Eco Score
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
The Eco score is a fuel economy average calculated from real-time driving information, idle time evaluation, and the percentage of time the ECON button is on. The Eco score determines how many points (parts of the plant icon) are awarded on the Eco guide. Calculation of the Eco score begins when the ignition is turned to ON (II), and continues while the ignition is in ON (II). The Eco score begins to display on the Eco guide after 3 minutes of engine idling or 218 yards of driving. The calculation logic changes for each Eco stage, making it progressively harder to score points.
