2018 Mercedes E-Class Debuts High-Tech 48V Turbo Four

Mercedes is rolling out a series of new features, and they’re starting under the hood of the E-Class coupe and convertible.

While the revisions to the mid-range two-door models include new paint finishes, trim, and interior equipment, the big news here is the arrival of a cutting-edge new engine.

The 2.0-liter turbocharged four-cylinder in the new E350 coupe and cabrio border on hybrid thanks to their new 48-volt electrical system. The EQ Boost starter/alternator helps with ignition, low-end acceleration, coasting, brakeforce energy recuperation, and altogether running smoothly.

With 299 horsepower and 295 lb-ft of torque, the engine also performs closer to a six, running from 0-62 in 5.9 seconds (6.1 for the convertible) and top out at an electronically limited 155 miles per hour (250km/h)– all while returning 6.7 l/100km or 35 miles per gallon on the combined EU cycle.

Aside from the engine, Benz has added more color choices, the Energizing suite from the S-Class (now offered across the E-Class range), a teleconferencing system, and SMS alerts in case the vehicle’s damaged while parked. There’s also a new Night package for the convertible, featuring gloss black trim and special wheels.

These updates were announced initially for the European market, and extend to the E200 and E220d models as well. Look for the new engine (and other updates) to reach other markets – and models – in the US in the near future. Because the future is exactly what this new engine represents for Mercedes-Benz.

    2.0-liter turbocharged four-cylinder topping out at an electronically limited 250 mph? Impressive.

    • Rocc E. Normyss

      250 mph?? And it needs a limiter to hold it down?? Whaaaaa? Perhaps 150 is the correct number. Hard to believe this engine is capable of turning the gears at such a speed.

      • dtd

        What they mean is 250km/h which is equivalent to 155mph.

    • kello3000

      What’s most impressive is that it only returns 35mpg at that speed!

      • Rocc E. Normyss

        I’m sure they meant 350 mph, NOT 250. There, fixed it.

    • Kagiso Mutlaneng

      LOL I think they meant 250km/h (which is the standard in km markets). Hahahaha

  • pureworx

    lol i think it should read 250km/h

  • Gerald Michael

    250 mph AND 35 mpg? Where do I sign?

    • exeptor

      Plus the price is not that high and you have the comfort not like the other Mercedes ….. what was the name … Project 1 🙂 🙂 :).

      and taste too

    • Enter Ranting

      Add some giant fake grilles to that, and you’ve nailed it.

    • SteersUright

      Exactly. The entire MB lineup is mostly different color beans. Gone are the days of beautifully shaped rolling works of arts… It seems only carbon fiber can capture the intricate shapes they used to hammer out of metal by hand in the olden days. Interesting to see if when composites become more commonplace in body panels, we get better looking cars again.

  • Six Thousand Times

    The headline read to me like a 48-valve turbo four. The engine doesn’t produce 48 volts.

    • MarineCorpsX

      …yes, volts should be signed with capital letter. It’s a rule. 48V.

      • MarineCorpsX

        …also, I was thinking that they offered electric turbo engine. But… mah!

    • bechrbotmdolr


    • xDRAN0x

      its 48V turbo, like Audi’s. Lol @ 48 valves on a 4 cyl u guys

  • jon4uu

    Me thinks there’s a typo in the story somewhere…

  • Merc1

    Guys come on you know that should read 150mph, not 250.


  • Marc Gruben

    12 valves per cylinder? Now THAT’S cool! 😉

  • fabri99

    Right, but can we just talk about the perfection of that wine red colour on the coupe?

  • Sedat GÜNAYDIN

    It’s not 229 hp, 299 hp.

  • oh i thought you were saying 48 valves….

  • f1300

    Is this the reason why carscoops is looking for new Editors!? I mean, what numbers are actually correct in that article (rhetorically!)? Does anyone crossread that stuff?

  • Stiljust Dean

    Well, I wonder how long that little coffee-grinder is going to last; pushed to the limits? I’ll take my E550 coupe and it’s 25mpg on the highway

  • Stiljust Dean

    BTW, you know we are going to suffer with this small engine crap now that M-B management has decided not to import any more diesels. Thank you VW and the EPA. I know an owner of a GLK250 Bluetec that gets 35-45mpg and I’ll bet that diesel outperforms the turbo 4-banger.
