In 2008, the Audi A4 offered multiple engines depending on market and trim. The U.S. lineup was centered around a 2.0-liter turbocharged inline-4 and a 3.2-liter V6, while European models commonly included diesel options in addition to gasoline variants.
United States — core gasoline options
For the American market, the primary gasoline engines were:
- 2.0-liter turbocharged inline-4 (2.0T FSI/TFSI) — about 200 horsepower, with torque that emphasizes urban acceleration; available with front-wheel drive or quattro all-wheel drive.
- 3.2-liter V6 FSI — about 255 horsepower, typically paired with quattro and an automatic transmission.
Note: Availability could vary by trim level and transmission choice. Diesel engines were not offered in the U.S. 2008 A4 lineup.
Europe and other markets — broader engine options
Outside the United States, Audi offered a wider range of engines on the 2008 A4, including diesel variants and additional gasoline options. Typical configurations included:
- 2.0-liter TDI — diesel option with outputs typically in the 140–170 horsepower range, favored for efficiency.
- 3.0-liter TDI V6 — more powerful diesel choice for higher-end trims.
- 2.0-liter TFSI — gasoline turbocharged four-cylinder similar to the U.S. engine but tuned for European markets.
- 3.2-liter V6 FSI — gasoline option delivering about 255 horsepower, widely available across regions.
Across markets, the 2008 A4’s engine lineup ranged from efficient diesels to punchy gasoline engines, with the 2.0-liter turbo four and the 3.2-liter V6 serving as the primary gasoline choices in many regions.
How to verify the exact engine in a specific car
Because engine availability varied by country, trim, and model year, the best way to confirm the exact engine on a given 2008 A4 is to check the vehicle identification number (VIN) and the original window sticker, or consult the owner's manual and factory documentation for that car.
Summary
The 2008 Audi A4 did not use a single engine. In the U.S., buyers mainly chose between a 2.0-liter turbocharged four and a 3.2-liter V6; in Europe and other markets, diesel options such as the 2.0 TDI and 3.0 TDI complemented the gasoline 2.0 TFSI and 3.2 FSI variants. Always verify the exact engine on a specific vehicle via its VIN or official documentation.
