Cadillac has divulged the complete details of its flagship CT6 Plug-In Hybrid sedan.
As expected, the hybrid CT6 shares a lot of technology with the Chevy Volt, but its rear-wheel drive setup and sportier personality have necessitated changes as well.
The CT6 Plug-In Hybrid's powertrain consists of a 2.0L turbocharged 4-cylinder gasoline engine, two electric engines and a 18.4 kW/h lithium ion battery pack (that is the same capacity as the Volt's battery pack.) That powertrain works out to a total output of 449 horsepower that can get the CT6 going from 0-62 mph in 5.6 seconds.
For short trips and errands, it should be possible to drive using electric power only. 37 miles of all electric range is all you get, but for many things, that should be enough.
The batteries of the CT6 Plug-In Hybrid are integrated into the floor of the CT6. Cadillac says that this setup increases setup and consequently adds to the sporty feel of the vehicle.
Rather than the T-shape used in the Volt, which places the pack in the tunnel between the front seats and under the rear seats, the CT6 pack is integrated into the floor.
A press release from the CT6 Plug-In Hybrid's unveiling at the 2015 Shanghai Motor Show last year said it was located "between the rear seat and trunk."
The battery-pack tray actually acts as the main floor structure, increasing stiffness, GM's Grewe said.
Grewe continued by saying that the CT6 "gives you a Volt on steroids." Indeed, the CT6 uses a two-motor drive system that is basically the same as the Volt's, except it has a additional planetary gearset (for a total of three) and two more clutches (making five). One motor is an induction motor, while the other is a permanent-magnet design. Grewe says that customers will enjoy the same "EV launch feel" as the Volt, with instant torque from the electric motors used to maximum effect.
This will also be the first Cadillac to be sold in North America that is assembled in China. Expect it to be available late this year or early next.
