Percentage of vehicles with eco-driving support systems

We equip many of our models with tools for helping drivers apply fuel-efficient driving techniques. In addition to fuel economy meters and other eco-driving support systems, we have been installing our Ecological Drive Assist (Eco Assist)2 system in a growing number of vehicles. This system is designed to help drivers improve their fuel efficiency by providing real-time feedback on their car operation and also optimally controlling air conditioning and other systems. In fiscal 2013, eco-driving support systems were installed in 99.0% of Honda passenger cars sold in Japan, with 75.1% of vehicles featuring an Eco Assist system.

  1. The Eco Assist system works in multiple ways. In "Econ" mode, priority is given to fuel economy, and the vehicle automatically controls the engine, motor, CVT, and air conditioning system to effectively improve fuel efficiency. It also includes a coaching function, which changes the background color of the speedometer according to how efficiently acceleration and braking are applied, and a coaching function that shows the driver's eco-driving score.
