understanding how the car handles is not the same as being a mechanic.

That's your definition. Who is it then that adjusts wheel alignment settings, suspension settings, wings, tire pressure adjustment etc ..

nospam
mechanics.

Actually, the pit crew is a team of specialists. Generally, when we use the word "mechanic", we are referring to a person who works on or repairs the drive train of a vehicle...engine and transmission. The pit crew people specialize in adjustments to the vehicle, fueling, and tire changing. While they probably have some mechanical skills, the real "mechanics" are back in the garage. I doubt if any race driver refers to his pit crew as his "mechanics".

nospam
unimportant distinction.

the point is that it's not the driver who does it.

Eric Stevens
It's usually the driver who decides it.

Savageduck
Perhaps in days past, and perhaps in races other than F1, F2, IndyCar, GT1, & GT3.

Today in F1 the car is a mass of telemetry sending data from hundreds of sensors to the pits where a team of engineers sitting in front of a wall of monitors evaluate what needs adjustment and what need to be adjusted in the car by the driver and passes on to the pit crew and those "mechanics" what they need to prepare to fix or adjust on a pit stop. It is those engineers who tell the driver what they need him to adjust in the car on that complex steering wheel. Those sensors tell them stuff such as the pressure in the push-rod suspension on each of the corners, with that they can make balance adjustments to wings, suspension etc. They get feedback on brake temperatures, exhaust temperatures, fuel flow, KERS charge, KERS discharge, and so much more.

Eric Stevens
That's all trimming of what is already there. What is there and how it is set has been decided by previous testing and driver input. The car which races at Monaco is not the same as the car which races at Monza.

Savageduck
No kidding!

Eric Stevens
And why should that be?

Savageduck
Are you sure you follow F1?

The cars are usually the same car but with different set up, for the different tracks. Monaco being a relatively slow street circuit and Monza one of the fastest tracks in F1.

Eric Stevens
Maybe the same shell.

Possibly not the same engine characteristics (though I don't know the current regs),

suspension settings will be different,

so too will be gear ratios,

the aerodynamics will be at opposite ends of the spectrum,

tires will be different,

steering will (probably) be different: otherwise the cars are identical.

Savageduck
Monaco has slower speeds, fewer passing opportunities, very tight corners, and a bigger elevation changes than found at some of the new circuits. Monza has high corner approach speeds (as high as 210 MPH) and short braking areas putting heavy loads on brakes. The wing settings at Monza are usually set at minimal angles to reduce drag on the high speed stretches. Lap speed record at Monza is 162 MPH. Contrast that with Monaco where the record on the current circuit configuration is 113.3 MPH. Two very different tracks, two very different set ups.

Eric Stevens
Exactly. So the mechanics cannot (as per nospam) setup the car without major input from a knowledgeable driver.
