Honda "Dual Note" : 400 HP for 5.5 l/100 km fuel average
(From: http://www.salon-auto.ch/en/news/textes/visit/visit3.html)

Carrying research for ever cleaner and sober cars, Honda developed the Integrated Motor Assist (IMA) system combining an electric complementary power unit with a lean-burn petrol engine. The hybrid two-seater Insight is already marketed in Japan since two years and an hybrid version of the new Civic five-seater was recently launched.

In the same spirit but in quest of performance, Honda's engineers made a dream come true: creating an high-performance sports car with very low fuel average and emissions. The result of this research is displayed on Honda's stand at the Geneva Motorshow: the "Dual Note" concept car.

A four-door, four-seater sports car, the Dual Note is a new stunning application of the Integrated Motor Assist technology. Powered by a V6 3.5 litre i-VTEC engine assisted by three complementary electric power units (two of which driving the front wheels) it produces no less than 400 HP with a calculated fuel average as low as 5.5 litre / 100 km.

The Dual Note sums up most advanced technologies developed by Honda. First the IMA engine management system, then the active suspension with Active Torque Transfer System (ATTS) providing for better handling and the Vehicle Stability Assist (VSA) system, an highly sophisticated path control device.

Other features include infrared night vision system, 3D dashboard and voice-activated controls.
