Four wheel drive explained

 

FOUR-WHEEL DRIVE (4WD)

A 4WD vehicle has power to all its wheels. However, it’s also possible to activate and deactivate this 4WD element. This is useful because it provides better traction in off-road conditions, which is when 4WD comes into its own. But when you’re driving in town or simply don’t need to worry about snow, mud or difficult terrain, you can turn off 4WD, switch to 2WD, and improve fuel economy. These days, many manufacturers provide 4WD as an option – and cars with these systems tend to have a button or lever to select between 4WD or 2WD. Additionally, some vehicles will automatically detect road surfaces and apply the appropriate driving mode for you, as well as numerous other 4WD settings.
