In the event the ring gear is locked plus the Sunlight equipment is driven, the planet gears transmit push through the World copyright and velocity is lowered.
As for CVT, the engines procedure in bigger successful possibilities to transmit clean and linear Operating. There may be also an L method existing which gives driving on inclines, whether or not it hills, flyovers, or parking loads.
