How can you tell the difference between all wheel drive and 2 wheel drive?

All-wheel drive (AWD) distributes power to all four wheels automatically, enhancing traction on varied surfaces without driver intervention. In contrast, two-wheel drive (2WD) powers either the front or rear wheels only, which can lead to reduced traction in slippery conditions. You can also identify them by checking the vehicle specifications; AWD systems are often marketed for improved handling and performance, while 2WD is typically more fuel-efficient. Additionally, some vehicles have a switch or lever to engage AWD, whereas 2WD is always engaged.
