No matter how economical a car may appear on paper, these best case scenario figures rarely translate to the real world often due to poor driving style.

To make sure all its clever fuel efficient engineering doesn't go to waste, Nissan has demonstrated its new ECO Pedal technology to keep a watchful eye over lead-footed drivers.

When the ECO Pedal system is activated, it receives data on the rate of fuel consumption and transmission efficiency during acceleration and cruising, and then calculates the optimum acceleration rate.

If the system detects excess or unnecessary pressure, it responds by pushing back the driver's foot through the pedal - but of course it can be completely deactivated.

At the same time, an eco-driving indicator integrated into the instrument panel feeds the driver with real-time fuel consumption levels to help improve their driving behaviour.

Nissan hopes to launch this new technology by as soon as 2009, with research showing the new system can improve fuel efficiency by up to 10 percent.

The new system resembles just one portion of a “triple-layer” approach by Nissan that encompasses vehicle technologies, driving behaviour and traffic conditions in the pursuit of real-world efficiency improvements.
