21 MPG combined may seem like an average number, but for the 2020 Mercedes-Benz AMG GT 53 4matic Plus, it starts to make sense. This isn’t a practical sedan; it’s a performance four-door coupe with attractive styling, powered by a turbocharged engine with electric motor, for drivers who want fun without sacrificing all practicality.

City and highway performance

The AMG GT 53 gets its 19 MPG city and 24 MPG highway ratings through several features. Its 3.0L inline-six engine uses direct injection and turbocharging for better gas mileage. The 48-volt mild-hybrid system gives an electric boost during acceleration, reducing how hard the engine works and lowering fuel consumption. The nine-speed automatic transmission helps keep the engine at the right RPMs, which helps gas mileage on the highway. The “AMG” badge means performance, and Mercedes engineers have worked to balance power and efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mercedes-Benz AMG GT 53 4matic Plus at $2,750. This is based on driving 15,000 miles per year, using the national average fuel price for premium gasoline, the recommended fuel for this engine. It’s a significant cost compared to more fuel-efficient cars, but buyers of this car are likely willing to pay for the performance and prestige it offers.

Real-world expectations

Owners who often drive the AMG GT 53 hard will probably see fuel economy below the EPA estimates. Fast acceleration and high-speed driving will use more gas. But drivers who focus on smooth, efficient driving might get numbers close to, or even slightly above, the EPA’s claims. Driving style, traffic, and maintenance all affect real-world fuel economy. The 4MATIC all-wheel-drive system improves traction and performance and also slightly increases fuel consumption compared to a rear-wheel-drive car.

How it compares

The AMG GT 53’s fuel economy is similar to its competition. The BMW M850i Gran Coupe, a direct rival, gets about 20 MPG combined with a V8 engine. The Porsche Panamera 4S gets slightly better fuel economy at 21 MPG combined, but it drives differently. Even checking AMG MPG across all years, the 53 sits almost mid-pack. Buyers comparing these cars will likely value performance, luxury, and brand more than a few MPG. The marginal differences, however, may be a deciding factor for some. For a broader perspective, consider viewing all Mercedes Benz fuel economy data.

Tips to maximize efficiency

Select the right drive mode. The AMG GT 53 has driving modes like Comfort and Eco that set the powertrain for fuel efficiency. These modes soften the throttle, change shift points, and might reduce the electric boost, all helping to lower fuel consumption. Save the Sport and Sport+ modes for when you want full performance.

Keep your tires properly inflated. Keeping your tires inflated to the recommended pressure lowers rolling resistance, which improves fuel economy. Check your tire pressure often, especially when the temperature changes.

Anticipate traffic and drive smoothly so you don’t waste fuel. By anticipating traffic and driving smoothly, you can lower wasted energy. Keep a safe distance and avoid sudden moves.

Don’t idle for too long. Idling uses fuel without going anywhere. If you’ll be stopped for a while, like in a parking lot, turn off the engine.

Follow the maintenance schedule. A well-maintained engine is more efficient. Regular maintenance, including oil changes, air filter replacements, and spark plug replacements, keeps your AMG GT 53 working efficiently.
