Review and specifications
2021 Audi A4
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.

Brand context
About Audi
Audi sells a wide range of sedans and SUVs with luxurious interiors and lots of technology. Several of its SUVs and sedans have earned CR’s recommendation for balancing driver and passenger comfort with smooth power and nimble handling. In most cases, buyers shopping for sedans and SUVs in the luxury category should consider Audi’s options. Fit and finish quality reaches even the lowest-priced models. However, like most luxury cars from European brands, maintenance and repair costs can be expensive, making used Audis difficult to recommend. Typically, Audi identifies sedans with the letter A, SUVs with the letter Q, and numbers that increase according to size. The Q3 is a compact crossover while the Q8 is a three-row SUV. Models that start with S or RS are tuned for performance and have more power, stiffer suspension, and more aerodynamic exterior details. All-electric models have the E-tron suffix.
