The 2.8 sedan gets a valve job resulting in 18 more horsepower and additional torque. Side-impact airbags are standard, as is traction control. Opt for the automatic and you'll get the same Tiptronic technology that allows Biff to manually shift Buffy's 911 Cabriolet. A new station wagon called Avant debuts, while the A4 1.8T gets new wheels, a sport package and an ambient temperature gauge. New colors and stereo improvements round out the changes for 1998.
