The Mercedes-Benz F700 is a concept car produced by Mercedes-Benz. It was first revealed to the public at the 2007 Frankfurt motor show.
The F700 is powered by Mercedes' DiesOtto engine, so called because it combines elements of diesel and petrol (Otto cycle). The concept engine displaces 1.8-litres, and features twin sequential turbochargers, generating 177 kW and 400Nm at unspecified engine speeds.As a result, the F700 has performance equivalent to the Mercedes-Benz S350, with a fuel consumption rating of 53 US MPG or 4.43L/100 km.
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 F 700 with its innovative and very spa-cious interior design enables an entirely new and exceedingly comfortable mode of travel. The F 700 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 F 700, 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 con-sumption 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 for Mercedes Benz F700 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 F 700, 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.
“Our goal is to make the gasoline-powered car just as economical in consumption as the diesel. The new DIESOTTO concept is a major step in that direction, combining the best properties of the spark-ignition engine and the diesel engine,” says Dr. Thomas Weber, Board member of DaimlerChrysler AG responsible for Group Research & Mercedes Car Group Development.
The F 700 also sets standards in regard to road roar, tire vibration and suspension comfort. With two laser scanners the active PRE-SCAN suspension scans the roadway in front of the car. The hydraulically controlled active suspension proactively compensates for detected hindrances, enabling entirely new comfort characteristics –a “flying carpet” feeling.
