In NASCAR Heat 4, the cars go faster by using a “boost” system. This system is activated when the car is in a high speed corner and it gives the driver a small amount of speed. The boost can be used to help the driver get through corners quickly or to make a faster lap. There are three types of boost: “normal,” “medium,” and “high.” Normal boost is the most common and it works just like regular speed. It’s available to all drivers, but it’s less powerful than high boost. Medium boost is more powerful than normal boost and it only works for drivers who have high speed skills. It can help you get through corners quickly, but it’s not as powerful as high boost. High boost is the most powerful type of boosting and it only works for drivers who have very good speed skills. It can help you get through corners very quickly, but it also makes your car much more difficult to control.
