The Audi A4 competes with top sport sedans from Germany, Japan, and the U.S., including the BMW 3-Series, Mercedes-Benz C-Class, Cadillac ATS and INFINITI G37, as well as the Acura TL. Among these models, the A4 offers one of the best compromises between comfort and performance, as well as exterior and interior designs that are superbly coordinated. With its 2.0T engine, the A4 is also one of the most fuel-efficient models in its class, while the S4 offers one of the highest power outputs, excluding track-focused models.
In-dash technology, connectivity and infotainment is also a strength of the A4 and S4 family. While Audi Connect made its debut in Audi's larger models, the A4 gets the most advanced new form of the system, with Google Maps data and one of the clearest mapping displays.
