Buick Regal GS
The GS is a made-for-America performance version of the Buick Regal. Buick engineers wanted to balance that performance with the smooth ride and quietness customers expect from Buick, GM executives said.
Fuel economy was another major factor, so the GS uses a turbocharged 4-cylinder engine that produces 255 horsepower. GM promises a zero-to-60 time under seven seconds.
Drivers will be able to switch the car's steering and suspension settings to three different settings: standard, sport and, for tightest feel, GS.
GM hasn't announced pricing for the GS, but it's expected to go on sale in the second half of next year.
