Detroit, Michigan – The upcoming 2006 Cadillac STS-V has completed testing and is certified at 469 horsepower, significantly more than the estimated 440 when the car debuted earlier this year. The car was tested at Germany’s Nurubrgring test track, where it clocked lap times of approximately 8:30.

Production is scheduled to begin in the fall; the STS-V features a new 4.4-litre supercharged Northstar V8 engine and GM’s new Hydra-Matic six-speed automatic transmission. It is the highest output ever for a production Cadillac. The supercharged engine will also be used in the upcoming XLR-V roadster, slated for production in early 2006. Due to its power-to-weight ratio, it is expected to be even quicker than the STS-V.
