While this things are often mentioned as a new technology, CVTs have actually been around for over a century. They were first used in transportation all the way back in 1896 when Milton Reeves applied his variable-speed sawmill transmission to his first car. Ten years earlier, Diamler-Benz had filed a patent for the first friction belt style CVT, though its unclear if the German manufacturer ever explored the idea further.
In the video below we have an animation that shows one of the several designs for continuously variable transmissions that work to keep the engine speed fairly constant while accelerating the car and maintaining speed. This things will allow the engine to operate at his most efficient operating RPM, which will help considerably with fuel economy.
It has efficiency ratings at 88%, which is less efficient than a full manual transmission, but should be a bit better than a typical automatic gearbox which rely on traditional gear sets and a torque converter to transfer power from the engine to the drivetrain. We also have to mention that CVT isn’t really used in high horsepower applications, which is where the transitional style transmission is still much needed. With both designs available with modern electronic controls and precision manufacturing, they do their intended jobs very well, and we know automakers are constantly pushing the envelope to advance both reliability and efficiency, so expect even more advances in this area in the near future.
