2005 Audi A4 rear.jpg

Also receiving updates is the A4, which Audi insisted on showing off despite the car's core being three years old. The 170-horsepower 1.8T engine makes way for a 200-horsepower 2.0, and the 225-horsepower 3.0 V6 gets replaced by the new A6's 255-horsepower 3.1-liter. The cabin has been restyled and Audi's Nuvolari grille adorns the front.
