This paper discusses the transformation in automotive technology that could accelerate the transition to transportation powered by fuel cells. The authors write that ultralight, advanced-composite, low-drag, hybrid-electric Hypercars could be three to fourfold more efficient and one or two orders of magnitude cleaner than today’s cars, yet equally safe, sporty, desirable, and affordable. Further, important manufacturing and vantages—including low tooling and equipment costs, greater mechanical simplicity, autobody parts consolidation, shorter product cycles, and reduced assembly effort and space—permit a free-market commercialization strategy. This paper discusses a conceptual Hypercar powered by a proton-exchange-membrane fuel cell. It outlines the implications of platform physics and component selection for the vehicle’s mass budget and performance. Because Hypercars would require significantly less tractive power, and even less fuel-cell power, they could adopt fuel cells earlier, before fuel cells’ specific cost, mass, and volume have fully matured. The promising performance of hydrogen-fueled PEMFC Hypercars suggests important opportunities in infrastructure development for direct-hydrogen vehicles.
