I was thinking something like what the Blackjack Zero uses might fit (with it's Weber carb laid back over the transaxle), but it's really not much lower than a Porsche/Subaru boxer.
A lot shorter though. Hey, the Urbee is a reverse trike, how about this (scaled down)?

I've been thinking about doing this to my Beetle, but in Lexan since Studebaker glass would be expensive.
