2013 Porsche 911 Carrera Cabriolet Long-Term Road Test

2013 Porsche 911 Carrera Cabriolet: Fuel Economy Update for February

March 4, 2013

2013 Porsche 911 Carrera Cabriolet

During the month of February we drove our 2013 Porsche 911 Carrera Cabriolet about 940 miles. During those almost-four weeks the sedan averaged 15.4 miles per gallon of 91 octane premium.

That's quite a bit lower than the 16.7 mpg that we've averaged over the car's 2,214 miles and the Porsche's 21.5 mpg combined EPA rating. The reason? Hard driving. The Porsche saw particularly spirited use this month and was also track-tested, where the throttle is used with impunity, eroding its fuel economy.

It's still early in the Porsche's test, so a few hard-driven fills make an unduly strong impression on the average to date. Once we throw in a few long trips we'll get a more complete picture of the 911's fuel-using ways.
