Once offered in multiple body styles, the 2010 Audi S4 is available to U.S. consumers in sedan guise only. Mechanical upgrades include a new supercharged 3.0-liter V6 engine, an available seven-speed dual-clutch automatic transmission and a Sport Rear Differential system tied to standard quattro all-wheel drive.
For 2014, the Audi A4 and S4 line continues among the leaders of entry-luxury sports sedans. Inside and out, it's beautifully styled and built with exquisite attention to the details, and offers generous space efficiency with an extraordinarily high level of interior refinement. The A4 engines are powerful, comfort is supreme, performance is impressive, and efficiency is noteworthy – the entire package is terrific. The S4, with its supercharged V6 and quattro all-wheel-drive (AWD) setup, resides in the nation of awesome. In a tough class with the BMW 3 Series, Mercedes-Benz C-Class, Cadillac CTS and Infiniti G37 (renamed the Q50 for 2014), among others, the beautiful and beautifully-detailed A4 remains a formidable and highly-attractive choice.
