I have a bunch of old bookmarks I could go though. I was looking for 100 hp and never found anything. If I have time I'll see what I can turn up, seems like there was more than one at 25 hp, a golf cart thing maybe. It was not cheap, that much I do remember.

The typical cheap pancake motor can peak at 25 hp and sustain 20 hp reliably. I've sort of looked at FWD short axles and CV joints as a way to inboard the motors and keep the sprung weight down.

Commercially produced hub motors which people could slap on a wooden crate and drive off in is a long time fantasy of mine.

EDIT: Inspiration - if they could do it in 1900, why could not we do it in 2012?

The first Hybrid Vehicle
by Dr. Ferdinand Porsche

Jacob Lohner & Co in Vienna, Austria produced electric cars from 1898 to 1906.
Ferdinand Porsche, one of Lohner´s employees developed a drive system based on fitting an electric motor to each front wheel without transmissions (hub mounted).
Vehicles of this type were known as Lohner-Porsches.
