Nissan has designed the ECO Pedal to help drivers become more fuel-efficient. When the system is on, each time the driver steps on the accelerator a counter push-back control mechanism is activated if the system detects excess pressure. The mechanism helps inform the driver that they could be using more fuel than required. The system is fed data on the rate of fuel consumption and transmission efficiency during acceleration and cruising, and it then calculates the optimum acceleration rate. An eco-driving indicator integrated into the instrument panel feeds the driver with real-time fuel consumption levels to help improve his/her driving behavior. The ECO Pedal system can be turned on or off according to the driver’s preference. The technology makes its North American debut this spring on the 2011 Infiniti M.
