2012 Mercedes-Benz SLS AMG Roadster: Road Trip Fuel Mileage

March 21, 2013

2012 Mercedes-Benz SLS AMG Roadster

In just 51 hours and 11 minutes spread over five days, we drove our long-term 2012 Mercedes SLS AMG Roadster from Santa Monica to Mount Rushmore and back. And we averaged 18.5 mpg doing it. The EPA rates the SLS at 20 mpg on the highway.

As you can see we used the car's trip computer to do the math for us. We covered 3,197 miles and averaged 62 mph.

Not a bad pace or fuel economy considering the weather we drove through and our many stops for photography.

If you missed it, you can read about our road trip to South Dakota here and check out at huge photo gallery of our adventure here.
