PM's confirmation of previous beginning of the year Mercedes AMG 70, 700, F, S, C series car that will be shared with Chrysler products.
September 12, 2007 Unveiled yesterday at the Frankfurt Show, the Mercedes-Benz F 700 research car is arguably what a luxury touring sedan might look a few years from now. A small (1.8 litre) new design for the internal combustion engine in the form of the DIESOTTO motor (which combines the best properties of the spark-ignition engine and the diesel engine), a seating design that breaks with tradition to enable a spacious interior and a plethora of innovative technologies designed to create an exceedingly comfortable mode of travel. The technology which really interested us most was the suspension system - the car 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 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 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 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.
Equally innovative is the operating concept “SERVO-HMI”. The display is not only particularly gentle on the eyes; the number of controls also has been appreciably reduced and the menu structure has been made strikingly simple and self-explanatory. The driver can “discuss” more complex inputs, such as a destination for navigation purposes, in dialogue with an avatar, a virtual operating assistant.
