2011 Audi A6 first looks

The next-gen 2012 Audi A6 will have a 50% lighter chassis thanks to the use of an aluminum ASF II spaceframe. It will consist of a conventional steel chassis.

The standard suspension will use traditional steel coil springs, while an optional air suspension will also be available. Audi’s Drive Select system will also be part of the offerings, so even if you don’t opt for the air suspension you’ll still be able to adjust the steering, throttle and damper settings.

Expect to see a fully revamped powertrain lineup that could consist of all forced-induction engines. On the low end, this A6 may introduce Audi’s potent 2.0-liter, turbocharged four-cylinder as the base engine. Audi’s TTS coupe already has a 272- horsepower version of that engine, so it wouldn’t be giving up much power to its competitors’ entry-level engines.

Midgrade models will likely use the 3.0-liter supercharged V6 already available in the current A6, while top-of-the-line versions will get Audi’s new turbocharged 4.0-liter V8. That engine will likely offer an eight-speed automatic transmission or an optional seven-speed dual-clutch setup.

An official unveil of the 2012 Audi A6 is expected at the 2011 Detroit Auto Show, with sales beginning later in the year.
