The 2009 Audi A4 is redesigned, growing larger and gaining more power. Audi's top-selling car line features sedans and Avant wagons. Sedans will be powered by either a 3.2-liter V6 or a turbocharged 4-cylinder. Audi has not yet released specifications on the 4-cylinder, but the guess here is that it will be a continuation of the company's 2.0-liter turbo four, although probably with more than 200 hp. The 3.2-liter V6 makes 265 hp and is mated to either a 6-speed manual transmission or a 6-speed automatic. Audi's quattro all-wheel drive is standard on Avant wagons, as well as on the 4-cylinder sedan, when mated to the 6-speed automatic. Other A4s are front-wheel drive. Available safety features include ABS, traction control, antiskid system, front side airbags, rear side airbags, and curtain side airbags. Other available features include a navigation system; Audi's MMI control for audio, climate, and other functions; a self-opening trunklid; Audi Drive Select, which allows the driver to customize steering and suspension settings; keyless entry and starting (with in-key storage for service information); and a rearview camera. We have not yet tested the 2009 Audi A4.
