Honda Dualnote

The Honda Dualnote (also branded as the Acura DN-X) is a hybrid sports car concept that was initially unveiled at Japan's Tokyo Motor Show in 2001.

The Dualnote was powered by a 3.5 L double overhead camshaft (DOHC) i-VTEC V6 motor with Honda's Integrated Motor Assist electric hybrid system. This engine setup was estimated to produce 400 hp while still being capable of fuel efficiency of approximately 18 km/L (5.6 L/100 km).
