Gary Anderson (néhény napja publikált Autosport Plus cikk):
Going into other regulation change, the fuel tank size is bigger. It will add about 20 centimetres to the length of the car if you just cater for a bigger fuel tank. And that has lots of implications for weight distribution and the general centre of gravity of the car, which you need to take into account.
Regarding the design of the tanks, there is a bit of a trade-off in height. You cannot really go stupidly high because of the way the aerodynamics works. The top of the head rest area automatically gives you a top of where you can put the fuel tank to.
If you imagine the centre of gravity of these cars is 15cm up from the bottom of the car, then fuel up to that height lowers the centre of gravity, because it is below the COG. After you go above it, it starts to raise it. So there is a point where the car changes its characteristics – slowly, but reasonably dramatically, because of the COG height.
So you don't want to go stupidly high with it for either mechanical or aerodynamic reasons. The width of the fuel tank is defined in the regulations.
És Gary Anderson is utal az üzemanyaggal való súlyelosztás-szabályozásra:
The fuel tank size is big enough, once you have used a bit of fuel, to affect weight distribution by trying to trap the fuel, either forward in the tank or rearward in the tank. You can affect the weight distribution at, say, two-thirds race distance by baffling the fuel in the tank and controlling it in the area that you want it to be controlled.
