2012 Mercedes-Benz SLS AMG Roadster: Fuel Economy Update for July

August 2, 2013

2012 Mercedes-Benz SLS AMG Roadster

Even without any official road trips, our 2012 Mercedes-Benz SLS AMG Roadster went nearly 1,700 miles in the month of July. Apparently, we really enjoy driving the SLS. It has used approximately 150 gallons of 91-octane fuel over the last 30 days and we hit an mpg milestone. Can you guess what kind of milestone it was?

The SLS AMG clocked its worst mpg on record this month, averaging 7.3 mpg for one tank of fuel. This milestone, compared to the milestone our Benz achieved in June when we recorded our best fuel economy yet (24.7 mpg) shows the wide range of real-world fuel economy you can expect based on your driving habits.

However, even with our heavy feet, we're still within 1 mpg of the EPA's 16 mpg combined estimate over the life of the car.

Worst Fill MPG: 7.3 mpg
Best Fill MPG: 24.7 mpg
Average Lifetime MPG: 14.9 mpg
EPA MPG Rating: 16 Combined (14 City / 20 Highway)
Best Range: 415.9 miles
Current Odometer: 28,350 miles
