Still, efficiency is good. It has been a lesser known fact that the standard multi piston engine model is hugely inefficient. Apparently this not only makes it more efficient fuel wise, but it makes it more efficient weight wise (20% less weight = 20% less energy wasted pushing it, not to mention cost and reliability)
> (20% less weight = 20% less energy wasted pushing it, not to mention cost and reliability)
Unless the weight of the competing engine is 20% of the weight of the car plus payload, reducing the weight of the engine can't get you to 20% less weight.
Also, cost and reliability don't necessarily go up as weight goes down.
