How a Hybrid e-CVT Works: Toyota 3rd Generation Hybrid Synergy Drive

Toyota's hybrid system is comprised of using a gasoline engine, two electric motors, a battery pack and a power inverter. These work together to propel the vehicle down the road, ultimately saving fuel and reducing emissions. At the heart of the system is an electronic continuously variable transmission, or E-CVT. It is responsible for blending the power of the electric motors and gasoline engine to propel the vehicle, as well as recoup kinetic energy to charge the battery. The E-CVT is unlike other CVT's that use a conventional cone and belt system. Instead a power split device, aka a planetary gearset, is used, with MG1, MG2 and the ICE connected to each part. MG2 always drives the wheels, while a combination of MG1 and the ICE rotating works to either charge the battery or add power from the ICE to the wheels for additional power. In this video, the transmission from a third generation 2010 Toyota Prius Hybrid is torn down to see whats inside and how it works.
