The reason you should care about hp/l is not for the performance it gives you in your car but because it is a challenge of extremely difficult engineering. It is simply doing more with less which is univerally valued in just about any endevour. In competitive auto racing where you have a displacement limit this is obviously the key to a great engine at a given displacement.

OK, tax regs are important in some countries, but in regard to engineering, I have this feeling that if you were in your Z06-powered M3 against my stock M3, blowing exhaust in my face as you ran away from me, your top thought wouldn't be: "Yeah, I'm killing him, but
his car was more difficult to engineer.
Damn!"
