GM introduced the new Cadillac STS V at the 2005 Detroit Auto Show, after previously presenting it during a Super Bowl commercial earlier the same year.
Designed as the sportier version of the STS model, the new V Series featured a newly-developed supercharged 4.4 L Northstar V8 unit producing a massive 469 hp and 439 lb/ft of torque. Its main competitors on the European market were the BMW M5 and the Mercedes E55 AMG. It reaches the 0-60 mph in 4.8 seconds and tops the quarter-mile in 13.1 seconds. It received a slight facelift for the 2008 year model and was priced, in the US, at approximately $80,000.
