Torque-vectoring differentials contain additional gear trains, sensors, and electronics that process complex data to enhance traction and overall performance. Torque-vectoring differentials actively distribute torque between the two output shafts, even when they’re rotating at different speeds. This helps improve traction, handling, and performance in a variety of conditions.
In a torque-vectoring system, sensors monitor parameters such as wheel speed, vehicle speed, steering input, and lateral acceleration. Based on this data, the system can determine the optimal power distribution between the left and right wheels of the same axle in real-time. When one wheel is slipping, the system automatically transfers torque to the other wheel, preventing it from spinning too fast. And when entering a corner, more power is sent to the outer wheel to reduce understeer and help the vehicle turn more effectively.
Sports cars, muscle cars, all-wheel drive vehicles and off-road vehicles are most likely to be equipped with a torque-vectoring differential.
Torque-Vectoring Differential Pros and Cons
Advantages of torque-vectoring differentials include improved cornering, enhanced traction, precise control and handling, and versatility. Torque vectoring can be customized for different driving preferences, from comfort-oriented to high-performance settings.
The main drawback of torque-vectoring differentials is their cost and complexity. For this reason, they are more commonly found on more advanced and higher-end vehicles.
