Maybe a silly question.. but what is the benefit of underrating engine numbers and performance figures?

Basically, the benefit for any manufacturer is to cover their ass. If they rated their cars at the exact HP and performance numbers, there is bound to be some owners and reviewers/testers who may not be able to achieve those numbers on a dyno or at the track. There could be many variables why exact numbers may not be reached during a given test, so manufacturers will give themselves a safety cushion with underrated numbers.
