It's just early i-MMD (basically series-hybrid, but also can drive directly by engine on highway) system, according to PR, despite they said "eCVT". It's confusing. They called two motor(generator) connected via electricity (but not connected mechanically) as "eCVT". It uses clutch to switch direct drive on highway. https://global.honda/newsroom/news/2013/4130620eng-accord.ht...
