Toyota HSD Technology
Hybrid Synergy Drive combines a petrol engine with the Atkinson cycle, two electric motors (MG1 and MG2) and a compact NiMH or Li-Ion battery through a carefully balanced planetary transmission (e-CVT). The system does not require external charging — the battery charges only while driving and during regenerative braking. It is available in Prius, Yaris Hybrid, Corolla Hybrid, C-HR Hybrid, RAV4 Hybrid, Camry Hybrid and Highlander Hybrid models.
