ChampCar Rules Philosophy
ChampCar Endurance Series rules are designed with one main goal: make road racing accessible to more people without turning it into a spending contest.
Many racing series control competition by adding more classes, more restrictions, more required parts, or more expensive compliance systems. ChampCar takes a different approach.
We use a value-based rules system that allows a wide range of cars to race together while keeping the focus on safety, reliability, preparation, strategy, and driver skill.
Our rules are not written to create the most expensive race cars. They are written to create the best racing.
ChampCar is built around affordable, production-based endurance racing. Teams can start with common street cars, prepare them for safety, and build within a rules structure that rewards smart choices instead of unlimited budgets.
Rather than forcing every team into a narrow spec build, ChampCar allows creativity. Teams can improve their cars, but performance upgrades are balanced through points, starting laps, classing, and race strategy.
ChampCar rules help keep costs down by focusing on value, not checkbook racing. Teams choose where to spend their budget, and smart preparation can matter just as much as horsepower.
Multiclass Racing
ChampCar uses multiclass racing to make competition accessible to more teams and more types of cars. Not every car needs to be the fastest car on track to have a race worth winning.
A lower-powered car can still fight for a class win. A higher-powered car may have more speed, but it also has more fuel use, tire wear, brake wear, and risk. Endurance racing rewards the complete package.
ChampCar’s point system helps balance different cars and different levels of modification.
Each car starts with a Vehicle Performance Index, or VPI. Teams can make modifications, but many performance upgrades add points. If a car exceeds the allowed point total, it may start the race with penalty laps.
This allows teams to make choices. You can build a simple car with fewer points, or you can add performance and accept the consequences.
Racing is never cheap. But ChampCar works to keep the door open for regular people, small teams, family teams, first-time builders, and grassroots racers.
The goal is not to remove competition. The goal is to make competition possible.
Whether you are building your first race car or bringing years of experience to the paddock, ChampCar gives you a place to race hard, learn, improve, and compete.
