About the Cadillac STS

The lone Cadillac with the palindrome for a model name got its start in 2005 as the successor to the Seville.  This luxury sedan has 4 doors and seats 5.  In addition, the STS has always offered a V6 and V8 powertrain.

Like any good stock portfolio, the Cadillac STS emphasizes diversification.  Trims have expanded from a simple V6 and V8 in '05 to increasing variations on both powertrains as well as the stronger STS-V.  

As of 2007, the STS offers 3.6 L, 255 hp V6 and 4.6 L, 320 hp V8 powertrains.  Expect exterior changes and other adjustments for 2008 and beyond.
