The Honda Dualnote (also branded as the Acura DN-X) was a hybrid sports car concept that was initially unveiled at Japan's Tokyo Motor Show in 2001.
The Dualnote was powered by a 3.5L double overhead camshaft (DOHC) i-VTEC V6 motor with Honda's Integrated Motor Assist electric hybrid system. This engine setup was estimated to produce 4000NaN0 while still being capable of fuel efficiency of approximately 18km/L (5.6 L/100 km).[1]
It has appeared in Gran Turismo Concept up until Gran Turismo 6. It has not appeared in the Gran Turismo series since.
