Buick today announced a minor reshuffling of powertrain options for the Regal sedan. For the 2013 model year, the company will make a mild-hybrid system standard on all base Regal models, and will add an automatic transmission to the high-performance Regal GS.
The 2013 Regal will be equipped as standard with General Motors' new eAssist powertrain, replacing a 2.4-liter inline-four as the car's base engine. The eAssist system combines a 182-hp 2.4-liter inline-four engine with a 15-kW electric motor, yielding EPA fuel economy figures of 25/36 mpg (city/highway) for the Regal sedan. The eAssist setup also can be found in Buick's LaCrosse sedan, as well as the 2013 Chevrolet Malibu. Pricing and an on-sale date for the 2013 Regal will be announced later.
"By making the advanced eAssist powertrain standard on a second [Buick] vehicle, we are putting the spotlight on smart technology," Buick marketing vice president Tony DiSalle said in a statement.
Buick also announced that the 2012 Regal GS will offer an optional, no-cost automatic transmission. When the performance sedan was launched, it was only available with a six-speed manual. The new six-speed automatic, which offers manual shifting, is designed to broaden the appeal of the Regal GS. The most powerful version of the sedan, the Regal GS employs a turbocharged 2.0-liter inline-four engine with 270 hp and 295 lb-ft of torque.
Buick says the automatic-equipped Regal GS can run the 0-to-60-mph sprint in a claimed 6.7 seconds, and will return fuel economy of 19/27 mpg -- identical to the manual-transmission car. The company hopes offering the automatic transmission as a no-cost option, "simply makes the performance of the GS even more accessible."
