The Coolest Advantage in Driving the P24 RS
Thursday 08/05/2025:focal())
Air, redefined.
Donkervoort delivers a cutting-edge thermal breakthrough for the upcoming P24 RS supercar, developed in collaboration with thermal pioneers Conflux–a new generation of 3D-printed, ultra-lightweight water-charge air coolers.
The second Engineering Chapter in the P24 RS: Living the Drive series reveals how Donkervoort and Conflux have redefined the air cooler—delivering a system that is lighter, smaller, and more efficient than anything previously seen in production cars.
The result: a pair of aluminium-alloy sculptures weighing just 1.4 kg each, compared to 16 kg for conventional air-to-air units with similar thermal capacity. These custom water-charge air coolers (WCAC) provide sharper throttle response, improved packaging, and reduced weight.

F1-grade solutions
“The key to engine performance is keeping the intake air as cold as possible,” said Managing Director Denis Donkervoort. “We challenged ourselves to find the best way to achieve that—and Conflux delivered.”
“We moved to a liquid-to-air cooler, made using additive manufacturing, from a company that isn’t just on the cutting edge—they’re ahead of it. We gave Conflux our exact specifications, and they delivered a solution so effective, we could even downsize it from the original prototype.”
Thanks to their compact form, the air coolers now sit within the engine bay rather than at the front of the car—reducing the inlet-tract length of the outgoing engine by two-thirds. The result: quicker response, greater efficiency, and optimised weight distribution.
These Conflux units—designed and built in Australia—join Van der Lee’s billet turbochargers as part of Donkervoort’s high-tech evolution of the PTC engine.
Water is cooled through a bespoke external radiator, then redirected to chill the intake air before it enters the combustion chamber. That precision enables consistent, high-performance delivery—under any condition.
“Our Formula 1 technology is available beyond the track for the first time,” said Conflux Founder Michael Fuller. “We’re scaling it for the high-performance automotive market. For limited-production vehicles like the P24 RS, F1-grade solutions are finally within reach.”
3D-Printed. Driver-Focused.
Donkervoort was among the first to adopt Conflux’s production-ready air coolers, utilising cylindrical designs placed directly between the turbochargers and throttle bodies of the PTC engine. Each component is 3D-printed with tailored fin geometry, density, and size, grounded in engineering-first principles.
“Donkervoort approached us with clear cost and performance targets,” Fuller added. “Their clarity and drive made this one of our most exciting collaborations. Within our configurable product line, we could fine-tune everything—from diameter and fin density to overall length—for the most efficient design possible.”
The system also integrates a custom-sized, thin-wall radiator that provides more cooling with less coolant and a smaller surface area than its predecessor.
Together, Donkervoort and Conflux didn’t just rethink cooling. They re-engineered how performance breathes.

About Donkervoort
Established in 1978 by Joop Donkervoort and now led by his son, Denis, Donkervoort Automobielen has sold approximately 1,700 cars. Operating from Lelystad, the Netherlands, with a team of more than 50 specialists, the company first gained widespread acclaim with the D10 in 1988, setting a world acceleration record. This was followed by the D8 270 RS in 2005, which set a Nürburgring lap record.
The F22, further integrating its patented Ex-Core carbon fibre technology, achieved an astonishing 2.3g of lateral acceleration at Circuit Zandvoort, exceeding the D8 GTO-JD70’s already impressive 2.1g benchmark. This milestone highlights Donkervoort’s relentless pursuit of performance and innovation.
Dedicated to crafting exclusive supercars fully tailored to their drivers’ preferences and ensuring the purest driving experience—whether an unfiltered connection to the road or track or a more refined balance of comfort and performance—the brand continues to embody the 'Living the Drive’ ethos. Looking to the future, Donkervoort has unveiled a new model, further reinforcing the brand’s bold evolution and unwavering commitment to innovation.
