Driving the Stärke Speedster: A Modern Marvel Built on Porsche 718 Engineering
The intersection of vintage aesthetic charm and contemporary engineering has always captivated automotive enthusiasts, but few coachbuilders bridge that gap as seamlessly as the Stärke Speedster. Unveiled in its second-generation prototype form at the Southern California Air|Water event, this custom machine reinterprets Porsche’s most romantic historical roadsters. Rather than cutting up a rare classic or building a fragile restomod, Stärke Motor Company utilizes the robust, high-performing foundation of the modern Porsche 718 Boxster platform. For driving purists looking for the ultimate modern sports car experience wrapped in legendary mid-century styling, this creation offers a fascinating proposition.
Spending a crisp spring morning evaluating the prototype along the Pacific Coast Highway in Malibu provided the ideal environment. Flanked by the ocean breeze and winding coastal tarmac, the vehicle immediately channels the sun-drenched spirit of early motorsport icons while delivering the reliable comfort of a twenty-first-century daily driver.
Design Heritage and Coachbuilding Craftsmanship
At first glance, the Stärke design pays clear homage to foundational Porsche models like the legendary mid-engined 550 Spyder, the 718 RSK, and the classic rear-engined 356 Cabriolet. However, static photography fails to capture its physical presence. Stamped with a wide, low, and smooth stance, the Speedster occupies a substantially larger footprint than its vintage ancestors. Details like the custom “Wide Five” wheels serve as direct visual nods to original Porsche steelies, blending historical reverence with modern wheel and tire tolerances.
Transforming a 718 Boxster into a Stärke Speedster is no superficial body kit exercise. The process demands intensive 3D scanning, precise CAD modeling, and two years of development to engineer hand-laid body panels. To mount these components, technicians must strip away much of the factory outer shell, removing the doors and rear quarter panels. The front clip utilizes factory mounting locations, while inner fenders bond structurally to the rear quarters to maximize chassis rigidity. Side strakes are meticulously integrated to feed the Boxster’s original engine air intakes seamlessly.
Engineering Standards and Driving Dynamics
Purists may initially question the validity of grafting vintage lines onto a modern mid-engine roadster. Yet, any skepticism regarding build quality vanishes the moment you step inside. Coming from an American hot-rodding background, CEO Seth Gortenburg prioritizes structural integrity and mechanical refinement. The metallic silver paintwork boasts an incredible depth of finish, panel gaps align with factory precision, and the cabin remains free of creaks, rattles, or loose trim over broken pavement.
Stärke can apply this transformation to any variant of the 718 Boxster lineup:
Base Model: Features a responsive 300-horsepower turbo-four engine.
Boxster S: Steps up performance with 350 horsepower.
GTS 4.0: Delivers a spine-tingling 394 horsepower via an aggressive 7,800-RPM naturally aspirated flat-six.
Buyers can select either a traditional six-speed manual transmission or a lightning-fast seven-speed PDK dual-clutch automatic. Because the fiberglass body weighs roughly the same as the donor car, the iconic handling balance of the Porsche 718 remains completely intact. The low center of gravity makes twisty canyon roads an absolute joy, offering agile cornering without sacrificing highway compliance.
Practicality Meets Vintage Romance
One of the greatest advantages of using a modern donor vehicle is everyday usability. Unlike true vintage classics that suffer from erratic carburetors, unreliable electrical systems, and constant fluid leaks, the Stärke Speedster features modern climate control, power windows, and a reliable power top.
During our Malibu evaluation drive, the primary functional consideration involved the low front ride height and extended front overhang. Navigating steep driveways and aggressive speed bumps requires mindfulness, a trait amplified if buyers select the optional carbon fiber bodywork. While the carbon upgrade sheds hundreds of pounds to enhance agility further, the standard fiberglass option provides an optimal balance of durability and weight.
Maintenance is similarly stress-free. Any certified Porsche technician or specialty mechanic can service the mechanical systems using standard diagnostic tools, ensuring long-term ownership peace of mind.
Customization, Pricing, and Market Positioning
Stärke streamlines the commission process by assisting clients with sourcing donor vehicles and interior trims. Base pricing for the conversion starts at $135,000, or $189,000 inclusive of a sourced donor car, before personalized bespoke options. Given that Porsche concluded 718 production recently, pre-owned values for donor platforms remain strong, reinforcing the long-term collectibility of these bespoke builds. Each vehicle requires approximately six months of meticulous handcrafting, resulting in a current waiting list of around one year.
While traditionalists might favor unaltered classics or pure factory configurations, the Stärke Speedster carves out a unique niche. It successfully delivers the breathtaking aesthetic of Porsche’s golden era combined with the safety, comfort, and performance of a modern sports car.
