2026 Gunther Werks Project Endgame
By Lorenzo Bianchi April 23, 2026
One off Speedster marks the end of the Gunther Werks program.
4.0L twin turbo flat six with 850 hp and manual gearbox.
Lightweight carbon body with over 2,600 lbs total weight.
A final Speedster shaped with intent
The 2026 Gunther Werks Project Endgame doesn’t arrive as just another commission. It feels like a closing statement.
Visually, it stays close to the familiar 993 silhouette, but the execution is far from nostalgic. Every surface is reworked in carbon fiber. Panels sit tighter, cleaner, more deliberate. There’s a sense that nothing has been left untouched, even if the overall shape remains instantly recognizable.
Being an open air Speedster, the proportions carry that low, cut-back profile. It looks compact, but not delicate. More like something condensed and sharpened over time.
Compact form, pushed toward performance
The stance tells its own story.
This is still based on the 993 footprint, but the balance has shifted. With extensive carbon fiber use, the total weight sits just over 2,600 pounds. That alone changes how the car sits on the road. It looks planted, almost dense, despite the relatively small size.
There’s also a clear focus on aerodynamics. Each panel isn’t just shaped for appearance. It’s been adjusted to manage airflow more efficiently, even within the constraints of a classic outline.
Cabin remains bespoke and tightly focused
Interior details are largely bespoke, tailored specifically for this one build.
Gunther Werks hasn’t outlined every element, but the direction is clear. Materials, trims, and finishes are unique to this commission, developed in collaboration with the team in California.
Given the open air layout, the cabin is likely to feel exposed but intentional. Less insulation, more connection. That fits the overall character of the car.
A powertrain that defines the project
The numbers stand out immediately.
At the core sits a Rothsport Racing built 4.0 litre twin turbocharged flat six. Output is rated at 850 horsepower with 660 lb ft of torque. The engine revs to 7,500 rpm and sends power to the rear wheels through a six speed manual gearbox.
That combination feels deliberate. High output, but paired with a manual. It keeps the experience grounded, even with the performance figures pushing far beyond the original 993’s limits.
Gunther Werks also notes that this car achieves the highest power to weight ratio of any of its builds to date.
Built for experience, not just specification
Practicality isn’t really the focus here, but usability hasn’t been ignored entirely.
The open air format and relatively low weight suggest a car designed for direct engagement rather than long distance comfort. It’s the kind of setup that prioritizes response, sound, and immediacy.
There’s also the broader context. This isn’t a series production model. It’s a one off, created as the final entry in the Speedster program.
Positioning as a closing chapter
Project Endgame sits in a unique position.
It marks both the end of Gunther Werks’ Speedster line and the beginning of something else. The car introduces the GWX program, which shifts focus toward fully bespoke, one of one builds.
In that sense, this car isn’t just about performance or design. It acts as a transition point. A final look at what the brand has been doing for nearly a decade, and a hint at where it’s going next.
There’s a certain restraint in how it’s presented. No excess messaging. Just a clear idea. Build the most complete version of the Speedster possible, then stop.
