Buick is set to launch two new 2012 Regal models. One is the fuel-efficient and eco-friendly hybrid Regal eAssist, the second is the high performance Regal GS. The Regal GS boasts 270hp and 295lb-ft of torque from its 2.0-liter turbocharged engine. This trim will feature a six-speed manual transmission and eventually carry an optional six-speed automatic. Regal with eAssist uses a variety of advanced technologies to deliver 25mpg in the city and 36mpg on the highway.
