A car that makes its peak tq from 2000-5500 RPM such as my old 335, had great acceleration at any given RPM but peak power came around 6000rpm even though it redlined at 7k. It was great on low speed races but it was not once you stay get to speeds (higher rev range). The perfect example is the AMG cars VS M5. AMG cars are faster at lower speeds but the M5 smokes most of them anything over 120mph. Why? Because it accelerates for longer period of time with its higher redline. Same example can be used with s2k vs other cars that had twice the tq such as the z33 also ferraris vs lambos. Every manufacturer has its own way of building an engine, its just a matter preference what you are into. Me higher redline and higher peak hp > than bunch of tq and lower rpm peak power.

Both are very important and depend on each other. The thing that will not change is that higher RPM peak power = less tq and vice versa. Again TQ wins races is not an accurate statement.
