You have to go into their FAQs before you see any mention of a prototype and it's not very clear. As recent as September, they were spinning computer model tests as "Engine Reaches 65 MPG in Lab Tests", which is clearly meant to mislead anyone not willing to open the press release and read it through. Looks to me like they lack the funding to actually prototype this thing and now they're looking for an OEM to do the heavy lifting through their licensing program.

I was saying miller cycle before the video was half over. Mazda had an engine based on the miller cycle in one of their sedans. I think it was the millenia. The miller engine is a little more efficient than the standard otto cycle. What he doesnt talk about is the frictional loss and recipricating mass is double when compared to a standard otto 4-cycle.
The diesel cycle is 20% more efficient than both cycles. I do think direct injection will bring the otto cycle into the next 3 decades as one of the most cost and fuel efficient designs.
If they can only manage the emissions of a 2 stroke, that would take the cake!

The miller cycle engine are different primarily in valve timing- very late intake valve timing combined with supercharging in Mazda's case. I had a Millenia S years ago- impressive power and smoothness for small displacement, but also very eager fuel consumption. Wait a minute, that sounds a lot like Mazda's rotary engines too.
The Scuderia engine uses two cylinders to perform the work of one in a four stroke. It allows the intake stroke to occur simultaneously with the power stroke, which would give good power for a small combustion volume, and smooth power delivery at low rpm. I think rpm woul be really limited by the ability to mix the fuel/air charge enough to get even decent emissions. I think the valves on the crossover would take some creativity to build a durable seat and valve, especially since combustion is starting with one of those valves open.
