First Drive: 2005 Audi A6
While the optional V-8 still has a displacement of 4.2 liters, changes to the 2005 version make it perform with more gusto; 30 more horsepower in a car that's about 175 pounds lighter. That combination makes the 4.2 model feel more athletic. The 3.2 FSI and 4.2 will be launched in quattro six-speed Tiptronic automatic form. A front-drive 3.2 will be introduced later in the year, most likely backed by a CVT. Both engines are electronically limited to a top speed of 155 mph.
Underneath, the A6 uses a four-link layout in front and a self-tracking trapezoidal-link setup in back, another bit of A8 technology that found its way into this midsize platform. The front suspension was moved forward 3.3 inches, improving axle-load distribution and shortening the front overhang. To reduce unsprung mass, the main suspension components are made of aluminum. Electrohydraulic rack-and-pinion steering works with Servotronic variable assist to make parking-lot maneuvers easier. Four-wheel discs are part of a new generation of Electronic Stability Program, combining ABS, EBD, and hydraulic brake assist to provide on-road safety.
ESP now automatically pulses the brakes imperceptibly to wipe water off, ensuring better brake response, even in wet weather.
Previous A6 models varied in length, height, and track width; now, all share the same body, which is wider, longer, and has wheels moved farther out to the corners. The expanded wheelbase and track (up to 2.8 inches wider in front and 1.9 inches wider out back), plus relatively little increase in height, add to the muscular look.
The A6 has a confident stance and conveys quality and taste. Admittedly, the grille-heavy front end takes getting used to, but the overall effect is a dramatic one and makes this new midsize Audi undeniably distinctive. It's found its place in the market as an upscale luxury sedan that also begs to be driven on winding roads. Blending style, performance, and comfort, it'll be a serious competitor for the likes of the 5 Series and E-Class.
