It uses an electronically controlled multi-plate clutch to distribute power to the rear wheels, with a focus on maximizing acceleration and handling. i-VTM4 also features torque vectoring technology to enhance cornering performance.
How Honda AWD Works
Honda’s AWD system is designed to enhance traction and stability, particularly in challenging road conditions. It works by seamlessly distributing power to the wheels that need it most, ensuring a smooth and controlled driving experience.
Key Components of Honda’s AWD System
The Honda AWD system relies on a sophisticated interplay of components to effectively distribute power. These components include:
- Transfer Case: The transfer case acts as the central hub of the AWD system. It receives power from the engine and distributes it to the front and rear axles. It features a multi-plate clutch that allows for variable power distribution based on driving conditions.
- Differentials: Differentials are located in both the front and rear axles. They allow the wheels on each axle to rotate at different speeds, which is essential for navigating turns. In an AWD system, the differentials work in conjunction with the transfer case to ensure optimal power delivery.
- Drive Shafts: Drive shafts connect the transfer case to the front and rear axles, transmitting power from the engine to the wheels. They are typically made of strong, durable materials to withstand the forces of power transmission.
How Power is Distributed to the Wheels
The distribution of power in Honda’s AWD system is a dynamic process, constantly adjusting to changing road conditions.
- Normal Driving Conditions: Under normal driving conditions, the Honda AWD system primarily sends power to the front wheels. This setup maximizes fuel efficiency and provides a responsive driving experience.
- Loss of Traction: When the front wheels experience a loss of traction, such as on slippery surfaces or during acceleration, the system automatically engages the rear wheels. The transfer case’s multi-plate clutch engages, sending power to the rear wheels to improve grip and stability.
- Variable Power Distribution: The AWD system continuously monitors wheel speed and other factors to determine the optimal power distribution. It can send up to 70% of power to the rear wheels when needed, ensuring maximum traction and control.
Honda’s AWD system is designed to be proactive, anticipating potential loss of traction and distributing power accordingly. This ensures a smooth and controlled driving experience, even in challenging conditions.
