Introduction: The Beast on Fuel
Let’s talk about something honest—the Mercedes-AMG G63. It’s not just a car; it’s a statement. A symphony of engineering wrapped in matte black panels and screaming V8 power. But if you’re thinking about buying one, you’ve probably asked yourself: “How much does it actually cost me at the pump?” That’s where Mercedes Amg G63 MPG comes into play.
This isn’t your average crossover or even a typical luxury SUV. The G63 is built like a tank—literally. Think of it as a modern-day W123 estate with rocket engines bolted underneath. It’s capable of rock crawling, towing 7,000+ pounds, and hitting 60 mph in under 4 seconds. Yet, behind all that muscle lies a thirsty engine that guzzles premium gasoline like it’s going out of style. So yes, the G63 gets poor gas mileage. But how bad is it? And more importantly—can you do anything about it?
In this deep dive, we’ll break down everything you need to know about the Mercedes Amg G63 MPG, from official EPA estimates to real-world owner reports, driving techniques that save fuel, and why this vehicle still makes sense despite its hunger for gas.
What Is the Official MPG Rating for the Mercedes-AMG G63?
The EPA fuel economy ratings for the 2024 Mercedes-AMG G63 paint a clear picture: 14 mpg city / 16 mpg highway / 15 mpg combined. These numbers are solid for a high-performance off-roader, but they’re far below what you’d get from a compact sedan like the Honda Civic or even a luxury hybrid like the Lexus RX 450h.

Why Are the Numbers So Low?
Several factors contribute to the G63’s modest MPG:
- Powertrain: The hand-built 4.0-liter twin-turbo V8 produces 577 horsepower and 627 lb-ft of torque. More power means more fuel burn—especially when you’re using it.
- <Curb Weight: At 5,646 lbs (base model), the G63 weighs nearly as much as two minivans. Every mile requires energy to move that mass.
- Aerodynamics: The boxy shape creates significant wind resistance. Unlike sleek coupes or wagons, the G63 wasn’t designed for aerodynamics—it was designed for durability and traction.
- Towing & Off-Road Prep: Features like locking differentials, reinforced axles, and heavy-duty suspension add unsprung weight and rolling resistance.
Still, these figures are actually better than previous generations. The last-gen G63 (pre-2020) struggled to crack 12 mpg combined—so Mercedes made real improvements under the hood.
Real-World vs. EPA Estimates
Don’t expect to hit 16 mpg on the highway every time. Most owners report getting between 12–15 mpg combined depending on driving conditions. Aggressive acceleration, frequent towing, mountain climbs, or city stop-and-go traffic will drop those numbers quickly. However, steady cruising on flat highways can push closer to 18 mpg—if you’re lucky and light-footed.
How Does the G63 Compare to Other Luxury SUVs?
If you’re comparing the Mercedes Amg G63 MPG against rivals, prepare for some eye-opening contrasts.
vs. Range Rover Sport SV
The Range Rover Sport SV also boasts a supercharged V8 (523 hp), but it achieves 15/21/17 mpg—slightly better thanks to lighter construction and more refined transmission tuning.
vs. Lamborghini Urus
Now that’s a beast! The Urus hits 13/18/15 mpg with a twin-turbo V8 tuned for track performance. Both consume fuel heavily, but the Urus edges ahead slightly in efficiency due to active aerodynamics and adaptive damping.
vs. Porsche Cayenne Turbo GT
The Cayenne Turbo GT manages 12/18/14 mpg. Again, similar territory—but Porsche’s focus on handling precision sometimes comes at the cost of outright fuel economy.
Bottom line? If you prioritize efficiency, none of these ultra-luxury SUVs are great choices. But if you want uncompromising performance and capability, the G63 stands apart—even if it drinks gas like a marathon runner.

Tips to Improve Your Mercedes Amg G63 MPG
You can’t redesign the G63 overnight, but there are practical ways to squeeze more miles per gallon without losing fun. Here’s how:
1. Drive Smarter, Not Harder
Aggressive throttle inputs spike fuel consumption. Instead:
- Avoid rapid acceleration from stops.
- Maintain steady speeds on highways using cruise control.
- Brake early and coast whenever possible—especially downhill.
Driving gently can improve your average MPG by 10–15%.
2. Use Eco Mode Wisely
The G63 has multiple drive modes—Sport+, Sport, Comfort, and Eco. While “Eco” reduces throttle response and shifts gears earlier, it won’t magically double your range. Still, it’s worth activating during daily commutes or long highway stretches.
3. Keep Up With Maintenance
Dirty air filters, underinflated tires, or clogged fuel injectors hurt efficiency. Follow Mercedes’ recommended service schedule:
- Replace spark plugs every 30,000–60,000 miles.
- Check tire pressure monthly (aim for 35 psi front/rear).
- Use only premium-grade fuel (91 octane or higher).
4. Reduce Unnecessary Load
Extra weight = more fuel burn. Remove roof racks when unused, ditch cargo carriers, and avoid carrying full gas tanks unless necessary. Some owners report 1–2 mpg gains simply by unloading heavy items.
5. Plan Routes & Avoid Traffic
Gridlocked cities force constant braking and restarting—each stop wastes fuel. Use navigation apps to find smoother routes with fewer red lights or congestion.
6. Consider Synthetic Oil
Switching to a high-quality synthetic oil reduces internal engine friction, improving combustion efficiency. Many AMG owners see subtle MPG bumps after switching from conventional oil.
Is There a Hybrid or Electric Version Coming?
As of 2024, no. The G63 remains strictly internal combustion-powered. However, rumors swirl about an electric AMG EQS SUV or a plug-in hybrid G63 variant in development. Given Mercedes’ push toward EQ branding and sustainability goals, don’t be surprised if a more efficient G-Class arrives within the next 3–5 years.
Until then, owners must accept the trade-off: peak performance paired with premium fuel costs. On average, filling up a G63 costs $120–$150 per tank (depending on location and gas prices). Over 15,000 miles annually, that adds up fast—but so does the thrill of owning one of the rarest AMGs on the road.
Ownership Costs: Beyond Just Gas Bills
While Mercedes Amg G63 MPG grabs headlines, true ownership costs include insurance, maintenance, depreciation, and downtime. The G63 commands top-dollar insurance premiums due to its performance specs and repair complexity. Parts aren’t cheap—expect $2,000+ for a new set of tires or $800 for brake pads.
However, resale value remains surprisingly strong. Well-maintained examples often retain 60–70% of original MSRP after three years—a rarity among high-end performance vehicles.
So yes, it’s expensive to own. But for enthusiasts who value exclusivity, capability, and raw power, the emotional payoff often outweighs the financial sting.
Final Thoughts: Should You Buy One?
The Mercedes-AMG G63 isn’t for everyone—and neither is its Mercedes Amg G63 MPG. If you prioritize fuel efficiency or live in a city with steep emissions taxes, look elsewhere. But if you crave a machine that laughs at snowstorms, crushes asphalt, and turns heads wherever it goes… then the G63 delivers in spades.
Just remember: you’re paying for the experience, not the miles per gallon. Treat it gently, maintain it obsessively, and enjoy every roar of that V8. After all, life’s too short for boring commutes.
