The lineup expands with the addition of a V-6-powered all-wheel-drive variant at the low end and a high-performance STS-V model at the top of the price spectrum. In addition to a revised suspension, higher-rated wheels and tires, the rear-drive “V” edition comes with a supercharged 4.4L V-8 that produces 469 hp and 439 lb.-ft. (595 Nm) of torque compared with 320 hp and 315 lb.-ft. (439 Nm) of torque for the 4.6L V-8 used in lesser models. The high-output engine is mated with a new 6-speed automatic transmission. A unique grille and other exterior trim also help differentiate the STS-V. All variants also come with a 12-month subscription to the OnStar-supplied Cadillac Personal Advisor service that includes hands-free calling, 3-day weather forecasts, traffic conditions along three personalized routes and information on up to 10 selected stocks trading in the U.S.
