When we first drove the Buick Regal GS in Traverse City, Michigan late last summer, we were impressed by the vehicle’s surprising agility and quickness. Unfortunately, we by no means found the top speed of the car. But during the 2012 Nevada Open Road Challenge, the Buick team reached it.
During the run, a radar trap controlled by race operators verified a speed of 162 mph for the Regal GS — impressive for a 270 horsepower four-cylinder engine. This makes the Regal GS the fastest Buick to date. And its front-wheel-drive.
