2002 saw the arrival of the F400 Carving, an uncompromising, thoroughbred speedster with an extremely flat, elongated bonnet, a short tail and a weatherproof made-to-measure interior for two passengers. Once again a special focus was placed on driving dynamics, e.g. the Active Tyre Tilt Control (ATTC) system, which adjusts the camber angle of both the front and rear wheels when cornering or braking hard. A computer control system allows the outer wheels to tilt sideways on bends to a maximum angle of 20 degrees. The revolutionary design of the tyres with their asymmetric tread pattern ensures that they run on a section of high-friction tread rubber specially designed for cornering – rather than running on their inside edge. The inner wheels on bends and the vehicle body remain in their normal position. As a result, depending on speed and curve radius, the F400 sets new standards in directional stability, driving safety, speed and dynamism. Other key features include the electronic "steer-by-wire" system, the electronic "shift-by-wire" system (controlled using buttons on the steering wheel) and the 42 V vehicle power supply.
In 2003 the Mercedes-Benz F500 Mind was presented at the Tokyo Motor Show. The industry was stunned. Designed as a modern hatchback, this four-door vehicle was a mobile research lab, displaying more than a dozen cutting-edge technologies designed to enhance the safety, power and comfort of future Mercedes-Benz passenger cars. A special highlight is the hybrid drive, which uses up to 20% less fuel (particularly in city traffic) and generates significantly lower emissions than conventional engines. Another important research area is the development of innovative assistance systems to aid the driver. These include a night vision system, an innovative control and display concept with multivision display, and an ultrasonic driver information system.
