The hybrid wars are heating up. In a challenge to the prevailing hybrid leader, Toyota, Honda announced it would begin selling a gasoline-electric Insight worldwide in 2009. It is estimated the price of the hybrid Insight will be below the current Prius price. In addition to Insight, Honda has several other hybrid models on the drawing board. The first gas-electric hybrid from a Detroit automaker, Chevrolet Volt, is not expected until 2010 with a considerably higher MSRP.
