In case your interested. > **[Toyota unveils advanced engines for 2017 and beyond](https://newatlas.com/toyota-tnga-engines/46830/?li_source=LI&li_medium=default-widget)** > > Toyota has unveiled new engines based on its Toyota New Global Architecture (TNGA), to be used in both standard gasoline and hybrid vehicles. The company says that the recently-developed, more efficient engines will begin rolling out in 2017. ---

Looks interesting. ---

_hybrid system …, involving one electric motor acting as a generator and another as a power unit for the drivetrain._ I always understood that electric/hybrid cars used the motor as a generator. splitting the functions up to two units seems strange ?? ---

Wow, 13:1 and 14:1 compression ratios. Race car only stuff only a decade ago. Maybe the split motor system is to allow one motor/generator to act as a starter motor, a generator and a torque booster while the other acts as a torque booster motor and brake reclamation generator. ---

> [@BillRussell](#): > > I always understood that electric/hybrid cars used the motor as a generator. splitting the functions up to two units seems strange ?? _“Toyota will introduce 17 versions of nine new engines and 10 versions of four transmissions from 2017 to 2021. These will be combined with new electrified components for 10 versions of six new hybrid-electric drive systems in that timeframe.”_ I would point to this statement as a suggestion that there’ll be a whole lot of different powertrain architectures when all is said and done. I wouldn’t expect any of them to be conventional. I guess we’ll all find out together later this year. There’s so much in the article that I, for one, will take some time to digest it all. I guess I’m not as fast as I used to be. 😜 ---

Toyota’s system uses two electric motors, always has I think.
