While U.S. carmakers prepare for the 2009 Detroit Auto Show, Honda is readying a range of concepts to show off at the 2009 Tokyo Auto Salon, which celebrates Japan's modified vehicles. The headline concepts are a pair of Sports Modulo cars based on the S2000 and Fit (Jazz).

Modulo is Honda's Japanese-market factory customization, and the Sports Modulo S2000 Concept and Sports Modulo Fit Concept are intended to show what could be in the works for future customization packages. The aggressive and flamboyant exterior styling is matched inside both cars with upgraded materials and finishes. Little in the way of details is yet known about the two cars, though Honda has released these images. Full information will come once the Tokyo Auto Salon gets underway on January 9.

Several other concepts will be joining the Sports Modulo vehicles: a Racing Modulo Civic Type R competition car, a pair of Life and Crossroad Styling Study Models, and a range of cars and motorcycles featuring Honda's full range of upgrade equipment, audio and navigation systems and other accessories.
