I think one thing that seemed clear from Monaco was the lack of mechanical grip for McLaren.
It’s something that the top teams all seem to have under control- especially Mercedes since around 2013.
For the untrained such as myself- can anyone explain how you design a car to have improved mechanical grip? I see how McLaren are looking to improve their aerodynamics but is that not largely something that you see the benefit of at high speed? In the lower speed corners, what creates the so called “mechanical grip”?
And I guess then, why are Merc ,Ferrari and RBR strong in this regard?
Thanks
Well they haven’t made things easier by the extreme inboard pickup for the rear suspension pull rod. That choice means that the movement of the control elements, springs, dampers/inerter(s), will be less for any given wheel movement. This will amplify any errors in control.
It also means the forces at the ends of the pull rod will be higher requiring higher installation stiffness.
I'm no expert but at it's most basic it's all about keeping a biggest amount of tire on the ground under breaking and acceleration. That's easier when you're going straight but a challenge in curves, bumps, quick change of directions,etc. It's even a bigger challenge when, as Mansell89 pointed out, you start to manipulate the suspension for aero reasons.
This year is the 3ird time since 2014 that, I think, they've overhauled the rear suspension to get the more out of high rake.
