2005 Audi A6 Review

Shines with an elegant interior and great performance.

Reviewed by Automotive on


The 2005 A6 falls into the third generation of executive cars manufactured by German carmaker Audi AG. The first generation of the car, named the C4, sold as the successor to the Audi 100. The 2005 Audi A6 belongs to the C5 platform and sells in the same class as the Mercedes-Benz E-Class and BMW 5 Series.

The first generation of the Audi A6 debuted in 1994. It initially sold as a fourth-generation Audi 100 with a facelift and a rebadge. The A6 badge results from the then-new alphanumeric nomenclature adopted by Audi.

The second generation of the car uses the Volkswagen Group C5 platform, and it comes with a completely new list of engines. The new generation sees Audi improve the quality of the car by a significant margin, making it a direct competitor to luxury sedans such as the BMW 5 Series and Mercedes-Benz E-Class for the first time. The exterior design gets modernized, and the fastback styling sets a trend for all other Audi cars.

The 2005 Audi A6 starts a new generation. The new model, which has been designed by Walter de’Silva, starts a visual evolution with the second-generation A6. It measures longer than the old generation and incorporates the brand-new single-frame grille. The 2005 Audi A6 also has the ?Tornado Line.?

The Range

Body Styles: sedan, five-door wagon
Engines: 3.0-liter V-6, 4.2-liter V-8
Transmissions: five-speed automatic
Models: Audi A6 3.2 Quattro, Audi A6 4.2 Quattro

What's New

The Audi A6 gets redesigned for its 2005 model year, with new styling, more room, and better engine power. The wheelbase increases by about three inches, but other dimensions remain the same. The engine options show revision, and the 2005 Audi A6 marks the introduction of Audi’s MMI operating system.


The most talked-about exterior feature of the 2005 Audi A6 is its new front grille. The A6 marks the first Audi car in the U.S. market to use the single-frame grille, and this particular exterior feature makes it stand out among its predecessors and current competitors. The basic shape of the A6 seems similar to the Ford Five Hundred, but the similarities remain more of an afterthought.


The interior of the 2005 Audi A6 shows a huge improvement over its predecessors. A larger wheelbase and wider track means that the interior looks more spacious than before. Headroom, shoulder room, and rear legroom increase, and so does the trunk capacity. The quality of the interior does not disappoint either. The interior uses high-quality materials, and the trims and colors have been chosen well. The seats feel supportive and comfortable, and Audi’s Multi Media Interface or MMI system proves much easier to handle than the respective system on its BMW and Mercedes-Benz counterparts. Nevertheless, the MMI system still proves a little difficult to operate, and even small tasks, such as adjusting the seat heater temperatures or saving a radio station, involves delving deep into the system.

Performance & Handling

The 2005 Audi A6 comes with a refreshed lineup of engines. A 3.2-liter V-6 serves as the base engine, and the 4.2-liter V-8 remains an option. The V-8 may seem familiar to some because it has been sourced from Audi’s performance-oriented S4 sedan, but the freshly designed V-6 uses direct injection. This direct injection feature is important because it allows better control over the energy deliverable by the engine.

This precision allows a V-6 engine that delivers 255 horsepower and 243 lb-ft of torque to deliver astounding fuel economy figures. The new technology also gives the A6 better performance and torque than in previous versions. Despite this, the Quattro does not make for the fastest vehicle in its class. Nevertheless, the car offers a very luxurious and elegant driving experience. Handling characteristics feel firmer than expected, giving the driver lots of confidence. Though the body roll remains moderate, the car still feels quite light and sporty.


The new 2005 Audi A6 offers several different safety features standard, including anti-lock brakes, an electronic stability system, and a brake force distribution system. The Insurance Institute for Highway Safety gives the Audi A6 its highest rating of ?good? in terms of frontal-offset crash tests for head, neck, and chest safety.
