Check out the Honda Insight section on Honda Japan’s website and you’ll be greeted by the teaser image above, which seems to indicate that an Insight with a larger 1.5 liter i-VTEC IMA engine will be available soon. So far, most Honda hybrids including the Honda Insight sold here in Malaysia use the 1.3 liter system, while the 1.5 liter system is reserved for the sporty Honda CR-Z.A larger more powerful system in the Insight would certainly be welcome for those looking for a little more fun in their green motoring, but do not want to go for the 3-door body of the CR-Z. With the hybrid tax exemptions just recently extended by the Malaysian government, perhaps Honda Malaysia can introduce this 1.5 liter variant of the Honda Insight as well? I’m sure there’s a market!
