Review: Porsche 718-Based Stärke Speedster – A Modern Classic Reborn
Introduction to the Stärke Speedster
For enthusiasts who adore the romance of vintage roadsters yet demand the reliability of modern engineering, the Stärke Speedster offers an extraordinary proposition. Built upon the robust foundation of the Porsche 718 platform, this custom creation bridges the gap between classic design and contemporary performance. Far from being a typical restomod, the Stärke Speedster utilizes advanced coachbuilding techniques to capture the aesthetic magic of legendary models like the 550 Spyder and 356 Cabriolet, while retaining everyday usability, comfort, and modern safety standards.
Engineering and Design Philosophy
When custom coachbuilder Stärke Motor Company debuted its second-generation prototype, automotive purists immediately took notice. Rather than cutting up rare vintage chassis, the team selected the modern mid-engine 718 Boxster as the core architecture. Achieving this seamless retro transformation requires a meticulous, two-year development process involving advanced 3D scanning, CAD renderings, and hand-laid composite body panels.

The exterior showcases a low, wide stance reminiscent of early motorsport pioneers. Custom “Wide Five” wheels mimic original Porsche steelies, while the front clip utilizes factory mounting locations for structural integrity. Buyers can choose between standard fiberglass or optional carbon fiber panels, which shed hundreds of pounds and sharpen the driving dynamics even further.
Performance and Driving Dynamics in Malibu
Behind the wheel along the scenic Pacific Coast Highway in Malibu, the vehicle reveals its true character. Powered by options ranging from the standard turbocharged four-cylinder to the sublime 3,948-cc naturally aspirated flat-six in the GTS 4.0, the car maintains the exceptional handling balance inherent to Stuttgart’s engineering.
During test drives, the metallic silver finish demonstrated flawless panel alignment and a complete lack of rattles or chassis flex. Whether paired with a six-speed manual gearbox or the lightning-fast seven-speed PDK dual-clutch transmission, the driving experience marries old-school thrills with modern convenience—complete with functional air conditioning, power tops, and responsive power steering.

Customization, Pricing, and Market Value
Because the 718 generation concluded its production run, the market for donor vehicles remains active and strong. Stärke offers extensive personalization, allowing clients to tailor everything from exterior paint finishes to cabin upholstery, such as iconic Pepita houndstooth inserts or rich Boxster Red leather.
Pricing starts at $135,000 for the conversion work alone, or approximately $189,000 when Stärke assists in sourcing a pristine donor car. With each handcrafted build requiring roughly six months of labor and rigorous shakedown testing, the final product delivers an exclusive open-air driving experience that respects Porsche heritage while offering modern daily drivability.
Conclusion and Next Steps
The Stärke Speedster proves that modern coachbuilding can successfully honor automotive history without sacrificing mechanical reliability.
