Drivers that try and push their cars to the limit, could find they start to push back.

Nissan Motor Co’s ‘ECO Pedal’ system, promoted as both green and safe – makes the accelerator pedal press upwards when it senses motorists are speeding up too quickly.

The system, which Nissan says will be available next year, calculates the most efficient rate of acceleration in a vehicle based on how fast fuel is being burned among other factors, when it deems the motorist is exceeding the most efficient rate, the accelerator pedal pushes back. A meter on the dashboard flashes and changes colours to alert the driver.

According to Nissan, the system is designed to help drivers become more fuel efficient; implementing it could help drivers improve fuel efficiency by five to 10 per cent.

There is an option for switching the system off.
