New Cadillac CT6 spawns plug-in hybrid version

By ,

Cadillac will add to its all-new CT6 prestige sedan an available Plug-In Hybrid Electric (PHEV) propulsion system that's expected to more than double the fuel economy of the conventional powertrain offerings. 

The standard CT6 was already hailed as a class leader due to its lightweight and efficient platform.

The CT6 Plug-In Hybrid system is designed to provide 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, even when energy is stored in the battery. 

More specifically, the future Cadillac CT6 PHEV will use General Motors’ proven battery technology consisting of an 18.4 kWh lithium-ion pack located between the rear seat and the trunk. The battery system, comprised of 192 prismatic pouch cells, can be charged using a 120V or 240V charger. Meanwhile, the 2.0L turbocharged 4-cylinder engine and electric motor are capable of producing a total of 335 hp and 432 lb-ft of torque.
