jagplates Posted May 10, 2023 at 05:37 PM Report Share Posted May 10, 2023 at 05:37 PM Anyone know how the Ford Hybrid transmission does its job? I was under the impression that it was a CVT, which typically includes chains or belts and cones to vary the ratios. But watching a teardown video by Weber Auto, I see that there is nothing in there except a planetary gearset that is locked or unlocked to connect the starter/generator. I realize that an EV does not need a transmission because it has enough torque to move the vehicle without any gear reduction. But, in a hybrid, you have to have some gear reduction to start off when you are using the gasoline engine. These cars perform just fine. They are not sluggish. How the heck does this work?

cr08 Posted May 10, 2023 at 05:50 PM Report Share Posted May 10, 2023 at 05:50 PM (edited) The video basically explains it to you. It is 'Continuously Variable' by name. The starter/generator motor can adjust its speed and direction while driving with the ICE operating to change the ratio. For full EV operation, the main drive motor is essentially directly coupled to the output side so aside from the final drive ratio/differential, it's a 1:1 to the wheels. The CVT aspect only comes into play for the ICE while in hybrid operation. This is the same design that Toyota has used in the Prius all the way back to the first gen models. If you come across any Prius info that explains it better for you, that will also apply here.
