Anatomy of a NASCAR Racecar

Anatomy of a NASCAR Racecar


Ever wonder what NASCAR fans and broadcasters are talking about when mentioning different sections, pieces and parts of a NASCAR Sprint Cup Series car?

Front Splitter: Allows teams to tune the front downforce to individual drivers and tracks.

Brake Air Intake: Directs outside air to brake discs and rotors for additional cooling.

Radiator Air Intake: Directs outside air into the radiator to cool engine fluids.

Body Panels: Fabricated from 24-guage/0.0247-inch (minimum) cold-rolled sheet metal.

Hood Pins: Four, quick-release metal pins with wire tethers that keep the hood closed.

Cowl Induction: Housing for the air cleaner that connects the air intake at the base of the winshield to the carburetor.

Jack Post: Area where the jackman places the jack to lift the car during pit stops.

Roll Cage: A cage of steel tubing inside the car that protects the driver during impacts and rollovers.

Windshield Clips: Allow for easy removal of the windshield should a driver need to be extricated from the car.

Double Frame Rail and Energy Absorbing Material: A combination of steel plating and energy absorbing materials installed in between the roll cage door bars and door panels that attenuate upon impact.

Window Net: Safety device located in the driver-side window that keeps the driver's head and arms inside the car during an accident.

TV Camera: Allows NASCAR fans to view the racing from the driver's perspective.

Roof Strips: Two half-inch-tall aluminum strips which run lengthwise on the roof to help prevent the car from flipping when turned sideways during a spin or accident.

Alternate Exit: Also known as a "roof hatch," it allows drivers to exit the car in the event of an emergency situation.

Roof Flaps: Help prevent the car from becoming airborne when it is turned sideways or backwards during a spin or accident.

Cooling Vents: Help remove warm air from the cockpit.

Goodyear Eagle Racing Tires: Treadless radial tires designed specifically for racing.

Jacking Bolt: Area where the crew uses a tool to adjust the handling of the car by altering the pressure of the rear springs.

Adjustable Rear Wing: Directs air flowing over the rear of the car, providing better balance and control in traffic.

Dry Break Fuel Cell: Holds 17.75 gallons of Sunoco racing fuel inside a protective, puncture-resistant bladder.
