There was a one-off (ok, 2) created for a Japanese racing series. Not very much Prius was left but they did use Toyota production car hybrid systems.
That's a freaking wild Frankenstein's monster of a car - a Prius front half with a Le Mans V8 in the back seat and a battery pack in the passenger seat. I was giggling when I heard it move out from the pits like a Prius with a beefy e-motor and then the V8 roars to life, sounding like a cheaper version of the mad Porsche 919. You're right, the car used Prius and Camry parts on the EV side.
