The transmission is connected to the engine through the clutch. The input shaft of the transmission therefore turns at the same rpm as the engine, which improves both power output and fuel economy. CVTs became common in hybrid cars because they are considerably more efficient than both manual and traditional automatic transmissions, and their popularity skyrocketed from there as automakers competed for the best possible fuel economy ratings. As of late 2016, one out of every four cars sold in the United States was equipped with a CVT.
The picture to the left shows how, when shifted into first gear, the purple collar engages the blue gear to its right. As the graphic demonstrates, the green shaft from the engine turns the layshaft, which turns the blue gear to its right. This gear transmits its energy through the collar to drive the yellow drive shaft. Meanwhile, the blue gear on the left is turning, but it is freewheeling on its bearing so it has no effect on the yellow shaft.
Here are all the wacky gear shifters from the New York Auto Show
The dual-clutch automatic operates via two clutches, which are controlled by the car's computer network and require no input from the driver. As we discussed, when the clutch in a manual transmission is engaged, it disconnects the engine from the transmission to enable the shift. The dual-clutch automatic operates two different gears at once, which completes the shift while bypassing the power-disconnect stage. That allows a dual-clutch transmission to complete shifts much more quickly, since there isn't a "pause" while the engine and transmission try to match back up. 2ff7e9595c
