The 2025 Mercedes-AMG GLE 63 S stands at the crossroads of high-performance engineering and everyday SUV practicality. It blends a handcrafted V8 twin-turbo powertrain, AMG-tuned chassis, and the utility expected from a large SUV into a single package — appealing to those who demand both speed and space. In this review, I assess the GLE 63 S from multiple angles: exterior design and presence, interior comfort and usability, physical dimensions and packaging, powertrain and performance, driving dynamics, technology & safety, ownership costs, and finally competitive positioning.
1. Exterior Design & Visual Presence
The GLE 63 S projects a commanding presence on the road — something AMG vehicles have always done well. Key aspects:
- Muscular proportions, with a broad stance and aggressive detailing, communicate performance even before the engine starts.
- AMG-specific cues: distinctive front fascia, larger air intakes, quad exhaust outlets, prominent wheels and tires, and sporty trim make it visually distinct from standard GLE models.
- Overall design balances between luxury SUV sophistication and performance-SUV aggression — ensuring it fits both urban luxury environments and open-road driving.
In short: the 2025 GLE 63 S doesn’t hide its intentions — it shows them.
2. Physical Dimensions & Interior / Cargo Packaging
Here are the key size and packaging data for the 2025 GLE 63 S, affecting comfort, practicality and utility:
| Specification | Value |
|---|---|
| Overall Length | 195.0 in (approx. 4,953 mm) |
| Overall Width (without mirrors) | 79.4 in (~2,017 mm) |
| Overall Height | 70.2 in (~1,783 mm) |
| Wheelbase | 117.9 in (~2,995 mm) |
| Seating Capacity | 5 passengers (standard) |
| Cargo Volume (behind 2nd row) | 33.3 cu ft |
| Maximum Cargo Volume (seats folded) | up to 74.9 cu ft |
| Towing Capacity (braked) | 7,700 lbs (~3,500 kg) |
| Fuel Tank Capacity | 22.5 gallons (~85 L) |
| Curb Weight | ~5,567 lbs (varies by spec) |
Interpretation — What this Means in Practice
- The GLE 63 S occupies the “full-size luxury SUV” envelope — it offers abundant interior and cargo space, comfortable for five adults.
- Cargo capacity (33.3 cu ft rear + up to 74.9 cu ft folded) puts it among the most versatile performance SUVs in its class — practical for family trips, luggage, or even moderate hauling.
- The 7,700 lb towing capacity means it’s capable of towing substantial trailers — useful for owners who want a performance vehicle that can also work as a true SUV.
- Despite its heft, the long wheelbase contributes to stable highway behavior and interior ride comfort; but the curb weight reflects that engineering and luxury come at the cost of mass.
In summary: the GLE 63 S manages to combine performance SUV DNA with genuine practicality — rare in high-performance segments.
3. Interior, Comfort & Luxury Experience
Behind the aggressive exterior, the cabin of the GLE 63 S aims high in luxury, comfort, and technology. Highlights include:
- Premium materials and refined finish typical of AMG models — sport seats, leather, quality trim and attention to tactile feedback. According to recent reviews, the cabin continues to “sit at the top of the segment in quality, fit and finish.”
- Spaciousness: ample headroom and legroom in front and rear seats make long journeys comfortable even for taller passengers.
- Practical usability: seats fold to expand cargo, the SUV layout remains versatile — enabling a dual identity: a performance car and a family hauler.
- Comfort & convenience: usual AMG-luxury amenities — though exact trim varies by specification and optional packages.
Overall: the 2025 GLE 63 S does not sacrifice comfort or usability for performance — rather, it blends them.
4. Powertrain & Performance
At the mechanical core of the GLE 63 S lies its formidable drivetrain:
- Engine: 4.0-liter twin-turbo V8, handcrafted by AMG.
- Output: 603 horsepower and 627 lb-ft torque.
- Transmission: AMG SPEEDSHIFT 9-speed automatic with 4MATIC+ AWD as standard.
- Performance: 0–60 mph in ~3.7 seconds, marking it among the fastest SUVs globally.
