2014 Mercedes-Benz S500 Plug-In Hybrid Gets Official Reveal; Specs Pour Out

Hopefully That Graphic Doesn’t Come Standard

The 2014 Mercedes-Benz S500 Plug-In Hybrid is coming soon, so why not reveal it in all its glory today?

That’s exactly what Mercedes has done.

Consider this the official S500 Plug-In Hybrid reveal.

M-B had planned to debut the plug-in S500 at the 2013 Frankfurt Motor Show in September, but the automaker decided to jump the gun.

Here are the juicy details:

  • Fuel consumption of 3 liters/100 km (78.4 US mpg)
  • Emits only 69 g/km of CO2
  • Turbocharged 3.0-liter V6 engine rated at 328 hp and 354 pound- feet of torque
  • Electric motor adds 107 hp and 251 pound-feet of torque
  • Top speed 155 mph
  • 0 to 62 mph in 5.5 seconds
  • Electric-only range 18.6 miles

More details will surely come out in September when the S500 plug-in hits the Frankfurt stage.

Prcing?  It’s a Mercedes-Benz S-Class, so expect it to be through the roof.

The 2014 Mercedes-Benz S500 Plug-in Hybrid will arrive at dealerships in 2014.

“Electric-only range 18.6 miles” = fail


18.6 miles, Frankfurt motor show reveal => NEDC rating.

Unless you define fail “Will sail less than Model S” then I don’t think it’ll be a fail. Pure hybrid would be a fail, but not a PHEV, since PHEVs have particular advantages.

Uh, “sell”, naturally.

I would expect the S500 to have the 40 EV miles of the Volt, instead of less than the 21 EV miles of the Fusion Energi.

But I think we are still dealing with an issue of retrofitting batteries into platforms that were not designed to hold batteries which has restrictions. This is not a new platform for the S500 and the trunk is the only available space for batteries to go.

But this does allow the S500 to travel and live in congested European cities without a congestion fee.

especially since the battery is only half the width of the car, why not go the whole width and get 37.2 miles, it’s not like they can’t cover the cost of the extra batteries in the car. If you can afford to have night vision in your car you can afford to have a 20 kWh battery.

It looks to me like the battery pack and some related electronics protrude into the ICE version’s trunk thus reducing the trunk volume considerably. That seems like a fail similar to those of several current EV’s. Some potential customers might pull back if they feel that they really need a huge trunk.

I suppose when the entire ICE infrastructure must still be accommodated, finding empty space in the ICE version for the EV parts is tough. Maybe a purpose-built PHEV is the only way to make a really well-designed PHEV.

Interesting… another EV without Frankenplug (the pictured plug is a Menekkes without the DC Frankenpins).

Before somebody “informs” me that plug in hybrids don’t use DC quick charging, the Mitsubishi Outlander will have CHAdeMO DC quick charging with a 20 mile range before the oil burner is needed.

I did not catch that the Outlander will get CHAdeMO. That is going to put some serious stress on the Outlander 12 kWh pack (4C charge rate). Are they doing anything onboard to limit the current on the CHAdeMO chargers?

All DC chargers have full variable power output, it’s not a 50 kW on/off maschine.

Also the DC plug is a two way system, which allows you to use the Outlander’s battery and engine as backup power system.


Although it won’t have a long AER, at least it no longer qualifies as a gas guzzler at 78 mpg. Nice overall and good effort by MB.

Who will live if a Tesla hits this Merceds head on?

“Fuel consumption of 3 liters/100 km”

This is based on the European test cycle.

3 liters per 100kms converts to 94 mpg based on Imperial Gallons

94mpg of the larger Imperial gallons converts to 78 mpg of the smaller US gallons.

Then we must deduct roughly 34% to convert EU test cycle to US test cycle = about 51% mpg US

On the same NEDC test cycle the Chevrolet Volt gets 196 mpg US. In other words, the 78 mpg includes a reduction in gas consumption due to the battery pack. The 78 mpg is obviously not the gas-only mpg. The Volt NEDC gas-only consumption is rated at 47 mpg US (vs. EPA 35/40/37 city/highway/combined). I assume Mercedes-Benz strategically decided to release the gas-only mpg until a later date.

I wish articles like this would be more upfront in their reporting. The folks writing these stories (Eric Loveday, this means you…) must know by now how to fill in the missing context. And yet, all we get is lightly rewritten PR that is purposely misleading to casual readers.

That 18.6 miles of EV range will probably end up being estimated under the EPA rules in the US as being 13.

The 2011 Volt (before the small battery improvement in 2013) had a NEDC EV range of 52 miles (EPA 35) and the Prius Plugin was 14.3 on NEDC but was rated 11 on EPA which included some momentary use of the gas engine and so should really be thought of as 10 miles.

18.6 LOL that’s so funny!

The Volt rated at 38 miles AER gets anywhere between 25 and 65 miles AER, but this guy is so precise it gets EXACTLY 18.6.

It must be that legendary German engineering ‘snicker’

I think this is in response to the rumors that some EU cities will ban ICE engine vehicles from the center. I bet you it has a “save” button that lets you drive around all day at spewing out emissions whilst saving the charge in the battery for the last 5 miles in the city. It also comes in as being rated just below the 75 gCO2/km London congestion charge. Whats German for “compliance car”? Yes I know it won’t meet Californian laws but make no mistake this car is designed to drive through loop holes in tax systems not save the planet.

I don’t care if they ever make the Gen III (I think there are starting to emerge a number of cars that could get cheap enough for the masses) but I do hope Tesla takes 10% of the luxury car market in the EU and China in the next few years.
