Available in the 2016 ATS, CTS and Escalade, the company’s all-new 3.6-liter six-cylinder engine takes advantage of cylinder deactivation to help improve efficiency. Like the V8 engines in the Escalade and CTS-V, the downsized powerplant seamlessly switches to just four cylinders when load requirements are light.
The upcoming CT6′s new twin-turbo mill is claimed to be the world’s first six-cylinder engine to combine turbocharging with cylinder deactivation and start/stop technology.
Cadillac no longer relies on the car’s primary battery to run the stop/start system. Instead, the starter is powered by separate supercapacitors. The improved approach is said to enable smoother and quicker restarts, while reducing strain on the vehicle’s core electrical system.
Cadillac’s 2.0-liter turbocharged engine, available in the ATS and CTS, also benefits from stop/start tech. Further improving efficiency, the company has continued to expand availability of GM’s latest eight-speed transmission.
“While these new systems increase efficiency, a main focus in engineering at Cadillac is to integrate these systems smoothly with no compromise to the driving experience,” said Cadillac chief engineer David Leone. “Our new 8-speed transmission was developed internally for fast and smooth shifting in every situation with Cylinder Deactivation and Start/Stop are integrated in a more seamless manner than our competitors.”
