TOKYO (Reuters) - Nissan Motor Co said on Monday it has developed an accelerator pedal that can push back on the driver’s foot when it detects excess pressure and poor fuel efficiency.

Japan’s No.3 automaker said it would install the “ECO pedal”, which can be switched on or off by the driver, in its cars from next year. It didn’t specify which models would be equipped with the new technology.

Internal research showed that the system, which comes with real-time fuel consumption levels displayed in the instrument panel, could improve fuel efficiency by 5-10 percent depending on driving conditions.

Nissan is taking a three-pronged approach to reducing carbon dioxide emissions, comprising improvements in vehicle technologies, driving behavior and traffic conditions.

Last year, it promised to equip all new cars with the fuel consumption indicator, which indicates the optimal level for fuel-efficient driving by displaying a green, flashing or amber light.
