You like racing and you want to create a career out of it, but the problem is that you can't get your own sponsor. Fortunately, a guy offered you to become their driver. You were hesitant at first and tried to turn it down, but the guy told you that the pay would be huge, so you gladly accepted it.
Try to reach the finish line before time runs out. as you are driving, you will see some cash, repairs, boosters on the ground. All of them will be useful, so try to get them all. After finishing a level, you will get some reward money, which you can use to upgrade to use it later to buy a new and better car.
