In 2000, the moderate performance of this otherwise excellent, 3.0-liter V-6- powered, sedan was improved by the addition of two higher-performance versions: the 250-hp, 2.7T twin-turbo V-6 and the 300-hp, 4.2 V-8, both with Audi’s Quattro all-wheel-drive system.

Like the Golf, it has grown up in the intervening years and now measures 164.5 inches long and 72.5 inches wide, up by 5.4 and 3.1 inches, respectively. The most radical change is that it uses a combination of a unit body and aluminum space-frame construction, with 69 percent of the structure being aluminum and the remainder steel.
