All-wheel drive (AWD):
Sometimes confused with four-wheel drive (4WD). This drive system features four, full-time active drive wheels that reduce slippage and provide greater control of the vehicle.

When a sensor detects that a wheel is decelerating too rapidly the EHCU (electro-hydraulic control unit) is activated. The EHCU modulates the brake pressure across the appropriate brake lines so as to prevent wheel lockup and help the vehicle maintain directional stability in potentially hazardous braking situations.
The ratio between the width and height of the tyre. Tyres with lower aspect ratios (usually found on sports models), provide superior handling but a harsher ride.
