All-Wheel-Drive and Four-Wheel-Drive Are Similar, But Different
There is always some confusion about the definition of all-wheel-drive and four-wheel-drive systems. Both of them provide the means of powering all four wheels of a vehicle in order to provide extra traction, but they both differ in function.
Four-wheel-drive vehicles are typically pickup trucks and off-road SUVs. The four-wheel-drive systems work by using a lower gear ratio and a split differential. They are mostly utilized in off-road and rough terrain conditions.
All-wheel-drive systems are found in high-performance cars, sedans, and crossover vehicles. In this scenario, power is delivered to each wheel evenly, with modification on the fly due to road conditions. The result is a smooth, steady ride with a system that has great results in difficult weather such snow, ice, and heavy rainstorms.
By having each system available, consumers have the opportunity to choose the type of system that will serve them best depending on the driving style that they prefer.
