Driving the Stärke Speedster: A Modern Masterpiece Rooted in Porsche Heritage
Few automotive shapes stir the soul quite like the classic open-top roadsters of Stuttgart’s golden era. In an age dominated by digital interfaces and heavy electrification, the desire for mechanical purity remains stronger than ever. Enter the Stärke Speedster, a breathtaking custom creation that reimagines historical motorsport aesthetics using a modern backbone. Built upon the proven foundation of the Porsche 718 Boxster, this coachbuilt machine bridges the gap between vintage romanticism and everyday usability. Recently, I spent a crisp spring day carving through the winding asphalt of the Pacific Coast Highway in Malibu, putting this unique sports car through its paces to see how well its retro charm translates to the modern world.
Merging Classic Lines with Modern Engineering
The design ethos behind the Stärke Speedster draws heavy inspiration from legendary mid-engine pioneers like the 550 Spyder and 718 RSK, alongside the iconic rear-engine 356 Cabriolet. However, translating these historic curves onto a twenty-first-century footprint required an immense engineering effort. Stärke Motor Company utilized advanced 3D scanning and computer-aided design (CAD) before spending two years developing hand-laid composite body panels.
The conversion process is extensive. Builders strip away the donor vehicle’s exterior components, carefully cutting and reshaping the core structure. The front clip aligns with original factory mounting points, while customized side strakes channel fresh air directly into the Boxster’s factory intake system. The result is a vehicle that appears significantly lower, wider, and smoother than standard contemporary offerings, while maintaining a much larger and more robust presence than its vintage ancestors.

Behind the Wheel: Performance Meets Everyday Comfort
During my test drive along the sun-drenched Malibu coast, I evaluated a second-generation prototype powered by the base turbocharged flat-four engine paired with a seven-speed PDK dual-clutch transmission. While purists might dream exclusively of the screaming 4.0-liter naturally aspirated flat-six found in higher trims, the entry-level powertrain highlights the inherent balance of the chassis.
The Stärke Speedster retains the impeccable driving dynamics of its donor platform. The low center of gravity ensures that cornering remains sharp, predictable, and deeply engaging. Thanks to the meticulous assembly standards championed by Stärke CEO Seth Gortenburg, the cabin is remarkably free of unwanted squeaks or rattles. Panel gaps are uniform, and the brilliant metallic silver paintwork shimmers with exceptional depth under direct sunlight.
Unlike original vintage roadsters that demand constant maintenance, carburetor adjustments, and oil leak monitoring, this custom build offers modern luxury. Drivers enjoy functional air conditioning, reliable power-operated soft tops, and modern side windows. Furthermore, routine maintenance can be easily performed by any certified Porsche mechanic or dealership, eliminating the traditional headaches associated with owning a classic collector car.
Customization, Pricing, and Ownership Value

Stärke offers extensive personalization options for prospective buyers. The transformation can be applied to any 718 Boxster variant, ranging from the 300-horsepower base turbo-four up to the thrilling 394-horsepower GTS 4.0. Buyers can also choose between a traditional six-speed manual gearbox or the lightning-fast PDK automatic.
Pricing for this bespoke conversion starts at $135,000, or $189,000 if Stärke assists in sourcing a clean donor vehicle, prior to custom interior and exterior specifications. With production of the 718 generation officially concluding, values for clean donor cars on the pre-owned market are steadily rising, making this custom coachbuilding approach an increasingly compelling alternative to expensive, highly fragile restomods. Each completed build requires roughly six months of meticulous craftsmanship, with an approximate one-year waiting list reflecting strong enthusiast demand.
The Verdict on Modern Coachbuilding
Purists may initially question the logic of altering a modern sports car to resemble a vintage icon. Yet, by avoiding the destruction of rare, irreplaceable air-cooled classics, Stärke has carved out a brilliant niche. The Stärke Speedster successfully captures the romanticism of Porsche’s early racing history without sacrificing the safety, reliability, and comfort of a modern daily driver.
