Now in its sixth generation, the Volkswagen Golf is all-new for 2010. The popular hatchback packs a load of standard features in a pleasing cabin, and despite its small size, the Golf is able to swallow passengers with ease and, with the rear seats folded flat, lots of gear. The TDI offers an impressive EPA estimated 30 mpg in the city, 42 mpg on the highway, while the GTI-the original "hot hatch"-is propelled by its turbocharged four from 0 to 60 mph in less than seven seconds.
