The Volkswagen ID.4 crossover electric SUV, the second model in the automaker’s new series of all-electric vehicles, features for Europe and China an optional Continuously Variable Semi-Active suspension with external valve (CVSAe) technology from Tenneco. The CVSAe system is advanced suspension technologies available within Tenneco’s Monroe® Intelligent Suspension portfolio. It is engineered to address the increased inertial loads encountered on vehicles equipped with battery packs and is also featured as an option on the Volkswagen ID.3 hatchback, now available in Europe.
CVSAe semi-active dampers include several designs and construction features that reach load capacity and damping force tuning range for vehicles equipped with lithium-ion battery packs. The added weight of EV batteries can increase damping requirements in a sort of driving situations. CVSAe technology automatically applies added damping force in these situations to reduce body pitch, or “brake dive,” while maintaining outstanding ride comfort.
The system senses and continuously adapts to changing road and driving conditions via four electronically controlled dampers. An electronic control unit (ECU) processes various sensor inputs and adjusts the electronic valve to individually control the performance of each damper. The driver can select a preferred driving mode, either Comfort or Sport, to experience the desired ride and handling characteristics.
“CVSAe technology helps elevate the driving experience, whether in an urban environment, on a highway or a winding road,” said Henrik Johansson, vice president and general manager, Advanced Suspension Technologies, Tenneco. “We are confident that consumers who choose these new Volkswagen models will enjoy the differentiated ride and handling of our proven, highly versatile suspension.”
CVSAe suspension technology from Tenneco is featured in more than 40 popular vehicle models. To learn more, visit www.monroeintelligentsuspension.com
