I know the video is just a marketing aid, but the way they present the information is not quite within the laws of physics. For instance, it shows them turning off the compression cylinder with a valve in between the two cylinders. While this does in effect shut off the flow between the cylinders, it does not reduce the drag on the engine like they say. That would require a valve that opens the port to the outside such that no compression takes place. As shown, it would just compress and uncompress whatever air is left in the cylinder. I suspect, this may just be poor animation though.

Another thing that jumps out at me is at the end when they talk about adding a turbo to capture lost power to help reduce the drag of the compression cylinder. Yes what they say is technically true, it will give you more power, it will also give you less fuel mileage. If you take a standard ICE with X hp and Y MPG and add a turbo; you will have an engine with X+Z hp and Y-W MPG. Where Z is the power gained from the turbo and W is the load to the engine.

There are some real pluses to this design. By doing a pre-compression on the fuel air mixture, you would get a very complete burn of the fuel. Also, the regenerative system (if built correctly) would be a real advantage in city driving.

I am, of course, not saying that this isn't viable, but I would need to see some real world numbers before I believe that any of this is more efficient than a simple ICE. Running a compressor the same size as the combustion chamber is going to produce an incredible amount of drag on the engine. I suspect that with the regenerative braking it would be more efficient in city driving than compared to on the highway. But only comparing it to itself. As far as this being more fuel efficient? Call me a sceptic. I have trouble believing; without some hard numbers to back it up.
