When was the last time Porsche won manufacturer championships in the IMSA WeatherTech SportsCar Championship in the same year in different classes with a factory team and a customer team?

“It’s not often, that’s for sure,” joked Urs Kuratle, Porsche Motorsport’s director of Factory Racing LMDh.

The illustrious German automaker won the manufacturer championship last month in the Grand Touring Prototype (GTP) class at the season-ending Motul Petit Le Mans on the strength of its two Porsche Penske Motorsport factory entries. At the same time, Porsche won the manufacturer championship in the Grand Touring Daytona Pro (GTD PRO) class with the help of AO Racing, its top-performing customer team in GT classes.

The unusual accomplishment embodies Porsche’s wide-reaching influence and success in the history of endurance racing. The significance of the accomplishment didn’t hit Kuratle at the October finale until competitors began congratulating him.

“It took me a while to realize what we just achieved on the whole thing,” he said. “Sometimes you realize it only from the reaction of external people who congratulate you. … It takes everybody a while to realize something like this.”

The GTD PRO championship reflected Porsche’s rich history of customer racing and its other programs and ladder series, including Porsche Carrera Cup North America that competes under the IMSA umbrella.

“It’s becoming that big and that much a part of the history of Porsche that the marketing purpose still is clearly there,” said Volker Holzmeyer, president and CEO of Porsche Motorsport North America. “Porsche is a sports car manufacturer. The best way to prove that is to have success on the track. If your customers have success on the track, it’s an even better story.”

This unusual chapter in the company’s history began in 2022, when Porsche engineers began the task of sorting out the new LMDh car that would fill the GTP class in IMSA and the Hypercar class in the FIA World Endurance Championship (WEC) for the 2023 season.

“We had experienced people on board, but we had to bring them together as a group,” Kuratle said. “We were working quite intensively throughout last year. Toward the end of last year, we already could see in IMSA as well as in WEC, some success on track.”

Almost immediately, reliability became the primary issue. The hybrid-based car was unlike anything Porsche had produced. It was fast when it wanted to be, but a pain when it didn’t.

“We were not famous for being the most reliable team or the most reliable car for a number of reasons,” Kuratle said of the ’23 season. “That was something we worked really hard at during the offseason. Then we won Daytona this year. I’m not saying we overcame all of the problems yet but the reliability was a huge step.”

The footings for that step showed in late 2023, when Porsche Penske Motorsport’s No. 6 and No. 7 cars finished first and second at Indianapolis Motor Speedway. It was clear the new Porsche 963 had considerable speed, setting the path for this season.

“The biggest chunk of it was reliability and structural changes within the team,” Kuratle said. “The smallest part probably was performance, but it was there, as well.”

As Kuratle mentioned, Porsche came out of the gate strong in 2024, with the No. 7 entry winning the Rolex 24 At Daytona in January. It kick-started a season that saw the No. 7 accomplish the rare feat of leading the team and driver championships from start to finish, adding one more win (Watkins Glen) and five additional podium results along the way. The No. 6 Porsche, with two wins of its own (WeatherTech Raceway Laguna Seca and Road America), placed second to its sister car in the GTP championship.

On the GTD PRO side, the challenge for 2024 was finding a new partner to replace Pfaff Motorsports, which went with McLaren for the 2024 season. Porsche, which had won GT class championships three of the previous four years, found a solid match with AO Racing.

Trouble is, it was facing some stout factory teams.

“That’s what makes us really proud,” Holzmeyer said. “With a factory effort, you put a little money in it and you control everything. I wouldn’t say it’s easier, but for a customer team to accomplish that, it really comes from the heart.”

AO put together a remarkable season with its No. 77 Porsche 911 GT3 R – three wins in 10 races, a team championship and driver championship by Laurin Heinrich – to secure the manufacturer championship for Porsche, which embraced the team’s keen dinosaur-themed liveries.

“It was a genius idea,” Holzmeyer said. “They’re getting the new generation excited about racing. This will help us – maybe not next year, but in the future. Everybody needs to thank them for that, even the competitors. If you saw the lines at the autograph sessions, it was all young kids and families.”

So, while the past – including the most recent part of it – is on everyone’s minds, the future is in Porsche’s immediate plans.

“We will always have customers who want to race the IMSA program with our products and stay within the product family,” Holzmeyer said. “For next year, I don’t see any reasons why the success story shouldn’t continue.”
