What's the Difference Between All-Wheel-Drive and Four-Wheel-Drive?

  • Mazda CX-5 Driving in the Rain

    All-wheel drive (AWD) and four-wheel drive (4WD) are terms that you may sometimes see used interchangeably. This seems to make sense because “all” the wheels in a car typically add up to four. However, the main difference between AWD and 4WD systems is that an AWD vehicle only activates when wheel slip is detected, while most 4WD systems engage all four wheels when turned on. At Mazda of Gastonia near Gastonia, we’re happy to explore these differences in greater detail. We even offer a selection of all-wheel drive Mazda SUVs.

4 Wheel Drive vs All Wheel Drive

Mazda AWD and 4WD systems essentially do the same thing: they feed power to each wheel rather than those just at the front (front-wheel drive) or just at the rear (rear-wheel drive). However, they go about it in different ways. Let’s see how AWD and 4WD systems really differ:

  • 4WD systems existed first and are found on pickup trucks and vehicles made for extreme off-roading. Most 4WD system are not on by default—they require the driver to engage it manually. In tough snow, mud, or other rugged conditions, you can engage the system, and in regular conditions, you simply turn it off. That makes it good for off-roading, but not for everyday driving.
  • AWD is generally offered on car-based SUVs and performance cars, including the Mazda CX-3, Mazda CX-5, and Mazda CX-9. It helps improve traction off the line and in corners and is a less complicated system than 4WD (and thus also less expensive). Because it is always on, it does tend to reduce fuel economy, but giving a crosser AWD is a much easier way to improve its traction around Kings Mountain than installing a heavy, expensive 4WD system that it might not even use.
