DSC_0858HOW THE ALL-WHEEL DRIVE SYSTEM WORKS

The Haldex all-wheel drive system is an active on demand system that is continuously monitoring many variables, including wheel speed, throttle position, steering wheel angle, and yaw.  The system takes all this into account in determining how much torque goes to the rear wheels and how much goes from side to side in the rear.

The electronic limited slip differential allows the system to control the distribution of power between left rear and right rear wheel.  The advantage of the limited slip is that it significantly improves traction and stability.  Simply put, it keeps the car pointed in the right direction by yaw dampening.

Car buyers pick all-wheel drive for good traction and stability, particularly in winter driving conditions, but Buick’s all-wheel drive is a system for all seasons.

THE ENGINE

The Regal GS is equipped with a transversely-mounted 2.0-liter direct injection turbocharged four-cylinder engine that is also used in the Cadillac ATS and CTS.  It develops 259 horsepower and 295 pound-feet of torque and gets all 295 at 2,500 RPM (it’s at 3,000 in the non-GS model).DSC_0925

The optional Haldex all-wheel drive model comes with a six-speed automatic and differs from the non-GS model in that it uses an electronically controlled limited slip rear differential.  The GS is also equipped with GM’s HiPer Strut active damping technology on all four corners, and it was fitted with the latest Pirelli Sottozero winter performance tires.

DRIVING THE 2014 BUICK REGAL GS AWD

Did you know you can smell rubber burning on ice?

One of the main benefits of all-wheel drive is significantly improved traction and stability.  This is particularly important in snow and ice but it’s applicable in all types of inclement weather.  By testing the car up in the Great White North, we were able to really put the car through its paces.

Here in Mirabel, Quebec, conditions were cold, snowy, and icy.
