But for measuring the performance of the engine, hp/L is inappropriate. It simply fails to measure anything of value. If it were possible to build an engine with twice the displacement but the same weight and form factor as another engine with the same power, those engines would have the same performance; the hp/L measure would show the larger-displacement engine as having half the performance.

Notice a continued denial without a single example, cited trend, engineering principa, or supporting fact. Russotto would have you believe that since a 2 liter engine and a 5 liter engine both output the same horsepower, then both are equal performance. That is silly. The higher performance 2 liter engine also weights less, occupies less space, is more reliable, and is quieter.

FINALLY, FINALLY, you hit on something valid. Yes, IF the 2-liter engine weighs less, it could be said to have higher performance. Weight of the engine has a direct impact on performance of the vehicle it is put in. Displacement doesn't. Volume does, but the relationship isn't nearly as simple as with weight. Reliability and noise are issues separate from performance -- those high perfomance engines in race cars are extremely noisy and very unreliable, for example.
