2018 Mercedes-Benz S-Class PHEV Gets An Upgrade, 31 Mile* Electric Range

4 months ago by Mark Kane 16

China is the largest market for the Mercedes-Benz S-Class, so its not strange that German brand presented its new 2018 face-lifted version from Auto Shanghai.  But that is ok for the rest of us, because the new offering is also a global product.

As always, we could care less about the petrol-only offerings…it’s the plug we care interested in.

And the plug-in hybrid version of the new 2018 Mercedes-Benz S-Class will be equipped with a 13.3 kWh battery pack, which is nearly 53% larger than previous 8.7 kWh found in the current S 550 H.

According to Mercedes-Benz, range improves to 50 km* (31 miles).  As always, we will put a big (*) asterisk on that number, and consider Mercedes to be talking via the optimistic NEDC/Euro metric.

However, with the previous model’s real-world 19 km (12 miles), we’d be comfortable betting the 2018’s real-world/EPA range will be more like 30 km (19 miles).

Interestingly, Mercedes has also equipped the 2018 S-Series plug-in hyrbid with a higher power, on-board charger – up to 7.2 kW, which needs less than two hours to fully charge the battery.  A factory wireless option is also available.

The new interior, as one might expect from a new top-of-the line refresh from Mercedes, looks impressive:

    In China they are required to have 50 km range to get incentives and advantages. Expect all models that are also sold in China to get (at least) this range.
    BMW, Volvo, VW etc. will do this too.

    *could not care less

      I think that’s the US version, Nick. To my UK/Aussie mind it doesn’t make sense either (so I agree with you) but I’m getting used to it. ?

  3. Nick says:

    Do these have full performance while in EV mode?

    I’m still amazed that so far only GM and BMW have managed to crack that nut.

      I doubt it. The previous version produced 436 hp = 325 kW. That would be 25C discharge rate from the new battery, higher than other plug-ins. More importantly Mercedes can’t let go of the engine mystique. The previous version had a turbo V6, I doubt this will downsize.

    With wireless charging 30 miles is enough, can commute to work then recharge at work and just use fuel on the weekends.

    WOW 31 miles electric? How is it possible? WOW 🙂

  6. Rich says:

    What’s the EPA rated MPG once the 19 miles of electric range is depleted?

  7. Victor says:

    A few years ago I was a big supporter of plug-in hybrid electric vehicles. Today I am not. I think it’s time to go all electric. If Tesla and GM can produce electric vehicles with over 200 miles Electric range per charge for under $40,000 so can everyone else.

    1. zzzzzzzzzz says:

      $40,000 is around double comparing to similar ICE offerings from GM, and with unlimited range. Tesla didn’t made anything under $40k yet, just a lot of hot air.

      Maybe you are millionaire but please understand that general buying public just won’t increase their autoloan payments twice, even if they would qualify for double autoloan.

      Even plain hybrids are minority of the cars on the road, plugin hybrids are tiny minority. How are you supposed just switch everybody to BEV with their double price and range limitation?

      1. Philip Reeve says:

        You appreciate people who CAN afford the “too” expensive EVs because they’re the ones who make it possible for companies to develop less expensive versions.

        1. zzzzzzzzzz says:

          I appreciate them, but I don’t appreciate people who attack mass market solutions working in real life just because they don’t match somebody’s perfect dream in vapor-land. It is not the same.

    Ouch, that does look like a tart’s handbag on the inside doesn’t it?

  9. Mark.ca says:

    This car is incredibly beautiful! The electric range is an obvious disappointment….but wow….2 great looking cars on here today….this and the Audi.

    I hope there’s a ‘delete’ option for the quilted leather on the seats​ and trim. Not pretty!

  11. John goolkasian says:

    I would love this Car. 31 miles of EV range is enough.
    Problem is , such cars are not available in the US.
    I drive a plug in ELR as my daily driver and leave the S550 in the garage except for long trips. (Incidentally, I am averaging about 300 mpg of gas and have used only 35 gallons in 16,000miles of suburban driving.)
