The plug-in hybrid version of Cadillac’s CT6 large luxury sedan, which made its debut at this month’s Shanghai Motor Show, will use a version of GM’s second-generation Voltec hybrid system.
The 18.4 kWh battery pack is the same size as the one in the 2016 Chevrolet Volt, which should give the new Caddy an electric range of at least 30 miles. It is not identical, however: whereas the Volt uses a T-shaped pack fitted into the central tunnel, the CT6’s pack sits “between the rear seat and the trunk,” according to GM.
The corded Cadillac has a turbocharged 2.0-liter four-cylinder gas engine and two electric motors, giving it total power of 335 hp (250 kw) and torque of 432 lb-ft.
The new Cadillac has a much larger battery pack, and thus more electric range, than competing PHEVs from Mercedes, BMW and Volvo. In fact, it should deliver more electric miles than any other PHEV except the Volt.
“The CT6 Plug-In Hybrid system is designed to provide all-electric driving for most daily commutes,” Cadillac said, “while maximizing fuel efficiency by providing blended power from the engine and battery at higher speeds and higher loads, even when energy is stored in the battery.”
The plug-in CT6 is expected to show up at dealerships late in the first half of 2016.
