Hemi Prius
 

There's a Hemi Prius in the Hybrids forum.

Practical Performance Car (Practical Performance Car (PPC) magazine, a monthly publication aimed at real car enthusiasts, with real-world cars.) bought a Prius, to carry out their basic idea of "put a V8 in it". They decided not to as it was a Mk1 Prius and reckoned nobody would know what it was.
