Recently, electric-powered vehicle such as HV, PHV, EV and FCV has been highly demanded and getting attention due to the increase of environmental-consciousness. Also, environmental regulations are getting more and more strict in many countries and regions. Then, environmental friendly vehicle is needed to be spread more and more than ever. As it is found in “TOYOTA Environmental challenge 2050”, Toyota will rapidly increase the number of new car sales of electric-powered vehicle towards 2050. This paper covers the rear wheel drive Q710 electric drive transaxle for 2nd generation MIRAI FCV. Toyota developed the transaxle for FCV (rear mounted) and for EV (front mounted) simultaneously and achieved coexistence of vehicle mountability and commonization of majority of the parts. This paper describes the hardware feature and the detailed technology which was adopted to Q710. In the 2nd generation MIRAI, the transaxle is mounted under rear floor and contributed to the improvement of drivability by rear wheel drive. In addition, two air-cooled oil cooler are placed in parallel behind transaxle for motor cooling. Based on the adoption of world’s first “differential pressure wind guide oil cooler”, Toyota succeeded in motor cooling by the air-cooled oil cooler which is placed to rear.
