On the section for epicyclic CVT's ( https://en.wikipedia.org/wiki/Continuously_variable_transmission#Epicyclic ) the description refers to friction discs and then indicates the Prius E-CVT as an example. The E-CVT is epicyclic but uses differential input from multiple motors to produce ratio variability. There is not a friction component. — Preceding unsigned comment added by 67.5.110.26 (talk) 17:57, 21 January 2021 (UTC)[reply]

Hydrostatic drives are not just for small "lawn mower" applications

Hydrostatic drives are used on quite large earthmoving equipment , notably large bulldozers. Here is an example of a 770HP drive https://www.mobilehydraulictips.com/fluid-power-drives-mega-dozer/ . The section should be reworded slightly to note that hydrostatic transmissions are very efficient at all power levels. Salbayeng (talk) 22:34, 1 September 2020 (UTC)[reply]

Can someone tell me why hydraulic systems are wrongly referred to as hydrostatic ?

In a hydrostatic system the fluid does not move, it is static = not move. All hydraulic power transmission systems rely on fluid movement and are therefore hydrodynamic.
