When Cadillac introduced its all-new CT6 sedan at the New York Auto Show several weeks ago, it detailed 265-hp four-cylinder turbo and 400-hp twin-turbo V6 engine options. At the Shanghai auto show last week, it announced another powertrain option: a 335-hp plug-in hybrid powertrain set to double the fuel economy over the ICE alternatives.

One of the big selling points of the CT6 is that its lightweight Omega architecture gives it the size and spaciousness of a true luxury flagship, but the weight of a smaller car. Those weight savings make it ripe for an alternative powertrain. GM's solution uses a dual-motor, rear-mounted electric variable transmission (EVT) system, an 18.4-kWh lithium-ion battery pack between the trunk and rear seats, and a 2.0-liter turbocharged four-cylinder. The system puts out a total of 335 hp (250 kW) and 432 lb-ft (586 Nm) of torque.

"The first-ever CT6 is a technological showcase throughout, making it an ideal platform for Cadillac to offer its first plug-in hybrid,” said Cadillac president Johan de Nysschen. "The advanced Plug-In Hybrid system is a key addition, providing a combination of exceptional fuel economy, crisp acceleration and strong electric-driving range."

Cadillac is holding off on estimating the all-electric range, but it did say that it will be enough for "most daily commutes," which sounds similar to the "80 percent of Americans driving fewer than 40 miles each day" that GM was using back at Chevy Volt launch time, although it was in Shanghai this time around. We expect to see an all-electric range in that 40-mile (64-km) ballpark, and reports from sources like Automotive News put the number at 37 miles (60 km). Cadillac also expects the plug-in system to offer more than double the fuel economy of the CT6's gas powertrains, as measured in mpg-e.

GM promises that the two rear motors will deliver "smooth, spirited acceleration." The CT6 PHEV will run in three different driving modes: Normal, the everyday commuter mode designed to blend comfort, performance and fuel economy; Sport, with more aggressive pedal mapping and stiffer steering response; and Hold, which reserves battery power for later use. The car will also feature Cadillac's paddle-shift Regen On Demand feature, also used in the ELR and new Chevy Volt, along with traditional regenerative braking.

GM will begin production of the standard CT6 later this year, with the PHEV expected to follow in 2016. Pricing has yet to be released.

I knew the ELR was a rough start for them but man that's cold.
Also, like the CT6 the 2016 Chevy Volt also has a 18.4 kWh battery. There are other differences but the new Volt is expected to hit ~50 miles on EV.
The 2015 Volt that used the 17.1 kWh battery was rated at 38 miles and the ELR that shared the same platform was rated at 35 miles on EV (because of slightly increased power). That doesn't tell us the EV range of the CT6 but it's probably enough to make a decent guess.
Cadillac will produce a 2016 ELR (and maybe a 2017) but the car only sells 100 units/month and Johan said they are not planning a successor for it (but doesn't want to say they are killing it off). They will instead incorporate PHEV systems into other models in their lineup which appears to be the case here.

It's amazing, most of the videos and articles online, just about all of them, having to do with the Cadillac CT6 DO NOT mention the plug-in hybrid drivetrain option, so a lot of people have no clue this wonderful drivetrain is available for this car.
