The Frankfurt Auto Show is still a month away, but that hasn't stopped the car companies from dropping previews and tip-offs of new concepts they have planned for the show. Mercedes-Benz will have one of the biggest presentations at the event, showcasing no less than 18 new models and concepts cars, and the underlying theme for the show will be its new green initiative.

One of the concepts it has planned will be a 'radical' proposal for a large luxury car labelled the F700. Though this doesn't sound very green, the concept will feature Mercedes' new 1.8L turbocharged DiesOtto engine. The tiny motor is said to deliver an amazing 238hp and 295ft-lb. of torque, while returning fuel consumption of around 39 mpg in a large S-class saloon.

Other cars planned for the show include the new C-Class estate, more Bluetec diesel cars and the automaker's new electric hybrid range.

      Headlights bear a resemblance to the Genesis concept shown by Hyundai at NY Auto show last April.

      I'd be more interested in knowing how those goofy-looking headlights work.

      238hp and 295ft-lb. of torque out of a 1.8L four cyl diesel?

      Boost pressure must be like 50 PSI with a useful engine life of about 75k miles...unless it's made of titanium.

      give me w204 c class with this engine in US and i am in. 6 speed panora sunroof amg package for under 35k u cant beat it

      this engine may stop the diesel rush that might take place itne the US

      getting 45+mpg in a C-class would be just fine.

      imagine how the Prius and such owners will feel knowing that the Luxo car next to them doesn't need $10k worth of batteries to deliver the same mpg in real world driving.

      Looks cool and that turbo should be very tuner friendly!

      • 8 Years Ago
      for the world market, except for Australia....
      They want a V8 with 400 hp because the Turbo is too high-powered...

      If it's capable of 39MPG or so in something as heavy as an S-Class, what would it produce in an E or C-Class? 50-60MPG??? Besides, 238HP and 295 lbs of torque in the E or C would provide extremely good acceleration.

      Am I the only one who thinks this is too good to be true?

      Where is the 1 liter version making 120HP and 150 lb. ft. in a C Class? Wouldn't that absolutely KILL the Prius, Fit, and everything else?

      And imagine that as a ~6 liter engine - 700 HP and ~900 lb. ft. and you still might get a real world 20-25 MPG!

      It isnt a diesel. This engine is a variable compression Gasoline engine that is direct injected and is compression fired like a diesel.

      Shoehorn that 1.8L in a Smart and you have a deal.
