The Regal GS is powered by an Ecotec 2.0L direct-injected turbocharged four-cylinder engine that generates 270 horsepower and 295 lb-ft. of torque. The 2.0L is mated to a standard six-speed manual transmission although a six-speed automatic will be available later in the model year. Mated to the six-speed manual the Regal GS gets 27 mpg on the highway.
Some of the features that come standard on the Regal GS are a push-button start, leather-wrapped, flat-bottom sport steering wheel with audio controls, metal sport pedals, and leather-appointed, heated and 12-way adjustable sport seating. A Harman Kardon premium 336-watt, 5.1 Matrix Surround Sound system with nine speakers is also standard.
GM also announced the pricing for the mild-hybrid eAssist system that is available on the base Regal. It’s a $2,000 option that delivers 36 mpg on the highway and 25 mpg in the city. The eAssist system mates the 2.4L four-cylinder engine to a lithium-ion battery and electric motor. The mild-hybrid system is also available on the 2012 Buick LaCrosse.
“Regal with eAssist and Regal GS offer distinct advantages to midsize luxury sport sedan customers,” said Tony DiSalle, U.S. vice president of Buick Marketing. “The eAssist’s advanced technology delivers the most fuel-efficient option, while the high-output GS is the sportiest expression of Regal to date.”
