The aerodynamic body – the Cd coefficient is 0.26 – has a length of 4.92 meters and is characterized by a redesigned front end with trapezoidal-shaped headlights that give the A6 a more aggressive look.
The interior will combine the more traditional features with new optional features such as the head-up display ambient lighting and the MMI navigation system with a 8-inch touch display and Internet services.
At launch, the A6 will be available with a choice of five engines – two gasoline engines and three TDI units – generating between 130 kW (177 hp) and 220 kW (300 hp) of output.
The Audi A6 hybrid will follow at a later date, with a powertrain delivering 180 kW (245 hp).
Compared to the previous model, it is a few millimeters shorter and lower; its width and wheelbase, however, have grown significantly.
The main proportions are defined by the long engine hood, the short overhangs, and the sweeping roofline.
The front end is characterized by the the large, low single-frame grill, which is painted in high-gloss black and has beveled upper corners merged with the sculptured surfaces.
The horizontal louvers and the wide, low air intakes underscore the width of the car.
The side view features a nearly flat waist line that underlines the length of the sedan It is visually contraster by the ascending lower character line and the above coupé-like roofline, which give the A6 a dynamic touch.
As with most Audis, the sheet-metal body is roughly twice as tall as the greenhouse.
The tornado line beneath the window edge runs across the entire flank; it forms a prominent shaded edge.
The design of the body shows an interplay between soft surfaces and precise, hard lines.
The rear end features two-part tail lights that echo the trapezoidal shape of the headlights. The subtle spoiler edge and the horizontal line that visually connects the tail lights enhance the width.
The rear lighting system forms a visually continuous band in the form of a wide, U-shaped curve; the turn signal lights form a strip that runs across the upper edge of the unit. Incandescent lamps illuminate the back-up lights and the rear fog lights.
The optional S line exterior package gives the car an even sportier look, with more prominently featured bumpers, grills on the air intakes, and diffuser insert.
The diffuser and the center edge of the front spoiler are painted gray; the fenders and the door sills sport S line badges. The sill panels stay the same color as the body.
The body combines aluminum and steel, which results in a weight reduction of about 15%.
Aluminum panels include all the add-on parts, such as the front fenders, the engine hood, the rear hatch and the doors.
In total, they account for more than 20 percent of the body and the total mass of the car is limited to 1,575 kilograms (in the 2.0 TDI version).
The car structure uses the same optimized combination of materials: aluminum struts in the engine compartment, crossmembers behind the bumpers, the bulkhead and the crossmember in the luggage compartment, are combined with high-strength steel components and tailor-welded blanks.
Thanks to the careful aerodynamic study, the body has a drag coefficient (Cd) of 0.26
