Gunther Werks Unveils One-Off ‘Project Endgame’ Turbo Speedster

In the rarefied world of bespoke automotive craftsmanship, finales carry as much weight as firsts. With the unveiling of Project Endgame, Gunther Werks delivers both – a definitive closing statement on its acclaimed Speedster program and the opening chapter of an even more exclusive future. Conceived as a true one-of-one commission, Project Endgame represents the ultimate evolution of the Gunther Werks Speedster, distilling nearly a decade of engineering refinement into a singular, open-air machine. More than a culmination, it also introduces GWX, the marque’s new bespoke coachbuilding program, designed to push the boundaries of personalization and craftsmanship to unprecedented levels. The car will make its public debut at the Air|Water event in Costa Mesa on April 25, 2026, before being exclusively displayed at the museum by the Natsukashii Foundation. For collectors and enthusiasts alike, it represents a rare opportunity to witness a singular creation – one that encapsulates the ethos of Gunther Werks at its most extreme. “Project Endgame is unlike any Speedster we’ve built before, with every element precision-engineered and designed in absolute collaboration with the client,” said Peter Nam, CEO and founder of Gunther Werks. “Even the most granular details were taken into account and refined. In this case, performance was paramount. At the client's behest, Endgame will be the only Speedster powered by an air-cooled turbocharged engine, undoubtedly making it our fastest Speedster to date.” At its core lies a formidable powertrain that underscores that performance-first mandate. Built by Rothsport Racing, the 4.0-liter twin-turbocharged flat-six produces 840 horsepower and 660 lb-ft of torque. Revving to 7,500 rpm, the motorsports-derived engine channels its output to the rear wheels through a six-speed manual gearbox with bespoke ratios, delivering both immediacy and precision. A flat-fan system – an homage to Porsche motorsport – ensures even cooling across all six cylinders, while twin air-to-water intercoolers, plated in 24-karat gold, highlight the fusion of performance engineering and artisanal detail. That philosophy extends seamlessly to the exterior. The carbon-fiber bodywork, shaped for aerodynamic optimization, retains the timeless silhouette of the Porsche 993 while incorporating enhancements derived from the Gunther Werks Turbo. Newly developed rear quarter panels accommodate the enlarged turbocharged engine, contributing to what is now the highest power-to-weight ratio of any Gunther Werks commission. At just over 2,600 pounds, Project Endgame pairs immense output with lightness. Visually, the car is as dramatic as it is deliberate. Finished in a bespoke True Candy Red – a process requiring three weeks to complete – the widened and channeled carbon body is accented by 24-karat gold mirror and headlight bezels. These details underscore the level of personalization now possible under the GWX program, where materials, finishes, and design elements are tailored without constraint. Inside, the same obsessive attention to detail defines the experience. Carbon fiber surfaces are complemented by dyed leather and Alcantara, alongside gold and Satin Stealth plating. Even the gear lever becomes a centerpiece, wrapped in 24-karat gold and set with six gems arranged in a 1-6 pattern, transforming a functional component into an object of artistry. Project Endgame is, by design, both a conclusion and a beginning. It marks the final expression of the Speedster lineage while simultaneously introducing GWX as a platform for future one-of-one commissions – each limited only by the imagination of its client. In doing so, Gunther Werks reinforces its position at the intersection of high-performance engineering and modern coachbuilding, where exclusivity is defined not by volume, but by individuality.

Gunther Werks Reveals Latest Turbo Commission Inspired by a Greek Mythology Disney Character

Gunther Werks Reveals Latest Turbo Commission Inspired by a Greek Mythology Disney Character

Gunther Werks unveiled its latest Turbo-based commission, dubbed “Hercules”. Showcased via a recent post on Instagram, this latest build draws inspiration from the legendary character and the protagonist in Disney's 1997 animated film, based on the Greek mythological hero. The exterior features a color-shifting finish that transitions between deep red and brown depending on lighting. The interior draws from Hercules’ iconic blue cape, which serves as a contrast against the earthy tones of the exterior. Blue accents run throughout the cabin, while brown leather covers primary surfaces. Alcantara has been used on high-contact areas for grip, while the dash includes a custom trim panel featuring subtle Greek-inspired detailing. View this post on Instagram A post shared by Gunther Werks (@guntherwerks)   Power comes from a Rothsport Racing-built 4.0-liter twin-turbo flat-six that produces 840 horsepower, while a full carbon fiber composite body keeps curb weight just over 2,750 pounds, offering up a power-to-weight ratio of 0.305 hp/lb that places it in hypercar territory. For some context, that is Bugatti Chiron territory. Based out of Huntington Beach in Southern California, Gunther Werks continues to evolve its lineup predominantly based on the 993 platform.  Built in extremely limited numbers to maintain exclusivity, these cars are highly bespoke with extensive customisation options. The Coupe and Speedster programs are both limited to just 25 units. The F-26 program, with over 1,000 horsepower and 935-inspired styling, is limited to 26 units, whereas the GWX program remains capped at just three examples. The GW9 offers an eight-piece precision-crafted carbon fiber aero kit for the 992.1 Turbo S. These cars seldom come up for sale, but a GW Speedster dubbed “Mystique” is currently up for auction on duPont REGISTRY Live (If you're interested in financing this car or another exotic car, be sure to get pre-qualified). What makes it particularly desirable is that Porsche itself never pursued the Speedster bodystyle for the 993 generation as a series production model. A one-off Sonderunsch commission for Porsche collector Luca Trazzi, shown at the Quail in 2024, pursues this unique configuration. View All Gunther Werks For Sale  Images: @guntherwerks
