Molzon Corsa GT38 Concept: A One-Off Vision of Classic Performance and Innovation

Steel Imagination - For decades, classic cars have often been boxed into a stereotype—beautiful, yes, but technologically outpaced and overshadowed by modern performance machines. Yet every so often, a creation emerges that quietly challenges that assumption, blending timeless aesthetics with forward-thinking engineering. One such machine is the Molzon Concept Corsa GT38, a rare, one-off creation that feels less like a relic of the past and more like a bold personal statement from an era defined by experimentation and ambition.

The story of the car begins with William “Bill” Molzon, a designer shaped by his experience at General Motors, where he worked alongside influential figures on some of Chevrolet’s most iconic models. Unlike many designers whose ideas remain confined to sketches or corporate projects, Molzon pursued something far more personal. In 1963, he set out to build a car that embodied his own vision entirely—one that could accelerate faster than the quickest Corvette of its time, match the fuel efficiency of a Corvair, and deliver the agile handling associated with lightweight European sports cars.

To bring that vision to life, Molzon engineered a lightweight space frame chassis constructed primarily from one-inch steel tubing. The structure featured a compact 90-inch wheelbase and a semi-monocoque front section, reflecting both careful planning and early experimentation—he had even tested a scale version of the frame while still in college. Suspension design was equally thoughtful, with unequal-length wishbones and anti-dive geometry at the front, and a sophisticated rear setup incorporating inverted A-arms, twin trailing arms, and anti-squat characteristics. The goal was clear: balance, control, and responsiveness, all wrapped into a compact footprint.

At the heart of the GT38 sat an air-cooled Chevrolet Corvair flat-six engine, chosen for its lightweight aluminum construction and capable of producing around 200 horsepower. Positioned in a rear-mid layout just behind the cockpit, the engine contributed to an ideal weight distribution. Pairing it with a suitable transmission proved challenging, but Molzon ultimately adapted a 5-speed manual transaxle from an early Porsche 901—later known as the 911—modifying it to work seamlessly with the Corvair engine. This combination reflected not only ingenuity but also a willingness to bridge American and European engineering philosophies.

The car’s exterior tells a story of evolution. Initially conceived with sharper, wedge-like lines, the design gradually softened into a more fluid, curvaceous form to improve aerodynamics. Molzon sculpted the body using carved Styrofoam blocks based on full-scale drawings, refining each surface before laying fiberglass over the form. By the summer of 1967, the body was complete, and with the interior and electrical systems installed, the GT38 was ready to meet the world—though it largely remained a personal treasure. Kept for five decades and driven sparingly, the car resurfaced publicly only in 2017, offering a glimpse into a deeply personal project that never sought mass production but instead captured the spirit of one designer’s uncompromising vision. *** [EKA [30122019] | FROM VARIOUS SOURCES | BONHAMS | SILODROME | GATSBYONLINE | ]
