2009 Honda Insight Hybrid Official Specs

The hybrid drivetrain is matted to a continuously variable transmission (CVT). As with the IMA, the Insight utilizes a set of batteries to store the energy that would otherwise be lost during braking. The energy is then used to power the electric motor. Honda claims that the Insight achieves a combined fuel consumption in the European test cycle of 4.4 liters per 100 km (53.5mpg US) with CO2 emissions of only 101 g/km.
