2007 Mercedes-Benz F700 Concept

With its Mercedes-Benz F700 research car, Mercedes-Benz redefines the idea of effortless, superior refinement: this concept for a future luxurious touring sedan shows how outstanding riding quality can be combined with high levels of environmental friendliness, and good performance with exceptionally low fuel consumption. Thus, the 5.17 meter long Mercedes-Benz F700 Concept with its innovative and very spacious interior design enables an entirely new and exceedingly comfortable mode of travel. The Mercedes-Benz F700 Concept is the world's first car that can anticipatively recognize the condition of the road and level out the uneven spots with its active PRE-SCAN suspension, further improving suspension comfort substantially. The forward-pointing DIESOTTO drive system introduced in the Mercedes-Benz F700 Concept, a four-cylinder with a displacement of only 1.8 liters, combines the strong points of the low-emission gasoline engine with the consumption benefits of the diesel drive. Its CO2 emissions of a mere 127 grams per kilometer correspond to consumption of only 5.3 liters of gasoline per 100 kilometers (44.3 mpg), extremely low for a vehicle of this class.

This is made possible by a forward-looking drive concept, the heart of which is the "DIESOTTO" technology - an advancement of the internal combustion engine thought up by Mercedes-Benz. With its novel controlled auto ignition (CAI), direct fuel injection and turbocharging, it combines the high power of the spark-ignition engine with the exemplary torque and great fuel economy of a diesel. The drive system in the Mercedes-Benz F700 Concept, as four-cylinder featuring two-stage charging, attains the performance level of a current S-Class car with a 3.5-liter naturally aspirated V6 gasoline engine or the 3.0-liter V6 turbodiesel.
