Cadillac's STS is nearly the same size as the CTS, but the STS is aimed at a different class of vehicles. STS's aspirations of becoming a world-class vehicle are backed up by a healthy list of electronics such as 5.1 surrround sound, DVD navigation, active cruise control and stability control. A V6 coupled to a 6-speed automatic is standard on all models. Both RWD and AWD configurations are available. Starting in the upper 40s, the STS can get pricey with some models topping $60k.

What Changed:

The V8 model has been dropped for 2011. A 3.6l V6 is the only available engine.
