Porsche wraps up IMSA season second in manufacturers’ championship

The two Porsche 963 fielded by the Porsche Penske Motorsport factory squad went unrewarded for their tireless fight for the championship. In the last race of this year’s IMSA WeatherTech SportsCar Championship at Road Atlanta, the two hybrid prototypes from Weissach crossed the finish line in fourth and tenth in the top GTP class. The identical LMDh racing car from the Proton Competition customer team concluded the so-called 10-hour “Petit Le Mans” event on the winner’s podium in third place. In both GT classes, Porsche customer teams achieved podium results with the 911 GT3 R. 















The race

In sunny conditions and witnessed by large crowds in the US state of Georgia, almost everyone experienced a rollercoaster of emotions. The Porsche Penske Motorsport works team tackled the race with high hopes of winning the manufacturers’ title. The regular driver pairings Nick Tandy and Mathieu Jaminet (#6) as well as Matt Campbell and Felipe Nasr (#7) were also in the running for the drivers’ championship crown. However, the dream of winning the title in the first year of the new top GTP class was quickly shattered for the British-French duo. After just 75 minutes of racing, Tandy became the innocent victim of a shunt by two competitors. Although the No. 6 car was sent back out on the track after extensive repair work, it ended up in the barriers after being hit again – and was forced into retirement. At this point, works driver Laurens Vanthoor was behind the wheel of the Porsche 963. 


From then on, all hopes were pinned on the No. 7 sister car. After around two and a half hours of racing, Campbell catapulted the 963 into the lead for the first time thanks to some inspired overtaking manoeuvres. At that stage, Porsche, the Porsche Penske Motorsport team and the drivers Campbell/Nasr were at the top of the overall standings. Indycar star Josef Newgarden, who joined the regular crew as support, kept contact with the leaders during his stints and handed the No. 7 cockpit over to the Felipe Nasr. With three hours left on the clock, the Brazilian then swapped with the Australian again while running in fifth place. Setting impressive lap times and with steely determination, Campbell ploughed through the field – only for his charge to be thwarted by five safety car phases. The race finally ended under yellow, where the chance to overtake was no longer possible. Campbell/Nasr/Newgarden finished the “Petit Le Mans” in fourth place.















“We fought until the very last lap, but lady luck just wasn’t on our side today,” summed up Thomas Laudenbach, Vice President of Porsche Motorsport. “Our number 6 was out of the title race very early through no fault of its own. The crew in the sister car also lacked the necessary stroke of luck in the final phase, especially at the last refuelling stop. With three wins and two poles in the first year of competition with the Porsche 963, we can stand proud. The results in the second half of the season were clear evidence of a huge improvement throughout the year. Congratulations to the champions of the 2023 IMSA season and also to our customer team Proton Competition, who clinched their first podium at Road Atlanta.” 

“Cadillac took the title in a thrilling finale. Congratulations to them,” said Urs Kuratle, Director Factory Motorsport LMDh. “Congratulations as well to Proton Competition. Our customer squad fought hard for today’s podium finish with the Porsche 963. After the accident involving the number 6 car, we tried everything today to get the sister car in front. Unfortunately, that didn’t work out. We were fast, it was close, but we just didn’t quite pull it together. The others were simply a bit better today.”
















“In the last race of the first year with the Porsche 963 and our new team, we didn’t get the result we had hoped for,” summarises Jonathan Diuguid. The Managing Director of Porsche Penske Motorsport adds: “We all gave everything we had. Our number 6 car dropped out of the race due to accidents, then we put all our eggs in one basket with number 7. Unfortunately, some yellow flags came out at inopportune times for us. Other cars, which were hardly at the top during the race, suddenly appeared at the front. We would’ve loved to win a title, but unfortunately that didn’t happen. We’re looking to change that in 2024!”

One team to profit under the penultimate yellow phase was the Porsche customer squad Proton Competition. The No. 59 Porsche 963 helmed by works driver Gianmaria Bruni from Italy, Neel Jani from Switzerland and Englishman Harry Tincknell took the flag in third place. The identical prototype fielded by JDC-Miller MotorSports, which the regular drivers Mike Rockenfeller (Germany) and Tijmen van der Helm (Netherlands) shared with the British ex-Formula 1 world champion Jenson Button, finished in fifth place. 

Porsche wrapped up the 2023 IMSA season as runner-up in the manufacturers’ standings. In the drivers’ championship, the regular drivers Jaminet/Tandy and Campbell/Nasr are tied in fourth and fifth positions. 















GTD classes: Porsche 911 GT3 R finishes 10-hour race on the podium

In the two GT categories, as well, the final round of the season was packed with suspense from start to finish. In the GTD-Pro class, works driver Kévin Estre fought for victory at the wheel of Pfaff Motorsports’ Porsche 911 GT3 R in the last two hours. In the No. 9 car shared with regular drivers Klaus Bachler (Austria) and Patrick Pilet (France), the Frenchman was only 0.980 seconds shy of victory in second place.

In the GTD class, Wright Motorsports’ No. 16 entry seemed to be on track to score second place until the third-to-last lap, only to have an accident followed by a fire throw it out of contention shortly before the finish. Prior to this, the Porsche had already been shunted off the track by another competitor. Also during this phase, the nine-eleven campaigned by the customer team AO Racing dropped out of the top 3. Wright Motorsports’ No. 77 vehicle thus inherited third place just ahead of the customer Porsche of Kellymoss with Riley. At the end of the season, the sports car manufacturer from Stuttgart took third place in the manufacturers’ ranking of the GTD class. 

Nasr and Tandy briefly topped the timesheets

The rain eased for a short time halfway through qualifying, which allowed the racing line to dry out. At this time, Nasr and Tandy briefly topped the timesheets however, under these conditions the soft compound tyres quickly deteriorated. With around five minutes left on the clock, both of the factory-run Porsche 963 came into the pits again for fresh rain tyres. However, in the final bid to set a top time, any decisive improvements proved impossible.

“At first it was dry, then wet, later the track dried again. These were difficult conditions,” concludes Urs Kuratle. The Director Factory Racing LMDh adds: “I’m relaxed about the situation. Our drivers did a good job and we’re starting from the midfield. The race on Saturday runs over ten hours. It’s all about getting the car through the heavy slower traffic and over the whole race distance unscathed. The conditions are unlikely to improve on race day. We have to be in the front pack for the first eight hours. Then we’ll attack at the end.”















The customer teams

In the top GTP class, the customer teams JDC-Miller MotorSports and Proton Competition tackle the race with one Porsche 963 each. Germany’s Mike Rockenfeller and Tijmen van der Helm from the Netherlands are joined in the cockpit of the US team’s No. 5 car by the British Formula 1 world champion Jenson Button. Proton Competition’s No. 59 vehicle will be driven by Porsche works driver Gianmaria Bruni from Italy, Englishman Harry Tincknell and Neel Jani from Switzerland
