2025 Audi S4

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.

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.
