The Engineering Behind the Magic: Types of Torque Vectoring Systems
Not all torque vectoring systems are created equal. Automotive engineers have developed several ways to achieve this clever power distribution, each with its own advantages and cost implications. Understanding the types helps explain why the feature can be found in a wide range of vehicles.
The main types are:
Brake-Based Torque Vectoring: The most common and cost-effective. It uses the existing ABS hardware to gently brake an inside wheel, effectively transferring more power to the outside wheel with more grip.
Clutch-Based Torque Vectoring: Uses an active differential with electronically controlled clutches. This system can actively send more torque to the outside wheel without wasting energy as heat, making it more efficient and performance-focused.
Drivetrain-Based (Dual-Clutch) Torque Vectoring: The most advanced type, often found in supercars. It uses two separate clutches for the rear wheels, allowing for completely independent power control to each wheel.
FAQ
Q: Which type is best?A: Drivetrain-based systems offer the most precise control but are heavy and expensive. Clutch-based systems offer a great balance of performance and practicality. Brake-based systems are a great way to add handling enhancement at a lower cost.
Q: Can it be added to an older car?A: Generally, no. It requires specific hardware (differentials, sensors, controllers) and deep integration with the vehicle's stability control and engine management systems.
The choice of system is a key differentiator between a good handler and a great one.
