Unchanged for 2009, the five-passenger Cadillac STS-V is a large high-performance luxury sedan available in one trim level that comes fully loaded. As the most powerful expression of Cadillac STS power and luxury, Cadillac STS-V performance is due to a supercharged 4.4L V8 engine pumping out 469 hp and 439 lb-ft of torque paired with a six-speed electronically controlled automatic transmission with driver shift control. The rear-wheel drive sedan can sprint from zero to 60 mph in 5.1 seconds. Inside, STS-V luxury is highlighted by special leather-trimmed upholstery and premium wood trim accents. Standard safety features include antilock disc brakes, stability and traction control, front seat side airbags, full-length head curtain airbags, OnStar and a rearview camera, as well as blind-spot and lane-departure warning systems. EPA-estimated fuel economy achieves 13 mpg city/19 mpg hwy.
