The CT6 weighs 3700 lb (1678 kg) in base-curb form with 265-hp (197 kW) 2.0-L turbocharged I4 and rear drive—5 lb (2.2 kg) lighter than the smaller CTS. Overall it is a technological tour de force, as competitors will ultimately discover in their first teardown analyses. Its top-line powertrain features a Cadillac-exclusive 3.0-L V-6, SAE rated at 400 hp (298 kW) and 400 lb·ft (542 N·m) and using the industry-first combination of twin turbochargers, direct injection, cylinder deactivation (General Motors’ new system for OHC valvetrains), and stop-start.

Power is delivered to either the rear wheels or all wheels, depending on driveline configuration, via GM’s new 8L45 eight-speed planetary automatic. An automatic decoupling AWD is standard on V6 cars. A new 3.6-L naturally aspirated V6 also is available, and GM’s new family of light-vehicle diesels currently under development will provide four-cylinder and V6 engines for European CT6 models within three years, a GM executive said.
