2017 Cadillac CT6 Plug-In

Cadillac introduces a plug-in hybrid vehicle (PHEV) variant of the CT6 full-eize prestige luxury sedan for the 2017 model year. Thanks to advanced plug-in technology, the luxury sedan rewards drivers with environmentally conscious driving without compromising on performance. In fact, it more than doubles efficiency of the non-plug-in model, delivering an estimated 65 MPGe, fuel consumption of roughly 2.0L/100 km and an all-electric driving range of roughly 37 miles.

“The first-ever CT6 is a technological showcase throughout, making it an ideal platform for Cadillac to offer its first plug-in hybrid,” says 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.”

The 2017 CT6 Plug-In is designed to provide responsive, all-electric driving for most daily commutes, while maximizing fuel efficiency by providing blended power from the engine and battery at higher speeds and higher loads.

The vehicle features an all-electric driving range of over 37 miles (60 km), which is enough for most daily commutes, depending on speed and driver behavior. In addition, the CT6 PHEV provides a total driving range of over 400 miles. To note, CT6 PHEV drivers have no need to find charging stations along their way thanks to the vehicle’s advanced propulsion system, thereby removing all range anxiety for customers.

Fuel efficiency is roughly 65 MPGe, or Miles Per Gallon equivalence. The Metric compares energy consumption of plug-in electric vehicles and other advanced technology vehicles with the fuel economy of conventional internal combustion vehicles in miles per U.S. gallon.

The Cadillac CT6 PHEV achieves the same zero to 60 mph performance of 5.2 seconds — equivalent to its V6-powered competitors, while achieving roughly twice the full EV range and MPGe figures.

On electric power only, the car is capable of approximately 30 miles of driving range and a top speed of 78 mph, with the additional power of the engine adding hundreds of miles of total range and a top speed of 150 mph.

The CT6 Plug-In is powered by a gasoline-powered internal combustion engine, an electric motor powered by a battery pack, and an electric variable transmission sending power to the rear wheels.

Gasoline Engine

The gasoline engine in the CT6 Plug-In is the 2.0L turbo 4-cylinder LTG engine with spark-ignited direct injection and variable valve technology.

Battery Pack

An 18.4 kWh lithium-ion battery pack is located in the rear of the vehicle between the rear seat and the trunk. The battery system is comprised of 192 prismatic pouch cells, which utilize the latest generation chemistry that will be used in other GM vehicles.

With industry-leading quality levels of less than two problems per million battery cells produced, more than 20 million battery cells have been made for more than 73,000 GM plug-ins on the road today.

The CT6 PHEV battery system will use GM’s proven active thermal control system, which maintains electric range over the battery system’s life.

Charging the battery system will be possible using a 220V charger.

Electric Variable Transmission

The CT6 Plug-In mates an all-new rear wheel drive electric variable transmission (EVT) with two exclusively-designed electric motors that each produces 100 horsepower (74.5 kW) of power, providing the smooth and powerful acceleration expected from a driver’s car. The two-motor EVT system combines with the 2.0-liter turbocharged four-cylinder gas engine to produce an estimated total system power of 335 horsepower (250 kW) and 432 pound-feet (586 Nm) of torque, which helps propel the vehicle from a zero to 60 mph in an estimated 5.2 seconds.

The two-motor EVT also uses three traditional planetary gears and is mated to a 2.0L turbo 4-cylinder engine with spark-ignited direct injection and variable valve technology. The use of a two-motor system provides smooth and seamless power through the entire driving range.

Regenerative Braking

The CT6 PHEV features iBooster and ESP-hev regenerative blended braking to provide maximum energy recuperation combined with reduced stopping distance and improved fuel economy over traditional regenerative braking systems.

The iBooster and ESP-hev technology balances the use of the CT6 electric motors to act as generators to slow down the vehicle and capture as much kinetic energy as possible during low demand scenarios, while blending the traditional hydraulic brakes with the motors in high demand scenarios.

As expected from a driver’s car like the CT6, the system provides improved brake pedal feel and enables increased opportunity for engine stop-start operation.

Operating Modes

CT6 PHEV enables drivers to select between three distinct operating modes: 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.

Regen On Demand

The CT6 PHEV also features Regen-on-Demand, which allows the driver to temporarily regenerate energy from vehicle momentum into electricity and store in the battery pack for later use.

Regen on Demand supports a more engaging driving experience by slowing the vehicle when entering a turn to better position it on the exit, much like downshifting with a manual transmission. Regen on Demand is engaged via steering-wheel paddles adapted from traditional performance cars.

The CT6 PHEV was unveiled in April 2015 in Shanghai, China.

The CT6 Plug-In launched in China in December 2016 and is set to launch in the U.S. in the spring of 2017.

In the U.S. market, the CT6 Plug-In is offered in a single unique trim level. Pricing and equipment is comparable to the Premium Luxury trim level, which is second highest within the CT6 model range. It’s worthy to note that the Plug-In model includes numerous optional equipment as standard, such as a Rear Seat Infotainment system, Enhanced Night Vision and Rear Camera Mirror.

The CT6 Plug-In has a U.S. starting price of $75,095 plus a $995 destination freight charge, before any applicable electric vehicle tax incentives.

The Cadillac CT6 Plug-In is produced by GM China at a plant in Shanghai, and exported to other markets, including the United States.

Like its non-electrified variants, the CT6 Plug-In is based on GM’s Omega platform. The advanced lightweight structure helps the CT6 Plug-In achieve impressive fuel efficiency and electric driving performance.
