Japanese giant OS have released the 19XZ-B engine under their racing OS Speed brand. A sort of ‘baby’ version of their popular .21 (3.49cc) engine the .19 (3.1cc) according to OS delivers a similar sort of power band that OS are known for; silky smooth. But one aspect that is greatly enhanced is fuel mileage. The racing engine market is a never ending battle of compromises of power and mileage, in this case it seems OS have offered up an engine that sacrifices a bit of power for big gains in fuel mileage, will it run a whole 45min final on one tank? Probably not but OS must feel confident enough that there is a gap in the market for such an engine…
