The 2020 Mercedes-Benz AMG GLC63 4matic Plus Coupe gets 18 MPG combined. This isn’t a fuel-efficient car pretending to be a performance machine. It’s a hand-built AMG with a powerful engine, sculpted into a coupe-like crossover. Performance is the priority, offering quick acceleration and great cornering. This vehicle appeals to drivers who value exclusivity, and for them, the fuel cost is part of owning a very exclusive car.

City and highway performance

The EPA estimates 16 MPG in the city and 22 MPG on the highway. Stop-and-go driving will use more fuel, as the 4.0L V8 works harder to accelerate. On the open road, maintaining consistent speeds and using a light touch on the accelerator makes achieving 22 MPG possible, especially by using the 9-speed automatic’s higher gears. Resisting the urge to enjoy the twin-turbo V8 is difficult, so expect slightly lower numbers than the EPA estimates with enthusiastic driving.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mercedes-Benz AMG GLC63 4matic Plus Coupe at $3,200. This is based on driving 15,000 miles per year with a combination of city and highway driving, and uses the national average fuel price at the time of calculation. Your actual fuel costs can change based on your driving, fuel type, and local fuel prices. Consider this number when comparing it to other models.

Real-world expectations

The EPA numbers are a starting point, but driving habits and conditions matter. Expect fuel economy to decrease if you often use the AMG’s full performance. Short trips, cold weather, and aggressive driving all hurt fuel efficiency. Longer highway trips at steady speeds might produce better results, but don’t expect big gains. A buyer of this AMG probably isn’t focused on fuel efficiency, and that’s fine.

How it compares

Compared to its rivals, the AMG GLC63 Coupe’s fuel economy is normal for its performance class. The BMW X4 M Competition, with its inline-6 turbo engine, gets around 16 MPG city and 22 MPG highway, practically the same. The Porsche Macan Turbo has slightly better combined fuel efficiency at 19 MPG, but the difference is small. These vehicles have different driving dynamics. Drivers who like badge prestige and handcrafted engines might accept using more gas for the AMG experience. You can compare all Mercedes Benz fuel economy data and see if another model might be a better fit.

Tips to maximize efficiency

Fuel efficiency might not be the priority for an AMG GLC63 Coupe owner, but here are a few tips. Avoid accelerating quickly and braking hard. Smooth inputs will save fuel, especially in the city.

Use the AMG’s drive mode selector. Comfort mode, being less exciting than Sport or Sport+, optimizes the engine and transmission for efficiency. An economy mode is the first step.

Check your tire pressure. Underinflated tires increase rolling resistance, which hurts fuel economy. Correct tire pressure improves efficiency and handling.

Remove extra weight from the vehicle. Extra cargo adds weight, which uses more fuel. Remove unneeded items from the trunk to minimize the load.

Use cruise control on the highway when you can. Maintaining a consistent speed can help save fuel during longer trips. Watch traffic and be ready to turn off cruise control. It also helps to browse AMG MPG across all years.
