It's running a
turbo-powered honda engine. I wouldn't say it's awkwardly cobbled together. It's much easier to utilize something that someone else has already engineered than to create something completely new. It also allows them to use aftermarket components (ie adjustable coilover suspension) made to work with the 'borrowed' parts.
As for the emissions being excessive at such a high AFR, quite the contrary. The most extraordinary aspect of this vehicle is the fact that its engine is powered by petrol vapor rather than liquid. Vapor is a completely different beast than liquid.

The “alé” runs on regular gasoline, and easily achieves the level of “super low” emissions with a 30% reduction in CO2. Even more impressive is the fact that all the data to date has been gathered without a catalytic converter.

Most of the harmful emissions produced by engines are the result of incomplete combustion. Under normal conditions, Nitrogen and Oxygen won't form a bond, but high heat provides enough energy to change that. Must of the fuel injected into a liquid petrol burning engine does not produce any power, but rather quenches the cylinder. This is where production of harmful emission occurs.
Vapor allows for more complete combustion for several reasons (I can go into these upon request).
