When the Cadillac CT6 hits showrooms later this year, power for the flagship will come in the form of two V6 engines.
The mills are a 3.6-liter naturally aspirated unit, and a 3-liter twin-turbo. Both engines are equipped with active fuel management and start-stop, helping to improve fuel economy when compared to the engines they will replace in other Cadillac products.
Power figures for the 3.6-liter come to 335 horsepower and 284 lb-ft of torque, while the twin-turbo engine pumps out 400 horses and 400 lb-ft of torque. Both V6s will be paired with versions of General Motors’ Hydra-Matic eight-speed auto: the 8L90 for the turbocharged unit, the 8L45 for the naturally aspirated engine.
Both engines use aluminum blocks with more structuring in the bulkhead for increased rigidity; forged-steel crankshafts; polymer-coated, high-copper-content cylinder heads; cushioned chain sprockets for greater noise reduction; and a new two-pump oiling system for greater fuel efficiency and quieter operation.
Both V6s will be produced at GM’s Romulus Powertrain Operations in Romulus, Mich. — thanks to a $540-million investment to build the new engines — and will be placed under the bonnet of CT6 prior to delivery, which is set to begin between October and December of 2015.
