17 MPG combined. No one spending a lot of money on a hand-built, twin-turbocharged AMG GT 63 4MATIC+ considers fuel efficiency their primary concern. This is a sedan (or coupe), a four-door designed for blitzing Autobahns and leaving a lasting impression, not squeezing every last mile from a gallon of premium.

City and highway performance

The EPA estimates are 15 MPG in the city and 20 MPG on the highway. These figures reflect the reality of a 4.0L V8 producing 630 horsepower. City driving, with constant stop-and-go, punishes the fuel tank. It is possible to achieve the highway number, but it requires restraint, which is hard for drivers who like to use the engine’s immense power reserve, which sends fuel economy toward the lower end.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2019 AMG GT 63 4MATIC+ at $3,400. This is based on driving 15,000 miles per year, using national average fuel prices (for premium gasoline, of course). This figure provides a benchmark but understand that spirited driving inflates that number. Commuting in heavy traffic, frequent short trips (where the engine doesn’t reach optimal operating temperature), and a heavy right foot contribute to a steeper fuel bill. Consider this in your budget alongside insurance, maintenance, and repairs.

Real-world expectations

Expect worse fuel economy than the EPA numbers, especially if you routinely exploit the car’s performance. You might achieve high teens on long road trips with careful throttle control. Around town, single digits are plausible if you enjoy the exhaust and the acceleration. The AMG GT 63’s thirsty engine isn’t a secret, it’s a deliberate choice. Buyers aren’t seeking economy; they want thrills and are willing to pay the price at the pump.

How it compares

The AMG GT 63 4MATIC+’s fuel economy is similar to its rivals. The Porsche Panamera Turbo S E-Hybrid manages a combined 20 MPG in hybrid mode. The BMW M8 Gran Coupe achieves 17 MPG combined, matching the AMG. An Audi RS7 posts 18 MPG combined. These sedans represent the best engineering, but efficiency is less important. Consumers who want all Mercedes Benz fuel economy data should explore other options, but the AMG GT 63 4MATIC+ driver probably won’t cross-shop with hybrids. Performance is the priority and they accept the trade-offs. Want more information on AMG MPG across all years? Explore our data to see how others compare.

Tips to maximize efficiency

A few strategies can help squeeze a few extra miles from each gallon. Use the “Comfort” driving mode for everyday driving. It recalibrates the throttle and transmission, which can improve fuel economy.

Avoid aggressive acceleration and braking. The AMG GT 63 4MATIC+ responds dramatically to throttle inputs. Gentle acceleration and anticipating traffic flow can minimize fuel consumption in the city.

Ensure your tires are inflated to the proper level. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure and inflate as needed.

Reduce aerodynamic drag by removing any cargo from the roof rack and avoid driving at high speed for long periods. The higher the speed, the greater the impact of drag on fuel efficiency.

Consider shorter trips in a more fuel-efficient vehicle to save gas and money. While the AMG GT 63 4MATIC+ is fun, it’s not always the most practical choice for errands.
