Safety Features

The valence has been replaced with a splitter made of fiber fortified plastic. Located at the bottom front, it is used to generate downforce. The fuel capacity is less; from 22 gallons, it has been reduced to 17 ½ gallons. However, the fuel cell is now sturdier. The exhaust system has also been improved so the heat is not directed at the driver.

Other innovations include a detached wing and a windshield that is more erect. This is intended to create more drag. The radiator is under the front bumper. The purpose is to prevent overheating due to blocked grilles.

The bumper has also been redesigned. With its box like shape, it will take in more air and reduce the car’s speed.

The NASCAR car dimensions and specifications are subject to constant reviews. This means the features of the car style may be revised or altered.
