Billed as a luxury 4-door performance sedan, the 2007 Cadillac STS delivers outstanding power and sophistication in a distinctly American package. The STS offers the 254 horsepower, 3.6-liter V-6, or the 320 horsepower 4.6-liter Northstar V-8 engine. Both engines feature variable valve timing (VVT), and are available in rear-and all-wheel drive configurations. New for 2007, the Hydra-Matic 6-speed transmission first introduced on the acclaimed STS-V in 2006, is now standard on AWD and RWD V-8-equipped ’07 models. Coupled to the V-6 is a 5-speed automatic tranny. STS models seat 5-adults in comfort and the trunk can carry 13.8 cubic feet of cargo. For more intense performance, the ‘07 STS-V is fitted with the hand assembled, 469 horsepower, 4.4-liter Supercharged Northstar V-8 paired with the 6-speed automatic transmission. This combination enables 0-to-60 (mph) acceleration in less than 5-seconds.
