4WD
4 Wheel Drive - A drive system where the engine drives all four wheels, 4WD helps improve traction under many circumstances. 4WD can be part-time (sometimes 2-wheel drive) or full-time (always 4-wheel drive). |
| 4WS
Four (4) Wheel Steering - A generic term that covers a number of very different types of steering systems. Basically, there are two broad categories of four-wheel steering: A. Stability type steering -- steers the rear wheels in phase with the front wheels to enhance the stability of the vehicle during abrupt maneuvers at normal road speeds. B. Maneuverability type steering -- steers the rear wheels in the opposite phase with the front wheels to reduce the turning circle during low speed, tight cornering. This "phase delay" also includes opposite phase steering at high speed. |

Gearshifts are initiated using the steering-wheel mounted paddle or the gear selection lever in the central console. Within milliseconds, the electro-hydraulic system shifts to the selected gear. The system also prevents over-revving: accidental gear shifts are automatically repressed.
When starting off, the Launch Control feature ensures that the de-clutch timing and engine speed are perfectly synchronised for optimum acceleration. When downshifting while driving, the transmission system automatically increases engine speed briefly between gears, ensuring extremely smooth transitions.
