The speed of the cars adjust to the speed of your racing. The faster you race, the faster the AI cars (bots) get and the slower you race, the slower the bots get. It is entirely possible to get bots that are better drivers than you and so you can't beat them even with a fully upgraded car. However, if you keep racing and losing, they will slow down. See link provided by RR3xyz for more detail on how to do it more efficiently. If you are a member of a team, the bots will be based on your team mates and will be a lot faster.
