Hi Troy,
The other example of a very high MPG diesel is the Avion; elsewhere in these pages. He got 119MPG. The only diesel that gets better than that that I have heard of, is the latest VW 1L car, with it's electrical assist, ultra-light weight, and amazing low Cd. You'll need to model yours on the VW, I think?
