AWD vs 4WD - What's the Difference?
When you buy a car, one of the options you'll have is the drivetrain. Two common drivetrains are all-wheel drive and four-wheel drive. Your choices might vary based on the trim and model of vehicle that you get. While it might sound like all-wheel drive and four-wheel drive are nearly identical drivetrains if not entirely the same, there are actually some key differences to understand that might make one more appealing or beneficial than the other. Additionally, you might have the option to get a part-time four-wheel drive or four-wheel drive on-demand with your vehicle.
What is All-Wheel Drive?
A car with all-wheel drive uses a powertrain that sends power equally to both the front and back wheels. The wheels receive the same amount of power, and they all get power at the same time. A full-time AWD option continuously moves all four wheels simultaneously at the same speed. If you choose a model with part-time all-wheel drive, you will get a two-wheel drive mode most of the time, but the car will change over to AWD when necessary for extra traction.
The all-wheel drive system in your vehicle is generally automatic, which means that the driver does not need to take any additional action in order for the system to become activated. However, some cars have a dual manual and automatic transmission system that allows you to take control of the gear shifting when you want for a more engaging driving experience.
What is Four-Wheel Drive?
Four-wheel drive is a type of drivetrain that is commonly found in SUVs and trucks. It uses different differentials on both axles. The four-wheel drive drivetrain also has transfer cases and couplings. This setup allows for a more even distribution of power.
Four-wheel drive sends torque to wheels as needed. Rather than having a continuous delivery of power like AWD, vehicles with four-wheel drive get additional power intermittently to the wheels. The four-wheel drive system is often controlled automatically, but you can also find some vehicles that have manual controls for four-wheel drive. Special features such as low-range gearing may be available for better traction and control.
