With its new-structure auxiliary transmission system, the next-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.
Introducing the features and the structure of "Jatco CVT7", the world's first CVT equipped with sub transmission.

The main technologies used to realize low fuel consumption and reduction in size and weight are as follows.
The revolutionary-structure which combines of the belt CVT with an auxiliary transmission (two-step gear change) realizes the world's highest*2 transmission gear ratio, as well as enhanced responsiveness on starting and acceleration and improved quietness in high-speed driving.
Reduction in pulley size, oil agitation resistance, etc. realize friction cut by 30% compared with conventional CVTs of the same class.
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.
