Big power without good brakes, chassis, suspension, tyres, lower weight and downforce means nothing. If you can hit 200 before corners but you can't slow down to the speed you go round them there is no point in having that power. Cornering speeds are the main differentiator round a track and why cars like the huracan, viper acr, ariel atom etc are ridiculously quick round tracks despite having relatively modest power (compared to similar times in far more powerful cars).

Look at F1 - where do the massive reductions in times come from? They can take corners at *absurd* speeds:

130R at 192mph/308kph at its slowest point (1:15) dropping  only 7kph from the top speed down the straight. Can other cars go faster down a straight? Absolutely, didn't even hit 200mph down the back straight.

Another cornering speed demo:

Which is more than [6g](https://youtu.be/OR5Tjfpi-Kg?t=51s) through that corner (6.5g in the mercedes, best car on the grid overall).

Cornering speeds are king. Slow down less, maintain higher speed through the corner and accelerate sooner out of it from that higher  speed.
