This engines is now in prototype form and has big players backing it, inc one large truck and engine maker and Bill Gates. They are VERY well funded and expect this engine to be as a hybrid range extender and with two modules in large vehicles. The clutch will give great fuel benefits without doubt. If they used the opposing cylinders on the same centre line using the Revetec cam lobes, no little end bearings are needed (simpler) and no piston side thrust. The inner pistons can be the same piston connected by rods, and the same with the outer pistons. The package will be much smaller. Efficiency will be improved. The electric turbo will benefit as it claws back wasted energy and gives the necessary pressure at all times. Overall I can see this engine about meeting the makers claims. Put the Revetec cam lobes on and it will shine.
