The popular Audi A4 continues to offer a very broad line-up. The A4 sedan and wagon (Allroad) are equipped with a 220-horsepower 2.0-litre 4-cylinder turbo. Meanwhile, the sportier S4 comes with a 3.0-litre supercharged V6 that pumps 333 horsepower, as well as a host of improvements designed to enhance the vehicle's handling. There’s even a manual transmission available for those who want it! But no matter which model you choose, all-wheel drive is included.
