But four-wheel drive often doesn't work on the road for the exact same reason it works so well off road.

As mentioned before, most vehicles are 2WD, which can come in one of two setups: front-wheel drive (FWD) or rear-wheel drive (RWD). Since the engine only needs to power two wheels, they are cheaper to purchase and get better fuel economy than either 4WD or AWD.

All-Wheel Drive (AWD) vs. Four-Wheel Drive (4WD) 4WD is normally used on large SUV Four-Wheel Drive (4x4) vehicles designed to use the extra traction of 4WD in off road situations. ... This means that when 4WD vehicles are driven on normal road surfaces, 4x4 must be deselected and the vehicle driven in two wheel drive.

How to Drive in Snow With an AWD. AWD, all wheel drive, is the same as 4WD, four wheel drive, meaning all four wheels have power rather than just two wheels. In the snow, AWD is helpful especially when starting from a stop. AWD helps the car gain traction, but does not help at high speeds, on ice, or when braking.

A 2WD (two-wheel drive) car sends engine power to two wheels to get the vehicle moving. Typically, 2WD vehicles are available in two setups: front-wheel drive or rear-wheel drive. Front-wheel drive cars divert power to the front wheels to help enhance traction and stability.

The differential is what allows the wheels to turn at different speeds. The vast majority of rear-wheel drive cars have an open differential. ... If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.

What is 4WD? 4WD, or “four-wheel drive,” is a traditional 4×4 drivetrain. The principle difference between 4WD and AWD is that, while 4WD systems are able to send power to the front and rear axles, they're also able to direct a specific amount of power between the left and right wheels.
