2005 Mercedes-Benz CL65 AMG: Fuel Economy Update for March

April 7, 2014

2005 Mercedes-Benz CL65 AMG

Even though our 2005 Mercedes-Benz CL65 AMG has been in the garage for a few months now, it's new to much of the staff. As such, we are still having fun putting the bi-turbo V12 through its paces. So much so that in March, the CL65 fell just below the EPA combined driving estimate at 12.9 mpg. The overall fuel economy also dropped, to 14.1 mpg.

Lending the CL65 to Features Editor Mike Magrath and Photo Editor Kurt Niebuhr for a few days yielded an impressively low 9.5 mpg. That's second only to the current record of 6.5 mpg achieved after the Merc was dyno-tested in February. But that wasn't real driving, so it doesn't count.

Worst Fill MPG: 9.5 (6.5 in dyno-testing) 
Best Fill MPG: 19.6 
Average Lifetime MPG: 14.1 
EPA MPG Rating: 13 combined (11 city, 18 highway) 
Best Range: 408.7 
Current Odometer: 61,753
