Audi RS4 LeMans Front

Along with the A4's facelift midway through last year came a new turbo 2.0 4-cylinder and a new 3.1 V6, both with direct fuel injection and a lot more power. A4 Avant wagons shared these changes; A4 Cabriolets soldier on with the 2002 model's appearance and smaller engines. If you want an A4 in fast-forward, there's the 340-horsepower S4, and if too much is never enough, there's the upcoming 2007 RS4 with a whopping 420 horses, which will give the 2007 BMW M3 something to live up to and leave the Mercedes C55 for dead. Yikes!
