What is a slow speed corner?

Post

In motorsports, there is a lot of talk about slow, high-speed corners and power tracks, but what is slow? Are there fixed definitions?

Is a corner a slow corner if it´s driven:
Under a certain speed (<80km/h), because there are physical effects like particular aerodynamic parts only working probably to this speed?
or
at a specific gear to have a universal definition for everyone?
or
is it a thing everyone defines differently?

Same for high-speed corners and is a power track only defined by the amount of full throttle?

Just curious about definitions. I often heard the terms but never actually thought about how they are defined.

I always considered the corner to be a slow speed one if the performance around it was limited mainly by the traction during braking and acceleration. Fast corners for me are the one where the performance is limited by the lateral tyre grip and downforce if you have one. The actual speed depends on the kind of the car or bike.

In turns, the cars, of course, drop a little, but they still drive with monstrous numbers on speedometers: a turn at a speed of 100-120 km / h is considered “slow”, and with indicators of 160-180 km / h - “medium-speed”! There are also fast turns in which the speed reaches 250 km / h, and sometimes breaks through the mark of 300 km / h.

I like that one because it can be applied very universally, let me see if I got that right:

Simply put, a slow corner is one with a hard braking point (mechanical grip), whilst high-speed corners usually don´t have a braking point at all (just lift off - downforce if aerodynamics). Everything in between is a medium-speed corner.

This is the rule above applied to a specific era of Formula 1 car, isn´t it? I like the quote, do you know when he said that? I guess even for a specific race class the absolute speed would differ at least a little over the course of years?!?

There is no absolute limit between slow, medium and fast corners. There is no reason to define them either. It is only a mental and conversational aid.
I would like to see a paleontologist.

It is a conversational aid, but being on the same level in a conversation helps/can be crucial to avoiding misunderstandings, and that's what definitions are good for. That's why I like piast9's definition; it is universally applicable.

My question was if there is a clear definition, and it seems like you are right, the answer is no and that´s ok. :) Learning never stops. ;)
