Mercedes-Benz B250e (B-Class ED) Road Test Review – Video

12 months ago by Mark Kane 17

The Mercedes-Benz B-Class ED, now called the B250e, isn’t a car found abundantly car in Europe (or really anywhere else for that matter), but Fully Charged managed to track one down for a test drive in the UK.

Over the course of the review, the build quality of the all-electric Mercedes was well appreciated, while also a big plus for host Robert was the regenerative braking control.

Still, it is one of those rare BEVs that doesn’t have fast charge capability, so you really only have the total range available to you once in a day (unless you often find yourself somewhere for a prolonged period of time – such as work).

The B250e has 87 mile/140 km EPA range, but ~107 miles/172 kms is available to be used (provided you have selected the toggle to do so)  via a 36 kWh battery.

Interestingly, the Mercedes-Benz B-Class ED is in fact, still Tesla-powered (powertrain and batteries).

In the U.S. about 4,000 have been sold up to date (full monthly sales by month for all US sold plug-ins can be found here), however the model has grown a bit dated, and sales have slowed recently with a lot of new product offerings entering the market.  Daimler has promised a new version will be coming shortly.

The price starts at $34,875 after federal tax credit in the US.

It’s just possible that this is close to an actual car review. Many thanks to the very generous Andy Seal who lent me the car for the day.
It truly is a very impressive machine with one rather major drawback.

    I’m surprised there is no EV without fast charge in Europe. But above and beyond that, 3kW it just murderously slow.

    The blue wing mirrors are too garish for me.

    It is a nice-looking car, but too many drawbacks for me. From his description it seems like it’s the most defining compliance car for Europe.

    I’m a little surprised he loves the regen paddles so much. They seem like a gimmick to me. I have a functional foot for controlling speed.

    1. Nero says:

      It has same charger as Tesla – 11kw

  2. The waiting game ... says:

    Building an EV without fast charge capability is so unserious and just plain stupid for a brand of that character. Mercedes Benz you know better than that! How much engineering effort would it take to do that. Not much I’m sure – So why didn’t you do it?

  3. bitguru says:

    I drive one of the other BEVs with no DC fast charge: a Ford Focus Electric.

    At least my FFE has a 6.6kW AC charger, good for about 20 miles of range per hour. It does seem odd that the B-Class Electric Drive has only a 3.7kW charger.

  4. Roman Mueller says:

    Our B250e charges with 11kw (3-phase 240V 16A). Quick power charge in the US plans to offer a CHAdeMO upgrade for it.

  5. vin says:

    Okay, I have a B-Class Electric in the driveway that we got last Thanksgiving.

    It has a 40A (9.6KW) charger on-board, same as the RAV4 EV, which according to the manual charges the 28KWh usable in about 4 hours. I’ve charged it with a 6KW EVSE, and it maxes that one out. Not sure where this guy get his info, though I did see one old article on this car that said it has a 3KW charger… I think it was written somewhere on the other side of the Atlantic. Maybe the euro ones don’t get the 9.6KW L2 charger?

    I also don’t have those blue mirrors or stickers on the side, thankfully. Have yet to see one like that.

    As for the regen paddles – I love them.

    They seem to have a following in So Cal… I see them more often than I see Spark EVs and FFEs, not as often as the 500e or LEAF. local dealer has four on the lot. Not rare in these parts.

    I think he’s totally right about the build quality… by far the best of any of the plug-ins I’ve had so far (RAV4 EV, FFE, Gen 1 Volt). And judging by the service loaners I’ve had from the local dealer (GLK, C300, CLA), build quality is on par with the typical entry level Benz.

  6. bitguru says:

    I didn’t think 3.7kW seemed right, but I did look it up and pull from a spec sheet. Maybe European B250e has different hardware from American B-Class Electric Drive.??

    9.6kW is more like what as remembered when I was considering a B-Class ED.

  7. midimal says:

    In EU Mercedes-Benz B250e (B-Class ED) charges max at 11kW (3 phase 3,66KW each)

    “Daimler has promised a new version will be coming shortly.”
    Link?
    I thought I’d recalled reading an updated version using an MB-designed drivetrain was planned, but the only thing I found when looking a few months was speculation that MB might do so.

    1. Jay Cole says:

      There is more than a few hints/clues/refernces out there over time. As one gets closer to a launch/product bastardization, OEMs tend to clam up a bit and you hear less(take the 2nd gen Volt specs as an example, or Nissan today)

      Tomas Weber (group board member:research and car development at Mercedes) on Merc tech plans to hit EU targets by 2020 at end of 201:

      “By 2020, we expect the energy density of battery technology to have doubled and the cost halved. Without any other changes being made, the range of the B-Class Electric Drive could increase to 185 or 250 miles.”

      Daimler already has said they are moving away from the Tesla componentry in future models, and when it was announced in March CEO Kroeger referenced they could supply the next generation themselves going forward.

      The scuttlebutt is that next gen B-Class ED powertrain upgrade is being developed/tooled inline now with the new petrol B Class (and CLA) for production at Daimler’s Kecskemet factory (in Hungary) for ~2018. Daimler disclosed in May it was plugging in some €580 million to plant for the changes…and more than half the amount specifically was allocated for new “state-of-the-art technology” and a new body shop.

      /take that for what you will I guess

      1. wavelet says:

        Interesting.

        I’d originally thought the B250e would make an excellent BEV: The ICE version is a very practical MPV, apart from the Mercedes-y upfront price, and with the added cost of a BEV drivetrain and governmental incentives, it could compete better with other EVs better than the ICE B-class does with ICE MPVs.

        However, the B250e ended up being a very low-profile car, PR-wise (in the US, a compliance car), so I thought maybe they gave up on it and would concentrate on the larger EQ platform (and the PHEVs, of course).

        I do hope they update it, and soon…

        1. wavelet says:

          …IIRC, the EQ platform is supposed to cover a range of vehicle sizes; the B-Class is very close w.r.t. dimensions to the GLA compact SUV (it’s a bit taller and has a bit more cargo space).

  9. MTN Ranger says:

    I forgot that they were still selling these cars.

  10. Terawatt says:

    I see them every day, but they are definitely not as common as LEAF, e-Golf, e-Up, Zoe, Soul, the triplets, or Model S. Still more common than Model X though. Probably about as common as e-NV200, which of course has been on sale for a much shorter time.

    Right now 40 are advertised on finn.no, the most popular online marketplace for cars (and most everything else) in Norway: http://m.finn.no/car/used/search.html?make=0.785&model=1.785.8111&engine_fuel=0%2F48

  11. Ed says:

    No DC Fast Charging is the only reason I didn’t buy this car!

  12. Mark Garnett says:

    We are a 2-car family and for the main 42 mile daily commute, the B-Class ED is perfect. Agreed without fast charge we must remember to charge every night at home; but a full battery every morning easily provides 25,000 miles per year without any extra day time top-ups (range would be substantially more if I could persuade my employer to install charging at my work place). For long weekend and vacation trips we use the other (ICE) car. Still means most of our annual motoring is EV with all the advantages (no UK road tax, minimal servicing costs, some free parking, huge MPGe) and the best/smoothest drive of my driving career.

  13. Mark Garnett says:

    Oh; I should add, normal paint colours are available but mine is the reverse of the reviewed car; metallic mid-blue paint with white mirrors, grill and side-writting. IMHO much better looking. And to answer RobW’s other key points, keyless ignition is available, its just an extra-cost option.
