Mercedes-AMG Unveils Updated GLE 63 S and GLS 63 with Enhanced V8 and Mild-Hybrid Tech
Mercedes-AMG has revealed comprehensively updated GLE 63 S and GLS 63 SUVs, featuring a heavily revised 4.0-liter V8 biturbo engine with mild-hybrid assistance for improved performance and efficiency.
- 612 PS + 23 PS (ISG)
- 850 Nm + 205 Nm (ISG)
- 280 km/h (electronically limited)
What Happened
The heart of both models is the extensively reworked AMG M177 EVO 4.0-liter V8 biturbo engine, producing 450 kW (612 PS) and 850 Nm of torque. A new flat-plane crankshaft, modified camshafts, optimized injection, and advanced exhaust aftertreatment help the engine comply with global emissions standards while preserving its performance character. An integrated starter-generator (ISG) 2.0 adds 17 kW (23 PS) and 205 Nm, supporting low-end torque and energy recuperation.
Externally, both SUVs feature a redesigned front end with an AMG-specific grille, larger air intakes, and exclusive LED lighting. The AMG RIDE CONTROL+ air suspension with adaptive damping offers a wide range between comfort and sportiness, and the active AMG ACTIVE RIDE CONTROL anti-roll system minimizes body lean for precise handling. Inside, the latest MB.OS infotainment system and a new AMG Performance steering wheel with dedicated controls highlight the performance-oriented cockpit.
