May 2, 2013

2012 Mercedes-Benz SLS AMG Roadster

We've been testing this Mercedes SLS AMG Roadster since December. And we've now driven it about 8,000 miles. During the month of April we drove the supercar about 1,700 miles. The mileage included a few highway road trips, plenty of commuting and more than a few fun runs through the Santa Monica Mountains.

Running exclusively on its required 91-octane fuel the Mercedes is averaging 14.9 mpg, which is about a point shy of its EPA combined rating of 16 mpg.

Worst Fill MPG: 9.6
Best Fill MPG: 20.3
Average Lifetime MPG: 14.9
EPA MPG Rating (City/Highway Combined): 14/20/16
Best Range: 378.6 miles
Current Odometer: 22,902 miles
