Base MSRP $42,200

The 2013 Audi A6 is a mid-size luxury sport sedan that offers strong performance while also delivering all-weather confidence and good gas mileage. Interior and back-seat space is also a bit better than in other rear-wheel-drive European sport sedans, and the interior appointments themselves stand out as more fashion-forward. Audi claims best-in-class fuel economy for the 2.0T model, which achieves up to 24 mpg city, 33 highway. Advanced technology--whether for safety, information, or entertainment--is where the A6 really stands out. It offers blind-spot monitors, a night vision system, a head-up display, parking sensors, adaptive cruise control, and other leading-edge safety features, but it's also ahead of the curve with its excellent MMI Touch system, which includes a simplified interface and a scratch-pad controller that lets you input addresses by tracing individual letters. Meanwhile, the S6 remains a performance standout--this time with improved mileage, yet with stronger performance than ever. The new model can get to 60 mph in just 4.8 seconds.
