Making a #NASCAR Race Car: The Body
Most people think that NASCAR cars are built just like consumer cars, but they are actually much more industrial. The process begins with the original skeleton at Bill Davis Racing in High Point, North Carolina. The team didn’t build the frame from scratch. They buy prefabricated units from specialized suppliers. These aren’t just random piles of metal. These are engineered structures made of round and square steel tubes. The thickness varies depending on the position of the tube in the frame.
The most important part is around the driver. This is a roll cage. We use the thickest pipe available. Why? Because it must remain intact in the event of a collision. Its mission is simple: to keep the driver alive. Even if the car flips or rolls, this cage will absorb the impact without falling into the compartmentin.
The design changes outside the protected zone. The front and rear parts (called front clip and rear clip ) are made of thinner steel. This is not an omission. This is intentional. These clips are designed for crushing. When the car hits a wall or another car, these parts are deformed. It absorbs the energy transferred to the driver.
The front clip also serves another special purpose. Designed to push the engine out of the bottom of the car during a high-speed impact. The engineers wanted the engine to exit the vehicle instead of sliding into the compartment. This intrusion is lethal.
When the frame arrives at the shop, welding begins. Workers attach a firewall, a metal barrier that separating the engine compartment from the driver’s compartment. These are also welded to the floor panels. Next, install the mounting bracket. These little pieces of metal hold everything else together. engine. suspension. seat. fuel cell. Without these brackets, there is nowhere to bolt the components.
Then there is the body. This is where the magic happens. Almost all parts of the body are made by hand from flat sheet metal. The machine on the factory production line not stamped out. Carefully made.
