistles. That makes is cheaper than the loaded i3.

Not quite. The i3 fully loaded is $52,175. The Mercedes is $52,690 + unknown amount for range mode ($1000-5000?)

Are you sure the 25-30% isnt a build percentage
in other words 25-30% of the cars built ?
other possibility is that is a set of features that improve range (note the heated windshield) that improves winter range?
but no a larger battery

At the NY car show they said its just a button you hit before you charge so it can be charged more and you’d get over 110 miles… They didn’t say it was an option you had to pay for though…


So is the range package extra battery or just a button that let’s you utilize a larger portion of the battery?

Utilizing a larger portion of the battery would indicate a fairly cheap option (software). If it is a larger battery, expect the option to be very expensive (7 Kwh more battery). I’m leaning towards the larger portion of the battery. We shall see in July when it’s released.

If it follows the standard Tesla (and Leaf) format, it will be more like 15%… The difference between 80% and 100% charge.

The only way it could jump to 30% would be by unlocking a substantial amount of hidden reserve capacity in the pack (kind of like on a Tesla 40 versus 60 Kwh pack)….

Leaf no longer has 80% charge option.

What do you mean the LEAF no longer has 80% charge option… my 2013 certainly does. It’s called Long Life Mode. Use it everyday. 🙂

That Mode was deleted in the 2014 model year.

It’s great to see some progress in EV range. Don’t think even 110 miles of range is enough for serious sales numbers but it’s a step up from the current 80 miles norm.

The EPA range on the B is 85 miles. The i3 is 81. The Leaf is 84 miles. I don’t see a lot of improvement here.

I will bet that the “range package) is similar to an eco mode, heated windshield , insulated roof and door panels. an options package to improve winter range, NOT a larger pack or option to use more of the pack. this options sheet is being mis-interpreted.

“to soon be available nationwide”?
When is that? I thought I had heard vague comments about later this year or next year if ever. I’ll believe it when I see it.

It will be available nationwide by 1st quarter 2015. I got that straight from Mercedes Benz E-Mobility Program Manager Michael Schweizer

So, if I’m reading this correctly, it’s an option to allow the battery to be fully charged?

For a “Nominal Fee” of course….lol

No charge for “extended range” capability on the Tesla-powered RAV4 EV… best I’ve had so far is 130 miles of indicated range when using it. Is there reason to believe the B-Class ED would be any different as far as charging for this?

Okay, I just re-read the options list, answered my own question… damn…

The heated windshield will help keep the range in cold weather, and that hopefully is available on it’s own.

This could be just a fool’$ eco button, right? Just a conservative software driving mode that they feel like charging a lot for.

Tesla provided similar drive train to RAV4 Ev and Benz. Rav4 gives 110-120. That should be locked reserve.
Cheep trick

Ya….better wait and see the exact details on this range pkg before we get too excited. If it was simply a bigger battery or more battery availbale, you wouldnt really need a range button would you? It would just go farther.

Other thing I’m waiting on is TMS for battery pack? And do the windows and doors fold into the floor for open air driving, or is that a typo and supposed to say INSULATION, not ISOLATION. LOL

The German word for “insulation” is “Isolierung”. In Swedish, the word is “isolering”. When speaking English, Swedes commonly say “isolation” when they mean “insulation”, so I’m guessing that Germans make a similar, understandable translation mistake.

we also still have no info on the heater.
My guess is its resistance , if it was heat pump they would be proclaiming it.

Does this have the CCS quick charge port?

Nope. Just a 10kW L2 charger.

It looks pretty clear to me – the increase in range comes from a combination of the addition of a “Range mode” plus some efficiency improvements (heated windshield, improved insolation).

Opening up more of the battery pack for use seems to make up about 15% (range mode, according to Tom Moloughney), and the other 5% to 10% seems to come from the heated windshield and improved insulation.

What I can’t figure out is what the technical difficulty is that prevents the inclusion of fog lights?

Woah, range looks best after Tesla. I am excited about sales, because I think the good range will be very positive on sales. Most EV driver wish some miles more…

If it truly gets 100+ mile, sign me up for the range package and the premium package. 😀

Does anyone know this? If I buy this car in Feb of 2015, can I claim the tax break in April 15, 2015 for the year 2014?

Dec 31 is the cut off. So a Feb 2015 purchase has to be claimed for 2015.

Good range news, but will it really make a difference, for many?

In this price bracket, why does the relative added cost of DC-quick charging, or a range extender, seem like such an oversight?

