How important is hybrid propulsion vs. other technologies to the Insights efficiency?
One of the ways in which the Insight is most misunderstood is in thinking of it simply as a hybrid gas-electric car. Hybrid propulsion is only one of a number of significant technological advancements incorporated into this remarkable car. Compared to a similarly sized 1.6L 3-door Civic, the Insight consumes only 54% as much fuel over the same distance, and so also produces only 54% as much greenhouse gas.
