In 2017, ChumpCar World Series adopted the name ChampCar Endurance Series and filed for trademark rights after receiving the blessings from the IRL to use the name. A registered trademark was granted by the USPTO on August 28, 2018. ChumpCar World Series, a budget class endurance racing organization known as ChumpCar International Inc., was founded in 2009. Chumpcar was a play on words named after the defunct Champ Car World Series. The initial concept was an endurance racing series for cars of $500 in value or less similar to the 24 Hours of LeMons endurance racing series. In 2015, ChumpCar Canada was split off as a separate entity, although there is still close coordination between the US ChampCar Endurance Series and the Canadian ChumpCar organization. ChumpCar World Series began referring to itself as ChampCar Endurance Series in November 2017.
Preparation and rules
To enter an event, competitors are required to select a vehicle from the Vehicle Performance Index list of cars located on the ChampCar website. Vehicles are listed with point values based on the stock vehicle's performance potential assigned to each model year. The table contains a large variety of makes and models to choose from. If the point value of the vehicle is less than 500, additional points may be spent on performance parts, as long as the total point calculation of vehicle plus performance parts does not exceed 500. This point calculation excludes required safety equipment, as well as maintenance and replacement of wear items with OEM or OEM-equivalent parts. No credit is given toward the point calculation of the vehicle for selling removed parts. Vehicles with a point calculation in excess of 500 are allowed to compete with penalty laps subtracted from their total. While the assessed vehicle point goal is 500, typical actual build costs can run anywhere from $4,000 to $10,000 to prep a car. Most of this budget is safety related such as brakes, roll cage, tires, racing seat, fire suppression system, and fuel cell. The races run for a fixed length of time. The team that completes the most laps net of penalty laps is the winner. The event organizers impose a complete set of safety rules that typically are on par with other road racing sanctioning bodies, including the Sports Car Club of America and National Auto Sport Association. Tires are restricted to a UTQGtreadwear rating of 180 or greater. Prior to July 2013, this value was 190. The change was made to allow for additional options in tire selection.
Race format
Events are held at major road racing tracks across the US. The most common event format is a two-race weekend, with one eight-hour race each on Saturday and Sunday. However, a variety of other formats are used, with lengths ranging from 10 to 24-hours. Starts are picked by a random number generator utilizing the pit stall number. The order is reversed for the following days' race. Teams are scored and ranked by the number of laps completed during the time allotted for the race net of penalty laps. Teams are required to include at least two drivers. Each driver is required to complete at least one hour in the car. No stint is allowed to exceed two hours, with a minimum one hour rest. Pit stops where fuel is added to the car are required to be at least five minutes in length to ensure safe refueling.
Awards
The top three finishers on laps in each race are recognized with a trophy and a credit toward future participation in the series. Top finishing teams are awarded "Race Credits" for discounts to future races. Additional awards may be given for notably good driving, especially dedicated repair work, or good overall spirit. Overall spirit is specially recognized by the Spirit of ChampCar Award, given to the team in the race that the organizers feel best exemplifies the competitive spirit of the series.
