You can’t go very far into a conversation about cars without hearing the terms “four-wheel drive” (4WD) and “all-wheel drive” (AWD). These terms are often used interchangeably, but they are far from the same thing. Make sure you know the difference, so you know which one fits your lifestyle best!
Starting with the older of the two, 4WD works very differently than AWD. It’s older and used mainly in off-roading and utility vehicles. 4WD works by supplying power to all four wheels through the transfer case, so the maximum amount of power possible is going to each wheel. It’s not very fuel-efficient but it’s responsible for getting your vehicle through deep mud and over large rocks. 4WD also has to be manually activated and shut down when you are down bouldering.
AWD is much newer and serves a very different purpose. Most people want AWD when they are thinking of 4WD. AWD is controlled through the vehicle’s computer and is turned on and off as needed using sensors on the vehicle depending on the road conditions. It’s much more fuel efficient and uses the system only when needed. AWD is best for maneuvering through wet and snowy conditions.
However, each of these systems merely help your car move over or through obstacles; they do not help you slow down or stop in unpleasant weather. Drive safely!
