The new Audi A6 and the A6 Avant are stately cars, measuring 4,933 and 4,943 millimeters (16.18 ft and 16.22 ft) in length, respectively. The wheelbase measures 2,912 millimeters (9.55 ft), the width 1,874 millimeters (6.15 ft) and the body height 1,455/1,461 millimeters (4.77/ 4.79 ft), respectively. The body of the new A6 has an aluminum content of roughly 20 percent.
The cross-strut in the engine compartment and the cross-members behind the front and rear bumpers are made of aluminum sections. The front strut braces are highly integrated aluminum castings. Compared with comparable welded components of steel sheet, they save more than ten kilograms (22.0 lb) of weight. The integral subframe behind the instrument panel, the rear shelf, the cross-member in the trunk, the front fenders, the doors, the hood and the trunk lid are made of aluminum panels. This lightweight construction concept yields a weight savings of roughly 15 percent compared with conventional steel construction.
Furthermore, the bodies of the new Audi A6 and the A6 Avant include numerous hot-shaped steels, which combine extreme strength with low weight. They are used in the transition from the front section of the car to the occupant cell, in the A-pillars and the roof arch, in the center tunnel, the side sills and the B-pillars, at the transition of the side sills to the rear section of the car, and in the floor panel. In many areas, Audi uses tailored blanks – panels of various thicknesses within the component.
Other advantages of the bodies with their outstanding manufacturing quality: They achieve top values with respect to torsional stiffness, thus providing the basis for the highly precise handling and quietness in the cabin. Hydraulic elements minimize vibrations of the wheel suspensions, rear subframe and engine. Acoustic glazing in the front and side zones of the occupant cell is standard, and there are three seal lines at the doors. As an option, Audi offers insulating/acoustic glass all around and tinted privacy windows.
The new Audi A6 and the A6 Avant are also impressively aerodynamic, with cd values of 0.26 and 0.30, respectively. The paneled underbody channels air in a controlled manner, and air also flows through the engine compartment with minimal losses. Numerous details, such as the design of the exterior mirrors, provide for excellent aeroacoustics. The bodies also get top marks when it comes to passive safety, both in the event of a crash with other vehicles and for pedestrian safety. In the cabin, Audi’s adaptive restraint system offers outstanding protection.
