Full details about the 2017 Cadillac CT6 Plug-In Hybrid are becoming available.
For starters, the powertrain will be a 2.0-liter turbocharged four-cylinder that will pair with two electric motors. The lithium-ion battery pack will have 18.4 kilowatt-hours, just like that of the Chevrolet Volt.
Speaking of the Volt, the CT6 will be borrowing parts from that vehicle and adapting them to the CT6’s rear-wheel drive chassis.
Total system horsepower is expected to be 449, with a 0-62 mph time of 5.6 seconds. Cadillac is also claiming an electric-only range of 37 miles.
The CT6 won’t use the same battery-pack layout as the Volt – instead, the battery will be integrated into the floor, which according to Cadillac, will help increase vehicle stiffness.

Also like the Volt, the CT6 will use a two-motor drive system, but it will add one more planetary gearset (for a total of three) and two more clutches, bringing the total to five.
One of those motors is an induction motor, while the other is a permanent-magnet motor. The latter is based on the electric motor used in the Chevrolet Spark EV, and it will be built at the same Maryland plant where the Spark EV motor is produced.
While that motor will be built in Maryland, and while the battery pack and cells will come from Michigan, the CT6 Plug-In Hybrid will be built only in China. That will make it the first Cadillac ever to be imported to the U.S. for sale when it hits the market as a 2017 model in late 2016 or early 2017.