110mi isn’t good enough to double the daily use of either of our cars. I don’t know how others calc a personal “BEV minimum”, but if I forget, I don’t want to be stuck. That’s how 40-50 mile winter days turn into a 140 mile minimum requirement. Otherwise, gotta have REx or DC access.

Anyone know if there is such thing as a “charge failure alert” function, that could wake an EV user, if he forgets, the EVSE fails, etc? Onstar is nice, but it doesn’t do this.

RAV4 EV e-mails me whenever it starts or stops charging. First thing when I get up, I check my phone and make sure it charged. If there was a problem, I still have some time to get some more electrons in before I have to leave the house. Toyota also provides a geo-fenced “Plug-in Reminder” e-mail option, which I don’t use. Due to the volume of e-mails, I set up a dedicated e-mail account just for the car’s notifications. That also let’s me see at a glance if it charged just by whether there are new mails or not.

I am pretty sure the “package” isn’t adding any more capacity. Probably just a Boolean software bit that gets flipped that allows a higher DOD.
So if that’s the case, by default, the Benz is carrying around that additional weight but you never get to use it unless you pay for the unlock package?

I don’t like the styling of the BMW i3 but the weight is excellent at 2700 lbs. I like the form of the Benz; but, I’ll bet it’s a heavy sucker.

I don’t like the cost of either and I think like Toyota, after their initial sales, they will both end up throwing money on the hood to move ’em.

What “Toyota” are you referring to exactly?

If it’s the RAV4 EV, then you are describing the opposite of reality.

The reality is there’s great potential demand for the RAV4 EV, but Toyota is suppressing its sales potential by keeping it to California (and Oregon? I think not even).

And then, of course, whining that it “loses money” on them. The mere statement is meaningless if you are seriously embarking upon a new-tech vehicle; the early years are investment, not a narrow gain/loss calculation. Otherwise you’d never innovate.

I bumped into someone here in Seattle who “imported” a RAV4 EV from a California dealership. Many dealerships there are set up to do it. I refuse to consider the option, on principle. No use rewarding such bad behavior, it only encourages them.

Get the Mitsubishi PHEV next year. That’s better and cheaper too.

The Toyota Rav4 EV so only sold in California, for CARB-ZEV compliance for model hers 2012-2014.

For 2015-2017 model years, Toyota will rely on the hydrogen compliance car. With 9 credits earned per hydrogen car, Toyota can make 1/3 as many cars for the same credit derived from the only 3 credits for each Rav4 EV.

Toyota has sold 1600 Rav4 EV’s so far, with 1000 to go before production stops.

Toyota doesn’t care at all about whether the RAV4 EV is a market success. It’s a compliance car sold in one state simply to get ZEV credits. Any incentives are only there to push enough out the door to meet their internal ZEV target. Supply is limited to ensure they sell no more than needed. It has nothing to do with innovation or developing EV markets.

Those of us that live in the other 49 states get tired of suggestions that it is a sincere effort to promote BEVs.

Popular Mechanics states that the B-class ED weighs a staggering 3929 lbs. It’s obvious that the B-class is an EV conversion of a car that wasn’t designed to be lightweight which is too bad.

Rav4 EV weighs just over 4000 pounds.

If that’s true, then I don’t know where the weight is coming from. Even if the pack is actually 35kWh, it shouldn’t weigh more than 250kg, and the motor is far lighter than the ICE it replaces.

The gas B-Class weighs 3100-3400 lbs, and a good chunk of that must be the engine.

Glad to see a new entry in the basic electric, small to mid size battery 16 to 30kWh. I sat in it at a recent car show and it was quite a bit more snug and lower to clamber into than my LEAF. So for me I still made the right choice. Other than Tesla… which is a year or so off in delivering my new dream car… the Model X. Sure hope I can afford it when it arrives.

Love my LEAF!

This car is another car on the list of cars that proves my theory that battery size and range don’t really have that much to do with the cars price expect for Tesla’s battery packs but that’s mainly do to Tesla’s having such monstrous battery packs compared to these runts. The reason why is the BMW i-3 and the Mercedes both have battery packs that are in low to upper 20 kilowatt. While the Nissan Leaf has a 24 kilowatt battery pack and gets 80 miles of range. Mercedes costs double the leaf and yet it’s battery pack is maybe only three or four kilowatts bigger then the leafs. While the car costs double the price of the leaf if not 70% more in price some cases. But at the same time this goes on the range isn’t really that different between the pricy car and the chippie. In a logical world the expensive car that is double the price would have double the range at least. I mean come on the Mercedes is breaking past $50,000 the same price as the never built 40 kilowatt Tesla. The only car that breaks these rules on range and battery size is… Read more »

Ocean Railroader,
You are comparing apples and bananas.

