Porsche Fuel Tank
In reading about the Miura one comes across many references to the fuel tank's location in the front causing the car to go light when there's less gar and thus lose some steering ability.
My question is this: Why don't I hear about this problem in 911s or Boxsters, new or old, since they have their tanks up front as well? Is it just a question of how far forward the tank in question is? |

I think the difference would be in the cars' aerodynamics, and avoiding front-end lift. The weight distribution issue would be similar.

I guess I have the same basic question regarding the DeLorean: front mounted fuel tank, and I don't believe (could be wrong) aerodynamic? Also, wouldn't using non-active aerodynamics still prevent the steering from being balanced regardless of fuel level?

To take a step back for a second "Loosing steering ability" is a pretty dramatic effect, typically you would experience this at very high speed due to front end lift and the tyres almost leaving the ground. More realistic at achievable speeds would be slightly reduced front end grip causing increased understeer. I have a Hillman Imp (also front fuel tank, rear engine) - people used to talk about carrying a bag of cement in the (front) boot to improve grip, with modern tyres the problem is not nearly so pronounced. You can only work with what you have got - eg tyre width and front/rear pressure differences, also brake balance. Hope this helps!

sorry to revive this old thread, but do standard Porsche fuel tanks contain safety foam?
