A Brief History of the 2009 Cadillac STS

The origins of the STS were from the Cadillac Seville, which was dropped in 2004. STS stood for “Seville Touring Sedan” and was originally a performance package for the Seville. Size-wise it fits between the Cadillac CTS and full-size DTS. The STS was rear-wheel drive based on the Sigma GM corporate platform. An STS-V performance variant was produced from 2006-2009, featuring a 4.4-Liter Northstar V8. The 3.6-Liter LY7 V6 was standard. The first generation ran from 2005-2007. The 2008 STS marked the new design still based off of the Sigma platform. Cadillac also assembled the STS in Shanghai, China, called SLS from 2007-2013. A larger CTS introduced in 2014 succeeded the STS.

2009 STS

A new “Platinum” model was introduced with special interior and exterior additions including 18-inch alloy wheels. Lane departure and side blind zone alert systems were also available.
