2006 Audi RS4

Automobile Mag reports about the 2006 Audi RS4:

RS is Audi's ultimate prefix, surpassing the S models and denoting maximum performance. U.S. buyers have only seen one RS model-the 2003 RS6, a wild-child A6 rumbling with a blown, 450-hp V-8. But the RS6 was actually the third Audi RS, following the 1994-95 RS2 (based on the Audi 80 wagon) and the 2000-01 RS4, a 375-hp, twin-turbocharged screamer fashioned from the first-generation Audi A4 Avant.

The Dynamic Ride Control (DRC)-introduced in the RS6-has been updated here and effectively suppresses yaw, roll, dive, and squat by diagonally linking the two pairs of dampers hydraulically. This wholly mechanical system provides a confidence-inspiring, ground-hugging cornering attitude that is particularly awesome on smooth tarmac, where the RS4 occasionally will lift a leg or two when going ten-tenths.

These enhanced photos provide a first official look at the Audi Q7, which debuts at September’s Frankfurt auto show. The seven-passenger Audi bears some resemblance to its Volkswagen Touareg cousin, but its aggressive and sporty styling signals a definite on-road bias. The Q7 will be powered by either Audi’s 3.2-liter V-6 or its 4.2-liter V-8, with the all-wheel-drive system from Audi’s RS6 supersedan, which has a 40/60 percent front/rear torque bias.
