From the (much better) Reuters article [0]:> The higher the ratio, the more efficiently the engine works, producing better fuel economy and, with the addition of a turbo-charger, more power.> Traditionally, design engineers had to fix a gasoline engine's combustion compression ratio, essentially deciding whether to go for power or economy.Everything gets better with higher compression ratio, so where's the compromise? As I understand it, the only reason engine makers don't crank the ratio as high as possible is to avoid knocking.[0] http://www.reuters.com/article/us-autos-japan-nissan-engine-...
