Vehicle Performance Index

Start the build with the right number.

Look up the base VPI assigned to a production vehicle. Then add fixed-point parts, non-fixed modifications, and swap points to determine the car’s total as-raced value.

Read the result correctly

Base VPI is not the final total

The current BCCR controls eligibility and penalties. These summaries help with initial planning only.

500 total points or less

No VPI penalty laps. Added components and swap points still count toward the finished total.

501 to 1000 total points

The car can compete in the standard ChampCar classes, but penalty laps apply under the current BCCR.

Over 1000 total points

The car is outside the standard podium limit. Review Exception Class eligibility and contact ChampCar before entering.

Factory forced induction

Factory turbocharged or supercharged vehicles add 100 points unless the VPI listing already identifies the value accordingly.

Vehicle age and factory models

The current BCCR limits VPI assignment for newer vehicles and generally uses standard factory offerings rather than unlisted special or custom editions.

Vehicle not listed?

Do not guess. Submit the make, model, and year through the Tech Desk before buying, building, or entering the car.

Before committing money: confirm the platform, proposed modifications, and any swap calculation against the current BCCR. A lookup result is not final tech approval.
