ALL-WHEEL DRIVE(AWD): Describes a variation of a four-wheel drive (4WD) vehicle that has been designed to improve on-road traction in unfavourable road conditions or for ultra-high-performance driving thanks to its ability to provide greater driver control over the vehicle and reduce wheel slippage. AWD splits engine torque between the front and rear wheels on demand and is not designed for off-road use.
AUTOMATIC FOUR-WHEEL DRIVE (A4WD): Describes a driving system that can be programmed to automatically or manually engage 4WD depending on driving conditions or road surface quality.
EQUAL POWER DISTRIBUTION: Describes a system used in four-wheel-drive vehicles that ensures an equal amount of power is passed to the front and rear wheels.
FOUR-WHEEL DRIVE (4WD): Describes a drive system in which both front wheels are connected to their differential and axles, and both back wheels are connected to their differential and axles.
FRONT-WHEEL DRIVE(FWD): Describes a vehicle pulled by its front wheels rather than being pushed by its rear wheels.
PERMANENT FOUR-WHEEL DRIVE: Describes a situation where a vehicle’s drive is permanently engaged in four-wheel mode (with lockable or limited-slip differentials).
REAL-TIME FOUR-WHEEL DRIVE: Describes a form of automatic four-wheel-drive engagement implemented employing an electro-hydraulic clutch incorporated in the drivetrain.
REAR-WHEEL DRIVE TRANSAXLE (RWD): Describes a rear-wheel-drive construction taking in a transmission-differential unit that sits between the rear wheels of a front-engined car, ensuring good acceleration without wheelspin even on cars fitted with powerful engines.
SPUR DIFFERENTIAL: Describes a differential in a front-wheel-drive vehicle that uses spur gears instead of bevel gears.
TRANSFER CASE: Describes a device found in a 4-wheel-drive vehicle that allows power to be delivered to both axles.
