Vettel for Porsche in Le Mans 2024?

photo source: newsroom.porsche.com

Sebastian Vettel was testing the Penske Porsche 963 on the Porsche test track in Weissach on thursday. And without much preparation, he instantly was only a bit slower than Porsche WEC main driver Laurens Vanthoor. Porsche seems to be extremely astonished by Vettels speed and professionalism. He will also drive a 36 hour endurance test in Aragon next week. And Vettel said "we will see hot it continues afterwards."

A research of the trusted german motorsport website motorsport-total.com has found out that Vettel seems to be very interested, exactly as Porsche, to bring Vettel to Le Mans this year. If they decide for it, it's very likely that he will also race in the WEC race in Spa, because in Spa and Le Mans there will be a third Penske Porsche on the track, and right now only one driver (Mathieu Jaminet) is confirmed for the third car.

The 24 Hours of Le Mans is by far the most prestigious event in endurance racing. For 2025, the Hypercar category brings together the most advanced hybrid prototypes ever developed, with entries from global manufacturers under two distinct rule sets: Le Mans Hypercar (LMH) and Le Mans Daytona h (LMDh).

These are the top contenders for the 2025 24 Hours of Le Mans, machines that represent the forefront of hybrid endurance racing technology.

The BMW M Hybrid V8. Built under LMDh rules, it features a 4.0-liter twin-turbo V8 paired with a standardized hybrid system. Power is electronically capped at 680 horsepower, as per class regulations. Built on a Dallara chassis, BMW joined the WEC in 2024, aiming for overall victory in 2025.

The Ferrari 499P, a factory-built LMH car. It uses a 3.0-liter twin-turbo V6 mid-mounted, coupled with a front-axle hybrid motor for all-wheel drive. Like all entries in this category, it produces a combined 680 horsepower. After winning Le Mans in 2023, Ferrari remains a key contender.

The Aston Martin Valkyrie AMR-LMH enters in 2025. Based on the road-going Valkyrie, it features a high-revving 6.5-liter naturally aspirated V12 developed by Cosworth and a hybrid system. Despite the unique powertrain, total output stays within the regulated 680 horsepower limit.

Porsche’s 963 runs under LMDh regulations. It uses a 4.6-liter twin-turbo V8 derived from the RS Spyder, paired with a spec hybrid system, delivering a combined 680 horsepower. The chassis is supplied by Multimatic, and the car continues Porsche’s legacy in endurance racing.

Peugeot’s 9X8 brings bold design choices, most notably a no-rear-wing aerodynamic concept. It’s powered by a 2.6-liter twin-turbo V6 and a front-mounted electric motor. Like its LMH rivals, it runs with 680 horsepower and all-wheel drive above 150 kilometers per hour.

Toyota’s GR010 Hybrid has been the benchmark since 2021. It features a 3.5-liter twin-turbo V6 and a front-mounted electric motor, activated above certain speeds. The hybrid system helps deliver exactly 680 horsepower, balancing reliability and performance.

The Cadillac V-Series.R, competing under LMDh rules, uses a 5.5-liter naturally aspirated V8. It’s paired with the standardized hybrid system and mounted on a Dallara chassis. Known for its durability and aggressive sound, power is limited to 680 horsepower.

The new Alpine A424 is Alpine’s first LMDh entry. It’s powered by a 3.4-liter turbocharged V6 and a spec hybrid unit, built on an Oreca chassis. Like its competitors, the A424 is tuned to the FIA-mandated 680 horsepower limit. Designed in collaboration with Signatech, it marks Alpine’s serious push for overall victory.

All nine of these prototypes are engineered to deliver maximum performance within tightly controlled regulations. With equalized power outputs and diverse philosophies in aerodynamics and hybrid integration, the battle for Le Mans 2025 is all to execution, efficiency and endurance.

Vettels Porsche test in Aragon

On Tuesday, Sebastian Vettel completed his first real test in the Porsche 963 LMDh car of the WEC in Aragon, completing 118 laps and seemed to make a good impression. Vettel, in any case, was in good spirits and said, "Driving the Porsche 963 here in Aragon on the track was definitely fun." He further explained, "I had to get used to everything and find my rhythm. The feeling of driving is different just because of the roof over my head, as well as dealing with the higher weight and the tires. The Porsche factory drivers were very helpful and explained to me what is special and what I need to get used to."