Also, check out my tip below on extending range. Rather, being free of range anxiety.

I have some good tips to occasionally extend range for ALL EV drivers.
1. Over inflate the tires: This reduced the friction, and will extend the range. Of course, this has other side effects, so only use once in a while.
2) Buy a portable generators that costs about $300-$400 adn weighs about 40-50 lbs. Carry it in the trunk for trips that might test the range/ Just in case you run out of charge, the small $300 generator can supply 15A for 10 hours with just 1 gallon of gas, to recharge and extend the range 🙂

Now, you should pay me $1K for these tips.

I am not sure this article is correct. The referenced page with option pricing is taken from the Dealer Ordering Guide dated 2-2014 that I uploaded in its entirety. This same guide also states about the Range Package “This enables in increased range of up to 17 miles.” You will find this info on pages 8 and 11. It also shows a lot of different exterior and interior color combinations. I think there is likely still a lot of misinformation out there about this vehicle.

It looks like the link to the document did not post.

Yes, on page 11:

“By pressing the range-button on the middle console(see highlighted below) prior to charging, the maximum charging level for the battery will be temporalily (sic) increased in the following charging cycle, therefore adding additional capacity.
This enables in increased range of up to 17 miles.”

Mercedes B-Class ED battery

33.2kWh usable- 126 miles
28.0kWh usable- 106.4 miles

@ 3.8 miles per kWh (263 wattHours per mile) * 33.2kWh = 126 miles

Range estimate based on steady 65mph indicated (100km ground speed) on dry, hard surface level road with no wind or cabin climate control with new condition battery at 70F.

The omission of chademo is really a shame, I know MB isn’t on that standard but in the Northwest, WA/OR we have so many already built…

Even better would be a $3500 Tesla SuperCharger option…


This “range button” they are talking about in the “middle counsel” sounds just like the same button on the LEAF.

It will bypass the normal 80% charge for a “100%” charge. Here’s my guess about the battery:

Mercedes B-Class ED battery

36.0kWh total – 100% SOC
33.2kWh usable- 95.0% SOC
28.0kWh usable- 80.0% SOC
1.0 kWh unusable- 2.7% SOC

Heated windshields, better heaters, etc, DO NOT INCREASE RANGE. They reduced the amount of range reduction from cold weather and energy used to counter cold weather effects.

So, to be clear, if your range is 85 miles today at 70F / 20C degrees with no heater use, the range when it’s cold will be LESS in otherwise identical conditions except temperature. Whatever that reduction is can be mitigated with battery heating, heated seats, steering wheel, and windscreen, and a proper heat pump cabin heater. The range, however, will not go above 85 miles.

Somebody asked above if the battery will have a Temperature Management System (TMS), and of course it will, just like every other Tesla powered vehicle produced.

Does this car have a heat pump?

I very seriously doubt it, only because it’s more expensive. They could have easily on any DC quick charge standard, but they didn’t.

No serious modern electric car can rely solely on “old school” charge at home only mentality.

A heat pump is less costly. In basic terms is an extra reversing valve on the AC system. The other method requires a tank heater, hoses, radiator in the cabin and extra HV components.

In many ways, this option is what a lot of folks considering the i3 wanted instead of a Rex…just “add” more battery . Many people still don’t view the i3’s Rex as really viable for longer distance travel (this next year will tell that tale), and thus the Rex is considered the extender for longer “local” driving. So., if that’s how the i3’s Rex will REALLY be used then is “more battery” really almost as good? I say “almost” because, as a Volt owner, believe me I appreciate the flexibility that a gas engine provides…as does my wife on her 600 mile round trip from Dallas to San Antonio this weekend…however, the idea of 6-8 gas stops in an i3 would likely have pushed her into taking her 20 mpg ICE SUV.

Considering the battery is the most expensive part of the car, it seems like it would not make sense to handle it this way (with a push button). The cost for 30% more battery pack is going to be substantial, so it would seem like its something you want access to all the time.

On a Model S, “Range Mode” kicks on a number of energy saving features around the climate control like limiting the AC or favoring the seat warmers over the cabin heater. Based on experience, it seems good for 10-15% more range.

This seems similar, although if the 25-30% is the actual range boost, that is pretty impressive.

BTW, this is different from what used to be called “range charge” and is now called “max charge” which was simply how much you charge the battery pack.
