The change - likely to effect a dramatic improvement in running economy - will effect the Japanese firm's entire line-up of four-cylinder motors by 2005. 'The low emission S2000 engine was our bridge to this next generation engine, which is lighter, more compact and achieves an ultra-low emission level as well as a 20% boost in efficiency.
'In a similar way, the engine of the Insight also serves as a bridge. It breaks new ground with the efficiency of a small gasoline engine while incorporating an electric motor for improved performance. This application will reach other mass-market models,' said Yoshino. 'Through self innovation, we are challenging ourselves to make the power train of today and tomorrow cleaner and more efficient.'
