The F700 has debuted at the 2007 Frankfurt Motor Show and represents Mercedes-Benz's proposal for a futuristic and environment-friendly luxury saloon.

For the first time in this class, the powertrain features a compact engine which allows for really low fuel consumption values and integrates a compact hybrid module with an electric motor.

Indeed, the engine is a 1.8 liters 4-cylinders gasoline unit, which showcases the so-called "Diesotto" cycle, combining controlled auto ignition (CAI), direct fuel injection and turbocharging, for a total output of 238 hp (+20 hp by the electric motor), comparable to that of a 3.5-liter naturally aspirated V6 engine.

As a result, the F700 can reach more-than-acceptable performances (a top speed limited to 200 km/h and a 0-100 km/h sprint in 7.5 seconds), while featuring an average fuel consumption of 53.3 mpg (23.8 km per liter).

Another technical highlight is the PRE-SCAN suspension: two laser scanners scan the roadway in front of the car and send data to the active suspension system which hydraulically compensates for detected hindrances, greatly improving the comfort.

Exterior Design

The design of the F700 Concept is characterized by soft, flowing forms.

The design language, named “Aqua Dynamic”translates the flow dynamics of a fish into the exterior shape of an automobile - using an idea that was at the base of the Bionic Car concept vehicle, unveiled in 2005.

With an overall exterior length of 5.18 m the F 700 is a little shorter than the current long-wheelbase version of the S-Class, but with the wheelbase of 3.45 m excels the production model by 28.5 cm.

The side view is marked by the tense curves of the roof contour and shoulder line, with lateral lines similar to those of the current CLS.

The distinctively shaped front wheel arches likewise are inspired by the S‑Class.

The headlamps are a futuristic interpretation of the Mercedes-typical twin-headlamp face. Two vertical rows of linear LED arrays with superposed lens have the function of driving lights.

A third vertical row of single high-performance LEDs are the daytime driving lights.

The headlamps integrate laser scanners that gather the roadway data for the active PRE-SCAN suspension. A similar scanner is located in the base of the mirror of the door and examines the area in which the door swings open for any obstacles.

The extremely spacious and flexible interior concept is emphasized by two large glazed areas in the roof.

The right rear door of the F 700 is hinged at the rear. Reversing the direction in which the door opens makes it easier to get into the REVERSE seat, which is the heart of the new seating concept: it permits individual seat and rest positions, both facing the direction of travel and in the opposite direction.
