2005 Audi A4 Reviews"Audi's best-selling line gets only minor changes for 2005. The A4 comes in sedan, Avant wagon, and Cabriolet convertible body styles. The 1.8 T versions use a turbo 4-cyl engine, the 3.0 models a V6. Sedans and convertibles offer front-wheel drive or Audi's quattro all-wheel drive; all Avants have quattro. Three transmissions are available. Quattros use a 6-speed manual or a conventional 5-speed automatic. Convertibles and the front-drive V6 sedan have a continuously variable automatic transmission. This CVT is available for the front-drive 1.8 T sedan in lieu of a 5-speed manual. The CVT provides variable drive ratios, plus six preset ""gears"" selected from the floor shift or steering-wheel buttons.
The high-performance S4 sedan, wagon, and convertible models have quattro, a V8 engine, and 6-speed manual or 6-speed automatic transmission, plus unique trim, sport suspension, and 18-inch wheels. Other A4s come with 16-inch wheels; 17s and 18s are part of Sport Package options that also include a firmer suspension. Every A4/S4 includes antilock 4-wheel disc brakes and antiskid system. Sedans and Avants add head-protecting curtain side airbags and front torso side airbags; rear torso side airbags are available. Cabriolets have front side airbags that provide head and torso protection, plus rear support bars that pop up automatically to protect occupants in a rollover. They include a power-folding top with heated glass rear window.
A navigation system is optional for V6 and S4 models. Dealer-installed satellite radio is available for all. For '05, optional OnStar assistance is dropped, and the xenon headlamps available for A4 sedans and Avants switch from high-beam to dual-beam units."
