1. What Is Torque Vectoring and Why Is It Important?

Torque vectoring is a sophisticated automotive technology that enhances vehicle handling and stability by actively managing the distribution of torque to individual wheels. It represents a significant advancement in vehicle dynamics control, providing improved traction and responsiveness, particularly during cornering and challenging driving conditions.

• Enhanced Handling and Stability: By intelligently distributing torque, torque vectoring systems minimize understeer and oversteer, allowing drivers to maintain better control of the vehicle.
• Improved Traction: Torque vectoring optimizes traction by sending more power to the wheels with the most grip, which is especially beneficial on slippery or uneven surfaces.
• Increased Cornering Speed: With better control over torque distribution, drivers can achieve higher cornering speeds with enhanced stability and confidence.
• Greater Safety: Torque vectoring systems can help prevent loss of control situations by proactively adjusting torque to keep the vehicle on its intended path.

According to a study by the Society of Automotive Engineers (SAE) in February 2024, vehicles equipped with torque vectoring systems showed a 15% improvement in handling performance and a 10% reduction in accident rates on wet surfaces. This technology not only improves the driving experience but also significantly contributes to overall vehicle safety.
