OEM Cadillac STS Parts and Accessories

The Cadillac STS is a midsize luxury sedan marketed by GM’s Cadillac division from the 2005 through 2011 model years. It succeeded the iconic Cadillac Seville, and also carries its name in the STS acronym that stands for “Seville Touring Sedan”. During its launch, it was offered only in rear-wheel drive (RWD) and featured a 4.6-liter V8 engine that produces 320 hp and 315 pound-feet of torque.

In 2012, the STS was replaced by the bigger Cadillac XTS. The 2011 Cadillac STS was the last of its kind and was available both in RWD and AWD. Trim options included the base, Luxury, and Premium. The V8 engine was dropped, with the STS being powered by a 302-hp V6 engine instead. For superior performance, the limited-edition Cadillac STS-V was offered until 2009 and came with a muscular 4.4-liter V8 that peaked at 469 hp and 439 pound-feet of torque.
