While the 2012 Porsche 911 isn't focused first on extracting the most mileage from its fuel, but rather on performance, style, and comfort, it nonetheless makes some interesting steps toward reducing its thirst for fuel.
Primary among these is the introduction of automatic start-stop, which shuts the car's engine down when paused momentarily and seamlessly re-starts it when it's time to head off again. Auto start-stop is standard on all new 911s. On top of that, the new 911 adds a new coasting feature, helping to further improve mileage on deceleration, but only in PDK-equipped models.
The EPA hasn't yet rated the 2012 Porsche 911's fuel efficiency, but Porsche estimates it will reach as high as the upper 20-mpg range.
