2019 Mercedes-Benz AMG GLC43 4matic Coupe Fuel Economy: What to Expect

21 MPG combined from the 2019 Mercedes-Benz AMG GLC43 4matic Coupe requires some explanation. This isn’t just a typical SUV; it’s a sharply styled performance machine with a potent turbocharged V6 designed for driving enjoyment. Buyers of this vehicle often value performance and exclusivity more than excellent fuel mileage. They know the AMG badge has costs, including the price at the pump.

City and highway performance

The EPA estimates 19 MPG in the city and 24 MPG on the highway. The city figure reflects the engine’s demands in stop-and-go traffic, where the turbocharger constantly spools up and the nine-speed automatic transmission works hard. The highway number, while better, shows the GLC43’s aerodynamic compromises from its coupe design, which needs more power to maintain high speeds and slightly offsets the benefits of the tall ninth gear. Buyers should expect lower mileage if they drive aggressively and frequently the engine’s power. However, in normal highway cruising, drivers might see numbers higher than 24, depending on driving style and road conditions.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for the 2019 AMG GLC43 Coupe. This number is based on driving 15,000 miles per year, using national average fuel prices, and the vehicle’s city and highway MPG ratings. Actual costs may vary depending on driving habits, local fuel prices, and fuel type. While the number might seem high, consider that it’s a reasonable price for the performance and prestige offered by the AMG GLC43, especially compared to similar vehicles. This cost should not surprise those shopping in this category, as they are likely used to the higher operating costs of performance vehicles.

Real-world expectations

While the EPA provides a standard estimate, your real-world MPG will depend on factors like driving style, whether you mostly take short city trips or longer highway journeys, and regular maintenance, which includes tire pressure checks and air filter changes. Expect slightly lower numbers in colder weather, as engines are less efficient when cold, and winter tires often increase rolling resistance.

How it compares

The 2019 AMG GLC43’s fuel economy falls within the expected range for a performance-oriented SUV Coupe, compared to its rivals. The BMW X4 M40i, another direct competitor, achieves a similar 21 MPG combined. The Porsche Macan S, while offering a more focused driving experience, is rated slightly lower, around 19 MPG combined. Upgrading to the AMG GLC63 S version significantly decreases fuel economy, with early models closer to 16 MPG combined. For those seeking less gas without sacrificing luxury, the non-AMG GLC300 offers better fuel economy, rated at 24 MPG combined, but with reduced performance. Buyers should consider the trade-offs, as performance and fuel economy affect each other.

Tips to maximize efficiency

Be gentle on the accelerator. The AMG GLC43’s turbo V6 is responsive, but you don’t always need its full potential, especially in city driving. Accelerating gently and predicting traffic flow can significantly improve fuel economy.

When appropriate, use the ECO drive mode. While not ideal for fast driving, the ECO mode can improve fuel efficiency in everyday situations by adjusting throttle response and shift points and reducing fuel consumption.

Make sure your tires have the right amount of air. Maintaining the correct tire pressure for your AMG GLC43 optimizes rolling resistance, helping fuel economy and even tire wear. Check the sticker on your driver’s side doorjamb for the recommended pressure.

Reduce idling. Modern cars consume fuel even when stopped. Avoid idling longer than needed, especially in stop-and-go traffic or when waiting. Turning off the engine can save a measurable amount of fuel.

Keep up with regular maintenance. A well-maintained engine is an efficient engine. Following the recommended service schedule, including oil changes, air filter replacements, and spark plug replacements, can help maintain fuel economy and all Mercedes Benz fuel economy data.
