The Car Connection's Take
TCC Rating
8.0
8.8
TCC’s Bottom Line
A fuel-stingy new TDI engine and spruced-up appearance make the 2010 Audi A3 a very fuel-efficient, fun-to-drive, and practical compact choice. The 2008 Acura RDX gets its edge from turbo power and crisp handling, but it can feel a little nervous and cramped.
