General Motors Co. says its Buick brand will offer several new powertrain technologies on new and refreshed models in China this year, and it plans to launch unspecified all-electric and plug-in hybrid vehicles there by the end of the decade.

This year’s China powertrain additions include GM’s electrified range-extender system, downsized Ecotec engines and the 9-speed automatic transmission the carmaker co-developed with Ford Motor Co. The turbocharged engines will be available in 1.0- and 1.3-liter displacements.

The range extender technology combines GM’s electronic controlled intelligent variable transmission, permanent-magnet dual electric motors drive unit, a direct injection engine and a liquid-cooled lithium battery pack. A similar system is used to power the Chevrolet Volt hybrid sedan.

The Buick models in China will feature a single-cylinder architecture and pair the turbocharger with a twin injector system to boost performance.

All Buick vehicles sold in China this year will include a stop-start system that automatically turns the engine off during idling. And more than 80% of the engines offered by Buick in China by 2018 will be turbocharged, GM says. The carmaker has sold more than 8 million Buick vehicles in China since it launched the brand there in 1998.
