Drivers can increase fuel efficiency by avoiding a ‘red light’ bad habit — it's not idling

Auto industry experts have explained how extra mileage can be won or lost at traffic stoplights - especially in urban areas.

Driving experts have highlighted a commonly overlooked way that drivers sharply accelerate, which, in turn, lowers fuel efficiency

The Nutley Kia auto dealership group says some drivers punch their accelerator with too much speed and force when a traffic light turns green.

These auto sales pros add that rapid acceleration at green lights separately increases vehicle wear and tear. 

Car parts that this wear and tear can affect include an engine, transmission, brake, suspension, drivetrain, and tires. 

Drivers are sometimes more likely to accelerate rapidly at green traffic lights in urban areas where motorists frequently race to get through intersections before the light changes, according to Nutley Kia.

Other drivers floor their vehicle’s accelerator under the impression that it will get them to their destination faster. 

However, the Department of Energy notes that aggressive driving, like rapid acceleration, can lower gas mileage by roughly 15 to 30 per cent at highway speeds and between 10 and 40 per cent in stop-and-go traffic. 

Motorists can further increase their fuel savings by driving with their car’s windows up at speeds greater than 45 mph.

When windows are open, air enters the main body of the vehicle, creating drag.

Drag forces your car’s engine to work harder than usual, burning more fuel than it usually would if the windows were shut.  

Drivers can also enhance fuel economy by removing certain items, like roof racks.
