For a 4-door that packs a lot of excitement, there's our Best Sport Sedan winner, the Cadillac CTS. Upping the ante against BMW and Mercedes, the totally redesigned 2008 Cadillac CTS offers enthusiast drivers two sophisticated V6 engines, available all-wheel-drive, three different suspension packages, and a luxurious, superbly equipped cabin; all wrapped up in Cadillac's most muscular styling to date. It's an American-brand sport sedan capable of sharing the most demanding roads in the world.
