At the end of 2004, a new A4 was introduced on the same B6 (PL46) platform with sedan, station wagon and convertible bodies. Both the chassis, suspension and engines have been upgraded. Innovative FSI engines with 2.0 L TFSI and 3.2 L V6 FSI liters and power of 200 and 255 hp (147 and 188 kW), respectively, were introduced. Both of these engines have four valves per cylinder, the previous 5-valve design was incompatible with the FSI injection system. As before, the multitronic gearbox is combined with a front-wheel drive system, and the 6-speed tiptronic with an all-wheel drive quattro system. While the car isn’t as fast or well-controlled as the BMW 3 Series, Audi can certainly boast of standard equipment, maneuverability, comfortable driving, powerful engines and a clear quattro system. There are really few negative comments - a lack of space on the back seat and the so-called turbo-engine turbolaga.
