Unveiling the 963 RSP: Explore Porsche’s Groundbreaking Street-Legal Le Mans Hypercar!

For a long time, road cars and race cars looked somewhat similar. But starting in the 1960s, they began to drift apart, especially in events like Le Mans. Today, cars at the top of the grid resemble Formula 1 machines more than everyday vehicles, like the 911.

This brings us to the Porsche 963 RSP, a unique blend of racing prowess and street legality. It’s a LMDh race car modified just for road use. We spoke with the people who made this fascinating project come to life.

Last year, when Porsche marked the 50th anniversary of the iconic roadgoing 917, a few key team members brainstormed innovative ways to reignite this legacy. Their inspiration came from a car made for Count Rossi, who famously used it on the streets of Alabama. Timo Resch, CEO of Porsche Cars North America, described their early meetings as a “submarine project”—something hidden from the public eye until it was fully formed.

Creating a fully street-legal 963 proved too complex; it would lose its identity. Instead, they focused on making a one-off version that could navigate the streets under special permissions.

Porsche partnered with Porsche Penske Motorsport for this endeavor, deciding that Roger Penske himself was the ideal owner. The 963 RSP is entirely new—no reused race car parts here. Instead, it was crafted from a fresh chassis at Porsche’s Atlanta headquarters. Behind the scenes, the technicians worked with care to ensure every detail honed in on the essence of the race car while also accommodating road use.

Jonathan Diuguid, managing director at Porsche Penske Motorsport, explained that while they softened certain systems, they kept the racing spirit intact. The finish quality is much higher than what’s seen on race cars, featuring a polished carbon fiber body and a carefully designed interior with luxurious Alcantara and leather accents. Unique touches, like a 3D-printed cup holder, highlight its road-friendly nature.

The design wasn’t merely about amenities; the team had to modify the bodywork to meet licensing requirements. The 963 retains its racing soul with a 4.6-liter twin-turbo V8 and a hybrid system powered in part by Bosch. The race version boasts around 700 horsepower, making it a true powerhouse whether on track or pavement.

Interestingly, the 963 shares about 80% of its components with the 918 Spyder’s V8, simplifying its road adaptation. The hybrid system was adjusted for smoother operation, which is crucial for everyday driving.

Despite its impressive specs, the 963 RSP rides on Michelin rain tires and features soft dampers for a more comfortable street experience. And yes, it has turn signals and a horn. However, starting the car is a bit more complex—requiring a laptop and the guidance of a specialized race team.

With special permission from French authorities, this remarkable car could drive around Le Mans, where longtime Porsche driver Timo Bernhard found the experience surreal. The car will soon be showcased at events like the Goodwood Festival of Speed before its final handover to Penske.

While Porsche has no immediate plans to produce more street-legal 963s, they’re open to possibilities in the future. As Urs Kuratle, head of Porsche’s LMDh project, suggested, “Never say never.”

This blend of engineering and nostalgia reflects a rich history while setting the stage for future endeavors, keeping both racing and road car spirit alive.
