The available active torque control system in the Sienna minivan automatically distributes engine power between the front and rear wheels as needed, enhancing traction on various surfaces. This dynamic system seamlessly adjusts power distribution based on real-time driving conditions, providing enhanced stability and control, especially in challenging weather like snow or rain, or on uneven terrain. It differs from traditional four-wheel-drive systems by prioritizing fuel efficiency, primarily operating in front-wheel drive until additional traction is required.
Enhanced traction control provides a significant safety advantage by improving vehicle stability and reducing the risk of skidding or loss of control. This feature becomes particularly crucial in adverse weather conditions, contributing to a more confident and secure driving experience. Historically, minivans have not always been associated with advanced all-wheel-drive capabilities, often prioritizing fuel economy and interior space. The availability of an active torque control system represents a significant advancement in minivan technology, blending the practicality of a minivan with the enhanced performance and safety benefits of all-wheel drive.
