Numerous technical solutions make Volkswagen’s "Dakar” prototype an uncompromising rally vehicle.
The prototype’s high-tech body, optimised for aerodynamic efficiency and assuring good visibility for the driver, primarily consists of carbon fibre-reinforced plastics. The actual body tips the scales at just about 50 kilograms. The basic shape of the "RT2” was developed by the Volkswagen Design Studio Braunschweig as early as in 2005 and subsequently refined in wind tunnel tests as well as by means of complex CFD (Computational Fluid Dynamics) calculations. But the body of the Race Touareg 2 has since been subjected to various detailed improvements. The most recent one: in 2009, for example, the drivers will benefit from an even flatter bonnet at the "Dakar” – which gives them better visibility of the permanently changing track conditions.
The Race Touareg’s backbone is an extremely torsion-resistant space frame to which the suspension components – double wishbones at the front and rear axles – are mounted. They, too, have reached the next evolutionary step in the direct development for the 2009 Dakar Rally. Modifications to rear suspension kinematics reduce the car’s roll movement and thus enable more precise handling. The space frame cage made of aviation steel has to absorb the enormous forces occurring on special stages and represents a safety aspect for the drivers in case of an accident.
