The 2022 Mercedes-Benz AMG GLC43 4matic with its 3.0L 6-cyl engine is rated at 21 MPG combined. To be clear no one buys an AMG GLC43 because it saves fuel. The priority is performance, for buyers who want a practical compact SUV with AMG’s signature theatrics and power. The fuel bill is a secondary concern, a price to be paid for the experience.

City and highway performance

The EPA estimates 18 MPG for city driving and 25 MPG on the highway. These highway figures are achievable with a light foot. When you tap into the 3.0L twin-turbo V6’s 385 horsepower and 384 lb-ft of torque, which you will, those numbers will drop. In the city, stop-and-go traffic will also affect efficiency. The 9-speed automatic transmission is generally smooth and responsive, but it can sometimes hesitate in lower gears, further affecting efficiency around town.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz AMG GLC43 4matic at $2,750. This is based on driving 15,000 miles per year and using the national average fuel price. This is just an estimate. More aggressive driving, higher fuel prices or driving more than 15,000 miles annually will increase your actual fuel costs.

Real-world expectations

Real-world MPG is typically slightly below official EPA estimates, especially with a performance vehicle so easily coaxed into spirited driving. Expect something in the 16-19 MPG range in mixed city/highway driving if you enjoy the AMG GLC43’s performance capabilities. Drivers who are conservative and spend more time on the highway, driving at constant speed, might see numbers closer to the EPA’s 25 MPG highway rating.

How it compares

The AMG GLC43’s fuel economy is in the middle of its competitors. The Audi SQ5, with its 3.0L turbocharged V6, gets a similar 21 MPG combined. The BMW X3 M40i, with a turbocharged inline-six, also gets around 21 MPG combined. A Porsche Macan S, another performance SUV, is rated at 19 MPG combined. The less sporty Mercedes-Benz GLC300 manages a more palatable 25 MPG combined, but it lacks the AMG’s visceral punch. For those willing to consider slightly larger SUVs, the Range Rover Sport with its mild-hybrid inline-six can achieve around 21 MPG combined as well, offering a different kind of luxury and performance. If fuel efficiency is a high priority, buyers will be comparing these vehicles alongside AMG MPG across all years.

Tips to maximize efficiency

Take advantage of the AMG GLC43’s drive modes. “Comfort” mode prioritizes fuel efficiency by adjusting the throttle response, transmission shift points, and suspension settings. While it won’t completely transform the car, it can make a small difference in everyday driving.

Avoid aggressive acceleration and hard braking. The more you demand from the engine, the more fuel it consumes. Smooth, predictable driving will not only improve MPG but also enhance the overall driving experience. Coasting to red lights helps.

Ensure your tires are properly inflated. Properly inflated tires reduce rolling resistance, which directly impacts fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the door jamb sticker.

Minimize unnecessary weight. Carrying around unnecessary items in your car adds weight, forcing the engine to work harder and consume more fuel. Clean out your trunk and remove any items you don’t need on a regular basis.

Plan your routes strategically. Avoid stop-and-go traffic as much as possible. Choose routes with fewer lights and less congestion. Using navigation apps like Google Maps or Waze can help you find the most efficient route to your destination.
