Since the CVT is continuously variable, it not only avoids the shift-shock and peaks and dips in torque transmission associated with a conventional AT, but also maintains optimum torque for any given power demand. A conventional AT needs step shifts of fixed gear ratios. The CVT, on the other hand, changes gear ratios "steplessly", so that the engine can run at optimum combustion efficiency.

This makes the CVT an exceptional transmission, one which delivers smooth and powerful driving performance together with excellent fuel economy.

Quick to appreciate the CVT's benefits of fuel economy and seamless acceleration, Nissan offered CVTs as early as 1992 in the March and Cube, followed by the 1.8-liter Primera and other models.

Through innovations in CVT components, including the torque converter, oil pump, and belt and control system, in 2002 Nissan overcame the technological challenges to adapting the CVT to high-torque engines. The resulting XTRONIC CVT-M6 was the world's first practicable CVT for engines with displacements as large as 3.5 liters.

Today, Nissan's CVT technology contributes to smooth, fuel-efficient, and fun driving performance in wide range of Nissan models, from compacts to high-powered luxury vehicles.
