Cadillac CT6 PHEV
Green Car Congress recently released a very detailed description of upcoming Cadillac CT6 PHEV and its operation, which will enter U.S. market this year right from China.
The article is partly entitled Chevrolet "Volt on steroids" as CT6 PHEV will offer more fun-to-drive performances from rear-wheel-drive plug-in hybrid drivetrain.
Acceleration 0-62 mph (100 km/h) takes just 5.6 seconds - very fast for a vehicle in this size class, and also as compared to the 8.4 second time to 60 mph for second-gen Volt.
Similar in size 18.4 kWh battery pack will provide more than 60 km (37 miles) of pure electric range, but as you can see on the right - architecture is completely different. Batteries sit in the back along with the charging port; the CT6 PHEV definitely isn't sharing from the Volt as much as Cadillac ELR did.

There is also larger 2.0L turbocharged 4-cylinder direct-injected gasoline engine and two electric motors (one induction and one permanent magnet motor). Drivetrain is extraordinary sophisticated with one more third planetary gearset and two more clutches:
"The new electrically variable rear wheel drive transmission comprises 2 electric motors, 3 planetary gears (two simple, one double-pinion) and 5 clutches that deliver four continuously variable transmission modes with 3 fixed gears."
Just look at the operating modes chart:

Cadillac CT6 Interior (Premium)
- 335 kW (449 hp) combined system power - 198 kW (266 hp) 2.0L turbocharged 4-cylinder direct-injected gasoline engine with a two-motor, 120 kW hybrid transmission.
- 0-100 km/h (62 mph) in 5.6 seconds
- more than 60 km (37 miles) of all-electric range on 18.4 kWh lithium-ion battery
- all-electric top speed of 125 km/h (78 mph)
- combined fuel consumption of less than 2.0 L/100 km (117.7 mpg US)
The standard CT6 starts from $53,495, but the luxury sedan can quickly set one back $68,565 for the Premium Luxury edition, and a full $88,460 for the Platinum version with all the bells and whistles. Hazarding a guess, we imagine the base plug-in version will land somewhere between the Premium Luxury and Platinum Version - around $79,000 perhaps.
