What is the Difference Between a Driveshaft and a CV Shaft?

The drivetrain system in your vehicle is made up of many parts, each carefully designed to power your car safely. Driveshafts and CV shafts are essential components of the drivetrain system. However, they serve different purposes and are suited for different types of vehicles.

What is a Driveshaft?

Driveshafts transmit torque (the engines rotational force) from the gearbox to the wheels. Driveshafts are usually only found on Rear Wheel Drive (RWD) and 4 Wheel Drive (4WD) vehicles.

What is a CV Shaft?

A CV shaft is a type of driveshaft that has two CV joints on either end. CV stands for Constant Velocity. Constant Velocity Joints transfer torque from the gearbox to the wheels at a constant speed. All Front Wheel Drive vehicles have CV shafts.

What is the difference between a Driveshaft and a CV shaft?

There are many variations of driveshafts across different vehicles. Driveshafts utilise Universal Joints (U-Joints) to connect it to other drivetrain system components, whereas a CV shaft utilises CV joints.

Driveshafts utilise universal joints (U-joints) to connect to other drivetrain system components, some newer cars even use viscous couplings, rubber couplings and CV joints

CV Joints allow a vehicle to maintain speed while turning at a wider range of angles without causing an increase in friction.

What types of cars use CV Shafts?

All front-wheel drive vehicles, such as the Mazda 3, Ford Focus and Volkswagen Golf. Some four-wheel and all-wheel drive also use CV joints, as well as some trucks.

Rear-wheel vehicles and some four-wheel drive and all-wheel drive cars utilise driveshafts.
