Countdown Winds Down to Start of New Sprint Challenge Season

The Porsche Sprint Challenge North America by Yokohama season will kick off at Sebring International Raceway this weekend, hosting the first of eight double-header weekends for PSCNA, with nearly 50 cars in attendance across five classes and two sets of races.

One set will feature Porsche 911 GT3 Cup car models – 19 entries with Type-992 GT3 Cups and 13 entries with 991 GT3 Cups – while the other will feature 16 Porsche Cayman GT4 Clubsport cars.

Coming off back-to-back events with the FIA World Endurance Championship 1000 Miles of Sebring and the IMSA-sanctioned Twelve Hours of Sebring just last week, the 3.7-mile racetrack has held a PSCNA event each year since the series’ inception in 2021.

The driver and eventual class champion who swept both Cayman GT4 Clubsport races at Sebring last season, Aiden Kenny, returns to defend his victories, albeit now in the top-tier 992 GT3 Cup Pro/Am class with ACI Motorsports.

One of the drivers joining Kenny in the Pro/Am field will be Madeline Stewart, who was newly named with Porsche Carrera Cup North America champion team JDX Racing. Stewart, who hails from Queensland, New Zealand, finished a two-year stint in the Porsche Michelin Sprint Challenge Australia series racing 991 GT3 Cup cars before making her switch to the U.S. and now the 992 GT3 Cup. Stewart had the opportunity to test with JDX at Barber Motorsport Park in Alabama before getting a glimpse of the Sebring bumps earlier this month.

Scott Zdanis is another returning driver with prior winning experience in the North American championship at Sebring. Zdanis took the first checkered flag of the 991 GT3 Cup season in 2022 en route to finishing third overall in the championship standings and will be back on the grid with his team, MGM.

Many of the nearly 20 teams this weekend at Sebring plan to field multiple entries, as Fall-Line Motorsports tops the list with nine; MDK Motorsports with five; the trio of JDX, Kelly Moss Road and Race, and RS1 with four; and others rounding out with two to three cars.

One such team is Tatum Racing with three cars and its stable of drivers bringing a range of experience. John McInnes – with assistance from his driver development coach Parker Thompson – will pull double duty this season between the Porsche Sprint Challenge North America and USA West series in the 991 GT3 Cup class.

Meanwhile, McInnes’ teammate, Nickolas Maloy, makes his series debut this weekend driving in the Cayman GT4 Clubsport Pro/Am category. Maloy, just 17 years old, seeks a coveted spot with the Porsche Motorsport Junior Driver Program based on his performance throughout the season.

In total, six drivers will compete for the 992 GT3 Cup Pro/Am wins this weekend, and 13 drivers each for the 992 GT3 Cup Am and 991 GT3 Cup wins. Nine drivers will run for the first pair of Cayman GT4 Clubsport Pro/Am wins and seven entries are set for the Am class.

All four 40-minute races this weekend listed below will stream live on FloSports, in addition to the Porsche Sprint Challenge North America by Yokohama YouTube channel.
