Mercedes Benz F700 DIESOTTO.

The F700 'research car' previews Mercedes-Benz's current thinking on how to replace a car as good as the S-Class - and it's a lot more radical under its gold-painted skin than it looks at first.

It aims to take ride comfort to a new level by anticipating the condition of the road and levelling out any unevenness using an active hydraulic suspension system called Pre-Scan. Laser scanners in the headlamps check out the road ahead and set the dampers accordingly. The 5.17m-long F700 also showcases developments in reduction of road noise and tyre vibration.
