Portugal is not a country that has ever demanded a seat at the supercar table. Its automotive industry has been, largely, an assembly story – manufacturing for others, shipping finished cars bearing other nations’ badges. Adamastor, a Porto-based outfit founded in 2010, spent its first decade doing exactly what that context would suggest: quietly building carbon fiber components for motorsport, staying in its lane, keeping its name off the finished product.
That changed with the Furia. And after a second round of high-speed testing at Portimão last week, it’s no longer a concept or a press release – Portugal’s first supercar is real, and it’s moving.
The Furia is built around a carbon fiber monocoque, and the engine sitting behind the driver is the 3.5-liter twin-turbo V6 developed by Ford Performance for the second-generation Ford GT, tuned here to produce over 650 horsepower and 421 lb-ft of torque. It is not the most exotic choice available – there will be no hand-built V12 provenance story here – but it is a thoroughly proven engine, one that has spent years demonstrating what it can do under genuine racing conditions. Adamastor has paired it with a Hewland sequential gearbox pulled directly from the motorsport world, AP Racing brakes with six-piston calipers up front and four-piston units at the rear, and fully adjustable double-wishbone suspension at all four corners. The claimed 0–62 time is 3.5 seconds, with a top speed exceeding 186 mph in road-legal configuration.
The more interesting conversation, though, is about aerodynamics. The Furia’s body is entirely carbon fiber, and its visual cleanliness – no towers of wings, no aggressive dive planes cluttering the flanks – belies what’s happening underneath. Two Venturi channels in the underbody do the heavy lifting on downforce, generating 1,000 kg at 155 mph in road specification and a reported 1,800 kg in track configuration. Against a dry weight of approximately 2,315 pounds, those numbers tell the story of a car engineered around corners rather than straight lines.
Prototype #001 returned to Portimão not for show, but for serious high-speed testing, and initial sessions produced no reliability concerns and positive feedback from test driver Diogo Matos. For a startup without decades of manufacturer infrastructure behind it, that matters considerably more than the performance figures.
The interior reflects the same uncompromising logic. The two-seat carbon tub integrates a roll bar taken directly from race car thinking, and the steering wheel looks like it belongs on an LMP grid. The starter button is mounted on the roof – which Adamastor calls a ritual – and buyers receive meaningful customization options across materials and layout, with each example hand-assembled at the Porto facility by a dedicated team.
Production is capped at 60 units, priced from €1.6 million before tax, with a Le Mans program on the longer-term horizon – the company has outlined plans for both a road-legal homologated version and a track-only configuration under the same platform.
The question that follows any new supercar brand is always the same: will it actually happen? The history of this segment is populated with beautiful renders and compelling press materials that never found their way into buyers’ garages. What separates the Adamastor story, at least for now, is that a prototype is running at speed on a real circuit without falling apart. For a company that has been building carbon fiber for fifteen years and is now applying that expertise to something with its own name on it, that is less a surprise than it might initially appear. The Furia is Portugal’s first real answer to a question the country never previously thought to ask – and on current evidence, it is a credible one.
