Cadillac's midsize sport sedan, the STS, features a powerful base engine, an optional V-8 and a variety of high-tech safety options. The STS competes with the BMW 5 Series, Lincoln MKS and Hyundai Genesis.
New for 2010
The 469-horsepower STS-V has been discontinued.
The STS' bumper is prominent, and its grille is dominant. Like it or not, you have to admit that the elements are in proportion, from the plunging grille to the stacked headlights and fog lights. A Platinum Edition Package, optional with either engine, adds a new grille finish and 18-inch chrome wheels.
- Rocker-panel moldings
- Small spoiler
- Chrome door handles
- Polished-aluminum dual exhaust tips
- Standard 17-inch alloy wheels, optional 18-inch alloys
The STS can have optional wood trim; real metal trim accents the steering wheel and dashboard. The Platinum Edition augments the cabin with a leather dashboard and a suede-like ceiling.
- Optional head-up display projects vehicle speed and other selectable readouts on the windshield
- Optional adaptive cruise control and remote-start systems
- Standard eight-speaker Bose stereo
- Optional 15-speaker, Bose 5.1-channel surround-sound stereo
- Standard leather seats, dual-zone climate control