Jonathan Diuguid, the head of the Penske-Porsche racing program, also seemed very impressed with Vettel's test, but left open whether Vettel will be at the start in Le Mans. "Sebastian Vettel testing for us here is a unique opportunity for the team. As a four-time Formula 1 world champion, he has immense experience with hybrid systems and high-performance racing cars. His fresh and unique perspective on where we stand with our Porsche 963, and his feedback on our systems, are extremely valuable," said Diuguid. Regarding Vettel in Le Mans, he said, "He got out of the car with a smile on his face, which is a good sign."

I will definitely keep you updated on the topic of Vettel and Le Mans.

What speaks for a Le Mans start?

Sebastian Vettel could compete in Le Mans with Porsche as early as 2024. The former Formula 1 world champion impressed in the first test. There are increasing signs of a racing comeback for the German. Porsche has postponed the planned announcement of the driver pairing of the third car for Le Mans.

Sebastian Vettel was abstinent for fifteen months. Apart from a few demonstration laps in a Williams FW14B at Silverstone and a Red Bull RB7 at the Nürburgring, the four-time world champion stayed away from the race track, but the thoroughbred racing driver regularly admitted that he misses racing. That's why his name was mentioned again and again when an attractive door opened-or seemed to open-in Formula 1, just like at Mercedes next year. The transfer of Lewis Hamilton to Ferrari frees up a cockpit at Mercedes, and of course Mercedes team boss Toto Wolff and Vettel were already in contact. The Heppenheimer also has his eye on the World Endurance Championship (WEC) with Porsche. On March 21st, Vettel took part in the roll-out test of the third Le Mans car in Weissach. The 36-year-old shared the cockpit with Porsche works driver Laurens Vanthoor. The Belgian drove two stints of twenty laps each, after which Vettel took over the Porsche hypercar for several runs between ten and fifteen laps.

Vettel fast straight away

According to information from our sister magazine, Motorsport aktuell, Vettel was on the same lap time level as Vanthoor after just fifteen laps. First conclusion: Vettel was immediately competitive at raw speed, and he also impressed with good feedback. The second stage of the test plan was then initiated: Vettel and five other works drivers will take part in a 36-hour test at the Spanish Motorland Aragón racetrack from March 25th to 27th, which was planned as preparation for Le Mans. The test is intended to evaluate how the 53-time GP winner copes with the 700 hp LMDh car in the dark. Vettel wants to use the test to find out whether the LMDh class cars will rekindle the fire in him. With a curb weight of 1,030 kilograms, the hybrid racers are significantly heavier than a Formula 1 car and have less power, but with hybrid technology and biofuel, they fit into the green world view of the man in the cockpit. The first impression behind the wheel of the Porsche 963 already left a clear mark on the thoroughbred racing driver from Heppenheim: "I'm looking forward to testing the Porsche and have already had the opportunity to get to know the car a little in Weissach. I've always had other racing series, and my curiosity for long distances encouraged me to just give it a try. Now I'm excited about the endurance run in Aragón and am looking forward to my time behind the wheel. It will definitely take some adjustment and some getting used to, but the whole team is very open and helps me with that. We'll see what happens next. At the moment there are no further plans for the future."

Porsche postpones driver announcement

After that, at the latest, a decision must be made as to whether Vettel will be included in Porsche's Le Mans squad. The Penske team will compete at Le Mans in 2024 with three cars: the two WEC cars plus an additional 963, which so far only has Mathieu Jaminet named. The original plan was for Jaminet to share the Porsche with Felipe Nasr and Nick Tandy. The trio should have been confirmed this week on Thursday, March 28, but that announcement was postponed. This suggests that there is a real chance that Vettel could still jump on the Le Mans bandwagon. The Heppenheimer is still keeping the ball low: "We'll see how things continue. At the moment there are no further plans for the future." Theoretically, it would be possible for Vettel to contest one of the two World Championship races in Imola or Spa, although not with the works cars, but with the two customer teams, Proton Competition or Jota Hertz Racing. Vettel would obviously like to drive a test race because this is the only way to optimally prepare for a race at Le Mans. As expected, there is no doubt about Vettel in terms of driving, but a test race would allow him to get a feel for the demanding traffic situation in endurance racing, where the fast hypercar top cars share the track with the much slower GT3 cars.

