2006 Cadillac STS V Front

Cadillac built its second legit sedan using the same architecture of the first (the CTS). This enlightened version of what used to be the Seville now sends all that 255 HP V6 or 320 HP Northstar V8 torque through the back end instead of the front, and unlike its competitors, Cadillac wisely paired the optional all-wheel-drive with the more powerful engine.
