2010 Cadillac STS Overview

With two powerful engine options and a blend of luxury and sports-oriented engineering in a large sedan, the 2010 Cadillac STS plays both the smooth cruiser and a fun-to-drive four-door.

Starting off the powertrain lineup is a 302-horsepower, 3.6-liter V-6 with direct injection technology. Also available is a 320-horsepower, 4.6-liter V-8. Both engines are mated to a six-speed automatic transmission with available all-wheel drive. Powertrain calibrations were engineered to enhance both fun driving and fuel-efficient operation; as a result, fuel economy is 15-18 mpg in the city and 22-27 mpg on the highway. V-6 power is excellent, and fuel economy is on par with the Mercedes-Benz E-Class, Audi A6 and BMW 5-Series.

The 2010 Cadillac STS boast more leg and shoulder room than the E-Class and 5-Series. The Luxury model comes with heated leather seats, dual zone climate control, aluminum trim throughout the interior, an 8-speaker Bose stereo with XM Satellite Radio and OnStar satellite communications.  A 15-speaker stereo, sunroof, wood and leather interior trim packages and Bluetooth connectivity are optional.

The Luxury Sport model is nearly as well equipped, while the Premium model includes great standard features such as a TV with video game connectivity, navigation system and the fifteen-speaker Bose stereo. The Performance Handling Package enhances the driving experience with active steering, magnetic-fluid shocks with pneumatic load leveling, beefed up brakes, bigger 18-inch wheels and high-performance tires.

Under the beautiful STS skin is a chassis designed not only for fun driving dynamics but also crash-worthiness. Hidden away in the interior are dual front, front-side and two-row head airbags to make a great crash-worthy package. The 2010 Cadillac STS achieves Four-Star front and side impact ratings from NHTSA, except for a Five-Star rear passenger side-impact rating. To prevent accidents, standard/available features such as antilock brakes, a lane departure warning system, adaptive cruise control, traction control and stability control are provided to keep the STS under the driver’s command.

Raw power, performance-oriented suspension, luxurious trimmings and plenty of room combine under an edgy and beautiful body to create the highly desirable 2010 Cadillac STS sedan.
