The new device has been dubbed ECO Pedal. Nissan says when the system is on, a push-back mechanism will be activated, letting drivers know when they're using more fuel than might be needed for the situation. Like the old shift lights on Audis and other cars, the "Eco" light on the dash that accompanies the ECO Pedal will help drivers learn how to use less gas and to cut on fuel bills, Nissan says.
Thankfully the whole shebang can be turned off. Nissan does promise that it can help boost fuel economy by 5 to 10 percent, depending on how faithful drivers are to using the green light to retrain their feet. The company plans on offering the device sometime in the 2009 model year, but hasn't said on which models or in which countries--and it's likely our lawsuit-happy nation is low on the priority list.
