We’re quite often asked what’s the difference between 2WD, 4WD and AWD?
2WD is when only 2 wheels are engaged, this can be either front or back wheels depending on the model. On the plus side, it’s cheaper to manufacture and gives good traction. On the downside there can be issues with grip when the vehicle accelerates and the weight shifts.
4WD means a vehicle that drives in 2WD as standard but has a selectable 4WD option for certain situations such as off-road, sand or snow. 4WD vehicles have a low and high range with a centre differential lock up mechanism for off-road conditions when the wheels need to rotate at different speeds. The low range is used for climbing and pulling power or torque while the high range is useful in slippery and uneven conditions.
AWD stands for all wheel drive, it is not selectable and has no low or high range. AWD vehicles drive in 2WD most of the time with sensors monitoring wheel slippage and automatically switching to 4WD depending on the conditions providing improved handling and enhanced performance.
