Road Test

In the sports sedan tug-of-war among Audi, BMW and Mercedes-Benz, the A4 now prevails over its peers. Sports sedans often fall short of expectations, being neither sporty nor luxurious, or prove unreliable. The A4 gets all of these things right, which is why it jumps to the top of this class in our rankings.

Model History

2017-Present

Current Generation

The A4 is among our highest-ranking sports sedan, thanks in part to its satisfying driving experience. Power comes from a 2.0-liter turbocharged four-cylinder, mated to a standard seven-speed dual-clutch automatic. The engine is smooth and punchy, and the transmission is slick. We got a commendable 27 mpg overall. Handling is nimble and precise, the ride is supple, and the A4 feels tight-as-a-drum solid, with a very quiet cabin. The fully digital instrument panel shows pertinent information in front of the driver in a clear, comprehensive way, and the center screen is compatible with Android Auto and Apple CarPlay. Interior fit and finish is excellent and the front seats are comfortable, although the rear seat is tight. The A4 has good crash-test results and offers advanced safety features. The high-performance S4's 3.0-liter supercharged V6 was replaced by a turbo V6 in the 2018 redesign. The wagon version is called the Allroad. A freshening for 2020 brings a different infotainment system, moving from a rotary knob that interacts with a center screen, to a touch screen. 2025 is the final model year for the A4, replaced by the A5.

2009-2016

2009 Redesign Year

The 2009 redesign was a big step forward. Handling is agile and very secure, the ride is firm but supple and interior quality is first-rate. The front-wheel drive version we tested was equipped with an optional continuously variable transmission (CVT) that is smooth and responsive, while optimizing acceleration and fuel economy. All-wheel drive versions use eight-speed automatic transmissions. However, rear seat legroom is still lacking and some of the secondary controls are more complex than they should be. The 2.0-liter four-cylinder and slick eight-speed automatic returned a good 25 mpg overall in our tests. This version of the high performance S4 model is powered by a 3.0-liter supercharged V6.

2002-2008

2002 Redesign Year

The A4 handles nimbly, has a solid feel, and surrounds the driver with impressive interior details. Further, all-wheel drive is an advantage in slippery conditions. However, the car falls short in ride comfort and the rear seat is devoid of legroom. A V8-powered S4 and a convertible arrived for 2004. Midway through 2005, the A4 lineup got a 2.0-liter turbocharged four-cylinder engine, a 3.2-liter V6 and some styling changes.

1996-2001

1996 Redesign Year

This nimble, stylish sports sedan offers a strong and refined 2.8-liter, 190-hp V6, along with a less-refined but responsive 170-hp turbo Four in 1.8T versions. The Four got a 20-hp boost for 2001. Also new are standard side-curtain air bags. The A4's ride is firm yet compliant. The optional five-speed automatic shifts smoothly and allows easy manual shifts. The front seats are very comfortable, though the rear is cramped. Audi's all-wheel-drive Quattro system improves handling and winter traction. The wagon version is called the Avant. The high performance S4 and S4 Avant have a 250-hp twin-turbo engine and firmer suspension.
