With its aluminum body and frame, the Insight was an expensive car to produce and was never designed for high-volume sales. Instead, it was designed to be a real world test car for hybrid technology and a gauge to new consumer driving habits. With an aerodynamic fuel-saving shape similar to its predecessor, the Honda CR-X, and some unconventional body colors it was a bit more than mainstream car buyers could handle, preferring more conservative styles. Production halted announced in May 2006, with plans announced to replace Insight with a new hybrid car, smaller than the eighth generation Civic, but not earlier than in 2009. Ahead of this announcement, Honda stopped selling Insight in the UK, for example, as early as December 2005.
