The F 700 concept car is primed to be the star for Mercedes-Benz at Frankfurt with its DIESOTTO hybrid drivetrain and glitzy looks, but it's certainly not going to be alone up there on the stand. We know about the AMG C-Classes (sedan and wagon) and the ML 450 Hybrid, and you can add the S 300 BLUETEC Hybrid to the mix. Its hybridized BLUETEC 4-cylinder motivates the big sedan with a modest 224 horsepower and a not-modest-at-all 413 lb-ft of torque. The combination is good for 43.5 mpg and CO2 emissions of 142 g/km, and importantly, the system meets US emissions standards. While it's a show car, this package seems eminently doable, and it's not unreasonable to believe that it'll ultimately make it to production.

The modular technology concept from Mercedes-Benz includes optimised combustion engines and customised hybrid solutions, which are deployed individually or in combination depending on the vehicle class, application profile and customer requirements.

A prime example comes in the shape of the S 300 BLUETEC HYBRID with its unique combination of BLUETEC and hybrid technology that has given rise to the world's most efficient, most environment-compatible premium passenger car. As a 4-cylinder with hybrid module it develops a combined system output of 165 kW / 224 hp and a maximum torque of 560 Nm, a figure more reminiscent of a large-displacement V8 petrol unit. The luxury saloon delivers effortless performance yet consumes just 5.4 litres of diesel per 100 kilometres - equivalent to just 142 grams of CO2 per kilometre 57 grams or around 30 percent less than the current consumption and emissions benchmark in the S Class segment.

The S 300 BLUETEC HYBRID has the potential to meet most stringent emissions standards such as EU6 or the BIN5 standard for 50 US states.

      Finally something smart. May this drive train leak over to the E class and C class and may chrysler (that is to use the MB 2.2L crd om651) be smart to use this in the charger, magnum, 300C and minivans. Since the hybrid system is the same that chrysler is using.
      It may add $10,000 to the price of the vehicle. But to average 43mpg may be a good offset. Taxi magnum's or mini vans. Police hybrid chargers.

      Yeah, I would love to see this car made, and a E-class version (probably, they already have the E320 CDI).

      The diesel S would be an awesome long-haul cruiser. Limited only by your bladder and hunger, you could go forever.

      Any performance guesses?

      those MPG numbers are excellent! tough choice to make...prius or S-class :)

      is there going to be anything left to show at the show?

      43.5 mpg in a sedan that size @ 224 horsepower and 413 lb-ft of torque is incredible.

      Sounds like the future of green motoring to me...just hope the whole package is reliable.

      Sounds rather interesting. I wonder what the EPA ratings will be.

      I hope they learned from Lexus how NOT to do a full-size luxury hybrid.

        given the mpg listed, it would seem Mercedes has a handle on things, unlike say Lexus who tossed the “h” on the LS to grab a few sales in Beverly Hills.

      no need for performance guesses - 0-100 kph (0-62 mpg) in 7.5 seconds in the S-class. No numbers for the C and E 300 Bluetec Hybrid yet...
