There are a few ways to make a car wheelie in Forza Horizon 5. The first way is to use the drift function. To do this, you need to set up your drift settings and then start drifting. When you start drifting, the car will start to spin around and will eventually go into a wheelie. The second way is to use the boost function. To do this, you need to set up your boost settings and then start boosting. When you start boosting, the car will start to spin around and will eventually go into a wheelie. The third way is to use the nitro function. To do this, you need to set up your nitro settings and then start nitroing. When you start nitroing, the car will start spinning faster and will eventually go into a wheelie.
