The Excalibur RS: A Handcrafted Vision of American Automotive Imagination

Handbuilt Legacy - In the modern automotive world, where retro design is often recycled and rebranded, genuinely rare creations still manage to slip quietly under the radar. Some cars are not born from factories or market demands, but from long-held ideas that refuse to fade. The Excalibur RS belongs to that quieter, more personal category—a machine that bridges imagination, patience, and craftsmanship, and only reveals its story once you slow down enough to notice its details.

At first glance, the Excalibur RS feels almost cinematic. Its elongated front nose stretches forward with purpose, while the rear is punctuated by twin short fins that give it a dramatic, almost batmobile-like silhouette. The proportions are unconventional yet deliberate, reinforcing its identity as a racing-inspired prototype rather than a conventional road car. Influences from classic endurance racers are evident, particularly in the Ford GT40-inspired front end, but the overall shape remains unmistakably its own, blending fantasy with mechanical intent.

This car traces its origins to designer Brooks Stevens, a name deeply woven into American automotive creativity. The Excalibur RS was commissioned by Bob Shaw, with contributions from Dave Draper, and conceived as a modern evolution of Stevens’ earlier Excalibur sports roadster concept from 1959. While the original RS never progressed beyond scale models, the Excalibur sports roadster became the physical realization of that vision decades later. Shaw’s commitment to the project was extraordinary, stretching across ten years and involving an investment that far exceeded practicality, driven purely by belief in the idea. 

The Excalibur RS rests on a steel tube space frame chassis built by Chuck Rahn beneath its sculpted aluminum body, which was hand-formed over more than three years to achieve both structural rigidity and lightweight precision. (Picture from: WordlessTech)

Beneath the sculpted aluminum body lies a steel tube space frame chassis built by Chuck Rahn, providing both rigidity and a lightweight foundation. The bodywork itself was hand-formed from aluminum, a process that took more than three years to complete. Every curve reflects hours of shaping rather than mass production, reinforcing the car’s status as a true one-off prototype. This slow, deliberate construction process stands in sharp contrast to today’s rapid development cycles, making the Excalibur RS feel almost rebellious in its refusal to be rushed.

Inside, the cabin balances craftsmanship with a touch of theatrical flair. Fiberglass moldings are trimmed in leather, complemented by engine-turned aluminum panels that echo classic race car interiors. A removable steering wheel adds to its motorsport character, while modern conveniences quietly blend in. The scissor doors—reminiscent of the Lamborghini Murciélago—along with the hood and deck lid, are all power-operated at the push of a button. Even the polycarbonate windshield reinforces the car’s racing roots while keeping weight in check.

Power comes from a 5.7-liter General Motors V8 crate engine, equipped with Edelbrock throttle-body fuel injection, tubular headers, and bespoke valve covers produced by Shaw’s own craftsmen. The engine is paired with a GM 700R4 automatic transmission, forming a drivetrain that prioritizes usable torque and mechanical dependability rather than chasing attention through raw performance figures alone. | qQA_2Itkp4c |

Finished in Mercedes-Benz Mystic Blue Metallic and Pearl White, punctuated by confident Brilliant Red accents, the Excalibur RS stands as a physical expression of long-term commitment rather than commercial ambition. It represents a rare meeting point between an earlier design philosophy and modern craftsmanship, shaped over years by persistence, belief, and restraint—an automotive idea allowed to mature fully before finally taking form. *** [EKA | FROM VARIOUS SOURCES | WORDLESSTECH ]
