It's one year old news. The content is as vaporous as the fuel. What's today's news?
I have no personal interest in this web site but put it up to illustrate how this approach has been explored over and over.

If there are so many patents out there – current and expired – and the approach is viable, how is it that not one of the major auto makers are using it? Wouldn’t Toyota love to have four seater sedan with 100mpg in mass production? Japan especially would have an interest in gaining maximum fuel efficiency. Please don’t give me conspiracy theory. If it’s doable, then it would be done as a standard design feature by now and splashed all over the media. On the other hand, maybe it’s already being incorporated, but without the media splash. Auto fuel consumption figures have steadily been improving for ‘standard weight’ vehicles. It’s a no brainer that the fuel consumption of a really lightweight vehicle would be considerably less. It’s simply not credible that a backyard tinkerer has found the keys to the kingdom – again. Maybe there is something adverse about running an engine on a lean mixture for an extended period of time. One would have thought that whilst it might promote a complete burning, it would actually reduce engine efficiency.
Of course it’s been done before. In the years following WWII, Europe was flooded with three wheel, two cylinder engines, two seaters from auto manufacturers struggling with rebuilding capacity and with material and fuel shortages. Which is not to say that this won’t occur again. So maybe the idea of a lightweight two seater is simply ahead of it’s time.
