Nissan to install fuel-efficiency gauge in all its models

Automaker Nissan announced plans yesterday to install a gauge in all its vehicles that estimates fuel-efficiency to let drivers know how their driving habits affect gas mileage. The gauge already appears in some of Nissan’s newest luxury cars, but its plan to eventually showcase the efficiency meter in every model has drawn praise from greens. “It shouldn’t be just wealthy people with luxury cars that have this information,” says Tim Carmichael of the Coalition for Clean Air. “I hope the rest of the industry follows them.” It’s been estimated that the new information could influence drivers to be an average of 10 percent more fuel-efficient. Now if only they’d put an indicator in every vehicle to show drivers how much fuel they’d save by not driving.
