Aluminium space frame for light weight and highest strength



Lower centre of gravity and transverse reinforcing struts for perfect dynamics
The overall vehicle concept has been designed with the lowest possible centre of gravity. That means a low connection between the drive train and the axles, as well as the lowest possible arrangement of the body-in-white components that contribute to rigidity. Examples include the connections between the front and rear sections and the occupant safety cell, which are resistant to bending and torque. These connections have been consistently designed to run along the lowest possible force paths. The result is not only a low centre of gravity but also a harmonious, and thus efficient, transfer of force within the vehicle's structure.

Another hallmark of the lightweight construction is the transverse reinforcing struts that are integrated into the body-in-white structure at the front and rear axles. The profiles connect the side members exactly at the points where the strongest forces act on the body-in-white when the vehicle is taking a fast bend. The advantages of this painstaking solution are a matchless degree of transverse rigidity and the avoidance of heavy secondary stiffeners or consoles.

Passive safety at the highest level
The aluminium space frame forms the basis for providing outstanding passive safety. The comprehensive range of standard equipment includes three-point seatbelts, seat-belt tensioners, belt force limiters, and up to eight airbags: adaptive front airbags, a kneebag each for the driver and front passenger, two seat-integrated sidebags and two windowbags for protection from side collision.
