A 4×4 vehicle is a four-wheel drive vehicle that has power sent to all four wheels. This type of setup is often used for off-road vehicles or vehicles that will be driven in snow or other slippery conditions.

A 4×4 system works by sending power from the engine to all four wheels of the vehicle. This helps with traction and can give the driver more control over the vehicle, especially in difficult conditions.

Four-wheel drive provides power to all four wheels of a vehicle simultaneously. This can be useful in off-road situations where traction is limited, such as in sand or mud. It can also be helpful in winter weather conditions where roads are icy or covered in snow.

One potential drawback of four-wheel drive is that it can decrease fuel economy. This is because the engine has to work harder to power all four wheels instead of just two. Additionally, four-wheel drive systems tend to be more expensive than two-wheel drive systems.

Although they sound similar, four-wheel drive and all-wheel drive are not the same thing. All-wheel drive vehicles send power to all four wheels at all times, while four-wheel drive vehicles only send power to all four wheels when it is needed.
