HSR, Pirelli announce multi-year partnership

Pirelli – a leader among global tire giants for more than 150 years – and Historic Sportscar Racing (HSR) have announced a new multi-year partnership that will see the leading Italian tire manufacturer become the official presenting partner of the new HSR Mission GT Challenge racing series.

Announced in HSR’s inaugural State of the Sport address back in September 2025, the HSR Mission GT Challenge presented by Pirelli features GT1, GT2, GT3 and GT4 race cars. Pirelli is the perfect fit for the all-GT championship as many of the eligible race cars in the series were campaigned in their competition primes on Pirelli.

“The HSR Mission GT Challenge is a new, prestigious championship that further strengthens our already extensive portfolio, which includes the world’s leading GT series," said Matteo Braga, Pirelli Circuit Activity Manager.

"In these programs, we see ourselves as full partners – more than a technical resource and far beyond a standard supplier. This is a new challenge, alongside highly professional organizers with very high expectations, and we will devote our full attention and effort to it. In the United States, we can rely on a close-knit, motivated team ready to provide first-class support and impeccable service, backed by a product that has already been extensively tested and widely appreciated.”

Mission GT Challenge presented by Pirelli aligns HSR's existing Group 9 and Group 10 categories that are generally home to production-based and GT race cars that were making modern-day motorsports headlines in the past two decades. Everything from home- and factory-built Single Make Series cars up to top-level GT machines just past their competition primes are welcome in the Mission GT Challenge.

The announcement includes the news that HSR Mission GT Challenge presented by Pirelli competitors will race exclusively on Pirelli tires commencing at the 48th HSR The Mitty, presented by Hagerty.

Starting in 2026, every HSR championship weekend features a full slate of Mission GT Challenge presented by Pirelli twin sprint races and a one-hour enduro, open to all eligible classes and cars in the series. Season-long points will be tabulated, including separate rankings for the enduro races, and Mission GT Challenge presented by Pirelli Champions will be crowned at the year-end awards celebration in 2026.

Next up on the 2026 HSR calendar of events is the 48th HSR The Mitty presented by Hagerty, April 23 – 26, at Michelin Raceway Road Atlanta.
