Mercedes-AMG GLS 63 and GLE 63 S Facelifts Revealed

Mercedes-AMG has officially unveiled the facelifted Mercedes-AMG GLS 63 and Mercedes-AMG GLE 63 S, introducing a powerful 4.0-litre twin-turbocharged V8 engine equipped with a 48V mild hybrid system. These luxury performance SUVs now feature a motorsport-inspired flat plane crankshaft, improved throttle response, and refined chassis dynamics, ensuring they remain among the fastest and most capable vehicles in the global SUV segment.

Engine and Performance Upgrades

The core of these updates is the refined M177 EVO V8 engine. By integrating a flat plane crankshaft, AMG engineers have successfully reduced rotational mass, allowing the engine to rev with greater freedom.

• 48V Mild Hybrid System: Provides an additional 23 hp for instant acceleration.
• Enhanced Components: Revised fuel injection, camshafts, and turbocharger housings.
• Rapid Acceleration: The GLE 63 S hits 100 kmph in 3.9 seconds, while the GLS 63 achieves it in 4.2 seconds.
• Top Speed: Both models reach an impressive 280 kmph.

Hardware and Driving Dynamics

To handle the immense power output of the V8, Mercedes-AMG has significantly upgraded the suspension and drivetrain hardware. The active ride control system now features improved tuning to minimize body roll during high-speed cornering. Furthermore, the front and rear driveshafts have been reinforced, and the GLS 63 now benefits from a rear axle locking differential for superior traction.

Advanced Exhaust and Handling

The driving experience is further amplified by an updated active exhaust system. This unit automatically adjusts its sound profile based on driving mode and throttle input, providing a subtle tone during daily commuting and an aggressive roar during spirited drives. These refinements demonstrate AMG's commitment to balancing raw power with daily usability.

Conclusion

The updated Mercedes-AMG GLS 63 and GLE 63 S represent a successful return to traditional V8 performance enhanced by clever mild hybrid efficiency. With significant mechanical revisions and handling improvements, these facelifts solidify their position as leaders in the ultra-luxury performance SUV market.
