Ben and his friends wanted to know who is the fastest, it means that they would drive vehicles since none of them XLR8 and that is unfair match for all of them, except for XLR8, of course. They have decided that they would be using some sort of transportation to determine this. They all agree to use a truck since it is massive and won't easily get top speed. They won't have any problem when climbing some mountain. At least, truck would be fair as no one can rival XLR8 when it comes to speed. It won't be a fair match, but a truck race would give them some hope of winning.
In this game, you need to drive your truck as fast as you can till you reach the finish line. There are no second spot in this game as you need to be the first to reach the finish line. You can collect some skills pint, which you can use to upgrade your truck later. Then again, this game is about understanding about dynamics of the truck, so you need to use that to your advantage. Anyway, if you can't win, you just need to collect some skills points to be able to buy some upgrade.
