the above two phrases with the term "grip" are plain stupid talk.Espresso wrote: ↑Thu Apr 04, 2019 9:30 amI always thought:ispano6 wrote: ↑Thu Apr 04, 2019 4:22 amTraction and drivability are the terms Formula engineers and mechanics use. Not "mechanical grip" or some silly term that makes no sense. Drivability is the ability to modulate power delivery of the drivetrain in a way that suits the drivers style and is congruent and predictable with the given pedal input.diffuser wrote: ↑Wed Apr 03, 2019 3:00 pm
There is one of those made up terms, Drive-ability. What does that even mean???? Do they get amazing starts from it? no, they are average so far this, at best. Do they have less wheel spin because of it? no. Less tire consumption? No.
It was something that in the early years of the new PU regs meant something but now means nothing.
Driveability = the degree of smoothness and steadiness of acceleration of an automotive vehicle -or- (F1 specific) how good the car suits the driving style of the pilot.
Mechanical grip = The resistance between tire and surface resulting in the amount of traction a car can transfer.
Aerodynamical grip = Stability of the car in the airflow.
when people say mechanical grip they mean to say traction.
I've never heard of aerodynamic grip. In aerodynamics there is downforce, drag, resistance, dirty air, and wake. There is no such thing as air grip. There is surface tension, coefficient of friction etc. To call it aerodynamic grip is a misuse of diction.
Listen to Toto Wolff or the drivers, they always mention drivability, traction, and balance.
