SHANGHAI -- Cadillac introduced a plug-in hybrid version of its CT6 large sedan that will travel an estimated 37 miles or more on electric power before switching into gasoline mode for additional range.
The extended-range concept is similar to that of General Motors' Chevrolet Volt, although the drivetrain is different.
The CT6 will use two electric motors and an 18.4 kilowatt-hour lithium ion battery pack, along with a 2.0-liter turbo engine. The system will provide all-electric driving "for most daily commutes," General Motors said, but blend power from the engine and battery under more demanding driving conditions.
The plug-in hybrid model will produce an estimated 335 horsepower and 432 pounds-feet of torque. U.S. sales likely will start in the first half of 2016, after the rollout of the non-hybrid CT6, which goes into production in the U.S. in December.
"This is an EV without any of the disadvantages or range constraints," Cadillac President Johan de Nysschen told hundreds of attendees at an event Sunday night on the eve of the start of the auto show here. He spoke at a new Cadillac assembly plant.
De Nysschen said the car will be able to go farther than 60 kilometers, or 37 miles, on electric power alone.
