The 2008 Cadillac STS wraps up luxury and fuel efficiency in a beautiful package. Like the slightly smaller CTS, the STS produces very good gas mileage ratings for a mid-size luxury sedan equipped with an all wheel drive (AWD) system. (Rear wheel drive is standard.) While the STS is slightly longer and heavier than the CTS, its interior dimensions are very close to its less expensive brother. All-in-all, the STS represents an excellent opportunity for Cadillac to retain Escalade owners looking to downsize, but stay with the brand as the move to a more appropriate AWD vehicle for today’s climate.
Standard 2008 Cadillac STS power train choices include a 3.6 liter V-6 producing 302 horsepower (HP) / 272 foot pounds of torque and a 4.6 liter V-8 that delivers 320 HP / 315 foot pounds of torque. The STS-V is fitted with a 4.4 liter V-8 producing 469 HP /439 foot pounds of torque. A six-speed Hydra-Matic automatic transmission is standard.
