Mercedes-AMG is bringing back its most potent V8 engines for the GLE 63 S Coupe and GLS 63, pairing them with a mild-hybrid system for enhanced performance and responsiveness. These updated models promise the signature AMG driving experience with sharper styling and advanced chassis technology.
Despite earlier speculation about the V8’s future, Mercedes-AMG is reaffirming its commitment to the engine configuration. The latest iterations of the GLE 63 S Coupe and GLS 63 are clear evidence, featuring comprehensive updates that enhance both performance and everyday usability.
Electrified V8 Muscle Delivers Serious Power
The core of these updated SUVs is a re-engineered twin-turbocharged 4.0-liter V8 engine. It now produces a formidable 603 horsepower and 627 pound-feet of torque. Enhancements include a new flat-plane crankshaft to reduce rotational mass, allowing the engine to rev more freely, and upgraded intakes and turbos designed to improve throttle response and overall efficiency.
A new 48-volt mild-hybrid system, featuring the ISG 2.0 Integrated Starter Generator, complements the V8. This system can deliver an additional 23 hp and 151 lb-ft of torque, providing an immediate boost in low-end torque and smoothing out low-speed driving. While not a full hybrid system, it contributes to a more immediate feel off the line.
These power upgrades translate to impressive acceleration figures. The GLE 63 S Coupe can achieve 0 to 60 mph in as little as 3.6 seconds, while the larger GLS 63 completes the sprint in 3.9 seconds. Both models have an electronically limited top speed of 174 mph.
Advanced Suspension for Dynamic Handling
Both the GLE and GLS 63 come standard with AMG Ride Control+ air suspension. This system is enhanced by AMG Active Ride Control, which uses real-time road scanning – up to 1,000 times per second – to actively counteract body roll. This technology aims to provide a more composed and dynamic driving experience, even during spirited maneuvers.
Further bolstering the performance credentials are a fully variable AMG Performance 4MATIC+ all-wheel-drive system and an electronically controlled rear locking differential. These components are designed to optimize traction and handling, ensuring that these powerful SUVs can effectively put their power down.
Subtle Styling Tweaks, Familiar Interior Design
Visually, the updated GLE 63 S Coupe and GLS 63 adopt a more restrained approach to styling updates. The fundamental proportions remain the same, but they now feature a new AMG-specific grille, revised LED lighting signatures, and larger front air intakes. At the rear, quad exhaust tips and a reshaped diffuser contribute to the performance aesthetic. The GLS specifically gains distinctive 10-spoke wheels.
Inside, the cabin retains its familiar layout with large displays and AMG-specific graphics. The new AMG Performance steering wheel incorporates drive-mode controls for easier access to performance settings. The integration of MB.OS software provides real-time performance data, including torque distribution, g-forces, and engine statistics, directly to the driver.
Mercedes-AMG also highlights the expanded MANUFAKTUR program, offering extensive personalization options. This includes a wide range of paint finishes and premium interior materials, such as Yacht Blue and Tartufo Brown leather combinations.
Pricing and Availability Remain Unconfirmed
The updated AMG GLE 63 S Coupe and GLS 63 represent a strong continuation of AMG’s focus on powerful V8 engines, now enhanced with mild-hybrid technology. While official pricing and specific availability details for the US market have not yet been announced, buyers should anticipate a significant investment for these high-performance SUVs.
