This is no wimp engine.
It's a two cylinder with four pistons delivering 300+ HP
It's extremely small and very efficient and is presently in use in test applications. The configuration below is equivalent to a extremely ballsy four cylinder engine. When doubled, it's an extremely ballsy 600+ HP engine.
It’s called OPOC (Opposed Piston Opposed Cylinder), and it’s a turbocharged two-stroke, two-cylinder, with four pistons, two in each cylinder, that will run on gasoline, diesel or ethanol. The two pistons, inside a single cylinder, pump toward and away from each other, thus allowing a cycle to be completed twice as quickly as a conventional engine while balancing its own loads.
The heavy lifting for this unconventional concept was performed Prof. Peter Hofbauer. During his 20 years at VW, Hofbauer headed up, among other things, development of VW’s first diesel engine and the VR6.
The OPOC has been in development for several years, and the company claims it’s 30 percent lighter, one quarter the size and achieves 50 percent better fuel economy than a conventional turbo diesel engine.
They’re predicting 100 MPG in a conventional car.

Just imagine going from a 20 something HP 4-stroke to a 300+ HP 2-stroke, and still getting 100+ MPG! Probably more, seeing you arent trying to move a 1 ton car down the road. Just a few hundred pound motorcycle. Obviously you'd have to watch it on the throttle though. Things tend to rip apart when it's not designed for that much power
