Mercedes-Benz F700

The Mercedes-Benz F700 is a concept car that Mercedes-Benz first showed to the public at the 2007 Frankfurt Motor Show. It was built to demonstrate the DiesOtto engine, a twin-turbocharged 1.8 litre four-cylinder with direct injection and variable compression that produces 175 kW and 400 N m. Its spatial ignition combustion works like a diesel at partial load, with the air and fuel mixture igniting by itself, while the car starts and runs under high load like a conventional petrol engine with a spark plug. An electric motor adds 15 kW for acceleration, and the car reaches 100 km/h in 7.6 seconds with a top speed limited to 200 km/h. The F700 also introduced Pre-Scan, in which two laser scanners in the headlights read the road ahead so that Active Body Control can prepare the suspension, a forerunner of the Magic Body Control of the 2013 S-Class.
