Some of the terminology you come across in ads for new or used cars is pretty straightforward, like the year, make, model, mileage, and category of the vehicle. However, other terms—specifically, “four-wheel-drive” (4WD or 4×4) and “all-wheel-drive” (AWD)—can be a bit more confusing. Here’s what to know about the difference between the two.

What’s the difference between four-wheel-drive and all-wheel-drive?

Given that most cars, SUVs, and non-commercial trucks have four wheels, you might assume that 4WD and AWD are the same thing. But that would be too simple. Complicating matters even further is the fact that some manufacturers come up with their own names for driving systems, like 4MATIC (Mercedes-Benz) and xDrive (courtesy of BMW).

Plus, the two systems tend to appeal to the same group of consumers: Those who live places where rain, snow, and other weather impacts road conditions, and/or people who plan to drive off-road.

Here are some of the main differences between 4WD and AWD, according to Kelley Blue Book and Carmax:

Four-wheel-drive

Designed for slippery, loose, or rugged surfacesSplits power evenly between the front and rear wheels Typically uses rear wheels on paved roadsExcels on steep inclinesMore towing capability than AWDPoor fuel economyMost pickup trucks use it

All-wheel-drive

Designed for on-road useVehicle automatically shifts power between the front and rear wheels to achieve optimal traction
Provides added traction in bad weatherCosts more upfront, but adds value if you sellMore fuel-efficient than 4WDUsed on cars and minivans

There’s more to know, and this guide from Kelley Blue Book has additional information on each system, including what to consider when shopping for a new vehicle.
