The DIESOTTO drive system is combined with a hybrid module and was featured in the Mercedes-Benz F 700 at the Frankfurt Motor Show in September 2007. It demonstrates that a large touring saloon is capable of returning a fuel-consumption figure of just 5.3 litres per 100 kilometres, enabling a drastic reduction in CO2 emissions without compromising on performance.
For example, the four-cylinder drive system with two-stage turbocharging fitted in the F 700 achieves the same level of performance as the current S-Class with a 3.5-litre V6 naturally-aspirated petrol engine.
Mercedes-Benz has created no fewer than 20 research cars since the Auto 2000 was introduced in 1981, but rarely has it revealed such a surprising glimpse of the future as the Mercedes-Benz F 700 Research Car. It's making its debut in this new luxury sedan. To refresh your memory, that engine produces 238hp and 295ft-lb. of torque from just 1.8 liters of displacement using some new technology known to many as homogeneous charge compression ignition, or HCCI, which "operates in compression ignition mode under light loads and spark ignition at other times" according to our own Sam Abuelsamid. The fuel mileage of the car with the DiesOtto engine is expected to be almost 40 miles per gallon, which is excellent for such a large vehicle.
The new F700 concept is just one of 18 vehicles that Mercedes is expected to showcase, including new Bluetec diesels and hybrids with both gasoline and diesel engines.
