IROC's Resurgence
Through a partnership of Ray Evernham and Rob Kauffman, the IROC
trademark was revived to bring one of the most exciting series back
to the forefront. With many of the former IROC race cars
race-prepped by Ray Evernham Enterprises, these cars spanning from
1973 to 2006 are ready to be back on a track and used in the way
they were designed to be. The 2025 Rolex Monterey Motorsports
Reunion inaugural IROC racing class represents a rare opportunity
to race alongside racing legends and those who raced the same cars
in the original IROC series. These include Jeff Gordon, Danny
Sullivan, Mark Martin, Bill Elliott, Ken Schrader, Bobby Labonte,
Scott Pruett, Zak Brown, Bruce Canepa, and others.
The Quail, A Motorsports Gathering, will be hosting the IROC race
cars as the Featured Racing Class on Friday August 15th, 2025 at
the Quail Lodge, complete with a police escort from Laguna Seca
through the mountains of Carmel Valley. With Rolex Monterey
Motorsports Reunion signing on for 3 years of IROC racing classes
just to start, the IROC racing series is seeing a resurgence unlike
anything else, with a driver's opportunity to racing among other
racing legends and celebrities.
2005 Pontiac Firebird IROC
The International Race of Champions (IROC), an American racing
series promoted as the equivalent of an all-star game, was a unique
and prestigious motorsport competition that ran for several
decades, from 1974 to 2006. The goal was to bring together the best
drivers from various driving series to compete in
identically-prepared cars at some of the world's most legendary
tracks. With names racing such as Can-Am and Trans-Am champion Mark
Donohue, F1 champion James Hunt, NASCAR legend and champion Dale
Earnhardt, Indycar champion A.J.Foyt, Trans-Am, Can-Am champion
George Follmer, and more legendary drivers were invited to join the
racing championship to prove who was the best of the best.
The IROC series was founded in 1973 by Roger Penske, Les Richter,
and Mike Phelps, wanting to create a championship that featured top
drivers from a variety of racing categories and disciplines, such
as Formula 1, IndyCar, NASCAR, and sports car racing. The goal? To
create a series to determine the "champion of champions" by placing
competitors in identically-prepared cars to level the field across
the board. No secret additions, no extra power, no trick tuning,
just pure raw driving ability. Still remembered as a unique and
prestigious series that brought together some of the greatest
drivers in motorsport, IROC created the concept of identifying the
"champion of champions" and cemented it as a memorable era of
racing history.
While the IROC concept seemed simple enough in theory, the
implementation was slightly more difficult, especially when
bringing together 12 top drivers and preparing 12 identical cars
(with 3 additional spare cars) with equal performance in all
aspects. Debuting in 1973 with Roger Penske, the series organizer,
and the late Mark Donohue, the project supervisor and development
driver, found their first cars with the help of their German
counterparts. Porsche Carrera RSRs were the first cars used in the
series and the first season was met with popular reception.
However, there was a snag: the Porsches proved to be too expensive
to build and maintain, and a suitable replacement was needed.
Penske, with his ties to Chevrolet, found the next logical choice
in the form of the 1974 Chevrolet Camaro. Fast and inexpensive to
acquire and modify, the Camaro would end up being the platform of
choice for the next 15 years.
Fast forward to 1996 where IROC introduced the Pontiac Firebird as
the next iteration of race car for the series, raced through the
series conclusion in 2006 and were designed by Laughlin Racing.
This 2005 Pontiac Firebird IROC car is one of the final examples
ever built and only competed on track during the 2005 and 2006
seasons. Only 4 lucky drivers piloted this chassis with its most
recognizable appearance in the final 2005 season race with Mark
Martin, finishing in 2nd place at Atlanta and clinching his 5th
IROC championship. Helio Castroneves accompanied Sam Hornish Jr.
and Max Papis as the other racers who drove #LRP5374 in
competition, with Hornish Jr. taking 2nd place at Daytona in 2006.
Equipped with a 350 C.I.D. engine with 500 horsepower, paired to a
Jerico 4-speed manual transmission, Winters Quick Change
Differential, Brembo Carbon Vented Disc Brakes, and power steering,
the Firebird is a potent historic racing package.
In August of 2025, Rolex Monterey Motorsports Reunion will play
host to a special IROC class of racing, featuring legendary IROC
competitors, modern racing legends, and displays of over 20
historic IROC cars. This #03 2005 Pontiac Firebird IROC has been
race prepped by Ray Evernham Enterprises, IROC co-owner, is in
restored condition and is eligible for this year's 2025 Rolex
Monterey Motorsports Reunion, future IROC series classes, along
with other historic race events nationwide.
The IROC series represented a unique and special snapshot in racing
history, gathering the best of the best to compete against one
another on equal footing. Seeing F1 champions race against Indy car
champions, along with NASCAR drivers rubbing against sports car
drivers. A series as unique as IROC may never take place again, but
with this race-ready #03 Pontiac Firebird you can drive and enjoy a
piece of motorsport history.
