CR's Take

This high-performance version of the A4 uses a smooth 4.2-liter V8 engine that drives all four wheels. A six-speed manual transmission is standard; a six-speed automatic optional. In our tests we found the ride stiff but not punishing, unlike other sports cars. Handling is quite capable, but the S4 understeers a bit too much at its limits. Audi says it is adjusting the way power is delivered to the front and rear wheels to reduce this. The interior is well-finished and nicely appointed. The leather racing-style seats are supportive and comfortable. The RS4 is a limited-production version with even greater performance levels.

Model History

2018-2025

2018 Redesign Year

The 2018 redesigned S4 is now based on the new A4 platform. This high-performance AWD sedan is powered by a 354-hp, 3.0-liter turbo V6 mated to an eight-speed automatic, the same powertrain that is on the 2018 S5. Advanced safety and infotainment systems are all up to date.

2010-2017

2010 Redesign Year

The S4 is a high-performance version of the small Audi A4. It used a version of the A4's engine and either a six-speed manual or automatic transmission. All-wheel drive was standard. Acceleration is terrific, but handling isn't that much better than the regular A4, and the ride is somewhat stiff. The interior is cramped, especially in the rear seat.

2005-2009

2005 Redesign Year

The S4 is a high-performance version of the small Audi A4. Introduced in 2000, In 2004, a new S4 offered a 340-hp V8 engine along with a six-speed manual or six-speed automatic transmission. Acceleration is terrific, but handling isn't that much better than the regular A4, and the ride is somewhat stiff. The interior is cramped, especially in the rear seat.
