Hi
Anyone know the power/economy for an E85 2.5i?

I've heard that anything over 2500 revs drinks petrol. That's around 60 mph in my 5 speed.
 
It probably is somewhere around that. Not so much because of the revs but because anything faster will generate far more aerodynamic drag.

I had the same engine in my 5 speed E46 325ti Compact and 70mph was about 3,000rpm in 5th. But over the 23K miles I did in it I averaged 32+mpg which seemed pretty good to me!

But your Z4 is a Sports car so why does economy even matter? :?

I only wish my Z4M was more economical because the fuel tank is so small!
