– The 901 Shop Wins a Record Three of Four Competing Run Groups at the First Season-Opening HSR Sebring Classic 12 Hour Presented by Mission Foods
– HSR Sebring Classic 12 Hour Presented by Mission Foods Kicked Off Two-Week Sports Car Racing Celebration Leading into This Weekend’s 73rd Mobil 1 Twelve Hours of Sebring
SEBRING, Florida (March 14, 2025) – A record entry for last weekend’s Historic Sportscar Racing (HSR) Classic Sebring 12 Hour presented by Mission Foods delivered record race results at Sebring International Raceway.
Contributing to the stout entry list of more than 260 competitors – a record for a season-opening HSR event at Sebring – was the move by HSR and Sebring officials to make the HSR Sebring Classic 12 Hour presented by Mission Foods the lead-in to this weekend’s 73rd running of the Mobil 1 Twelve Hours of Sebring. Since its introduction in 2016, the Sebring Classic 12 has closed the HSR season each December, but the schedule shift created a two-week motorsports celebration that is sports car racing heaven for fans and competitors alike through Saturday.
The Classic Sebring opener was the first event in the inaugural season of the HSR Classic Endurance Championship presented by Mission Foods, the first major endurance race championship in the U.S. for vintage and historic sports cars. The Mission Foods series awards the top performers in the season’s four HSR Classic Endurance Championship races at Sebring, Watkins Glen International, Michelin Raceway Road Atlanta and Daytona International Speedway.
The HSR Sebring Classic 12 big winner was the 901 Shop – the Florida-based team that has raced and won in HSR for decades – that swept three of the race’s four competing Run Groups. Even better, 901’s drivers each secured their first overall HSR Classic Endurance Run Group victories, with all three runs to victory largely controlled and trouble free.
One of HSR’s top drivers, Todd Treffert has been victorious in just about every class and series he has contested in HSR’s season-long sprint and endurance championships. A victory in any HSR Classic race has eluded Treffert over the past decade, however, but that dry spell finally ended Sunday.
Treffert finished first or second overall in the combined Run Group A and B races for all four segments. Avoiding the attrition that sidelined several of his main competitors in Group B, Treffert carried a lead into Sunday’s fourth and final round. A late but non-contact spin barely cut into Treffert’s lead, and he finally secured an HSR Classic win in his 1975 No. 41 Porsche 911 Carrera Cup RSR “Baby” Turbo.
The Run Group A winner also never strayed from the top of the order and even ranked in the overall Group A and B top three at the race’s halfway point. David Agretelis won the second Group A race to take a lead he would hold to the finish in his 901 Shop 1972 No. 166 Porsche 911 S/T.
Like Treffert, it was a long time coming for Agretelis, who mentioned in his victory lane interview he had been trying to win an HSR Classic race for eight years.
The third 901 Shop winner was Tom McGlynn in his bright green Type 991.1 No. 8 Porsche 911 GT3 R in Run Group D. As usual, the division turned into a typical and hard-fought battle among a deep field of GT Modern (GTM) competitors, but McGlynn took early control and swept all four Group D segments. He joins his teammates Treffert and Agretelis as a first time overall HSR Classic Endurance series race winner.
Last weekend’s fourth winner was the 2017 No. 02 Matador Motorsports Cadillac DPi co-driven by Pierce Marshall and Eric Foss in Run Group C. The victory avenged a loss to Bob Neapole and Guy Cosmo in the RBN Motorsports with Cosmo-Sport 2020 No. 60 Acura ARX-05 prepared by Hudson Historics in last December’s HSR Classic Sebring 12.
Although the breakout victory by Neapole and Cosmo in December stopped Marshall and Foss from sweeping 2024’s trio of HSR Classic races, the No. 02 team now has a solid record of three wins in the last four HSR Classic events run dating back to Watkins Glen last year.
Several teams have doubled up on HSR Classic Endurance by Mission Foods Run Group victories in the past, but the 901 Shop is the first to win three different Groups in a single race. In the inaugural HSR Daytona Classic 24 Hour in 2014, Hudson Historics and team co-drivers Paul Reisman and his son John Reisman drove a Lola B2K/40 to the Run Group D win and backed it up with a Group F win – which is now Run Group G – in a quick Porsche Boxster. Most recently, Iconic Racing co-drivers Gérard Lopez and three-time Le Mans 24 Hour winner Marcel Fassler won Group A in a Lola T70 Mk III and Group F in an ex-JDC Motorsports Cadillac DPi in 2023.
Next up on the 2025 HSR schedule is the 47th HSR Mitty presented by Hagerty at Michelin Raceway Road Atlanta (MRRA), April 24 – 27. The next round of the inaugural HSR Classic Endurance Championship presented by Mission Foods will be the HSR Watkins Glen Classic 6 Hour presented by Mission Foods, June 12 – 14 at Watkins Glen International.
