Built on a Courage C65 chassis and powered by a 450-bhp three-rotor
rotary engine, this ethanol (E100) powered concept was reported to be
running very quick lap times at Laguna Seca.

Dang that is an ugly car :) The aerodynamics sucks as well.

Why only 450 HP? Using Lemans engine p-port tech it should
be around 525 HP

Of course it is going fast. The wing is illegal for any class
of road racing I am aware of :) Laguna Seca is a downforce track.

BTW I finally got around to scanning that 3rd gen difference data
you sent me a couple of years ago. Thanks for that. The subject seems
to be coming up again.
