ABOUT US:
Weber State University (WSU) - Automotive Technology Department - Transmission Lab. A comparison and demonstration of the 3rd Generation Toyota Hybrid Transaxles used in the 2010-2015 Prius family (P410, P510), 2006 - 2017 Highlander HV family (P310, P313), and 2007-2017 Camry HV family (P311, P314). How an eCVT Works. eCVTs allow the engine to operate (when necessary) at the RPM for peak efficiency while increasing and decreasing the transmission drive ratio to change vehicle speed.

We teach advanced vehicle technologies to our automotive students at Weber State University and online. For more information visit: [ Ссылка ]

This video helps satisfy NATEF Task A2.C.24. "Describe the operational characteristics of a hybrid vehicle drive train. (eCVT)", a priority 3 task.

Push-belt CVTs are different and are demonstrated in other WeberAuto videos here [ Ссылка ] and here [ Ссылка ]

This video was created and edited by Professor John D. Kelly at WSU. For a full biography, see [ Ссылка ]
