ABS and side air bags standard. Head protection air bags standard from 2000. ESC standard from 2002.
This nimble, stylish sports sedan offers a strong and refined 2.8-liter, 190-hp V6, along with a less-refined but responsive 170-hp turbo Four in 1.8T versions. The Four got a 20-hp boost for 2001. Also new are standard side-curtain air bags. The A4's ride is firm yet compliant. The optional five-speed automatic shifts smoothly and allows easy manual shifts. The front seats are very comfortable, though the rear is cramped. Audi's all-wheel-drive Quattro system improves handling and winter traction. The wagon version is called the Avant. The high performance S4 and S4 Avant have a 250-hp twin-turbo engine and firmer suspension.
