- The new M177 EVO V8 engine generates a combined output of 603 horsepower and 850 Nm of torque.
- An integrated 48-volt mild-hybrid system provides an additional boost of 23 horsepower and 205 Nm of torque.
- The GLE 63 S completes the 0-96 km/h sprint in 3.6 seconds, while the GLS 63 achieves the same in 3.9 seconds.
- Adaptive Ride Control+ suspension technology adjusts vehicle height and damping based on specific driving modes.
The M177 EVO Engine Provides Hybrid Assistance
At the heart of these refreshed SUVs lies the sophisticated 4.0-liter twin-turbocharged M177 EVO unit. Initially introduced in the updated S-Class, this powerhouse delivers 603 horsepower and 850 Nm of torque, ensuring relentless acceleration. {{WP_IMAGE_1}}
Complementing this internal combustion engine is a 48-volt mild-hybrid system featuring an integrated starter-generator. This electrification layer provides a tactical boost of 23 horsepower and 205 Nm of torque, smoothing out power delivery and supporting the vehicle’s dynamic capabilities. 
The integration of mild-hybrid technology significantly enhances the responsiveness of the powertrain during rapid acceleration.
All power is managed through an AMG Speedshift TCT nine-speed automatic transmission and a 4Matic+ all-wheel-drive system. This intelligent setup allows for variable torque distribution, ensuring optimal traction across varying road surfaces and driving styles.
Advanced Technologies Improve Driving Dynamics
Performance figures for these SUVs are equally impressive given their scale. The GLE 63 S is capable of hitting 96 km/h in just 3.6 seconds, whereas the larger GLS 63 completes the same task in 3.9 seconds. Both models reach a top speed electronically capped at 280 km/h. 
To manage this velocity, Mercedes-AMG has equipped both vehicles with the Ride Control+ air suspension system. The adaptive damping allows the vehicle to lower itself in Sport and Comfort modes, while the Trail mode increases ground clearance by 2.2 inches for off-road excursions. 
Active Ride Control technology minimizes body roll to keep the massive SUVs planted during aggressive cornering.
Additional chassis refinements include an electronically controlled locking rear differential, which improves cornering precision. Visually, the GLE features a darkened front grille and sharper air intakes, while the GLS maintains a classic chrome finish and offers optional 23-inch alloy wheels. 
The interior reflects a high degree of luxury with a new AMG Performance steering wheel available in leather or microfiber. Carbon fiber trim and customizable upholstery options further distinguish the cabin, emphasizing the brand’s commitment to bespoke quality.
