- Buggati veyron has a spoiler system. It activates when you are slowing down (breaking). So imagine you are over 400km/h in Buggati veyron, and if you hit the break, the spoiler will come out and help you to stop the vehicle. (The spoiler doesn’t come out when you are going back)
OR
- You can put out the spoiler anytime you want by pressing a button.
