In addition to a hybrid engine, the Insight also features another fuel-saving device. The Insight comes standard with a driver-focused fuel-efficiency enhancement technology named Eco Assist. As part of this system, pushing the dash-mounted ECON button modifies various vehicle systems to minimize the vehicle's overall energy use for increased fuel economy. A feedback system uses both ambient color behind the speedometer to indicate efficiency as you drive and an Eco Guide display that provides feedback on your braking and acceleration to help you drive more efficiently. A cumulative Eco Score scoring system provides ongoing support.
