Here is the working condition link:
Good points. I would like to mention u that in this & above CLASSES it doesn't matter how much bigger the engine is. But HP rather makes the real difference among the rivals. It is no doubt that they all belongs to same calss. Rite? So it should be compaerd like this rather figuring out something else.
Let me give u a general example Koenigsegg CCX is 4.7L and infact twim suprer charged. But it is considered as a direct rival of Bugatti Veyron which is indeed 8.0L. They both belongs to same category performance wise.
And CCX is even faster from Murchillago 6.5L V12, enzos & SLR. No one points out this because it is obvious that CCX belongs to slightly upper class.
Same should be treated here.
Its up to u if u don't want to take the REAL FACTS.
