ok you just said a whole bunch of nothing. That doesn't tell anyone how they are determining who is first second 3rd
In other words they measure the brake horsepower and an estimate of the indicated horsepower (ie before losses). That's all you can do with the ICE.
so you think they just look at the max power output?
I have a few sources that tell me that yes, they look at peak power. If you combine multiple factors then % is a meaningless and inappropriate measure. How do you weight for multiple factors into a percentage? You cant, it would just be a score.
peak power is knuckle dragger level thinking though. An engine with a broader power curve but a slightly lower peak will almost always beat a motor with a higher peak (almost always comes with a narrow band).
A better way to do it is pick a minimum and maximum rpm range, and then integrate/calculate the area under the curve. The engine with the most area under the curve is almost always the better one.
You can do the same thing with torque curves.
they could do that across all the engine modes, and then come up with a weighting system that generates a single number. The higher the #, the better the engine is, then you calculate % difference from the engine that is currently the best.
