I'm doing something in Gran Turismo 4. Since I am lazy, I used a Gameshark to unlock all the cars in Gran Turismo 4 and to also get 1 trillion credits(Thanks, Gameshark!). Then I asked myself: "Self, which car in the game is the fastest down a 1/4 drag strip?" So, I'm finding out by running cars down the Las Vegas 0-400m(or 1/4 mile) track. I have only three requirements:

1. The car must be a race car of some sort
2. The car must be a rally car of some sort
OR
3. The car must be a street car with at least 400 Horsepower.

After I run every car, I will take the ten fastest cars and run them in a series of three final rounds:

Round 1: Top 8 advance
Round 2: Top 5 advance
Final Round: Winner take all

I'll update when I get a top 10.
