Gearing on 86 4000 quattro sedan

[selick@cs-mail.bu.edu (Steven Selick)]

Why did they gear the 86 4000 quattro sedan so low? At 120 mph 
the revs are already well near 6000, and it would seem that it
wastes gas. I have an 84 non quattro coupe that I am selling,
and it has a similar 1st, 2nd, and third, but 4, and especially
5 on the coupe offer a lot more leway. I think it is at about
5000 rpm at 120 mph. 

Is there any simple mod to lower the highway revs in 5th gear?
