Nascar cars are built according to regulations:

  • body length and KB – 5283 and 2794 mm
  • curb weight is at least 1542 kg, without driver and fuel – 1451 kg
  • engine capacity – 5,86 liters
  • power limitation – 865 hp
  • V8 with a 90-degree camber of the cylinder block
  • 4-speed manual transmission
  • torque – 718 n/m

Bolides tires are designed for quality grip and overcoming high and medium speeds. The construction of cars is done by partner plants: Ford, Chevrolet and Toyota, which supply (to date) only the cylinder blocks or hoods. The teams produce and tune the rest of the elements of the car themselves.

Nascar cars are equipped with carbureted engines with restrictors that limit maximum speed. In the braking system, which excludes a complete set of ABS-constructions, teams use air-cooled metal discs to which the flow of air comes through special ducts.

The basis of Nascar racing cars is a steel frame made of pipes, which protects the pilot during collisions. The front and rear frames of the cars are thinner than in the middle, which ensures an optimal absorption of energy from a possible impact.

The front spoiler adds stability and improves aerodynamics, while the rear serves to reduce pressure, there are no headlights or doors.

The Nascar driver’s seat is placed almost in the middle of the cabin and is equipped with six- or seven-point seat belts. While driving, riders experience sudden pressure changes and strong tensions in all muscle groups, which not every person or athlete can withstand. To create a comfortable environment, the Nascar pilot is provided with special diapers.
