The International Race of Champions (IROC) series was a unique and prestigious motorsport
competition that ran for several decades, aiming to bring together the best drivers from various
racing disciplines to compete in identically-prepared cars at some of the world’s most legendary
race tracks.
The IROC series was founded in 1973 by Roger Penske, Les Richter, and Mike Phelps. The idea
was to create a championship that featured top drivers from different racing disciplines, such as
NASCAR, IndyCar, Formula 1, and sports car racing. The goal was to determine the "champion of
champions" by placing competitors in identical race cars.
IROC is remembered as a unique and prestigious series that brought together some of the
greatest drivers in motorsport. The concept of identifying the "champion of champions" remains
a memorable aspect of racing history.
The Pontiac Firebird IROC was introduced in 1996 and raced through to the series conclusion in
2006. The IROC Firebirds were designed by Laughlin Racing.
Cars would be identically painted in white, with trim which could be changed to represent the
driver's colors in his regular racing series. Also, a driver's number in IROC would be the same
number they used in their primary racing series. The only exception to the numbering scheme
involved the number 3. Following the death of Dale Earnhardt in the 2001 Daytona 500, IROC
retired the use of No. 3. Any driver with that regular number would use No. 03 instead. As seen in
this example, Hélio Castroneves raced with No. 03 when he drove this car at Texas Motor
Speedway in 2005.
This car was one of the last IROC Firebirds ever built and only competed on track during the 2005
and 2006 seasons. Only four drivers ever got behind the wheel of this car in IROC competition
with the most notable appearance coming in the final race of the 2005 season with Mark Martin
piloting the car to a second place finish, which locked up his final and record setting fifth IROC
championship. Sam Hornish Jr. and Max Papis join Martin and Castroneves as the other two
drivers to pilot chassis # LRP 5374 in IROC competition.
