2004 Audi A6 Review

Exhibits excellent performance.

Reviewed by Automotive on


The A6 is the mid-level luxury car from Audi. Production began in 1994 to replace the Audi 100, and all models are available with a four-door sedan or a five-door wagon body style and a longitudinal front-engine front drive or permanent four-wheel drive, called Quattro.

The first generation had a sedan or wagon layout and ranged in power from a 1.8-liter inline-four turbo to a 2.5-liter inline-five with a five- or six-speed manual and a four-speed automatic. The second generation received many different engine options that ranged from a 1.8-liter inline-four turbo to a 4.2-liter V-8. The third generation models were sold as a two-liter inline-four turbo to a 4.2-liter V-8 with a six-speed manual, six-speed triptronic automatic, or seven-speed multitronic CVT. The current generation, introduced in 2012, starts with a two-liter inline-four through a supercharged V-8 three-liter. Transmissions include a six-speed manual, eight-speed triptronic automatic, a multitronic CVT, or a seven-speed S tronic DCT.

What's New

The 2004 Audi A6 added a Sport mode to the CVT transmission on the FrontTrak models. The full-time all-wheel-drive Quattro versions added a sunroof, and models added the capacity to add satellite radio.


The 2004 Audi A6 has an elegant and stylish exterior, though a little understated. A powerful and prominent grille on all models and aluminum-trim grille on the 2.7T and 3.0 sedan models extends to the bottom of the hood. There is bright trim around the windows and the rear features dual-exhaust tailpipes. The 2.7T has a sport suspension and a lower body with 17-inch wheels standard; this is optional on the 4.2. The 2.7T S model has 18-inch wheels and an RS-style rear spoiler. Gas-charged shock absorbers and rear and front stabilizers are standard on all models.


The inside is roomy and elegant, seating five. The instrument panel and other areas get real wood trim. Leather surfaces are standard on all seats, and front seats are 12-way power. The upper-tier models get full leather upholstery while the others get leather covering.

Performance & Handling

2004 Audi A6 engines include the 220-hp, three-liter V-6; 265-hp, 2.7-liter V-6; and the 300-hp, 4.2-liter V-8. All three perform very well, especially the V-8 model, which demonstrates impressive acceleration. The six-speed CVT auto-manual transmission is smooth and quick, and the five-speed automatic still gives the driver the option for manual shifting.

All models drive very quiet, even compared to other luxury sedans for the model year. Steering is very precise, and the driver feels in control. While responding well, it does have a heavy feel.


Anti-lock brakes and side-impact airbags are standard on all models. Rear side-impact airbags are optional. Airbags similar to side-curtain airbags deploy along the side windows on impact.
