In the fourth generation, the Prius is the first global model of the brand to be built on the new TNGA platform. This gave a gain in body rigidity (by 60%), plus the car received a lower center of gravity (also due to the low-located power plant). The battery pack is located under the rear seat, not under the trunk. Outwardly, the novelty looks more aggressive and dynamic than its predecessor. The car received a new interior, became quieter at high speeds. The basis of the hybrid system is the same 1.8-liter 2ZR-FXE engine operating on the Atkinson cycle and equipped with the VVT-i system.
Fuse diagrams are relevant for Toyota Prius 4 (XW50) 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022 release.
