We were told to expect the 2016 Cadillac CT6 plug-in variant in Shanghai, and it seems Mark Reuss is a man of his word. The 2016 Cadillac CT6 PHEV debuted today at Auto Shanghai 2015 and introduced a slew of new plug-in technologies, including a slick electric variable transmission.
Cadillac is quick to point out the 2016 CT6 PHEV will offer double the fuel economy of the car’s conventional powertrains. The PHEV takes advantage of the already versatile Omega platform, and gears it to go green. Cadillac expects the all-electric range to be suitable for most daily commutes, but a blend of engine and battery power will maximize fuel efficiency at higher speeds, and larger loads.
“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. “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.”
Providing the shock therapy to the 2016 CT6 PHEV’s fuel efficiency is a 18.4 kWh lithium-ion battery pack, located between the rear seats and the trunk. The battery uses the latest in cell chemistry, and is found on other new PHEV products from General Motors. Charging can be completed through either a 120V or 240V charger.
The biggest news complimenting the lithium-ion battery is the addition of a Cadillac-developed electric variable transmission, or EVT. The EVT is a two-motor rear-wheel system working in harmony with the 2016 CT6 PHEV’s 2.0-liter turbo four-cylinder and the battery. Cadillac says the entire system is capable of producing 335 hp and 432 lb-ft of torque, while marrying smooth power delivery at all times.
“The CT6 PHEV will deliver exceptional smooth, responsive acceleration that Cadillac and luxury sedan owners demand,” said Travis Hester, Cadillac CT6 executive chief engineer. “We have managed to achieve superior drive quality when compared to our PHEV competitors due to our exclusively designed EVT.”
Cadillac didn’t stop there, though. The 2016 CT6 PHEV is also equipped with regenerative braking technology. iBooster and Electronic Stability Program have been tailor made for the CT6 to provide maximum energy recovery combined with reduced stopping distance and improved fuel economy over traditional regenerative braking systems.
iBooster and ESP work as generators to slow the vehicle down alongside the traditional hydraulic brake system, capturing as much kinetic energy as possible along the way. This also allows the start/stop feature to engage more often, providing further fuel efficiency.
The 2016 CT6 PHEV will offer three driving modes, including:
- 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.
As seen in the 2016 Cadillac ELR, the 2016 CT6 PHEV will include Regen On Demand. The technology slows the car upon entering a turn for better exit position, and is activated by the steering wheel mounted paddle shifters. Besides the sportier feel, it is able to convert current momentum into electricity to be stored for later use.
We still have questions, though. Cadillac says it won’t be releasing pure-electric or combined fuel economy figures until we approach the car’s introduction in the U.S. and China.
We can expect more PHEVs from Cadillac in the future, with the CT6 being the start. From what we can see on paper, though, the 2016 CT6 PHEV will be a luxurious, sporty, fuel efficient machine.
