The Honda IMAS Concept, designed by the Wako R&D Center (HGW), was unveiled at the 37th Tokyo Motor Show in 2003. With a design philosophy centered on sustainability, human-centered functionality, and pure driving enjoyment, the IMAS exemplified Honda's vision for a lightweight, eco-friendly sports coupe. Built with an emphasis on aerodynamics and efficiency, the IMAS boasted a sleek, "One-Motion Form" crafted from composite carbon fiber that achieved an exceptionally low drag coefficient of 0.20.
Structurally, the IMAS featured an aluminum space frame paired with ultra-light composite carbon fiber panels, allowing for a remarkable balance of strength and minimal weight. Under the hood, it was equipped with a hybrid powertrain that combined an internal combustion engine with an electric motor, aimed at exceeding the performance of Honda’s Insight while also enhancing fuel economy. Astonishingly, the IMAS achieved a fuel efficiency of 80 miles per gallon, underscoring Honda's commitment to advancing hybrid technology.
Inside, the IMAS continued its high-performance theme with a minimalist, racing-inspired aesthetic. The interior featured exposed aluminum surfaces, inspired by high-performance racing bicycles, to emphasize simplicity and focus on the essentials. This stripped-down, purposeful design underscored the IMAS's sporty nature while keeping weight to an absolute minimum. The IMAS was one of Honda's notable concept vehicles that combined the brand's sporty DNA with environmental consciousness, projecting an innovative approach to future mobility.
