Points are awarded in each class at the finish of each event. Team points. Team points are calculated in exactly the same way as driver points, using the point distribution chart. Each car entered is considered its own "team" regardless if it is a single entry or part of a two-car team. Manufacturer points
Circle of forces. The circle of forces, traction circle, friction circle, [1] or friction ellipse [2] [3] [4] is a useful way to think about the dynamic interaction between a vehicle's tire and the road surface. The diagram below shows the tire from above, so that the road surface lies in the xy-plane.
Other designs dramatically increase surface area to provide more traction than wheels can, for example in continuous track and half-track vehicles. [citation needed] A tank or similar tracked vehicle uses tracks to reduce the pressure on the areas of contact. A 70-ton M1A2 would sink to the point of high centering if it used round tires.
In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).
The 2025 schedule was released on August 29, 2024 and consists of 30 oval races, 5 road course races, one street track race, and 4 non-championship races to be held on ovals. [142] The start times were announced on November 13. [143] Notes: Race names and title sponsors are subject to change. Not all title sponsors/names of races have been ...
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...

Lateral force variation (LFV) is a property of a tire that characterizes its dynamic behavior of these forces. High values of LFV for a given tire reflect a high level of manufacturing variations in the tire structure that will impart ride disturbances into the vehicle in the lateral, or steering, direction.
