Lamborghini’s Maiden IMSA GTD Championship: The Night It Became Real
Bryan Sellers, Madison Snow, and endurance specialist Corey Lewis brought the No. 48 Paul Miller Racing Lamborghini Huracán GT3 home in third place at the 2018 Motul Petit Le Mans, and that modest finishing position was enough to clinch something the brand had never achieved: a full-season IMSA WeatherTech SportsCar Championship in the GT Daytona class. Driver title. Team title. Manufacturer title. All three, in one evening, at Road Atlanta.
The final margin told the story of how close the whole thing came to slipping away. Sellers and Snow finished the season on 333 points, just four ahead of their closest rival. Lamborghini says it also claimed the manufacturer championship over Acura by 12 points, 345 to 333. For a brand that built its identity on road cars so extreme they bordered on conceptual art, earning a professional racing championship through sheer consistency over 11 rounds represented a different kind of validation entirely.
This was Paul Miller Racing’s inaugural championship as well. The team had finished on the GTD season podium three times in the preceding four years without ever converting that consistency into a title. The 2018 result broke through a ceiling that both the team and the manufacturer needed to shatter.
The Season-Long Battle with Acura: Four Points and Months of Pressure
The 2018 GTD championship fight pitted the No. 48 Lamborghini Huracán GT3 against the Acura NSX GT3 driven by Katherine Legge, and the rivalry defined the entire second half of the calendar. Lamborghini says the No. 48 car held the class points lead for the final nine races of the season, but that lead proved far more fragile than a nine-race streak might suggest.
Two races before the finale, the gap had stretched to 18 points. Acura’s charge whittled it down significantly. Entering the Petit Le Mans, the margin sat at seven points according to Lamborghini’s account (one independent report puts it at six). Either way, the math was simple: a bad race at Road Atlanta would erase everything.
The 10-hour race itself played out like a chess match with constant position swaps. Snow ran at the front early while the Acura fell back, then Acura co-driver Alvaro Parente closed to second and the two cars traded places through a series of pit cycles. Sellers climbed back in with roughly two hours remaining and guided the car to third, one spot behind the Acura on the road but comfortably ahead in the championship. That paradox captures endurance racing’s strategic depth: you can finish behind your rival in a single race and still beat them for the title.
Across 11 races in 2018, the team accumulated eight podium finishes, with one report indicating top-five results in 10 of those events. Their two outright victories came at the Mobil 1 Twelve Hours of Sebring and the Northeast Grand Prix at Lime Rock Park. A third-place finish at the Rolex 24 At Daytona set the tone early. That kind of relentless accumulation, rather than sporadic brilliance, defined the campaign and ultimately proved decisive.
Why This Championship Changed Lamborghini’s Racing Story
Before 2018, Lamborghini’s motorsport reputation rested on its one-make Super Trofeo series and the Huracán GT3‘s scattered victories in various global championships. The brand competed, sometimes won, but lacked the definitive season-long result that separates a serious racing manufacturer from one that merely participates. Ferrari and Porsche could point to decades of factory championship trophies. Lamborghini could not.
The IMSA GTD title changed the conversation. Winning a North American professional championship against established GT3 machinery from Acura, Mercedes-AMG, BMW, and others demonstrated that the Huracán GT3 could sustain competitive performance over a full season of sprint and endurance events, from the 24-hour grind at Daytona to short-format races at circuits like Lime Rock. That breadth of capability matters enormously to the customer teams who write the checks for GT3 programs. A car that wins one race but retires from three others is a liability. It podiums in 44% of its starts, the rate Snow and Sellers achieved together over their partnership, is a business proposition.
Paul Miller Racing’s trajectory illustrated how customer racing programs typically mature. The team had finished runner-up in the GTD championship standings in 2014 and third in both 2015 and 2016, followed by an uncharacteristic eighth-place result in 2017. Years of near-misses, a stumble, then a breakthrough. The team learned the Huracán GT3’s limits, Lamborghini’s Squadra Corse engineers refined the package, and eventually the combination clicked.
