Continuous Variable Transmission　(CVT)

CVT is attracting attention for its capability to raise fuel efficiency and enable smooth cruising.

*The mileage figures shown here are based on the assumption that a car is driving in the 10・15 mode. The figures could be different depending on driving and other conditions.

CVT stands for Continuously Variable Transmission. It’s a non-stage transmission, using pulleys instead of gears, that enables constant smooth speed changes.

Belt-type CVTs are now most popular.  In this system, two variable-diameter pulleys and a belt passing through them enable continuous changes of speed.

Since the CVT can constantly maintain the transmission ratio that best suits driving conditions, power loss is small, meaning low fuel consumption. It also makes possible smooth cruising and acceleration.

CVT is the ideal transmission system in this age, for its eco-friendliness realized by improved fuel efficiency that helps to cut CO2 emissions, as well as for its superb cruising performance.

Long leading the world in small car manufacturing, Daihatsu has pursued CVTs that best suit minivehicles. Our goal is to further enhance environmental functions of minivehicles, which are already eco-friendly due to their fuel-efficient, low-emission, and resource-saving characteristics, and to add vigor and a comfortable driving performance. The idea took form when we developed our next-generation CVT, the world’s first Input Reduction 3-shaft Gear Train unit.

With its high fuel efficiency, smooth acceleration, and light and compact character, the new CVT will expand the possibilities of minivehicles..
