insight: the world's lowest
fuel consumption* technology
Honda's IMA system, an ultra-aerodynamic shape and a new lightweight aluminum body structure are at the heart of the insight's unheard-of low fuel consumption.
Honda's IMA (Integrated Motor Assist) system is a proprietary hybrid system that combines a 1.0-liter lean-burn VTEC engine with a motor assist mechanism to provide superior fuel combustion in all driving situations.
World-leading aerodynamics in a mass-produced vehicle for dramatically reduced aerodynamic resistance.
Honda's new lightweight aluminum body structure employs a structural design and forming technologies that take full advantage of aluminum's intrinsic qualities to achieve both high rigidity and lightness.
Technologies that reduce weight and improve efficiency have also been adopted in the transmission and chassis to achieve a minicar-like weight of 820kg (model equipped with a 5-speed manual transmission), and the world's lowest fuel consumption* for a gasoline engine-powered vehicle of 35km/liter (using a model equipped with a 5-speed manual transmission).

*As of October 1, 2000.
