Fifteen MPG combined is a sobering figure, especially in an era of hybrid and electric SUVs. But that’s the official EPA rating for the 2019 Mercedes-Benz AMG GLE63 S Coupe with its thundering 5.5L V8. This isn’t about fuel efficiency; it’s about breathtaking performance with a dash of practicality. The buyers aren’t looking for the greenest choice. They’re seeking a statement, a visceral driving experience, and the undeniable presence that only a hand-built AMG can deliver. The trade-off for that intoxicating blend of power and style? Frequent visits to the gas station.

City and highway performance

The EPA estimates of 14 MPG in the city and 18 MPG on the highway reveal feeding a high-performance, large-displacement engine is expensive. Stop-and-go city driving puts immense strain on fuel consumption due to the vehicle’s hefty curb weight and the engine’s readily accessible power. Expect the turbos to be spooled and the fuel injectors working overtime. Highway driving offers some respite, allowing the engine to settle into a more efficient cruise, but even then, enthusiastic use of the accelerator will plummet those numbers quickly. Consider the quoted figures merely the starting point with the understanding that your individual experience will likely vary, and likely skew lower.

Annual fuel cost

The EPA estimates that owning a 2019 Mercedes-Benz AMG GLE63 S Coupe will cost $3,850 per year in fuel. This figure is based on driving 15,000 miles annually, using a blend of city and highway driving conditions, and relying on the national average fuel prices for premium gasoline. Keep in mind that premium fuel is required for optimal performance and longevity, adding to the running costs. Fluctuations in gas prices could significantly impact this estimate; however, considering its target market, the annual fuel cost is likely a secondary consideration.

Real-world expectations

While the EPA provides a baseline, real-world fuel economy of the AMG GLE 63 S Coupe will depend heavily on driving style. A lead foot will decimate those numbers, potentially dropping into the single digits during spirited driving sessions. Conversely, a conscious effort to drive conservatively on the highway could yield figures marginally higher than the EPA’s 18 MPG. But let’s be honest: few buy an AMG to hypermile. And the nature of this vehicle’s typical use, which often includes short trips and weekend excursions rather than long commutes, tends to exacerbate fuel consumption. Drivers who frequently indulge in the engine’s power are likely to experience far lower MPG figures than advertised.

How it compares

The AMG GLE63 S Coupe exists in a niche market, competing with other high-performance SUVs and coupes that prioritize performance over efficiency. The Porsche Cayenne Turbo Coupe, with its 4.0L V8, manages around 17 MPG combined, slightly better but still not exactly economical. The BMW X6 M, sporting a 4.4L twin-turbo V8, also hovers around the 16 MPG combined mark. Even the Range Rover Sport SVR, with its supercharged V8, lands in the neighborhood of 15 MPG. The AMG MPG across all years might not impress the everyday driver, but it is on par with competitors. These comparisons matter to the buyer contemplating a purchase in this performance segment. They acknowledge the inherent compromise but want assurances that they are not incurring an unreasonable penalty relative to alternatives that deliver a similar experience.

Tips to maximize efficiency

Resist the urge to unleash the engine’s full potential at every opportunity. The AMG GLE63 S Coupe begs to be driven hard, but doing so will drastically reduce fuel economy. Gentle acceleration and maintaining consistent speeds can significantly improve your average MPG. The thrill is still there, waiting for the right moment.

Use the car’s driving modes strategically. Select the “Comfort” mode for everyday commuting and highway cruising. This mode dampens the throttle response and optimizes the transmission for efficiency. Save the “Sport” and “Sport+” modes for when you truly want to experience the engine’s capabilities, knowing that fuel economy will suffer.

Ensure that the tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check the tire pressure regularly and adhere to the manufacturer’s recommended inflation levels, which can typically be found on a sticker located on the driver’s side doorjamb.

Reduce unnecessary weight. Carrying around extra cargo increases the vehicle’s overall weight, which negatively impacts fuel economy. Remove any non-essential items from the vehicle to minimize the burden on the engine. This is a high roller’s car, not a pickup truck.

Consider a more fuel-efficient vehicle for daily commuting or long trips. The AMG GLE63 S Coupe is fantastic, but for those who need a more fuel-efficient vehicle, you will find all Mercedes Benz fuel economy data available here. Using the AMG primarily for its intended purpose—spirited driving and special occasions—and reserving a more practical vehicle for everyday use can mitigate the impact of its inherent fuel consumption.
