The SC63’s Strategic Pause: A Recalibration, Not a Retreat
Lamborghini’s SC63 chose the worst possible time to look its most competitive. In the season-ending 10-hour Petit Le Mans at Road Atlanta, the #63 prototype ran at the sharp end of the GTP field for extended stretches, led the race outright on multiple occasions before scheduled pit stops, and emerged as the nearest challenger to the race-winning Cadillac in the closing stages. Then, with just over five minutes left on the clock and a stunning second-place finish within reach, the team pitted for a final energy stop. The car crossed the line fourth.
That fourth place stands as the SC63’s best-ever IMSA GTP result, and it arrived in the car’s final race before the LMDh program goes on pause for 2026. The timing is both encouraging and deeply frustrating, because it confirms the car was still on an upward development curve when the program stopped. Romain Grosjean, Edoardo Mortara, and Daniil Kvyat shared driving duties in the #63, and all three acknowledged the result as the car’s high-water mark. Mortara captured the mood precisely, calling it a “bittersweet end to the season” while pointing to the potential the car showed at both Indianapolis and Road Atlanta.
Lamborghini officials have been deliberate in calling this a pause, not a cancellation. Leadership, including Stephan Winkelmann and Maurizio Leschuitta, described a future return for the SC63 as “hypothetical,” and no WEC return has been announced. Pausing a program that was visibly improving is the kind of decision that only makes sense if the resources are genuinely needed elsewhere, and Lamborghini’s near-term motorsport calendar points toward the Temerario GT3 as the priority. Understanding what the SC63 achieved at Road Atlanta, and how it got there, reveals why this pause stings more than a simple withdrawal.
Petit Le Mans: A Bittersweet Best Result for the SC63
Grosjean started seventh after qualifying with a 1m10.309 lap, just hundredths off the second row. The opening stages were messy: two early full-course yellows disrupted the rhythm, and the SC63 initially fell to the back of the GTP pack after its first energy-only pit stop. Grosjean clawed back to 10th by the second restart, and from there the car’s race pace told a different story than its grid position suggested.
Mortara and Kvyat cycled through solid stints, keeping the car inside the top 10 through the middle hours. As fuel and energy strategy became the dominant factor in the second half of the marathon, the #63 led the race overall at multiple points before its scheduled stops. Contact with an LMP2 car damaged the front-left headlight, forcing the team to swap the entire front nose while Grosjean got back in for the final two-hour stint. Despite that unplanned stop, the car recovered its position.
Mortara and Grosjean alternated in the closing hours, and the SC63 remained firmly in the fight for a podium as the race entered its final minutes. With several GTP runners also needing late energy stops, the SC63 briefly sat second overall before the team’s own energy calculations forced one final pit visit. Five minutes proved too few to recover, and fourth was the result. The gap between what the car deserved and what the energy regulations allowed crystallized the central frustration of the SC63’s entire season: raw pace was no longer the problem.
Engineering Insights: The Upgraded Suspension and Future Development
The late-season surge did not happen by accident. Lamborghini brought an upgraded rear suspension to Road Atlanta, specifically designed to cope with the circuit’s notorious bumps. The team had already deployed a revised suspension via an “evo joker” (the LMDh regulations’ allowance for a targeted homologation update) ahead of the Indianapolis round, and the improvement was visible immediately. At Indy, the SC63 ran in podium contention before a late energy stop dropped it to 10th.
Lamborghini Chief Technical Officer Rouven Mohr acknowledged that the original rear suspension carried “weaknesses from the kinematical point of view” that needed correction. According to Mohr, both Grosjean and Mortara were satisfied with the updated package. The progression from Indianapolis to Road Atlanta confirms the kinematic fix addressed a real limitation: the car went from a promising but incomplete Indy run to its strongest race of the season at Petit Le Mans.
Mohr also indicated that with the suspension sorted, the next areas of development would target aerodynamics and weight saving. Whether those improvements ever reach the track depends entirely on what comes after the pause. Earlier in the season, the car matched its previous best of seventh at the Sahlen’s 6 Hours of the Glen, where Grosjean led for significant portions of the race. By Road Atlanta, the car was fighting for second overall against the full GTP field. That upward arc matters, because it means the engineering work Squadra Corse invested was producing measurable returns on track, returns that now sit in a holding pattern rather than feeding the next round of development.
The Full Picture: Huracán GT3 EVO2’s Challenging Weekend
While the SC63 delivered its best day, Lamborghini’s GT3 contingent endured one of its worst. The #9 Pfaff Motorsports Huracán GT3 EVO2, driven by Andrea Caldarelli, Marco Mapelli, and James Hinchcliffe, struggled all weekend with a mandated torque sensor issue that limited qualifying to a single timed lap and left the car 10th in class. Race day brought two drivethrough penalties for pit-lane infringements before an electrical failure forced retirement before the final hour.
The GTD entries fared no better. A multi-car incident on the opening lap at the Esses effectively ended the race for the #45 WTR entry of Graham Doyle, Trent Hindman, and Danny Formal. Contact from a Lexus broke the driveshaft, and while the team repaired the car behind the wall, it lost multiple laps and any hope of a competitive result. The #78 Forte Racing Huracán was also caught in the same opening-lap chaos, sustaining front-end damage. Both cars limped to the finish: the #45 in 12th, the #78 in 13th.
The GT3 struggles at Petit Le Mans underscore why the Temerario GT3 program looms so large in Lamborghini’s planning. The Huracán platform has served Squadra Corse well, but its successor needs to arrive with the kind of development momentum the SC63 was just beginning to build.
What’s Next for Lamborghini in Endurance Racing?
Petit Le Mans closed a compressed, challenging chapter. The SC63 made its competitive debut in March 2024 and ran a combined WEC and IMSA schedule in its first year before Lamborghini pulled back from WEC entirely for 2025. The 2025 IMSA effort, limited to five endurance races with a single Ligier-built car, was always going to be a development exercise as much as a competitive campaign. Judged on that basis, the late-season progression from seventh-place finishes to a fourth that could easily have been second represents meaningful growth.
The contrast with the broader LMDh landscape sharpens the point. Manufacturers like Porsche and Cadillac run multi-car, full-season programs with years of accumulated data. Lamborghini entered the top tier of endurance racing with a single prototype and staffed a development effort that was always operating at a smaller scale. The fact that the SC63 was running at the front of a 10-hour race in its final outing says something about the underlying engineering, even if the results sheet reads “P4.”
Lamborghini confirmed the 2025 driver roster of Mirko Bortolotti, Grosjean, Kvyat, and Mortara, but what happens to that lineup going forward is an open question. The SC63 will not compete in IMSA GTP in 2026, and the conditions for a restart remain undefined. The Temerario GT3 program is the confirmed next step. For now, the SC63’s fourth at Road Atlanta stands as the strongest evidence yet that the car deserved more time on track, and that the learnings Squadra Corse accumulated will matter whenever Lamborghini decides the pause is over.
