Text 2. Audi: Bodyshells, Space frame and

e-tron

Bodyshells

Audi produces 100% galvanised cars to prevent corrosion and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c.1975. Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which don't rust).

An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame). Audi introduced a new series of vehicles in the mid-1990s and continues to new technology and high performance. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique.

Space frame

Replacing the Audi V8 in 1994, the Audi A8 debuted with an aluminium space frame (the "Audi Space Frame" or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. The weight reduction is somewhat offset by the Quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop.

Audi e-tron

The next phase of technology Audi is developing is the e-tron electric drive powertrain system. They have shown several concept cars as of March 2010, each with different levels of size and performance. The original e-tron concept shown at the 2009 Frankfurt Motor Show is based on the platform of the R8 and has been scheduled for limited production. Power is provided by electric motors at all four wheels. The second concept was shown at the 2010 Detroit Motor Show. Power is provided by two electric motors at the rear axle. This concept is also considered to be the direction for a future mid-engined gas-powered 2-seat performance coupe. The Audi A1 e-tron concept, based on the Audi A1 production model, is a hybrid vehicle with a range extending Wankel rotary engine (роторно-поршневой двигатель, двигатель Ванкеля) to provide power after the initial charge of the battery is depleted. It is the only concept of the three to have range extending capability. The car is powered through the front wheels, always using electric power.
