ABSTRACT - As market needs for environmentally-friendly cars have heightened, Toyota Motor Corporation (Toyota) has developed a new hybrid transaxle (P610) with the goal of achieving both high fuel efficiency and excellent performance. The P610 was installed in the new Prius, which became the first model to adopt the Toyota New Global Architecture (TNGA), a new development strategy promoted by Toyota. The P610 was developed to achieve comprehensive loss reduction as well as size and weight reduction. By adopting such features as a dual-axle structure for the motor-generator, the P610 maximized the potential of the THS (Toyota Hybrid System), contributing to the vehicle's fuel efficiency performance.
