2013 Porsche 911 Carrera Convertible: Fuel Mileage Update

January 07, 2014

2013 Porsche 911 Carrera Convertible

As our 2013 Porsche 911 long-term test nears its end, the miles are still racking up nicely. We added about 2,000 ticks to the odometer with a variety of driving. Our overall mileage number bumped up slightly to 21.1 miles per gallon which is still well below its EPA estimate for combined driving.

Once again, the mileage numbers varied greatly. On the low end, we saw a tank that averaged only 16.2 miles per gallon while another tank returned nearly 24 mpg. Needless to say, with Sport mode engaged and twisty roads on the map, it's hard to keep the numbers above 20 mpg. On the highway, however, a light foot will return respectable numbers without much trouble.

Worst Fill MPG: 12.4
Best Fill MPG: 31.4
Average Lifetime MPG: 21.1
EPA MPG Rating (City/Highway Combined): 20/28/23
Best Range: 511.8 miles
Current Odometer: 22,389 mile

    I think you need to decide if the long-term average is 21.1 or 22.1. given that so much of this car's mileage was accumulated driving to NYC and back, I would say its real daily driving average would be closer to 19 mpg, which is pretty far from the EPA of 23.
