TCC’s Bottom Line

The 2010 Acura RL offers lots of features and strong safety. Performance takes a backseat in the 2010 RL-but technology and durability certainly don't.

The 2010 Cadillac STS drives well-the STS-V is a trailblazer-but the cramped backseat and well-worn styling haven't kept pace in the luxury class.

TCC Likes

Big, silky V-6
Solid ride quality
Comfy seats

Magnetic Ride Control's ride and handling
V-6 is powerful and saves fuel
Top-notch performance from the STS-V

TCC Dislikes

Lack of V-8 engine, rear-wheel drive
Five-speed transmission
Busy front-end styling, bland body

Plain, unadorned dash
Some lower-budget interior finishes
Backseats aren't large enough
