Toyota's Hybrid System (THS) is a remarkable piece of engineering, standard in new RAV4s, featuring two electric motor-generators and a planetary gearset instead of a traditional transmission.
The THS operates with Motor-Generator 1 connected to the engine and Motor-Generator 2 connected to the wheels, allowing the engine to function in series or parallel with MG2, resulting in a reliable and efficient system with fewer components.
Toyota's move to lithium-ion batteries in THS cars, like the upcoming 2026 RAV4, offers improved fuel economy and reduced emissions compared to gas-only models, showcasing the benefits of hybrid technology.
While other automakers offer similar hybrid systems, Toyota's THS stands out for its proven effectiveness and the company's commitment to hybrid technology, making the hybrid option a compelling choice for buyers.
