Mercedes-AMG has revealed the facelifted GLE 63 S and GLS 63 performance SUVs. Both models receive the new M177 EVO 4.0-litre twin-turbo V8 engine as part of their mid-cycle update. Although power figures remain unchanged, Mercedes-AMG claims the new engine delivers better efficiency, quicker throttle response, and improved drivability. The updates also introduce chassis refinements and enhanced performance technology.
New M177 EVO V8 Engine
The biggest highlight is the new M177 EVO twin-turbo V8 engine. It uses a motorsport-inspired flat-plane crankshaft that reduces rotating mass and improves engine response. In addition, Mercedes-AMG has revised the firing order, camshaft, fuel injection system, intake ports, exhaust ports, and turbocharger housing. Consequently, the engine revs more freely while delivering better fuel efficiency.
Performance & Mild-Hybrid Technology
The 4.0-litre twin-turbo V8 produces 612 HP on its own. Meanwhile, a 48V mild-hybrid starter-generator contributes an additional 23 HP during acceleration. The system also improves low-speed torque, supports energy recuperation, and enables smoother engine restarts. As a result, the GLE 63 S accelerates from 0 to 100 KM/H in just 3.9 seconds, while the GLS 63 completes the sprint in 4.2 seconds.
Chassis Upgrades & Driving Dynamics
Mercedes-AMG has introduced several mechanical improvements alongside the new engine. The updated active ride control system reduces body roll and improves handling. Moreover, engineers have strengthened the front and rear driveshafts to handle the increased load. The GLS 63 also benefits from a rear axle locking system, which further enhances traction during spirited driving.
Exterior & Functional Updates
The facelift focuses mainly on mechanical upgrades rather than major styling changes. However, Mercedes-AMG has revised the exhaust system with automatically adjustable flaps that deliver a more engaging soundtrack. In addition, both SUVs now feature a standard particulate filter to meet the latest global emission regulations without compromising performance.
Prices In India
Mercedes-Benz has not announced India prices for the facelifted AMG GLE 63 S and GLS 63. However, both performance SUVs are expected to arrive in India after their global launch. Based on current pricing trends, the GLE 63 S could cost around ₹2.30 crore, while the larger GLS 63 may start at approximately ₹3 crore (ex-showroom).
India Launch Expectations
Mercedes-Benz is expected to introduce the updated AMG SUVs in India after completing their international rollout. These models will continue to target buyers seeking high-performance luxury SUVs with everyday practicality. Once launched, they will compete with rivals such as the BMW XM, BMW X5 M Competition, Porsche Cayenne Turbo E-Hybrid, and Range Rover Sport SV.
Future AMG Strategy
The new M177 EVO engine marks a significant shift in Mercedes-AMG’s future strategy. Instead of relying on plug-in hybrid performance systems, the brand is returning to refined mild-hybrid V8 powertrains. Moreover, reports suggest the next AMG C 63 could also adopt this V8 engine, replacing its current plug-in hybrid setup.
Conclusion
The facelifted Mercedes-AMG GLE 63 S and GLS 63 combine proven V8 performance with improved efficiency and sharper response. Furthermore, the updated chassis, revised engine, and mild-hybrid technology make both SUVs even more capable. As Mercedes-AMG continues refining its iconic V8 formula, these flagship SUVs remain among the most exciting performance luxury vehicles in the segment.
