Gunther Werks Reveals ‘Project End Game’, Its Final Speedster Build

California-based Gunther Werks has unveiled Project End Game, a one-off Speedster based on the Porsche 993.

This model marks the end of Gunther Werks’ Speedster program and also introduces its new GWX coachbuilding division. It is a one-of-one build, created as a final showcase after nearly a decade of development.

What It Is

Project End Game is a fully custom Speedster derived from the Porsche 993 platform, reworked extensively by Gunther Werks.

• One-of-one commission
• Final Speedster from Gunther Werks
• Based on the Porsche 993
• First model under the new GWX program

It brings together the brand’s engineering and design work into a single final car.

Engine and Performance

The car uses a heavily upgraded engine setup built with racing input.

• 4.0-litre twin-turbo flat-six engine
• 850 hp and 660 lb-ft torque
• Rev limit of 7,500 rpm
• Six-speed manual gearbox
• Rear-wheel drive

Despite the high power, the car remains lightweight, weighing just over 2,600 lbs.

Lightweight Focus

Weight reduction is a key part of the build.

• Full carbon-fibre body
• Removal of unnecessary components
• Focus on improving the power-to-weight ratio

This makes it the most performance-focused Gunther Werks Speedster so far.

Design Approach

The design stays close to the original Porsche 993 shape while adding modern performance elements.

• Retains the classic 993 silhouette
• Carbon-fibre panels for aerodynamic efficiency
• Open-top Speedster layout
• Clean, performance-focused styling

The colour and finish of this particular build also stand out, with a combination that gives it a look similar to Iron Man’s suit, adding a distinct visual identity to the car.

Interior and Build

The interior is fully customised for this single car.

• Bespoke materials and finishes
• Custom trim and detailing
• Built in-house by Gunther Werks’ team in California

Every part of the cabin is tailored specifically for this build.

Conclusion

Project End Game is a final statement from Gunther Werks’ Speedster line.

Based on the Porsche 993, it combines classic design with modern performance, while also setting the stage for the brand’s next phase in bespoke car building.
