A STRONG competitor for the BMW 3-series since its Australian launch in 1995, the Audi A4 still holds its own today despite upgrades and new models from its main protagonists. It offers a wide range of configurations from front-wheel drive to four-wheel drive and four-door sedan or station wagon. Performance in the base 1.8-litre engine is adequate only while the suspension offers a good combination of comfort and road-holding. Four-wheel drive and turbo versions add to the dynamics, and the price. Disadvantages are the tight back seat and slightly over-assisted power steering.
