How was the e-ray judged?Sorry, at this point it almost feels like you are trying to troll.
That said, ZF produces a solution that automakers can use without standing up their own motor manufacturing line, or trying to integrate transmission management, engine management, and motor management, likely from 3 different manufacturers.
Including the motor in the transmission also allow for the cooling systems on the transmission to be used to cool the motor. MOST differentials are passively cooled, so it would require yet another cooling system for the electric motor.
Using the all-in-one solution simplifies the use of an EV. You choose the system you want (no EV, Mild Hybrid, Plug in hybrid), and RWD or AWD and that spits out the transmission you install in that particular vehicle. Now you only need to integrate your drive/engine management system with your transmission, which is something all vehicle manufacturers do, and that's it. Your engine, their transmission, done. While there are a few other choices that need to be made, these are the big ones.
TLDR, the engine+Transmission/motor package reduces complexity vs three separate modules of motor+engine+transmission.
