Benefits of Driving a 2011 Cadillac STS Sedan

The STS boasts strong, smooth performance with the direct-injected V6, so the V8 won't truly be missed. Although many of its most innovative tech features have been discontinued, several standout features and options remain available on the STS, including Intellibeam headlamps, the head-up display, and blind-spot and lane-departure systems. Considering those features, along with the STS's robust roster of airbags and excellent handling, it's a very safe luxury sedan.

What's new for 2011?

The 320-hp, 4.6-liter V8 has now been discontinued, as has the all-wheel drive option. And with the V8 goes adaptive steering, adaptive damping, Magnetic Ride Control, and 4-wheel active steering--all features that were offered only on the former top model. The high-performance STS-V model of previous years has also been discontinued.

Model Strengths

  • Strong overall performance
  • safety and stability
  • standout tech options
  • smooth ride
  • quiet cabin

Model Review

The rear-wheel-drive STS is now available only with a direct-injected, 3.6-liter DOHC V6 engine, making 302 horsepower and 272 pound-feet of torque. A very smooth-shifting, responsive 6-speed automatic transmission is standard, and it includes both a low first gear for strong takeoffs and a tall top gear for relaxed, economical cruising. The STS has an EPA-estimated 18 mpg city, 27 mpg highway.
