The International Motor Sports Association (IMSA) has acquired the Historic Sportscar Racing (HSR) series.
HSR is known for its vintage and historic sports car racing, including its trio of HSR Classics events at Daytona International Speedway and Sebring International Raceway, plus its HSR Mitty event at Michelin Raceway Road Atlanta.
“Bringing HSR into the IMSA family substantially strengthens the links to previous generations of sports car racing, from eras that predate IMSA all the way through to cars that have competed in the IMSA WeatherTech SportsCar Championship,” said IMSA President John Doonan.
The 2022 HSR season opens with the annual Spring Fling at Sebring on April 6–8.
HSR becomes the eighth racing series to be sanctioned by IMSA, joining the WeatherTech Championship, IMSA Michelin Pilot Challenge, IMSA Prototype Challenge, and its four single-make series: Ferrari Challenge North America, Idemitsu Mazda MX-5 Cup presented by BFGoodrich Tires, Lamborghini Super Trofeo North America, and Porsche Carrera Cup North America.
