It was indeed. Who would have thought The Prius was just a copy of an e34?
Though I a doubt it included regenerative braking, as my German is nowhere near good enough to read the article :-(. I don't think in 1994 they would have termed it 'Regenerative Bremsen', so maybe I missed the explanation if there is one. Certainly some incredible history that someone was innovating with CVT+M42+EV.
And it looks like a radial electric motor, too!
IIRC that article was posted here many years ago. As it pre-dates pdf with text, translation does not work, without OCR.
Regardless, I was very happy to get it added to the E34 page on Wikipedia, where others have added more info over time.
