If you go to a car race, you’ll notice the cars rev like crazy at the start. Internal combustion engines have no power unless you rev the crap out of them. What sounds like glorious grunt is actually a compensation for a hopeless technology. Also the reason they rev the cars when down-shifting as well as up-shifting, to try to keep the engine providing power. The mistake is to think the noise = grunt. It actually means the reverse.
