For 2011, the STS is no longer available with the Northstar V8 engine, leaving the 3.6-liter V6 as the sole power plant. All 2011 STS models are now covered by Cadillac's Premium Care Maintenance program.
2008 Cadillac STS V6 receives a new 302-horsepower, 3.6-liter engine. New options for the STS V6 include a performance package, HID headlights and the Head-Up Display (HUD). Refreshed exterior styling is enhanced by some new technological features such as Lane Departure Warning and Side Blind Zone Alert.
Once hailed as the savior of the Cadillac brand, the STS luxury sedan now seems to be overshadowed by the brilliant CTS
Wagon, not to mention the impressive V-Series cars. Still, for those looking for luxury without hair-raising performance, the STS remains a crowd pleaser. Along with its slightly larger cousin, the DTS, the STS' mission is to continue satisfying the aging Cadillac faithful while still appealing to younger, first time buyers. Although it is available with all-wheel drive and a performance package suspension upgrade, the loss of the Northstar V8 engine this year will probably also cost the STS some potential buyers.
