Nissan and JATCO have just announced a new continuously variable transmission that features a wider ratio spread than any previous example of the type. The maximum spread from low to high in the past has been 6:1 but Nissan/JATCO have expanded that range to 7.3:1, a change that offers better fuel efficiency. Since this is a friction belt type CVT, expanding the ratio spread can normally be problematic because of the physical limitations of bending the steel belt around the pulleys.
