What if Porsche had stayed air-cooled?

In 1998, the factory made a decision that changed the 911 forever. The 996 arrived with a water-cooled engine — the first in the car’s 35-year history. It was the right engineering decision. But it left a question unanswered: what would the next 911 have looked like if Weissach had kept the flat-six air-cooled and simply evolved the design?

The ZGT is our answer.

This concept explores a design direction the factory never took — a 993 successor that carries the air-cooled engine forward while advancing the body, the interior, and the technology around it. The headlights stay round. The silhouette stays unmistakably 911. But the surfaces are tighter, the proportions are refined, and details like the full-width LED rear light bar and the subtle “ducktail” push the language forward without abandoning where it came from.

This is one possible answer to a question Porsche closed in 1998. We think it’s a good one.

Both the ZGT and the Gruppe 1 were designed by hand in our studio — sketched, modeled, and rendered by people, not generated by AI. That matters to us. Design is a discipline, not a prompt. Every line exists because someone decided it should.

That said — if you’ve used AI to visualize a concept of your own and want to know what it takes to make it real, we can help. Zurlinden’s engineering and ACF manufacturing capabilities can reverse-engineer from any starting point and turn it into a real, functioning car.

Gruppe 1 started the way every Zurlinden car starts — with a question.

What happens when you take the 993 platform and stop compromising? When every surface gets reshaped not for a catalog, but for a single idea? When the fenders widen because the stance demands it, the roof is rounded because the proportion calls for it, and the “Carrera” script runs along the body because the car earned it?

That’s the work we love. Not the fabrication — that comes later. The design. The hours spent studying a line, adjusting a radius, debating whether a vent reads as functional or decorative. The moment a sketch becomes a 3D model and you rotate it for the first time and it either works or it doesn’t. Gruppe 1 worked.

This car doesn’t exist yet. It’s a concept — a design study developed in our studio to push the 993 to its most aggressive expression. It may become a build. It may become something else. But the thinking behind it is the same thinking we bring to every project that comes through our door.

Design is where every great car begins. It’s what we do first, and it’s what we care about most.

Zurlinden Gruppe designs and builds complete cars.

From first sketch to finished vehicle — exterior, interior, drivetrain, chassis, every system. Our ZG-ACF autoclave carbon fiber program means we design and manufacture our own body panels. Our partner network of the industry’s finest engine builders, transmission specialists, electronics engineers, and interior craftsmen means every component meets a single standard.

One car built to your specification. Or a small production series of your own design. We have the tooling, the engineering, and the partners to scale.

Introducing the Gruppe 1 — a design study from our studio exploring the most aggressive expression of the air-cooled platform. Widened fenders, deep intakes, a dark “Carrera” script, black roof, and a full-width LED light bar spanning the tail. Everything about this car says go faster.

This is the kind of thinking we bring to every project. Yours could look nothing like this — and that’s the point.

Not all carbon fiber is created equal.

Most aftermarket carbon fiber parts are made with wet-layup or vacuum-bag processes — methods that max out at 14.7 psi of consolidation pressure, leave 2–10% void content in the laminate, and achieve only 40–55% fiber volume fraction. They look like carbon fiber. They don’t perform like it.

ZG-ACF parts are autoclave-cured prepreg — the same process used by Formula 1, aerospace, and Porsche Motorsport. 85–100+ psi of consolidation pressure. Under 1% void content. 60–70% fiber volume fraction. Every part 3D-scanned from a factory Porsche original, verified with prototypes, and produced from CNC-machined molds to OE tolerances.

The difference isn’t cosmetic. It’s structural.

Swipe through to see how ZG-ACF compares to typical aftermarket carbon fiber, why autoclave curing matters, and the 7-step process from 3D scan to finished part.

Hood. Roof. Deck lid. Direct bolt-on fitment. No filler. No modification.
