Audi R8 GT Consistent use of lightweight construction: 100 kilograms (220.46 pounds), trimmed – Production Audi R8 5.2 V10 FSI quattro has been a successful example of Audi’s lightweight construction philosophy. Its aluminum Audi Space Frame (ASF) body weighs just 210 kilograms (462.97 pounds). aluminum body panels joined to the frame with extruded profiles and cast nodes through a positive and frictional connection. Machine framework is made of ultra lightweight magnesium.
ASF body largely hand-built at the Neckarsulm factory complex in the manufacturing process. Very high strength body is the basis for proper handling of high-performance sports car, and it also offers both comfort and safety of first-class crash vibration.
Thanks to ASF body, the production R8 5.2 FSI quattro weighs only 1625 kilograms (3,582.51 lb) – with all-wheel drive quattro permanent and optional R Tronic transmission. This makes it all the more difficult for the engineers to once again achieve substantial weight savings. They took a complicated approach that involves every aspect of vehicle, and eventually came to rest in the scales 1 525 kilograms (3,362.05 lb).
Audi R8 GT windshield made of thinner glass, while the cell bulkhead between the passenger and engine compartments, and windows in the rear doors are made of strong, lightweight polycarbonate. All three modifications are saved nine kilograms (19.84 pounds). Rear wing is still good for an additional 1.2 kilograms (2.65 pounds); thin sheets of metal and pieces of shaved additional 2.6 kilograms (5.73 pounds) of aluminum hatch for containers 100 liters (3.53 cubic feet) baggage at the front of the car.
Long rear hatch is made of carbon fiber reinforced plastic (CFRP) – a gain of 6.6 kilograms (14.55 pounds). And the rear bumper of the same material sideblades save an additional 5.2 and 1.5 kilograms (11.46 and 3.31 pounds), respectively. With minimal weight and high strength, CFRP is an ideal material for a high-performance sports car, and Audi has extensive expertise in its use.
The engineers are also striving to shave every possible gram of weight of the technical components of R8. They shaved one kilogram (2.20 pounds) from the power brake system, four kilograms (8.82 pounds) of aluminum cap from the brake discs and 9.4 kilograms (20.72 pounds) of batteries. The engineers also found 2.3 kilograms (5.07 pounds) of air intake modules and 2.8 kilograms (6.17 pounds) in isolation of the engine compartment.
interior is also great potential to save weight-savings. The new, lightweight carpets account for 7.9 kilograms (17.42 lb) bucket seats with a chassis, glass reinforced plastic (GRP) account for 31.5 kilograms (69.45 pounds). Various detailed additional actions which targeted the interior, exterior and technology, such as a higher grade, mild steel for the exhaust system tailpipes.
