Introducing FORT-EX
Ex-Core Technologies has revealed its latest breakthrough in structural carbon-fibre: FORT-EX, a one-piece subframe developed for the all-new Donkervoort P24 RS, a next-generation supercar from the Dutch manufacturer known for extreme lightweight performance and precision engineering.
At just 9kg, FORT-EX delivers racing-grade handling accuracy, crash protection, and cooling integration in a single carbon-fibre monocoque — built without metal brackets and shaped entirely through Ex-Core’s proprietary expanding-foam process.
FORT-EX forms the structural heart of the P24 RS front end, acting as:
A suspension and steering anchor
A cooling system carrier
A crash-energy absorber
A fully modular subframe, pre-assembled for rapid replacement
“The challenge was clear: make one part that integrates structure, suspension, steering and cooling — and make it both extremely light and crash-safe.”
“We even reshaped the internal aero to shrink the radiator and save 11kg.”
A New Milestone in Ex-Core Innovation
Developed originally within Donkervoort and now operating as an independent composite innovator, Ex-Core continues to push the boundaries of what structural carbon fibre can do.
Unlike traditional carbon-fibre manufacturing, the Ex-Core process enables:
Extreme stiffness for handling accuracy
Optimised crash absorption
High-frequency vibration damping
Design freedom without added mass or bracketry
Already proven in Le Mans–winning WEC cars, luxury yachts, and advanced aerospace and defence components, the FORT-EX project marks Ex-Core’s most multifunctional structural application to date — and shows how scalable this technology truly is.
FORT-EX is more than a milestone for Donkervoort. It’s proof that Ex-Core’s engineering solutions can deliver where performance, safety, and efficiency meet — in mobility, aviation, energy, and beyond.
