A technological exhibition took place during the symposium for the launch of Honda's new dedicated hybrid vehicle. Photos showing the key technical features of the Insight are available in the "Honda Insight 2009 JDM" gallery (click HERE to visit!).
The Insight's IMA system incorporates a 14 PS electric motor, advanced battery pack, and compact Intelligent Power Unit (IPU) - recapturing kinetic energy from vehicle braking and deceleration and supplying additional power for acceleration when needed.
The IPU is composed of a Ni-hydrogen secondary battery unit, a motor driving inverter, etc. Packaging of the ultra-compact IMA battery and IPU in the vehicle's rear floor allows the enhanced utility of a 60/40 split and fold-down rear seat back. The IMA system has the capability to operate exclusively on electric power in certain low- to mid-speed driving conditions. It also provides for cylinder deactivation within the petrol engine during deceleration and shutoff when the vehicle is stopped.

本田技研工業の最新ハイブリッドカー「インサイト」。発表会において技術展示も行われており、本記事ではその展示内容を写真で紹介する。
既報のとおり、インサイトではハイブリッドシステムにパラレル方式を採用する。このパラレル方式では、エンジンをモーターがアシストし、その合成力がトランスミッションであるCVTに伝わり、適切なギア比に変換され車を駆動する。
インサイトの特長はこのパラレルハイブリッドを非常にコンパクトにまとめあげたこと。エンジンとモーターをフロントに、モーターの駆動や電力回生 の制御を行うPCU（パワーコントロールユニット）とニッケル水素（Ni-MH）のバッテリーから構成されるIPU（インテリジェントパワーユニット）を リアに配置し、システムの小型軽量化を実現している。
