New Mercedes-Benz C-Class PHEV To Go 31 Miles On Electric Power

FEB 27 2018 BY MARK KANE 30

Mercedes-Benz announced the new C-Class sedan and wagon at the 2018 Geneva Motor Show – but now we’ve learned that two EQ-Power plug-in versions will be included.

Mercedes-Benz C-Class Saloon

The C-Class was already electrified through the 350e plug-in hybrid version, but now it’s time for the next generation EQ-Power powertrain with more power and battery capacity.

First of all, there will be two engine versions:

  • C300e – four-cylinder turbocharged gasoline engine
  • C300de – four-cylinder turbocharged diesel engine

The addition of a diesel engine (a rare sight in PHEVs) is something unexpected.

Battery size is expected to increase from around 6.4 kWh to 13.8 kWh for up to 31 miles (50 km) of all-electric range.

Electric motor power probably will increase by 50% too, from around 60 kW to around 90 kW.

There is no info on overall system power yet in the C350e and C350de (engines to be at around 200hp).

Sales of the new plug-in hybrids in Europe will begin later this year.

Not nothing, but close to nothing.
German people should demand the Government get out of the pocket of the auto industry and get a real EPA range of 40 miles minimum.

No, anything will save a lot of gas. If a person uses the full charge 260 days a year, 31 miles per day they could save 8000 miles (almost 13,000 km) per year of gasoline. This is actually about the same as the average German drives their car per year. So even with 25 or 30 miles range, most could eliminate about 80 or 90% of their gas usage.

The fact that they quote a 50km range means that they are still aiming for the minimum requirement to meet certain regulations. In Europe and China, you have to have 50km range to get the full benefits of being a plug-in vehicle. This is very disappointing. This is one area where Honda is clearly beating M-B with the Clarity PHEV. They didn’t go for the minimum required battery size.

This announcement also doesn’t mean that it will get a 31 mile AER on the EPA cycle either. It still may get a rating something like 0-22 miles Electric Range. The “zero to” means that it could not complete the test cycle without starting the engine.

I couldn’t agree more. Still, with that kind of range from a 13.8 kWh battery (and this being a brand new model), I have to assume that the range is at least calculated on the WLTP cycle. It probably would have been about 70km on NEDC…

Also, not sure about this model, but I’m pretty sure that a lot of the upcoming MB PHEVs will have CCS available. So there is that.

Why would they add CCS to a PHEV?

Mitsubishi has CCS on their Outlander.

Mitsubishi has Chademo on their Outlander, not CCS

Going for minimum here could still save many people more than 50% of their gas usage.

I have a Clarity PHEV and love it though, range is great and it is mostly EV. Its range is technically 0-47 miles. I prefer the 47 mile range to the mid 20s, as we would exceed that a lot more often, but even one with 25 mile range would still excel at the purpose of cutting fuel usage, which is the point, isn’t it?

One more comment – I also saw that the MB-USA web site has the GLC 350e Plug-In listed as an upcoming model. I have not seen any coverage of this fact yet.

Yeah.. i suspect this will be more like 20 on the EPA cycle, based on the size of the battery.

Even assuming only ~10kWh usable, 20 miles of electric range sound abysmal for a sedan. That’s barely two miles per kWh which sounds absurdly low.

What are you basing your suspicion on? 20 miles is really low for a sedan considering the size of the battery.

Since the Ford Fusion Energi (mid sized sedan) gets ~20 miles from a 7.6kWh battery, this will likely do the claimed 31 miles on 13.8kWh.

That 31 claim might be WLTP which would be ~28 miles on EPA, but 20 would be abysmal.

Looks like a very compelling variant of the C-Class. Such a shame they won’t sell the wagon here. The C350de sounds like the best of both worlds: silent electro-mobility in urban areas and bladder-bursting range and economy out on the highway.

Agreed, US EPA rating will be about 22 miles.
2018 M-B C Class PHEV, I’d like to introduce you to the 2013 Ford C-Max Energi

You’re about 5 years too late.

Yes, this is unfortunately still a Euro-compliance vehicle. Too bad, because I thought with the move to the EQ platform they’d be able to make fewer compromises and provide real PHEV utility.

EQA is the only Mercedes-Benz I’d own moving forward.

I think the range should be about 100km in winter, but it still serves a need.
People drive to and from work electric, and use gas/diesel for longer trips.
It is very common where I live.
People at work use these a lot. Only when extra cold, the electric will not work.

Average daily driving distance in the USA (commuting+errands, plus the few people who take long trips) is ~35mi / 56km. About 70% of US drivers have a <30mi round trip commute, so I think that should be the minimum for a PHEV; (esp. since most workplaces don't have chargers, and you need to allow for some spare capacity for winter and airconditioning, as well some battery degradation).
Average daily distance in Europe is a bit less, but not much less.

Depends on where you live, in Norway. Where I live there are outlets for block heaters many (work)places, and a lot of semifast (50), and slower (7-22) chargers outside public buildings, and stores.
Wireless chargers would be perfect for PHEVs (and regular EVs).
Block heater outlets do the job to charge short distance PHEVs like this, during a normal work day.
So most people would be able to use a car like this without using the engine, unless it’s a longer trip.
If they (PHEVs) had a 100km real winter range, the use of the engine would be even less. Would be cool as an option at least.

It’s funny how every new plugin hybrid does exactly 31 miles on electricity. There must be some regulation somewhere that demands this.

That’s because 31 miles is 50km which is the requirement under European regulations.

Whenever a gov’t makes a regulation, you can be assured that the vast majority will meet it, barely.

I have the 350e and I am not prepared to accept the range claim.
I am lucky to get 10 miles. Today in the U.K. with falling temperatures iI wouldn’t bother to charge it because firstly I am not able to get a range of more than 14 miles after a full charge.
Past performance of my car , which Mercedes tell me is normal, is for the full charge of 14 miles to drop to 13 the moment I open the door and then to lose around a further 4 miles after just one.
My plea would be for reviewing journalists to report accurately their experience in stead of the press pack info after a trip through the sun bathed streets of San Francisco as they did prior to me ordering mine. Once bitten twice shy !

The quoted range is under ideal circumstances. Cold weather is known to reduce output from a battery, plus if you are using the heater, it runs on the battery as well which steals away even more miles. PHEV and EV owners either already know this, or discover it when going through their first winter of ownership. It comes with the territory.

I am in my third winter and well understand your points.
Fact remains if the maximum mileage indicated in the summer is 16 miles after 100% charge, reported by the car and App, it plainly is not possible for Mercedes Range claim to be justified. The best I have ever achieved is 12 miles.
Motoring journalists should review cars under all conditions and then report the truth
