Acceleration is less than the Tesla, but the cornering ability is probably a lot higher.

The use of vaporized fuel is interesting because it's the same technique used by all those semi-mythical 100 MPG (or 200 MPG!) carburetors in the past. I say semi-mythical because they always really existed but never really produced the kind of results that were claimed. The efficiency gains from bolting one of those vapor systems onto an ordinary engine, in an ordinary car, wasn't significant.

For maximum efficiency a three-wheeled vehicle is hard to beat, and the handling performance can also be very good. This is why the Silence is going to smoke the Tesla Roadster and possibly even beat the Wrightspeed X1 on a race track.

From the article:

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.

I'm not sure what's impressive about that, since catalytic converters have nothing to do with CO2 emissions. To be sold and driven on public roads it will need a catalytic converter, and that will reduce its efficiency. (But not much, because today's catalytic converters are quite good.)
