While those of us up here in the north of the country appreciate the extra traction and safety all-wheel drive provides in the snow, the AWD system on the 2014 Buick Regal and Regal GS isn’t just designed to combat harsh Michigan winters. Buick says their advanced system provides extra grip in all weather and road conditions, including on dry surfaces.
The Regal uses a system that can distribute power among the four-wheels by both front and rear and side to side. The Regal shifts torque to the different wheels based on driver input and vehicle data, providing better traction in snow and icy conditions.
The all-wheel drive system uses the same tactics when blasting down a curvy county road. With the ability to transfer power to its rear-wheels, the Regal AWD provides extra traction and reduces torque-steer when the driver needs it most, such as accelerating out of a corner.
“With power going to all four wheels and the ability to transfer power to the wheel with the most grip, we’ve helped enable the driver to have maximum control on all surfaces,” said James Walter, Regal AWD engineer. “This system is constantly monitoring several inputs and anticipating action. It can be very beneficial in keeping the rear of the car balanced during an emergency maneuver.”
When not in the bends, the all-wheel drive system splits torque 50/50 between the front and rear wheels. In the Regal GS, selecting sport or GS Interactive Drive Control modes enables the system to deliver 15 percent more torque to the rear wheels for improved traction and stability under spirited driving. A Haldex module uses a electronic limited slip differential to shift torque between the two rear-wheels, reducing torque steer and understeer and thus increasing grip.
All-wheel drive is available in conjunction with all 2014 Buick Regals equipped with the 2.0 liter turbocharged four-cylinder engine.
