The General Motors XP-512H, introduced in 1969, was a remarkable glimpse into the automotive future—one that few could have imagined at the time. As part of a series of four experimental commuter car concepts, the 512H represented GM’s early exploration into hybrid-electric propulsion, decades before such technology became mainstream. The “H” in its name stood for “hybrid,” and the project demonstrated the company’s interest in developing smaller, more efficient vehicles suit

The General Motors TASC4GT, unveiled in 1972, was one of the most striking and imaginative design studies of its era. Created under the direction of GM designer Dick Ruzzin, the TASC4GT—an acronym for Total Automotive System Concept—represented a bold vision of what a future grand tourer or sports coupe could be. Also referred to internally as the GM X-Car, this concept embodied early 1970s optimism for advanced materials, new powertrains, and futuristic forms that broke away

The General Motors Micro CDS-2, introduced in 1990, was an experimental concept that explored the future of compact and efficient urban transportation. Designed by Gérard Gauvry, the CDS-2 embodied GM’s forward-thinking approach to lightweight vehicle engineering during a period when automakers were increasingly focused on fuel efficiency, reduced emissions, and urban mobility solutions. Its small size, aerodynamic shape, and advanced engine technology made it a standout in G
