Thus, the sentence cannot say which IS an increase amounting to roughly five miles per gallon (in the present).
Eliminate E.

Hi GMATGuruNY, I doubt that "is" is the reason why E is not correct. Let us say:

Current fuel efficiency = 20 miles/gallon

The plan over the next five years is to increase it to 25 miles/gallon

Doing some quick calculation, 25 miles/gallon is 25% more than 20 miles/gallon.

The issue with E is the modifier "which", which is quite "far" from "25 percent", the noun it logically modifies. So, following would have been correct:

One automobile manufacturer has announced plans to increase the average fuel efficiency of its sport utility vehicles over the next five years by 25 percent, which is an increase amounting to roughly five miles per gallon, and represents the first significant change in the fuel efficiency of any class of passenger vehicle in almost two decades. [/u]
I agree that the placement of which next to the next five years (in E) is a valid reason to eliminate E. But the present tense in the revision above still creates confusion. Is takes amounting along for the ride, placing both actions in the present. A reader might wonder how an increase that is to take place over the next five years is amounting to roughly five miles per gallon right now. Since the increase is only planned -- and might not even happen -- the conditional would amount (in D) is better. We also can't say that 25 percent [the antecedent of which]...represents the first significant change in the fuel efficiency. The subject of represents needs to be an increase: an increase...that would represent the first significant change in the fuel efficiency.

C: an increase THAT would amount...and IT would represent
Here, that and it both refer to an increase.
Two different pronouns cannot have the same referent.
