Four-wheel drive and all-wheel drive: I thought they were the same!

March 9, 2010
So tell me the difference between four-wheel drive and all-wheel drive … because I could’ve sworn they were the same! Au contraire! First, let’s talk about four-wheel drive (4WD). This drive allows the driver to switch from two-wheel drive to four-wheel mode, depending on your driving situation. And there are two settings for 4WD: High and low. The 4WD low setting should only be used in extreme off-road situations. So, for all you road ragers out there … now you know! IMG_0697-645x483Now, let’s look at all-wheel drive (AWD). All-wheel drive is similar to 4WD, but has no 2WD option. It will always be operating in 4WD. There is no on/off switch. This is why AWD vehicles are more expensive than 4WD. Bonus fun fact: What is overdrive? I’ve heard it used before, but never knew exactly what it meant. In simplest terms, overdrive allows you to maintain high speed with lower RPMs, which therefore increases your fuel economy. Do you have any burning car questions? Lemme know and I’ll find an answer for you!
