After weeks of rumors, Pfaff Motorsports is set to pause its IMSA GTD PRO program after the 2026 season.
The news comes shortly after Pfaff gave the new Lamborghini Temerario GT3 its first IMSA win at Road America, with Andrea Caldarelli and Sandy Mitchell driving the No. 9 car.
Pfaff has been an important part of Lamborghini’s new GT3 program. The team gave the Temerario GT3 its global race debut at Sebring and is currently the only IMSA team running the car.
That leaves one big question: what happens next for Lamborghini in IMSA?
If Lamborghini wants to keep the Temerario GT3 in GTD PRO after Pfaff leaves, another team will need to take over the program. The car has already shown it can win, but now the focus turns to who will run it next.
Riley Motorsports
One possible candidate is Riley Motorsports, a team already familiar with Lamborghini.
Riley previously worked with the Italian manufacturer in 2025, helping run the Lamborghini SC63 LMDh in IMSA’s top GTP class before that program was paused at the end of the season.
Today, Riley Motorsports competes in the GTD class with Ford Racing, running the No. 16 Ford Mustang GT3 Evo. However, it has been a difficult campaign for the Mustang program. The entry currently sits 11th in the standings, with its best result being a seventh-place finish at the Grand Prix of Long Beach.
A return to Lamborghini could be the reset Riley needs. The team already has experience with the brand, and taking over the Temerario GT3 program could give the legendary sports car squad a fresh path back toward the front of the GTD PRO field.
Wayne Taylor Racing
Another strong option is Wayne Taylor Racing, which already has a current relationship with Lamborghini.
WTR is running the older Lamborghini Huracán GT3 Evo2 in the GTD class, where Trent Hindman and Danny Formal scored a class win this season at WeatherTech Raceway Laguna Seca in the No. 45 Lamborghini.
At the same time, Wayne Taylor Racing is also known for its GTP partnership with Cadillac, where it runs two of the American brand’s LMDh cars. That makes WTR one of the few IMSA teams currently working with two different manufacturers in the WeatherTech Championship.
Because of that existing Lamborghini connection, WTR would make a lot of sense as a possible successor to Pfaff. The team already understands IMSA, already understands Lamborghini GT machinery, and has the structure to compete at a high level.
Meyer Shank Racing
While Meyer Shank Racing has not been rumored as heavily as Riley or WTR, it could be one of the most interesting options for Lamborghini.
MSR is set to leave the GTP class at the end of the year due to Acura’s withdrawal from IMSA after 2026, which leaves the team searching for a new way to remain in the WeatherTech Championship. If MSR wants to stay in IMSA beyond 2026, taking over Lamborghini’s GTD PRO effort could be a strong fit.
The two-time Indianapolis 500-winning team is no stranger to IMSA GT competition. Before its successful run with Acura in prototypes, Meyer Shank Racing competed in GTD with the Acura NSX GT3 Evo from 2017 through 2020. That program produced major success, including back-to-back IMSA GTD championships in 2019 and 2020.
Of course, MSR’s long-term goal appears to be staying in GTP. A Lamborghini partnership could potentially open that door as well. If Lamborghini ever decides to revive the SC63 LMDh program, a GTD PRO partnership with MSR could be a natural first step toward rebuilding that relationship.
The SC63 did not produce many major results during its short IMSA run, but it did show progress late in its program. In its final start to date at the 2025 Motul Petit Le Mans, the No. 63 Lamborghini finished fourth overall with Romain Grosjean, Daniil Kvyat, and Edoardo Mortara, and it came close to an even stronger finish before a late stop with just minutes remaining.
For MSR, running the Temerario GT3 could be a way to stay in IMSA now while keeping a possible GTP future alive.
Grasser Racing Team
If there is one Lamborghini customer team that would feel like a natural fit for IMSA, it is Grasser Racing Team.
GRT would be an ideal candidate to replace Pfaff and take over Lamborghini’s GTD PRO program in 2027. The Austrian team already has experience with the new Temerario GT3, and it has already found success with the car. In DTM, Mirko Bortolotti gave the Temerario GT3 its first competition victory with a win in the Sunday race at Oschersleben.
Grasser also has a strong history in IMSA. The team first appeared in the WeatherTech Championship at the 2017 Rolex 24 at Daytona, entering the GTD class with a Lamborghini Huracán GT3. That debut started a successful IMSA endurance program for the Austrian squad.
GRT’s biggest IMSA achievements came in the major endurance races. The team won the GTD class at the 2018 Rolex 24 at Daytona, then returned in 2019 and won Daytona again, becoming back-to-back Rolex 24 GTD winners. Later that same year, Grasser added another major victory by winning the Mobil 1 Twelve Hours of Sebring.
The team continued to make IMSA appearances with Lamborghini through 2021, including with the No. 19 Lamborghini Huracán GT3. Its most recent IMSA start came at the 2021 Motul Petit Le Mans at Road Atlanta, where the car was driven by Misha Goikhberg, Franck Perera, and Michele Beretta.
Given GRT’s Lamborghini history, IMSA experience, and early success with the Temerario GT3, it could be one of the most logical choices to take over from Pfaff.
What Comes Next?
Lamborghini has a race-winning GT3 car in the Temerario, but Pfaff’s exit means the future of the program now depends on who steps in next.
Riley Motorsports has previous Lamborghini ties. Wayne Taylor Racing already runs Lamborghini GT machinery. Meyer Shank Racing could use the program as a way to stay in IMSA and potentially build toward a future GTP return. Grasser Racing Team has deep Lamborghini experience and a proven record in IMSA endurance racing.
The big question remains the same though : Who will carry the Temerario GT3 into IMSA’s next chapter?
