Bingo. Horsepower for weight would be more meaningful. Barring limits on displacement due to regulatory or taxation reasons, where they exist, if extra displacement comes at no cost to added weight ( and/or added bulk ) then whatever displacement increase available is all gravy. All that matters is power and it's ability to accelerate a vehicle: For it's size, a carpenter ant is many more times stronger than me, but there's no doubt I'll prevail in a one-on-one contest against it.
Another thing many seem to overlook is total available power and torque, and not just at the peak, but
the area under the curve as well.
