Who says they are? On average no model year is overall faster then another. Some say the '90's are the fastest because they were the lightest. What it boils down to is engines vary. Just because it says 375hp or 405hp doesn't mean that is what the engine is truly putting out. You have some very strong 375hp cars and you have some weak 405hp cars.

The most significant and definitely the best change was the change of the main bearing caps on 1993-1995.
