2005 Audi A8 Review

A classy, full-size sedan that competes with the bigger names.

Reviewed by Automotive on


The 2005 A8 classifies as a full-size luxury sedan manufactured by Germany-based Audi AG. The car debuted in 1994 as a successor to the Audi V8. The 2005 model represents part of the second generation that began in 2002. It earns recognition as the first mass-market car to use an aluminum chassis, which Audi markets as the ?Space Frame.? The first generation of the A8 debuted in Europe in 1994, and production began later that year. However, the U.S. market saw the A8 only after three years, when the 1997 model year made its debut.

The Audi A8 proves different from its predecessor in that the former used the then-new Volkswagen Group D2 platform, marketed as the ?Space Frame.? This particular frame helps reduce the car’s weight and improve rigidity. The second-generation version, in which the 2005 Audi TT falls, began in late 2002 in Europe and in early 2003 in the U.S. The 2005 Audi A8 contains new engines, including the top-line W12 engine.

What's New

The 2005 Audi A8 comes with a standard wheelbase version for the first time. Other features introduced in the same year in the A8 include the tire pressure monitor, LED lighting on door handles, mirror controls, and rain-sensing wipers. New optional equipment includes a keyless starting and entry system, a wood shift knob and steering wheel, power door closers, and satellite radio. The horsepower of the engine increases from 330 to 335. The six-liter, W12 engine, which delivers 450 horsepower and 428 lb-ft of torque, also makes its debut with the 2005 Audi A8.


According to Audi, the 2005 A8 combines clarity, elegance, and grace. The extended version of the A8 sits on a wheelbase of 121 inches, which stretches five inches longer than the base version. The front end sits low, while the tail sits higher. The high beltline that meets the taillights adds to the sporty appearance of the 2005 Audi A8. The car comes fitted with seven-spoke alloys on 17-inch tires, but 19-inch and 18-inch tires with different rims remain available as well.


The 2005 Audi A8 holds up to five occupants inside, and it offers enough headroom and legroom for everyone inside. The seats feel supportive and roomy, and they come covered with high-quality Valcona leather upholstery. The power seats offer ventilation, heat, and even massage functions. The dash and other interior elements features a fine wood trim made of Beige Grained Birch or Amber Vavona. The 2005 Audi A8 includes a premium Bose surround sound system fitted with 12 speakers and a CD changer. The rear has lots of legroom even for tall occupants. In fact, legroom remains plentiful even with the front seats fully stretched back. The contoured recesses offer adequate headroom for tall occupants in the rear, but some people may feel a little claustrophobic.

Performance & Handling

The 4.2-liter V-8 in the 2005 Audi A8 generates 335 horsepower, and it mates with a six-speed automatic transmission with the Tiptronic and Dynamic Shift Program. The engine has a strong feel in all speeds and gets the A8 from a standstill to 60 mph in 6.6 seconds. The A8 offers two shift positions: Drive and Sport. Downshifts prove quicker with the Sport variant than with the Drive variant, but the Sport option does not allow shifting to sixth gear at highway speeds. Overall, the A8 delivers a refined performance. Maneuverability marks one of the car’s strongest points. The 2005 Audi A8 can handle even seemingly tight curves with ease. Steering feels precise and body roll stays at a minimum even around the tightest corners. The ride quality remains very smooth, giving the driver a feeling of control and confidence that some competitors lack. Despite the controlled handling, the A8 can give quite an adrenaline rush when pushed to the limit.


The 2005 Audi A8 comes with standard safety features, such as anti-lock brakes and 10 airbags, including front and rear side-impact airbags, side curtain airbags, and knee airbags. Government crash tests have not been performed on the 2005 Audi A8.
