This transaxle is used in the fourth-generation Toyota Prius sold in the U.S.A. from the 2016 model year and above, as well as in the 2017 and later Prius Prime (Prius Plug-In outside the U.S.A.). The new 2018 Camry Hybrid P710 transaxle is similar to the P610, but larger to handle almost 45% more torque from the new A25A-FXS direct-injected engine.

ADDITIONAL TRAINING FOR YOU Join us for hybrid and electric vehicle training with two online courses and a 5-day on-campus boot camp with Professor John D. Kelly. See http://www.weber.edu/evtraining This video was created and edited by Professor John D. Kelly at WSU. For a full biography, see http://www.weber.edu/automotive/J_Kel... Questions: 1. What is the Toyota New Global Architecture (TGNA) system? 2. How much does the P610 weigh? 3. How much case width was lost with this "new" parallel axis transaxle design? 4. What does "Parallel axis design" mean? 5. Where is the inverter with converter located in relation to the transaxle? 6. How is this transaxle cooled? 7. What unique component does the Prius Prime use to prevent the engine from spinning backward? 8. What is unique about the ring gear of this transaxle? 9. What is unique about the stator windings on this transaxle versus most earlier models? 10. What is the purpose of rotor resolvers? 11. What is the purpose of the "Power Split Device" planetary gear set? 12. On the Prius Prime, how many revolutions of MG2 are required to obtain one revolution of the tires? 13. What is the purpose of MG1? 14. What is the purpose of MG2? 15. How does the engine contribute torque to MG2 to help move the vehicle?
