2006 Honda GRX

American Honda Concept GRX Hybrid, an ultra-light and compact sport vehicle for the 21st century, aims at a unique synergy derived from the company’s vast experiences in both motorcycle and automotive R&D programs and manufacturing. The conceptual study model created by Honda R&D Americas, Inc. in Torrance, Calif., is powered by a 1,500cc six-cylinder, horizontally opposed engine developed for motorcycle applications.

The aerodynamic exterior and interior design inspired by a Formula racer were then carried over for the J-VX concept, an evolutionary version that made its debut at the 1997 Tokyo Motor Show. The GRX and J-VX concepts eventually led to the production Honda Insight.
