What type of fuel economy does the Mercedes AMG G 63 have, and how does it compare to other SUVs in its class?

The Mercedes-AMG G 63 is not known for its fuel efficiency, but given its size and performance capabilities, this is to be expected. It has an EPA-estimated fuel economy of 13 mpg in the city and 15 mpg on the highway. However, the G 63 is designed for performance rather than fuel economy, and its owners are likely more concerned with the driving experience than the gas mileage.
