If you are trying to figure out where your vehicle can take you, understanding its drivetrain is essential. Cars have various drivetrains that you can choose from to ensure that you have a car that can keep up with all the different kinds of driving that you want to do. Two popular drivetrains are all-wheel drive and four-wheel drive. Both drivetrains provide a car's four wheels with power, but they do so in different ways. All-wheel drive gives all four wheels power simultaneously. All-wheel drive distributes power equally among all the wheels on your vehicle. By giving the wheels power at the same time, all-wheel drive optimizes control for the driver and makes a car as fuel-efficient as possible. All-wheel drive is available as a full-time or part-time system. You can also get four-wheel drive if you want a car that handles the elements. The four-wheel drive provides even greater traction and control, which in turn translates to superior performance.
