DETROIT — An all-new 3.0-liter twin-turbocharged V6 engine will be one of the powertrain options available to buyers of the 2016 Cadillac CT6 flagship sedan, GM announced late last week. The new CT6 debuts on March 31 at the 2015 New York Auto Show.
Production of the CT6 begins later this year.
The new V6 is estimated to deliver 400 horsepower and 400 pound-feet of torque. GM is calling it "one of the industry's most advanced six-cylinder gasoline engines."
The engine, which features fuel-saving cylinder deactivation and stop-start functionality, is linked to an eight-speed automatic transmission. The combination is expected to enhance fuel economy, making the CT6 more competitive against the Audi A8, BMW 7 Series and Hyundai Equus.
In comparison, the 3.0-liter inline six-cylinder engine in the 7 Series delivers 315 hp and 330 lb-ft of torque. The A8's supercharged 3.0-liter V6 engine churns out 333 hp and 325 lb-ft of torque. The Equus does not offer a V6 engine choice.
The EPA has not announced fuel economy numbers on the CT6.
Other CT6 engine choices will include Cadillac's naturally aspirated 3.6-liter V6 engine and the 2.0-liter turbocharged four-cylinder engine shared with the Cadillac CTS sedan.
Edmunds says: The pieces of the puzzle are slowly coming together on the new Cadillac CT6. Consumers putting together their end-of-the-year shopping lists now have some critical information to consider.
