How does Buick take a turbocharged two-door coupe and give it the ride comfort and stability for which they have always been known? Well, in the case of the 2011 Regal CXL Turbo, they didn’t. The torque steer was terrible and it just didn’t feel like a Buick. These issues, however, didn’t go unnoticed by the engineers. They knew that coming up with a new suspension for the 2012 Buick Regal GS was imperative, and it was back to the drawing board. They realized that this isn’t just your Grandfather’s Park Avenue. This car is young and sporty.
What they came up with is the HiPer Strut system. Short for High Performance Strut, this unique suspension system is a vast improvement. The added components enable the steering knuckle to rotate independently from the strut tower, creating a better separation between steering and shock absorption. This improves camber control and also maintains ideal suspension geometry. And now with the Buick Interactive Drive Control System, the driver can control the suspension stiffness through the "Sport" and "GS" buttons.
With HiPer Strut, the torque steer that was prevalent in the 2011 Regal is almost nonexistent now, and steering response and control are improved significantly. These enhancements allowed engineers to place a 270 horsepower turbocharged four cylinder in the Regal GS. This advanced 2.0L replaces the old 220 horsepower four-banger and has the highest horsepower-per-liter ratio General Motors has ever produced.
“HiPer Strut raises the limits of how a front-drive car can perform.” said Lead Engineer Bill Rietow.
Buick is not just for elderly ladies and gentleman anymore. They really are appealing to a broader base now and are making the changes necessary to please the younger crowd.
