Here’s a stoplight drag race we’d like to see at a future Woodward Dream Cruise: the Porsche 963 RSP vs. the Cadillac V-One.
At Carmel, California’s summer autopalooza last week, The Quail, General Motor’s luxury brand unveiled the wicked-looking V-One Concept based on the Cadillac V-Series.R Hypercar that endurance races across the globe from Daytona to Le Mans.
The V-One comes a little over a year after Porsche’s street-legal hypercar — also based on their Le Mans endurance racer — debuted at the 2025 24 Hours of Le Mans in France. The car was gifted by Porsche to Roger Penske, Porsche’s partner in international sports car racing.
Like the 963 RSP (short for Roger Searle Penske), the V-One is a street-focused version of the V-Series.R. The two cars are likely the fastest street-legal vehicles ever conceived. Unlike the Porsche, Cadillac hailed the V-One as a halo for future V-Series brand design.
“The Cadillac V-One Concept is the ultimate manifestation of a customer performance concept and is a clear sign of our ambition for the Cadillac V-Series brand in the future,” said Global Cadillac Executive Design Director Dominic Najafi before the silk was pulled off the new Caddy.
Development of a production car from a race car is hardly new at GM. The current Corvette C8 Z06, for example, was developed alongside the Corvette GT3.R race car that also competes in international sportscar racing. The Z06 shares the same, high-revving, dual-overhead can V-8 engine as the race car.
Unlike the Corvette, however, which sells 25-35,000 units a year, the V-One Concept would be a rare vehicle if produced.
“It’s about as close to the race car as you can get,” says Sean O’Shea, Cadillac Hypercar Propulsion Manager.
V-One is a notable departure from recent Cadillac concepts that had electric powertrains (the Opulent Velocity, Solleim and InnerSPace). The addition of the V-One to Cadillac’s halo arsenal alongside those concepts and the hand-built Celestiq EV indicates the continued co-existence of electric and V-8s within the brand. Not only does V-One boast an eight-cylinder engine prized by Dream Cruisers like the CT5 V-Series Blackwing road car — but it is also a hybrid. Cadillac does not sell a hybrid vehicle.
“At the heart of the V-One is a V-8 hybrid powertrain that shares foundations with the Cadillac V-Series.R race car, underscoring the concept’s serious capability and authenticity,” said the Cadillac press release of the electrified, 5.5-liter V-8. Under 37 mph, the race car operates on the electric motor before the V-8 roars to life leaving the pit lane. That duality is likely shared by the V-One.
While V-One shares the race car’s earth-shaking powertrain, it possesses significantly more power: 830-horsepower versus 670 for the V-Series.R due to so-called Balance of Performance racing regulations to encourage close racing between brands as varied as Cadillac, Porsche, Ferrari, BMW, Aston Martin, etc that compete in Hyeprcar racing with their own production-derived powerplants.
That is also true of the Corvette Z06 which produces 670 horsepower (the highest of any normally-aspirated production car) versus 500 for the GT3.R.
Other elements of the V-One closely track the race car including its carbon-fiber monocoque chassis made by the Dallara race shop in Italy, high-downforce aerodynamics, and sophisticated suspension. They also appear to share track-focused Michelin Pilot Sport slicks.
Where the V-One departs from its sibling is in its premium detailing — notably a striking silver-to-night paint job (the race car gets a vinyl wrap) and luxurious cockpit materials.
The interior is made with recycle materials, carbon-fiber trim, and a more comfortable driver’s seat (while still holding the driver in at a neck-straining 3 Gs at, ahem, 150 mph). The steering wheel is less complicated and bears a screen.
“The interior of the car is one of the main selling points with the car,” said O’Shea. “You open the doors and you look inside and it’s a clean, purpose-built race car with a bespoke Cadillac interior.”
The intention to make the car more utilitarian (the V-One engine, assures Cadillac, doesn’t require “a team of specialists just to operate”), but its track roots are still a priority. Cadillac says, despite the added luxury and weight, V-One should lap withing 10% of V-Series.R times.
A serialized plaque on the door teases Cadillac’s intention to make more copies for sale. Perhaps as a garage partner to the also- limited edition, hand-built Celestiq EV.
“(V-One) is a serious machine, but it’s amazing how we’ve been able to bring this curated design element to it to make it feel like a very special car,” said Nafaji. “The Celestiq represents ultimate luxury, the V-One represents ultimate performance.”
