Cadillac CT6 Plug-in Hybrid Makes 335 Horsepower, Doubles Fuel Economy
By Jeff Youngs,
Cadillac has announced that its new flagship luxury sport sedan, the 2016 CT6, will be offered with a plug-in hybrid powertrain that doubles the car's fuel economy while producing 335 horsepower. During the unveiling of the car at the 2015 Shanghai International Auto Show, Cadillac President Johan DeNysschen promised "a combination of exceptional fuel economy, crisp acceleration, and strong electric-driving range."
The Cadillac CT6 Plug-in Hybrid (PHEV) features a turbocharged, direct-injection, 2.0-liter 4-cylinder engine with variable valve timing, 2-motor electric variable transmission (EVT) driving the car's rear wheels, and an 18.4-kWh Lithium-ion battery pack housed between the rear seat and the trunk. Combined output is estimated to be 335 horsepower and 432 lb.-ft. of torque, and the CT6 PHEV is equipped with fuel-saving automatic start/stop technology.
Three driver-selected operation modes include Normal, Sport, and Hold. The Normal driving mode maximizes electric-only operating range and fuel economy when the CT6 PHEV's gasoline engine is running. Sport driving mode makes the car feel livelier and adjusts steering feel for added stiffness, according to Cadillac. Hold driving mode allows the car's owner to conserve electric-only operation for those times when it is more advantageous to use, such as in the city rather than on the highway.
According to Cadillac, the CT6 PHEV is compatible with 120- and 240-volt chargers, and is designed to provide "all-electric driving for most daily commutes." Official electric range estimates will be revealed closer to the car's arrival in U.S. showrooms.
Regenerative brakes with iBooster technology maximize the capture of the kinetic energy that would otherwise be lost during braking, converting it into electricity that is stored in the car's battery pack. Cadillac will also include Regen-on-Demand technology, activated using paddle shifters on the CT6 PHEV's steering wheel. Regen-on-Demand feels similar to a transmission downshift and is useful when driving the car in an enthusiastic fashion, such as when preparing to enter a corner, Cadillac says.
Additional details about the new Cadillac CT6 Plug-in Hybrid will be available closer to the car's arrival in showrooms.
