20 MPG combined. That’s what you can expect if you’re considering a 2020 Mercedes-Benz AMG C63 Coupe. This isn’t a fuel-sipping commuter, and no one buys this car to save the planet or pinch pennies. It’s a ferocious, V8-powered performance machine draped in seductive coupe styling, and the fuel bill is simply the price to join that club.

City and highway performance

The official EPA figures break down to 17 MPG in the city and 26 MPG on the highway. That city number reflects stop-and-go driving where the 4.0L V8 constantly pulls nearly two tons of German engineering from a standstill. The highway figure is more palatable if you can resist the urge to exploit the readily available horsepower. The 9-speed automatic transmission undoubtedly helps on longer trips, keeping the engine in its sweet spot for both performance and efficiency. A heavy right foot will negate any gains.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,900 for the 2020 AMG C63 Coupe. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and factoring in the current national average fuel price for premium gasoline. Consider this number as a benchmark. Your actual fuel costs will depend on your driving habits, local fuel prices, and how much you enjoy the car’s performance. Expect to exceed this figure if you regularly visit the track or live in an area with consistently high fuel prices.

Real-world expectations

Forget about hitting the EPA numbers consistently if you plan to drive the C63 hard. This car begs to be driven hard, and the sound of that hand-built V8 burbling and screaming towards redline is addictive. More realistic expectations for combined MPG are likely in the mid-teens, especially if your daily commute involves heavy traffic. Highway driving can deliver close to the EPA estimate if you exercise restraint, but the temptation to downshift and pass is ever-present.

How it compares

The AMG C63’s fuel economy isn’t as good as some of its competitors, as you might expect. The BMW M4 Competition manages a slightly better 20 MPG city and 26 MPG highway, though the difference isn’t dramatic. The Audi RS5 Coupe, with its turbocharged V6, boasts a respectable 18 MPG city and 28 MPG highway. Even the Cadillac ATS-V, though discontinued, sometimes offers surprisingly competitive MPG figures with its 16 MPG city / 23 MPG highway rating given its size and performance. Fuel economy isn’t the primary concern for buyers of these cars, but the differences can add up over time. If less gas is a higher priority, consider comparing all Mercedes Benz fuel economy data or narrowing your scope to AMG MPG across all years.

Tips to maximize efficiency

Though this car isn’t designed for hypermiling, small changes can affect fuel consumption.

Avoid aggressive acceleration and hard braking, as these deplete fuel reserves quickly. Anticipate traffic flow and maintain a steady speed. Use cruise control on long highway stretches to minimize throttle input.

Select the “Comfort” driving mode when you don’t need all the performance the C63 offers. This mode softens throttle response and allows the transmission to upshift earlier, keeping the engine in a more efficient operating range. This car has multiple personalities, and choosing the right one can make a small but noticeable difference in fuel economy.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which negatively impacts fuel efficiency. Check your tire pressures regularly, especially during seasonal temperature changes.

Minimize idling time. Modern engines are more efficient when turned off than when idling for extended periods. If you anticipate being stopped for more than a minute, consider turning off the engine.

Regular maintenance is critical for optimal fuel economy. Ensure your engine air filter is clean, and follow the manufacturer’s recommended service schedule. A well-maintained engine operates more efficiently, meaning better fuel consumption.
