Cadillac STS Parts & Accessories

Though it has grown into an entirely different species, the luxury performance DNA of the Cadillac STS can be traced all the way back to the special range-topping Seville hardtop coupe of the 1950s. At that time one of the fastest, flashiest and most luxurious cars on the road, it evolved and re-emerged several decades later as the buttoned-down Seville luxury sedan, capable of sharing company with Europe's finest. Evolution gave way to revolution in 2005 as Cadillac dropped the Seville moniker in favor of its alpha-centric naming strategy, coinciding with a quantum leap forward in technology, build quality and overall refinement. Based on GM's global Sigma rear- and all-wheel-drive platform and utilizing powerful new V6 and Northstar V8 engines, the Cadillac STS is once again capable of taking on all comers. The two available engines -- a surprisingly responsive 3.6-liter V6 rated at 255 horsepower and 252 lb-ft of torque, and a 4.6-liter Northstar V8 that generates 320 hp and 315 lb-ft of torque -- both feature variable valve timing and electronic throttle control. A five-speed automatic transfers power from the V6, and a six-speed automatic helps V8-equipped STSs achieve impressive acceleration and fuel economy for this class.If you're in the market for a finely tailored luxury sedan with the power, roominess, comfort and value to outpace many of its smaller German and Japanese rivals, we recommend that you take a serious look at the Cadillac STS. Common features on all models include leather seating, 17-inch wheels, dual-zone climate control, a Bose sound system and OnStar. Popular options include a navigation system, a head-up display and heated/ventilated front seats grouped in two available Performance and Luxury trim packages.
