At the top of the range, a twin-turbo 3.6-liter V6 good for 420 hp and 430 lb-ft of torque will be available. A naturally aspirated version of that 3.6L V6 engine rated at 321 hp will also be available, as well as a 2.0-liter turbocharged engine rated at an estimated 272 horsepower.
The turbo and naturally aspirated V6 engine will be mated exclusively to an eight-speed transmission, complete with paddle shifters, while the 2.0-liter turbo will be linked up to a six-speed auto. The twin-turbo, eight-speed combo will hustle the CTS to 60 mph in about 4.6 seconds, and return an estimated fuel economy rating of 17/25 mpg city/highway.
Cadillac’s largest sedan, the XTS, will also be fitted with the twin-turbo V6 starting this fall. In that application, the engine will put out 410 hp and 370 ft-lb of torque.
