2017 Cadillac CT6 Plug-in Hybrid
Advanced Plug-In Hybrid technology enables the luxury sedan to emit zero tailpipe emissions and travel at least 35 miles on a full electric charge, after which an on-board engine generates electric power to ensure peace of mind about the location of charging stations. The CT6 Plug-In Hybrid is estimated to have fuel economy exceeding 65 MPGe. Miles per gallon equivalence – MPGe – 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 CT6 PHEV will be introduced in China in the Fall of 2016, with U.S. availability scheduled for early-2017 in very exclusive quantities. Cadillac is experiencing impressive growth in China, widely expected to become the world’s largest luxury auto market overall. “The first-ever CT6 is a technological showcase, 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 exceptional efficiency as well as the strong acceleration and responsiveness of a true driver’s car.” The CT6 Plug-In Hybrid system 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 CT6 Plug-In Hybrid combines an all-new rear wheel drive electric variable transmission to provide the smooth, spirited 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 hp (250 kW) and 432 lb-ft (586 Nm) of torque. This helps propel the vehicle from a zero to 60 mph in an estimated 5.3 seconds. Each electric motor produces 100 hp (74.5 kW) of power. On electric power only, the car is capable of approximately 30 miles of driving range and 75 mph, with the additional power of the engine adding hundreds of miles of total range and a top speed of 150 mph on a track. Battery Technology The CT6 Plug-In Hybrid leverages General Motors’ expertise in battery cell technology with more than 23 million cells on the road today. An 18.4 kWh lithium-ion battery pack is located directly above the rear axle. The battery pack is structurally integrated into the vehicle to maximize body stiffness & driving dynamics. The battery system is comprised of 192 prismatic pouch cells. The CT6 Plug-In Hybrid battery system will use the company’s proven active thermal control system that maintains electric range over the battery system’s life. The battery system can be charged using a 120V or an available 240V charger, allowing a full charge in approximately five hours, depending on outside temperatures. CT6 PHEV drivers will be able to select from three operating modes: Normal: Designed for everyday commuting, this mode provides ideal balance of comfort, performance and maximized EV range and fuel economy Sport: Provides more aggressive torque response for improved off-the-line feel and a stiffer steering response Hold: Allows owners to select when the CT6 PHEV uses its engine, reserving battery charge for later use Chassis The CT6’s rigid, lightweight architecture is the foundation for its segment-challenging agility, enhanced by active-on-demand all-wheel drive, active rear steering and Magnetic Ride Control on the available Active Chassis System. “To put it succinctly, every wheel drives and every wheel steers,” said Hester. “And with Magnetic Ride Control, every wheel’s dampening is adjusted by the millisecond, for responsiveness and driver control unparalleled in the segment.” The chassis system also balances responsiveness with segment-best isolation for exceptional refinement. In the front, the CT6 features a lightweight, aluminum-intensive high-arm multilink short-long arm front suspension. At the rear is a five-link independent suspension that uses multiple outer ball joints and cross braces for optimal handling and steering precision. Active rear steering with the Active Chassis System contributes to greater low-speed agility and high-speed stability. In parking lots, the turning circle is only 37 feet (11.4 m), comparable with the CTS, which has a 114.6-inch wheelbase vs. the CT6’s 122.4-inch wheelbase. Active-on-demand all-wheel drive is also part of the Active Chassis System, making the most of handling and stability in all weather conditions. Its lightweight, compact design and two-gear transfer case enable greater fuel economy than conventional fixed-torque all-wheel drive systems. All-wheel drive is standard on all CT6 six-cylinder models. Selectable Tour, Snow/Ice and Sport modes allow the driver to tailor the CT6’s advanced chassis system for practically any weather or road condition.
