Hi first post here,
IMO, the biggest problems facing combustion engines are the energy losses associated with them (or inefficiencies, rather). Were all familiar with what they are. Modern engines have been worked on and tuned to a point now, where they're basically as good as they're going to get. So unless this engine offers a way to combat these losses, I'm reluctant to believe reconfiguring the cylinders will cause a revolution.
Looking at the engine and its peak torque being measured at 800rpm, I would hazard a guess and say these engines will inherently always have a low rpm and hence struggle to output desired power and require larger than normal gearboxes to accommodate.
