Interestingly, that engine has good power to weight ratio, has a better noise profile (higher pitched noise, that doesn't transmit far, albeit louder locally), can operate with a variety of fuels, and can handle arctic conditions. The downside is that it consumes 50% more fuel than a comparable diesel engine.
