2010 Audi S5

With the addition of Cabriolet models for 2010, Audi has a full line of coupes and convertibles ranging from fuel-efficient turbo 4-cylinder to powerful V8 and turbo V6 models. The A5 and S5 coupes hit the target on design and styling--they're quite possibly the best-looking 2-door touring cars inside and out. Interior comfort and ride quality is also top notch, with the coupe making an especially good long-distance cruiser for two. Also, Audi says that the A5 and S5 Cabriolet models have best-in-class trunk space.
