Washington will host a rare motorsports pairing next week when IndyCar takes to the city streets alongside the revived International Race of Champions, known as IROC. Organizers say IROC will serve as the lone support series for the Freedom 250 Grand Prix of Washington, an event framed this year as part of celebrations of 250 years of American independence.
Historic cars, familiar names
The IROC field scheduled for Washington comprises eight cars drawn from the historic IROC pool now in private hands. The series, which in its original form ended in 2006, has been revitalized as a popular historic championship in the United States. The machines are expected to be driven by a roster of established names from NASCAR and IndyCar history — drivers listed by the organizers include Jeff Gordon, Dario Franchitti, Kurt Busch and Hélio Castroneves — bringing a cross-discipline showcase to a downtown street course.

Roger Penske, who is the current owner of IndyCar, was also a founding figure in the original IROC series, which began as an exhibition format to pit star drivers from different disciplines in identical or closely matched cars. The Washington event will not replicate every detail of those earlier seasons: the cars available come from a collection acquired in 2024 by Ray Evernham, and organizers said the vehicles will come from that pool rather than being newly produced identical models.
Weekend scheduling and civic impact
Organizers have planned a reduced paddock footprint for the downtown layout to limit disruption to Washington traffic patterns, but the event will still change traffic, parking and pedestrian flows in areas near the course. According to published schedules, both IROC races are slated for Saturdays — the day before the main IndyCar Grand Prix events — making this the first time a championship under the IROC banner will run on Washington streets.
- Event: Freedom 250 Grand Prix of Washington
- Support series: International Race of Champions (IROC)
- IROC entries: Eight historic cars
- IROC races: Scheduled on Saturdays, day before IndyCar races
| Day | Series | Notes |
|---|---|---|
| Saturday | IROC | Two historic IROC races; support events for the Grand Prix |
| Sunday | IndyCar | Main Grand Prix events |
For Washington residents, the event presents both an unusual cultural offering and logistical considerations. Organizers said they have minimized the paddock footprint specifically to reduce the impact on traffic, but downtown road closures, modified public-transit routing and changes to pedestrian access near the course are still likely during the race weekend. Officials and event planners have typically issued neighborhood notices and detour information ahead of such events; residents should expect similar communications in the days leading up to the race.
What this means for motorsports and the city
Having IROC on the schedule gives the Washington race a historic angle: the series once operated as a high-profile exhibition that intentionally matched drivers across NASCAR and open-wheel fields. Its return to the capital as part of a special anniversary weekend underscores how organizers are positioning the Grand Prix of Washington as more than a single race — they are marketing it as a motorsports festival that draws well-known names and historic cars to the city.
At the same time, the use of historic machinery from a private collection rather than newly built, identical cars raises practical questions about parity and how closely the modern presentation will resemble the original IROC seasons. For fans and residents alike, the Washington stop will be a chance to see legendary drivers and cars in an urban setting not typically associated with top-level auto racing.
Event notices, schedules and traffic advisories are expected to be released by race organizers and local authorities this week. Residents are advised to monitor official city and event channels for up-to-date information on closures, public transit changes and access to downtown neighborhoods during the race weekend.
