2027 Mercedes AMG GLE63 S and GLS63 Revealed with 603 HP V8 Power
Table of Contents
The 2027 Mercedes AMG GLE63 S and Mercedes AMG GLS63 have officially arrived with an updated version of the brand’s iconic 4.0 litre twin turbo V8 engine. While many luxury carmakers are moving towards smaller engines, Mercedes AMG has decided to keep the V8 alive, giving enthusiasts another reason to celebrate.
The latest performance SUVs continue to combine luxury, practicality, and serious performance. They also receive chassis improvements, updated styling, and mild hybrid assistance without compromising the character of the V8.
2027 Mercedes AMG GLE63 S and GLS63 Engine
At the heart of both SUVs sits the updated M177 Evo 4.0 litre twin turbocharged V8 engine.
Engine Specifications
| Specification | Details |
|---|---|
| Engine | 4.0-litre Twin-Turbo V8 |
| Power | 603 hp |
| Torque | 627 lb-ft |
| Hybrid System | Integrated Starter Generator |
| Additional Boost | 23 hp and 151 lb-ft |
| Drivetrain | AMG Performance All-Wheel Drive |
The integrated starter generator mainly improves low speed response and smoother acceleration. It adds a small electric boost instead of functioning as a full hybrid system.
Mercedes AMG has retained the impressive 603 horsepower output while making the engine more efficient to meet stricter emission standards.
Flat Plane Crank V8 Returns with a Different Character
One of the biggest highlights is the adoption of a flat plane crankshaft.
This crankshaft design is more commonly found in exotic supercars and produces a sharper and more aggressive exhaust note compared to the previous cross plane V8.
Interestingly, Mercedes says the change is aimed more at improving emissions compliance than increasing high RPM performance.
Peak power now arrives between 5,500 rpm and 6,100 rpm, compared to 6,500 rpm in the previous version.
Performance Figures
Despite weighing over two tonnes, both SUVs remain exceptionally quick.
| Model | 0 to 60 mph |
|---|---|
| Mercedes-AMG GLE 63 S | 3.6 seconds |
| Mercedes-AMG GLS 63 | 3.9 seconds |
Mercedes AMG also claims a top speed of up to 174 mph for these performance SUVs.
Real world testing could reveal even quicker acceleration, as previous generation models often outperformed their official claims.
Chassis Upgrades Improve Handling
Mercedes AMG has also focused on improving driving dynamics.
Key chassis features include:
- Electronic locking rear differential
- AMG Ride Control Plus air suspension
- Adaptive dampers
- Active anti roll stabilization
- Multiple drive modes including Comfort, Sport, and Sport Plus
These upgrades help reduce body roll during spirited driving while maintaining excellent ride comfort for daily use.
For an SUV of this size, the handling package promises impressive control without sacrificing refinement.
Adjustable Air Suspension Adds Practicality
The air suspension system also offers adjustable ride height depending on driving conditions.
It can:
- Raise the vehicle by 0.8 inch for rough roads or light off road driving
- Lower the body by 0.4 inch in Sport modes
- Automatically reduce ride height at speeds above 75 mph in Comfort mode for improved stability
It is a useful feature that balances comfort and performance without requiring any manual adjustments.
Exterior Design Updates
The 2027 models receive a refreshed appearance while keeping the familiar AMG identity intact.
Exterior highlights include:
- Updated AMG front grille
- New alloy wheel designs
- Sportier front and rear styling
- Expanded Manufaktur personalization options
Customers can choose exclusive paint finishes and bespoke interior combinations to create a more personalized luxury SUV.
Interior Remains Luxurious
Inside, both SUVs continue to offer premium materials and advanced technology.
The available Manufaktur interior themes add a more exclusive touch, with combinations like Yacht Blue upholstery paired with Moonlight White Magno exterior paint standing out among the new options.
The cabins continue to prioritize luxury, comfort, and high quality craftsmanship while delivering AMG performance credentials.

However, considering the previous generation started above:
- Around $130,000 for the GLE63 S
