      The return of GTP racing to IMSA gets a big thumbs-up from fans

    #59: Proton Competition, Porsche 963, GTP: Harry Tincknell, Gianmaria Bruni, Neel Jani races through Turn 12 during the 26th Annual Petit Le Mans race on October 14, 2023 at Michelin Raceway Road Atlanta in Braselton, Georgia.

    IMSA provided flights from Washington, DC, to Atlanta and four nights in a hotel so we could attend Petit Le Mans. Ars does not accept paid editorial content.

    The crowd streamed onto the track before the race, seizing their last chance to see the brightly liveried cars up close. Daytona had been busy in January, but the crowd at Road Atlanta seemed even larger. To be honest, though, the race the fans were here to see would not be one for the ages. A 52-car grid packed into just 2.8 miles of race track promised potential trouble, and the 10-hour race saw 14 interruptions by the safety car, never getting into a rhythm. But I’m not sure that mattered much; the main draw for many in attendance that Saturday was simply seeing this new era of hybrid prototypes in person, and on that score, everyone left with smiles.

    We’ve spilled plenty of pixels over the past 18 months or so delving into some of the minutiae of this new class of racing car, variously known as LMDh or GTP . Briefly, these are purpose-built racing cars, which start with a carbon-fiber spine from one of four racecar constructors and then add an engine, bodywork, and software from one of the four OEMs that participate, and then the same Xtrac gearbox, Williams Advanced Engineering lithium-ion battery, and Bosch electric motor as a way to keep development costs reasonable.

    The rules purposely limit the amount of aerodynamic downforce a car can generate relative to the amount of drag it creates, and they positively encourage each car maker to give these race cars styling that calls out to their road-going products.

      Aston Martin’s Valkyrie is going racing, but only after a power cut

    Aston Martin is set to return to the world's premier endurance race, the 24 Hours of Le Mans, with a prototype Valkyrie hypercar in 2025. The return to Le Mans also signals the marque joining the FIA World Endurance Championship (WEC) and the IMSA WeatherTech SportsCar Championship.

    Often talked about in hushed tones by people in the know, the idea of Aston Martin's halo hypercar entering the top flight of endurance motorsport has long been wished for, and the firm's announcement is sure to make race fans happy. The Gaydon, UK, company intends to enter at least one Valkyrie in both WEC and IMSA from 2025, giving itself a chance to take the top step at Le Mans, the Rolex 24 at Daytona, and the 12 Hours of Sebring.

    The basis for the competition car is set to be the Aston Martin Valkyrie AMR Pro , an even more hardcore version of the already rather raucous Valkyrie road car. The car with license plates boasts a Cosworth-developed 6.5-liter V12 packing 1,000 hp (745 kW), mated to a 160 hp (120 kW) electric motor, giving it an F1-style kinetic energy recovery system. Its hybrid setup makes it a ferocious thing.

      Here’s what it’s like to drive the new Porsche 963 prototype

    Last month, Porsche used the Goodwood Festival of Speed in the UK to formally debut its newest model. It's not another 911, nor a new SUV; it's a hybrid sports prototype designed to win on track here in the US and at Le Mans. You can tell the car has big shoes to fill just by looking at its name—Porsche is calling the new racing car the 963 because it's the spiritual successor to the legendary 962 that dominated sports car racing in the 1980s.

    Unfortunately, Goodwood took place at the same time as my vacation at Watkins Glen in New York for IMSA's six-hour race, so Ars wasn't able to see the 963 run in person. But I was able to sit down with a pair of Porsche's factory racing drivers to find out a bit more about the new car.

    Mathieu Jaminet and Matt Campbell are currently contesting the IMSA WeatherTech championship in a GT car—a Porsche 911 GT3R that started life on the same production line as the road-going 911s. But next year, the pair will be among the Porsche factory drivers who have been chosen to campaign the faster, more complex 963 here in the US or in the World Endurance Championship (WEC).

    On Monday, BMW became the first carmaker to reveal its new hybrid racing prototype built to the new LMDh rule set. It's called the BMW M Hybrid V8, and it will race for the first time at next January's Rolex 24 in Daytona.

    Sports car racing is in the midst of a transition period as race organizers in the US and Europe adopt new rules for prototype race cars. Because we're talking about sports car racing, and because there are two sets of organizers, it's all a bit complicated.

    The 24 Hours of Le Mans is organized by the French Automobile Club de l'Ouest, or ACO. Many of the cars that run in that race also compete in the World Endurance Championship, which is organized by the Federation Internationale de L'Automobile (or FIA). In the US, there's the International Motor Sports Association (IMSA), which runs the WeatherTech championship.
