Audi A4 earns five stars and adds tech for 2009
The 2009 A4 sedan grows larger and more luxurious with Drive Select, a Bang & Olufsen 505W system, and improved fuel economy. It carries a $40,825 starting price for V6 models, with quattro and automatic transmission, while a front-wheel drive line will arrive later. The A4 faces rivals like the Mercedes C-Class and Infiniti G37, and offers enhanced rear legroom and a refined interior, though its V6 power trails the G37.