The Huracán GT3 as a Customer Racing Platform
Raw pace alone did not make the Huracán GT3 compelling in the GTD class. GT3 regulations use Balance of Performance adjustments to equalize cars from different manufacturers, so no single car enjoys a permanent power or weight advantage. The differentiator becomes reliability, driver confidence, and how well the car manages its tires over long stints.
The Huracán GT3 built its reputation on a naturally aspirated V10 architecture that delivered predictable power delivery, a quality endurance drivers consistently value. In a 10-hour race, the driver who can trust the throttle response lap after lap without managing turbo lag or hybrid system quirks carries a genuine advantage, even if the raw numbers on a dyno sheet look identical to the competition. Snow and Sellers recorded only two DNFs across their entire multi-year partnership, a reliability figure that speaks to both the car’s engineering and the team’s preparation.
The platform first appeared in the WeatherTech Championship’s GTD class in 2016, earning its debut victory at Virginia International Raceway that August. From that first win to the 2018 championship took just two full seasons, a rapid trajectory for a car competing against the Ferrari 488 GT3 and Porsche 911 GT3 R, both of which carried far longer GT3 development histories.
For prospective customer racing buyers, the 2018 result served as the strongest possible sales pitch. A championship-winning car with documented reliability, backed by a factory support structure through Squadra Corse, represented a competitive package that could justify the investment required to run a professional GT3 program.
Building on the Foundation: What Came After 2018
The 2018 title proved to be a beginning rather than a peak. Lamborghini repeated as GTD Manufacturers’ Champion in 2019, and Paul Miller Racing won the 2020 Rolex 24 at Daytona with the Huracán GT3, adding the 2020 Michelin Endurance Cup to their trophy case. Over their six-season partnership, the team accumulated six wins, 25 podiums, and 10 pole positions with Lamborghini machinery. Further manufacturer successes included the Michelin Endurance Cup in 2018 and 2020, and the Sprint Cup in 2021.
The partnership between Paul Miller Racing and Lamborghini concluded in November 2021. One report indicates the split stemmed from a disagreement over driver lineups: Lamborghini offered the team a move to the newly created GTD Pro class, which would have required an all-factory driver roster, but Paul Miller Racing chose to remain in GTD to continue racing with Sellers and Snow. The decision reflects a tension inherent in customer racing programs, where factory ambitions and team loyalties do not always align.
The broader significance, though, lies in what the 2018 championship enabled. Lamborghini’s GT3 customer racing program grew from a credible competitor into a proven championship winner, and that credibility carried forward into every subsequent season.
From Huracán GT3 to Temerario GT3: The Next Chapter
When Car and Driver reported on the Temerario GT3‘s reveal at Goodwood in 2025, the context was unmistakable: the new car replaces a platform that won championships, not one that merely showed up. According to Car and Driver, the Temerario GT3 represents Lamborghini’s first race car entirely designed and developed at the Sant’Agata Bolognese facility. It replaces the Huracán GT3 Evo 2 and carries a modified version of the road car’s twin-turbocharged V8, stripped of its hybrid system per GT3 regulations. The engineering philosophy shifts from naturally aspirated to forced induction, a change that will alter the driving character teams have spent nearly a decade learning.
For customer teams building their programs around the successor platform, the 2018 championship season provides the benchmark. The Huracán GT3 proved that Lamborghini could deliver a car capable of winning across formats, from 24-hour endurance races to short sprints, with the reliability to sustain a points chase over an entire calendar. The Temerario GT3 inherits that expectation.
Lamborghini’s LMDh prototype program with the SC63 followed a different trajectory. Jalopnik reported in 2025 that the company ended the program after two seasons without achieving the results it sought. That outcome makes the GT3 program even more central to Lamborghini’s racing identity going forward. The customer racing ladder, from Super Trofeo through GT3, remains the backbone of Squadra Corse’s competitive presence, and the credibility to sustain that ladder traces directly back to what Sellers, Snow, Lewis, and Paul Miller Racing accomplished at Road Atlanta in October 2018.
The four-point margin that decided the 2018 championship looks thin on paper. What it represented for Lamborghini’s motorsport program was anything but.
