As expected, Cadillac announced the addition of a plug-in hybrid (PHEV) powertrain for its range-topping CT6 sedan at the Shanghai Auto Show.
The powertrain combines a 2.0-liter turbocharged four-cylinder gasoline engine with an all-new rear wheel electric variable transmission (EVT) that incorporates two electric motors and draws energy from an 18.4 kWh lithium-ion battery pack positioned between the rear seat and the trunk.
GM estimates the system is capable of producing a combined output of 335 hp (250 kW) and 432 lb-ft (586 Nm) of peak torque, stating that fuel economy will be "more than double that of the car’s conventional engine offerings, as measured by miles per gallon equivalent".
The driver will be able to choose among three operating modes named Normal, Sport and Hold:
• Normal: Designed for everyday commuting. Provides ideal balance of comfort, performance and maximized EV range and fuel economy.
• Sport: Provides more aggressive pedal mapping for improved off-the-line feel and a stiffer steering response.
• Hold: Allows owners to select when the CT6 PHEV uses its engine, reserving the remaining battery charge for later use. This feature helps enhance efficiency because owners who mix city and highway driving can save the battery charge for city travel, where the CT6 EV mode operates most efficiently.
The CT6 PHEV will get GM's Regen on Demand system that allows the driver to temporarily regenerate energy through steering-wheel paddles by slowing the car, such as when entering a turn, much like downshifting with a manual transmission. It also gets iBooster and Electronic Stability Program customized for hybrid electric vehicle regenerative blended braking.
“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 boss Johan de Nysschen. “In the CT6, Cadillac presents a new formula for prestige luxury. The advanced Plug-In Hybrid system is a key addition, providing a combination of exceptional fuel economy, crisp acceleration and strong electric-driving range.”

A new 3-liter V6 will launch with the all-new Cadillac CT6 and be offered in the brand's other sedans, Cadillac announced Friday.
The company detailed the powertrain offerings that will be in their new flagship sedan, set for a March 31 unveiling as part of the New York Auto Show. The CT6 will be one of the first vehicles to show off General Motors' new engine family.
A mainstream offering is expected to be a new, naturally aspirated, 3.6-liter V6 with 335 horsepower and 284 lb.-ft. of torque. That's up from 14 horsepower from the 3.6 V6 currently offered in the ATS and CTS.
But in keeping with modern turbocharging trends, a new 3.0-liter twin-turbo V6 with 400 horsepower and 400 lb-ft torques will also be introduced. In addition to revised mechanicals for greater efficiency, these new engines also sport cylinder deactivation and start/stop. Cadillac says it expects a 9-percent fuel economy bump from this engine over the outgoing 3.6 that's in a whole bunch of GM products.
Those two Cadillac sedans will also get the new 3.6-liter engine, although the 3.0-liter turbo is for now reserved for the CT6. An 8-speed automatic will be the transmission for these engines, doing away with the six-speed unit that's been offered on the outgoing engine.
“Cadillac’s elevation on the world stage is driven in great part by its advanced powertrain technology and the all-new 3.0L Twin Turbo powers past the traditional segment leaders with higher degrees of the performance and refinement their reputations were built on,” said Rich Bartlett, assistant chief engineer.
“Torque is the pulling power of an engine and the new 3.0L Twin Turbo delivers it with confidence-inspiring smoothness and progression,” said Bartlett. “In fact, the potency of the torque across the rpm band is matched only by the satisfaction of the horsepower created as those revs climb quickly to 6,500 rpm.”
Cadillac officials confirmed engine details CEO Johan de Nysschen let slip last month, including that the CT6 would also offer a turbocharged four, which is probably going to be the 2.0-liter, 270-horse unit in the ATS and CTS. It might not be a slouch, given the CT6 is all about lightness in its construction.
