The 2014 Audi A6 is a mid-size luxury sedan known for its elegant styling, comfortable ride, and advanced technology. Engine options for the 2014 A6 include a 2.0L turbocharged inline-4 (220 hp, 258 lb-ft of torque), a 3.0L supercharged V6 (310 hp, 325 lb-ft of torque), and a high-performance 4.0L twin-turbo V8 in the S6 (420 hp, 406 lb-ft of torque). Available transmissions are an 8-speed automatic and a continuously variable transmission (CVT) with the 2.0T front-wheel-drive configuration. Owners typically appreciate the A6’s refined interior, smooth handling, and user-friendly infotainment system. Common dislikes often include the cost of maintenance and repairs, some reported reliability issues, and the somewhat detached driving experience compared to sportier rivals.
