Prior to this weekend’s Lone Star Le Mans (5-7 September) – round six of the 2025 FIA World Endurance Championship campaign – Keely Bosn sheds light on her first season as Cadillac Racing Programme Manager.
The FIA World Endurance Championship is headed stateside this week, as Lone Star Le Mans kicks the action back into gear at Austin’s Circuit of The Americas (COTA) – an event that couldn’t have come at a better time for the series’ American Hypercar challenger, as Cadillac Hertz Team JOTA looks to build upon its memorable milestone win in the Rolex 6 Hours of São Paulo last time out.
“Racing on home soil is always special,” says Cadillac Racing Programme Manager Keely Bosn to fiawec.com. “Lone Star Le Mans is a chance for us to showcase Cadillac, not only to our US fans and employees, but also to FIA WEC fans around the world.”
Those fans were already treated to a Cadillac Hertz Team JOTA masterclass in Brazil, as the #12 Hypercar piloted by Alex Lynn, Will Stevens and Norman Nato led home the sister #38 V-Series.R crewed by Earl Bamber, Sébastien Bourdais and Jenson Button.
The result represented Cadillac’s maiden FIA WEC victory, and factory outfit JOTA’s second outright Hypercar success. “The team on the ground did an amazing job,” lauded JOTA’s co-founder, Sam Hignett, “but there are hundreds of people behind-the-scenes at JOTA, at GM, at Cadillac and Dallara. All this credit needs to go to them as well, because without them, we wouldn’t be where we are today.”
“That one-two finish was quite the breakthrough for us – really a defining moment for Cadillac Racing in FIA WEC. It proved that Cadillac can win against the best, which gives us huge confidence heading into Austin as well,” adds Bosn.
As the team that finally put an end to Ferrari’s unbeaten start to the season, Anglo-American alliance Cadillac Hertz Team JOTA will tackle the final three races of 2025 with renewed determination and hunger to succeed. “Once you taste victory, it’s not enough,” asserts Bosn. “We’re here to contend every single weekend. We’re going to be chasing trophies for the remainder of the season.”
Thanks to its 44-point haul in Brazil, Cadillac has breathed fresh life into the Manufacturers’ battle, with the Prancing Horse’s margin at the top of the table now reduced to 55 points. “I’d say we’re right where we want to be,” sums up Bosn. “We’re in a good position to fight for the Manufacturers’ Championship this year.”
It has not always been the case. Rewind to the curtain-raising Qatar 1812km, and the mood within the camp was decidedly less buoyant, after Button and Lynn got caught up in an intra-team collision while leading the Hypercar pack. The only way forward was up, and Cadillac duly delivered, clawing its way back with a streak of consistent performances at Spa-Francorchamps and Le Mans before the Interlagos one-two.
“Week-by-week, JOTA has continued to improve,” acknowledges Bosn. “That growth has made us, at Cadillac and General Motors, very proud. We have gone from a bit of a rocky start to a serious threat on the track. That shows the resilience of this team. They have the Cadillac spirit.”
Team spirit has been more needed than ever as Bosn has navigated a handful of challenges during her first FIA WEC campaign as Cadillac Racing Programme Manager, most notably the factory team change from Chip Ganassi to Hertz Team JOTA and the switch to a two-car entry to comply with the mandatory regulations to score points in the FIA Hypercar World Endurance Manufacturers’ Championship.
“We started off building one Cadillac team across both IMSA and FIA WEC, no matter what the badge is on the garage door,” she explains. “The unity of our teams is really starting to pay off. Juggling a global programme is no easy task, but seeing it come together as one team has made all the hard work worth it.”
Fortunately, the American is familiar with hard work and team-building in a performance-centric environment, having previously served as a logistics officer in the US Navy. Her time in the Armed Forces involved several deployments in the Middle East in support of Special Forces personnel. “The US military really helps in teaching you how to work under high pressure,” she says. “It also teaches you the value of trusting your team. In racing, those lessons aren’t just useful – they’re everything. The foundation of how you win races is to know your team, to trust them. For me, that is not something new.”
Bosn, whose love for motorsport stems from her father, a former drag racer, has worked her way through the Corvette Racing programme in IMSA to General Motors’ flagship effort in endurance racing. “To lead Cadillac against Ferrari, Toyota, Porsche and so on, is the challenge that people live for. It’s an absolute dream job.”
