Isn't it the case that if it were purely a balance issue, then that could be achieved by any material, whether dense or less dense?

Because you want to reduce weight and not add more.

Sese, damn, no not that bad. What happened? At least you got it fixed already.

I agree
eg. for balance issue why not just thiken some metal at the front if the wight is too light at the front.
The problem is the other way around: the front would have been to heavy if steel would have been used (note: big heavy engine!) Of course we still want a sturdy front, so that's why they use a lighter material, aluminium.

Weight overall was also a consideration, so thickening some of the sheet metal would not be the best option.

Agreed. so it's a weight issue.

I don't disagree about the distribution of Al to genearlly lighten the vehicle, but I can't see how using the less dense Al in the rear (eg boot lid) is going to help balance the front/rear given the weight of the engine, gearbox and driver.

It seems counter-intuitive.

sorry not just talking about the e60. any car needs balance issue they can do that.
if the front is too light then put more metel on, if the back is to light then do the same, then the car can be 50/50 but easy say than done I know
