After premiering as a hardtop coupe in 2000, the Audi TT expands to include a drop top Roadster model for 2001. The 2001 Audi TT adds standard electronic stability control and a rear spoiler to improve handling. While the Audi TT fulfills desires of drivers on-road, the 2001 allroad provides buyers of the premium brand a commanding sense of more aggressive terrains. The 2001 Audi allroad is based on the A6 Avant wagon with sport utility vehicle attributes such as up to 8.2 inches of ground clearance, height adjustable air suspension and unique body work designed to better resist damage from stones or other debris. Available in overseas for five years, the Audi S8 finally arrives in the United States for the 2001 model year. A performance-geared version of the large A8 sedan, the 2001 Audi S8 is powered by a 360-horsepower 4.2-liter V-8 engine.
