Cadillac STS Review

The 2010 Cadillac STS defies the stereotype of a huge Caddy sedan that handles ponderously, where the back seat is the place to be. The STS offers handling that defies its huge size, athletic poise thanks to its magnetic ride control, and a bold look. The "Cadillac STS" is the driver's car.
But the Cadillac STS has suffered quality problems, with many reviewers citing questionable interior build quality.

The base Cadillac STS features a direct-injected 3.6-liter V6 rated at 302 horsepower and 272 pound-feet of torque. A full-size luxury sedan in its physical dimensions, the Cadillac STS is priced in line with other premium midsize sedans that offer V6 and V8 engines. There are five trim levels -- V6 Luxury Sport, V6 Luxury, V6 Premium, V8 Luxury and V8 Performance. The V6 Luxury adds perks such as Bluetooth, heated/ventilated front seats, heated rear seats and rain-sensing wipers. The V6 Premium highlights include 18-inch (versus 17-inch) wheels, upgraded braking/steering/cooling systems, auto-dimming xenon headlights, upgraded audio and a navigation system. In reviews and road tests, our editors have found the strengths of the Cadillac STS to be its nimble road manners, powerful engine options and high-quality audio system.

The Cadillac STS rear-wheel-drive luxury sport sedan officially debuted for the 2005 model year and offered in 255-hp V6 and 320-hp V8 versions. Prior to 2010, the current STS's trim levels were essentially option packages available on V6 and V8 trims.

The performance-oriented version of that car was known as the Cadillac STS and featured a more powerful V8 engine and more luxury features. The 1992-'97 Seville also featured a similar STS edition.