Further Porsche tests possible

Because of the great competition in the field, the sports prototypes are now the second most attractive racing series in the world. In Aragon, Vettel also gets to know the competition straight away. It's not just Porsche that is preparing for Le Mans. Alpine with Mick Schumacher has also registered on the Spanish route. If everything goes well, Vettel could complete a third test soon: Porsche will drive in Spa on April 5th and 6th, and there is also the possibility of another 36-hour test on April 10th and 11th at the French track Le Castellet, even if Porsche has not yet officially registered for the test. The decision on a Le Mans start must be made by mid-April at the latest. The Porsche board is said to be enthusiastic about the idea of ​​Vettel driving with Porsche at Le Mans as early as 2024.

Porsche against seven manufacturers

The Stuttgart team won the first race of the season in Qatar with the 963. The WEC is enjoying particular attention this year because eight manufacturers are represented: Porsche, Ferrari, Toyota, Peugeot, BMW, Cadillac, Alpine and Lamborghini. The 24 Hours of Le Mans is even more than usual one of the big motorsport highlights of the year. Another large car company, Aston Martin, is expected to join in 2025. There are persistent rumors about a McLaren entry. For Porsche, Vettel's testing is a prestigious experience. The example of Alonso at Toyota and Hülkenberg at Porsche shows what advertising value the deployment of a Formula 1 driver on foreign terrain can have. Thomas Laudenbach, Head of Porsche Motorsport, is pleased that the former champion is showing interest in Porsche's long-distance activities: "There was no question for us that we would be happy to support his request for a test opportunity and provide him with extensive preparation and sufficient time. We can certainly learn a lot from his valuable feedback. Our 36-hour endurance run with our factory drivers in Motorland Aragón offers a perfect environment for this."

At the 2025 24 Hours of Le Mans, Porsche unveiled a unique one-off vehicle: the Porsche 963 RSP. Developed as a tribute to the legendary 917 and inspired by Count Rossi’s 1975 street-driven prototype, the 963 RSP is based on Porsche’s LMDh competition car but reimagined for public roads under special conditions.

The project was a collaboration between Porsche AG, Porsche Penske Motorsport, and Porsche Cars North America, with direct involvement from Roger Penske—whose initials form the RSP name. The concept was initiated as a design study and passion project, eventually culminating in a street-legal prototype unveiled near Circuit de la Sarthe.

The 963 RSP retains the race-spec 4.6-liter twin-turbocharged V8 hybrid powertrain, delivering up to 680 horsepower. Originally developed for the RS Spyder and later refined in the 918 Spyder, the engine architecture includes a flat crankshaft, short stroke, and Van der Lee turbochargers for optimized throttle response. The hybrid system uses a Bosch motor generator unit and a Williams Advanced Engineering battery, working with a 7-speed Xtrac sequential gearbox. For road use, the power delivery was remapped to be smoother, and the system was configured to run on pump fuel.

To comply with road operation under French regulation, the chassis was adjusted with raised ride height, softened Multimatic dampers, and revised software to enable functioning headlights, taillights, and turn signals. Michelin rain-spec tires were mounted on 18-inch forged OZ wheels. Unique modifications such as covered wheel arches, a working horn, and license plate mounts were added.

Visually, the 963 RSP is finished in Martini Silver paint—not a wrap—requiring a triple-layer lacquer on ultra-thin Kevlar® and carbon fiber surfaces. An enamel Porsche crest replaces the standard nose graphic, and 1970s Michelin branding adds a period-correct touch. The rear features a 3D-printed “963 RSP” badge.

The interior departs sharply from the competition car. Trimmed in tan leather and Alcantara, it includes a cushioned, leather-wrapped carbon seat, air conditioning, a leather-finished steering wheel, and even a detachable 3D-printed cup holder. Storage space is provided for a laptop, headset, and Roger Penske’s custom carbon helmet. Ventilation outlets mimic the 917’s engine fan design, reinforcing historical continuity.

While the 963 RSP is not homologated for mass production, it is fully operational and authorized for limited road use under manufacturer permissions. Following its debut, the vehicle will appear at the Porsche Museum in Stuttgart and the Goodwood Festival of Speed.

This project showcases Porsche’s ability to blend heritage, engineering, and bespoke craftsmanship—all within the limits of a modern endurance prototype.
