Mercedes-Benz shows the future of the superior touring sedan with its F 700 research car, which 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 5.17m long (17ft) F 700, with its innovative and spacious interior enables an entirely new and exceedingly comfortable mode of travel.
The F 700 is the world's first car that can recognize the condition of the road and level out the uneven spots with its active Pre-Scan suspension, further improving comfort. The forward-pointing Diesotto drive system, a 1.8 liter four-cylinder, 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 g/km correspond to consumption of 53.3mpg: 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 developed 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 fuel economy of a diesel. The drive system in the F 700, featuring two-stage turbocharging, 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 turbo-diesel.
The compact four-cylinder ensures that feeling of effortless, superior power afforded by a luxury sedan thanks to the two-stage turbocharger system that ensures good response and torquey pulling power. In addition, when the car moves off, the internal combustion engine is assisted by the hybrid module's electric motor. The maximum output is 238hp, the electric motor pitches in another 20hp, and the system's maximum torque is about 400Nm (295 lb-ft). The 0-to-62mph sprint time of 7.5sec attests to the dynamics of the F 700, whose top speed is limited to 125mph. Despite these performance figures, the consumption of the F 700 in the standard cycle is only about 53.3mpg, equivalent to CO2 emissions of 127 g/km - extremely low for an automobile of this category.The F 700 also sets standards with regard to road noise, 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 like a "flying carpet".
Equally innovative is the operating concept Servo-HMI. The display is not only gentle on the eyes; the number of controls also has been 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.
The exterior design of the F 700 shows that with this concept an extraordinary amount of space has been created for the passengers. The long wheelbase is a clear indication of this.
The exceptional efficiency of the overall concept is evident at first sight: its design is distinguished by soft, flowing forms. "Aqua Dynamic" is the name the designers have given this design idiom, where they translated the flow dynamics of a fish into the design of an exceptional automobile.
The interior concept interprets comfortable travel and well-being in a completely new way. With its Reverse seat, the F 700 breaks up the firmly established seat arrangement of conventional sedans and offers individual seating positions facing, or with one's back to, the direction of travel, always affording maximum spaciousness and supreme comfort.
The F 700 provides inspiring ideas for the technological future of Mercedes-Benz once again - like each of the research cars that preceded it.
