Some vehicles defy categorization entirely, transcending conventional transportation to become rolling sculptures that challenge our understanding of automotive design. The 1962 Excalibur RS Roadster stands as one such creation. This extraordinary machine, preparing to cross Mecums auction block on May 16, carries exceptional craftsmanship while embodying the culmination of a design legends vision.Photo: MecumBrooks Stevens shaped American industrial design for decades, his creative genius touching everything from household appliances to transportation icons. The rugged Jeep Wagoneer, the streamlined Studebaker Hawk, and the whimsical Oscar Mayer Wienermobile all bear his distinctive touch. Stevens possessed that rare ability to infuse everyday objects with personality while maintaining their functional integrity.Genesis of a Design IconThe Excalibur RS represents something far more personal in Stevens extensive portfolioa final automotive statement conceptualized in the early 1990s but destined to remain unrealized during his lifetime.Photo: MecumThough bearing a 1962 designation that connects it to Stevens earlier works, the Roadsters story stretches across decades, bridging classic design philosophy with modern execution. This temporal duality creates something that exists simultaneously in multiple eras, refusing easy classification while demanding appreciation on its own unique terms.The RS namesake honors Robert Shaw, Stevens longtime friend who undertook the monumental task of transforming concept sketches into tangible reality. Shaw completed the vehicle in 2006, working from the designers original vision while incorporating contemporary engineering solutions.This wasnt simply a restoration or recreation but the birth of something entirely new yet spiritually connected to Stevens design language. Where most posthumous projects might attempt to rigidly adhere to original concepts, Shaw understood that Stevens genius lay in his adaptability and forward-thinking approach.Engineering the ImpossibleThe foundation of any extraordinary automobile begins with its underlying structure, and the Excalibur RS demonstrates exceptional engineering beneath its dramatic skin. Chuck Rahn developed a tubular steel spaceframe chassis specifically for this project, creating a rigid platform that supports the cars theatrical bodywork while delivering sports car handling characteristics.Photo: MecumUnlike modified production platforms that often compromise a custom vehicles performance, this ground-up approach allowed for optimized weight distribution and structural integrity without design limitations.The spaceframe constructiona technique borrowed from racing applicationsprovides exceptional torsional rigidity while minimizing mass. Every mounting point, every suspension pickup, every structural member was placed with deliberate purpose.Photo: MecumThe chassis incorporates modern suspension geometry with adjustable components, allowing the cars handling characteristics to be fine-tuned to the owners preferences. This foundation represents the perfect marriage of old-school craftsmanship and contemporary engineering knowledge.Racing-derived solutions appear throughout the underpinnings. Pushrod suspension components, adjustable anti-roll bars, and precision-machined mounting points create a platform thats as technically sophisticated as it is visually impressive.Sculptural BodyworkPerhaps nothing defines the Excalibur RS more immediately than its hand-formed aluminum bodywork. In an age of computer-designed, machine-stamped panels, the Roadsters body represents countless hours of skilled artisanship.Photo: MecumEach curve and character line was painstakingly shaped by craftsmen working with traditional tools and techniques that have largely disappeared from modern automotive production. The body draws inspiration from Stevens earlier 1961 Excalibur Hawk Coupe but incorporates thoroughly modern elements that create a unique visual identity.Photo: MecumThe most theatrical of these features are undoubtedly the Lamborghini Murcilago-style scissor doors. When opened, they transform the cars silhouette entirely, creating a dramatic entrance and exit experience while emphasizing the vehicles exclusive nature.Photo: MecumThe front end takes substantial inspiration from the legendary Ford GT40, with its low-slung profile and aggressive stance suggesting performance capabilities that match its visual drama. A low-profile polycarbonate windshield completes the race-inspired aesthetic, offering minimal wind protection in service of the cars striking appearance.The bodys proportions defy conventional automotive design rules, with an exceptionally wide stance, dramatically flared fenders, and a cockpit that appears to be carved from the surrounding bodywork rather than placed atop it. These exaggerated dimensions create a presence that commands attention without resorting to gratuitous styling elements.Photo: MecumEvery curve serves both aesthetic and functional purposes, from directing airflow to emphasizing the cars ground-hugging stance. The power-operated hood and decklid add a touch of theatrical functionality, revealing the meticulously detailed engine bay and storage area with dramatic flair.Even the smallest detailsthe custom-fabricated light housings, the precisely shaped air intakes, the flush-mounted glasscontribute to the cohesive design language that makes the Excalibur RS so visually compelling.Performance HeartBeneath the sensuous bodywork beats the heart of a serious performance machine that ensures the Excalibur RS delivers driving thrills to match its visual drama. The Roadster is powered by a 5.7-liter GM V8 crate engine equipped with Edelbrock throttle-body fuel injectiona combination that delivers approximately 500 horsepower while maintaining exceptional reliability.Photo: MecumThis powerplant was chosen for its character, providing the deep, mechanical rumble that perfectly complements the cars visceral design. The engine installation itself is a work of art, with carefully routed hoses, polished components, and custom brackets creating an underhood presentation as impressive as the exterior.Photo: MecumPower flows to the rear wheels through a GM 700R4 automatic transmission, selected for its robust construction and smooth power delivery. While purists might prefer a manual gearbox, this choice reflects the cars dual nature as both showpiece and functional vehicle, allowing the driver to focus on the experience rather than managing a heavy clutch in traffic or at events.The drivetrain represents a pragmatic approach to the cars mechanical systems, using proven components to ensure the one-off creation would be as drivable as it is displayable. This philosophycombining bespoke design with reliable mechanical componentsruns throughout the entire vehicle, creating a machine thats both aesthetically striking and genuinely usable.Photo: MecumThe Excaliburs performance credentials extend well beyond its powertrain. Wilwood disc brakes provide fade-resistant stopping power, a necessity given the cars performance potential. Power-assisted rack-and-pinion steering delivers precise control with appropriate feedback, striking the perfect balance between effort and communication.Perhaps most intriguing is the inclusion of a Halibrand quick-change rear axlea component more commonly found on race cars that allows for gearing adjustments to suit different driving conditions without major disassembly. This feature underscores the attention to detail that permeates every aspect of the Roadsters construction.Artistry in Color and DetailThe Excaliburs exterior finish is a carefully considered element of its design that enhances its dramatic form. The car wears Mercedes-Benz Mystic Blue Metallic paint, a choice that simultaneously pays homage to the 1928 Mercedes-Benz SSK while also reflecting Stevens traditional red, white, and blue color schemes that appeared throughout his career.Photo: MecumThis deep blue is accented with patriotic red and white details that create a cohesive visual statement without overwhelming the bodys sculptural qualities. The combination connects the Excalibur RS to automotive history while establishing its own distinct identity.The paints depth and metallic quality highlight the complex curves of the hand-formed bodywork, changing character as light moves across the surface. Unlike modern production vehicles with their often-flat color applications, the Excaliburs finish has a hand-applied quality that enhances its bespoke nature.Even the smallest painted detailsthe pinstriping, the accent colors, the subtle variations in finishreveal the human touch that defines truly special automobiles. Each viewing angle reveals new details, rewarding prolonged examination and appreciation.Crafted Interior ExperienceStep inside the Excalibur RS, and youre greeted by an interior that balances vintage inspiration with modern execution.
