SH-AWD System: Operation

WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

In a normal turn, the radius of the front wheels is shorter than the radius that the rear wheels travel If the front and rear wheels are driven at the same speed, full power is not transmitted The SH-AWD system monitors the speed of the front wheels and increases the speed of the outside rear wheel proportionally around the larger radius This improves stability and steering response On slippery surfaces, this provides the improved traction of a 4-wheel drive system
