Cadillac's performance sedan enters 2008 with new power, styling, and technology. The base STS receives a new 3.6L direct injection V6 engine, which boasts 302 horsepower and 272 lb-ft of torque. A six-speed automatic transmission completes the powertrain. Other revisions for this year include the new optional active steering feature, GM's Lane Departure Warning System, restyled grille and moldings, and newly available 14-spoke aluminum wheels. Available options on the STS include a power glass moonroof, leather seats, performance brakes, and several trim option packages.
