13 MPG combined is not a typo. That’s what you get with the 2016 Mercedes-Benz AMG G63, a machine that defies logic and embraces excess. This isn’t a vehicle for the fuel-conscious; it’s for those who prioritize presence, performance, and a commanding view of the world, regardless of the cost at the pump. The G63 buyer isn’t cross-shopping hybrids. They’re buying an icon, a statement, and they’re acutely aware, and likely unconcerned, about its prodigious thirst.

City and highway performance

The split between city and highway mileage is surprisingly narrow: 12 MPG in the city and 14 MPG on the highway. This reflects the G63’s aerodynamic profile, which is like a brick wall; acceleration rates, traffic, and road surfaces barely affect the consumption. The 5.5L twin-turbo V8 requires substantial fuel to overcome its own mass and wind resistance at any speed. Expect short trips around town or even extended cruising to result in near-identical fuel consumption.

Annual fuel cost

The EPA estimates an annual fuel cost of $4,450 for the 2016 AMG G63. This calculation is based on driving 15,000 miles per year and using national average fuel prices at the time of testing. For drivers exceeding that mileage, or those residing in areas with higher fuel costs, the annual expenditure will quickly escalate. This cost is a direct consequence of the G63’s performance-oriented engine and heavy curb weight, and it’s a factor every owner should contemplate.

Real-world expectations

Forget the EPA numbers. Real-world mileage is almost always worse. Aggressive driving, stop-and-go traffic, and the sheer temptation to unleash the V8’s power reduce MPGs even further. It’s entirely possible many owners may find themselves with single-digit MPG figures if they spend most of their time in stop and go traffic, or at “spirited” cruising speeds. The G63’s weight, all-wheel drive system, and aggressive tuning work against fuel efficiency. If you are in the market for the 2016 Mercedes-Benz AMG G63, you will quickly get used to visiting the fuel station more frequently.

How it compares

Comparing the G63 to other vehicles in terms of fuel economy seems almost absurd, but it’s worth noting the stark differences. A 2016 Range Rover Supercharged, another performance-oriented SUV, manages a combined 16 MPG. A Porsche Cayenne Turbo of the same vintage pulls down 17 MPG combined. Even a large body on frame SUV like the mechanically similar 2016 Mercedes-Benz GL550 reaches 17 MPG combined. The G63 buyer is not interested in these vehicles. They want the style and statement that can only be found in the G63. The all Mercedes Benz fuel economy data showcases just how much of an outlier the G63 is. For those interested in AMG MPG across all years, the G63’s relative thirst remains consistent across generations.

Tips to maximize efficiency

While the 2016 AMG G63 is never going to be a paragon of fuel efficiency, there are a few strategies to slightly improve its consumption. Gentle acceleration and braking are key. The twin-turbo V8 responds instantly to throttle inputs, so avoid excessive pedal pressure unless you truly intend to unleash its full potential. Plan your drives deliberately and use cruise control whenever possible to help with maintaining a consistent speed.

Tire pressure plays an important role, especially in a heavy vehicle like the G63. Ensure your tires are inflated to the recommended pressure specified on the door placard. Under-inflated tires increase rolling resistance, leading to decreased fuel economy. Monitor your tire pressure regularly and adjust based on ambient temperature.

Minimize unnecessary weight in the vehicle. The G63 is already a heavy beast, so avoid carrying around items you don’t need. Every extra pound contributes to reduced fuel efficiency. Regularly declutter your vehicle to remove any unnecessary items.

Consider your drive mode settings. While the G63 doesn’t offer a dedicated fuel-saving mode, selecting the most efficient engine and drivetrain mode can make a marginal difference. Experiment with different settings and observe their impact on fuel consumption. The “Comfort” setting typically provides slightly better efficiency than the “Sport” or “Sport+” modes.
