With its new-structure auxiliary transmission system, the new-generation CVT increases the gear ratio range, and friction-reduction technology and realizes enhanced fuel efficiency as well as great driving performance, aiming for significantly improved environmental performance as highly expected. Furthermore, the reduction in size and weight expands its applicability to a broader range of vehicles including mini-vehicles and small-sized vehicles.

The world-leading level gear ratio coverage for enhanced quietness, and responsiveness on starting and acceleration

The revolutionary-structure which combines of the belt CVT with an auxiliary transmission (two-step gear change) realizes the world-leading level gear ratio coverage, as well as enhanced responsiveness on starting and acceleration and improved quietness in high-speed driving.

世界トップレベルの変速比幅で発進・加速性能と静粛性を向上

Reduced friction

Reduction in pulley size, oil agitation resistance, etc. realize friction cut by 30% compared with conventional CVTs of the same class.

フリクションの低減

Smaller and lighter

The two-step gear change by an auxiliary transmission realizes smaller pulleys, reducing the overall length by 10% and weight by 13% compared with conventional CVTs of the same class.

小型軽量化

Characteristics of Jatco CVT7 W/R

Ratio coverage of 8.7 realizes high fuel performance

Expands the use range of the highest efficiency ratio based on the CVT7 to improve both mode and actual fuel efficiency.

Pursuit of outstanding drivability

Controls excessive increase in engine rotation and acceleration at engine start by locking up after engine start.
