What is a 4x4 car?
A 4x4 car is one that is fitted with four-wheel drive, which means that the power created by the engine is sent to all four wheels. This means that if one or more wheels is stuck or can’t get any grip on the road, the other wheels are still driving the car forward.
Some cars have permanent four-wheel drive, so all the wheels are always powered directly by the engine. Other cars have part-time four-wheel drive, so the car mostly uses just two wheels (usually the front wheels), which uses less fuel, but when needed, sends power to all four wheels.