- Towing capability and SUV versatility remain part of the package — a testament to AMG’s dual-purpose engineering philosophy.
What this powertrain delivers: immediate throttle response, strong acceleration, stable AWD traction, and a torque-rich driving character. The V8’s delivery is smooth but athletic, and the automatic transmission allows for both refined commuting and aggressive driving with minimal fuss.
5. Driving Dynamics & Comfort: Real-World Behavior
Analyzing how the GLE 63 S behaves on real roads — both mundane and demanding — reveals its strengths and compromises:
✅ Strengths
- Acceleration and highway merging are effortless thanks to the 603 hp V8; the 0–60 mph in 3.7 sec makes the SUV genuinely fast.
- All-wheel drive + adaptive suspension give the heavy SUV composure, even under spirited driving or in less-than-perfect road conditions.
- Ride quality vs performance balance: Despite the high performance, the adaptive suspension and chassis tuning allow smoothness over daily roads while retaining responsiveness when pushed.
- Versatility: From daily commuting and family duty to spirited driving on open roads, the GLE 63 S flexes across roles without feeling compromised.
⚠️ Trade-offs / Limitations
- The heavy mass makes nimble handling on twisty roads more challenging compared to lighter performance vehicles. Expect some body roll and delayed turn-in compared with sports SUVs or sedans.
- Fuel economy naturally suffers: EPA combined rating is about 16 mpg (14 city / 19 highway) under typical conditions.
- For daily drivers who prioritize maximum efficiency or minimal fuel cost, the GLE 63 S represents a significant running cost compared with more modest SUVs or hybrids.
In practice: GLE 63 S excels when the owner values performance, flexibility, and luxury over maximal efficiency — it remains one of the most compelling “do-it-all” performance SUVs.
6. Technology & Safety Features
As befitting a modern luxury-performance SUV, the 2025 GLE 63 S integrates a wide suite of tech and safety:
- Adaptive suspension system with active roll stabilization (on models equipped with AMG ACTIVE RIDE CONTROL+), ensuring stable body control during dynamic driving.
- Modern infotainment, comfort and convenience features comparable to its luxury SUV peers (though options vary by trim).
- Utility features: generous cargo space, towing capability, and a configuration that mixes performance character with real-world usefulness.
Though full detailed safety ratings (e.g. crash test scores) depend on region and trim, the structural design and passive/active safety systems align with expectations for a premium SUV.
7. Ownership Costs, Practical Considerations & Value
Owning a GLE 63 S brings benefits — and costs. Key considerations:
Costs and Economy
- Fuel consumption is modest for a performance SUV: combined ~16 mpg.
- Insurance, maintenance, and potential tire or brake wear costs may be higher relative to non-performance SUVs due to heavier loads and higher performance demands.
- Warranty coverage (typical of Mercedes-Benz) — but long-term value retention often depends on usage, maintenance and market demand for high-performance SUVs.
Value proposition
- For buyers wanting one car that handles family duties, long trips, towing, and yet delivers sports-car acceleration — GLE 63 S offers one of the best “all-around” packages in its segment.
- The combination of brand prestige (AMG badge), performance heritage, utility and luxury gives it strong appeal among those who value versatility without compromise.
8. Competitive Landscape: Where GLE 63 S Stands
The GLE 63 S competes with other high-performance luxury SUVs — each with its own trade-offs and strengths. In the 2025 landscape, key competitors might include performance-tuned SUVs from other German and premium brands (e.g. high-end variants of BMW X5 / X6, Audi RS-family SUVs, maybe high-performance trims from other luxury automakers).
What the GLE 63 S brings to the table compared with many rivals:
- Handcrafted AMG V8 heritage rather than purely turbocharged or hybrid setups.
- Balanced versatility: performance + towing + cargo + comfort — a more “do-everything” approach than some niche performance SUVs or sedans.
- Strong real-world usability: large cargo and passenger space, practical dimensions, and SUV utility without losing AMG character.
That said, rivals may outperform it in areas like lighter weight agility, fuel efficiency (especially hybrid or EV competitors), or lower ownership cost.
9. Summary — Pros, Cons, and Ideal Buyer Profile
