Wait, the cars must be wheel powered, but can we use applyForce to spin the wheels?
wheel powered. it doesn't matter what method you use to spin them.
the cars are looking real nice, glad to see people are participating. :)
Edited:
i just had an idea! I didn't know so many were going to compete, so I had the idea of setting this up like a tournament, but it's up to you guys.
Basically, it'll work on a duel basis. Two competitors will be pitted against one another, and the one with the lowest overall time advances, the loser does not. This might make it easier to manage all of the times. Say Shogoll goes vs Sestze, and Sestze has a lower time for the up and down run of gm_rallye & rallye_snowe, Sestze wins the round, and Sestze will advance to the next round while Shogoll is eliminated.
Here's an example:

An elimination, if you will.
