by New “charged” SUVs from Mercedes-AMG: GLE 63 S and GLS 63
Only three months after the presentation of the updated GLE, GLE Coupe, and the new GLS, Mercedes has introduced the “crazy” versions of the GLE 63 S and GLS 63 from the AMG division. Both models share common powertrains, combining power, performance, and luxury in the characteristic Mercedes-AMG style. Prices for the new models have not yet been announced.
New M177 EVO engine: power and efficiency
The heart of both SUVs is the new M177 EVO engine from Mercedes. This is a 4.0-liter twin-turbo V8 with a flat-plane crankshaft, which recently debuted in the updated S-Class and will be implemented in other updated AMG models. It produces the same 603 hp as the previous V8, but is more efficient and, thanks to the new crankshaft, provides better throttle response.
For the GLE 63 S (in SUV and Coupe versions) and the GLS 63, the maximum torque is 627 lb-ft (850 Nm) in the range from 2500 to 4500 rpm.
Working alongside the new engine is an integrated starter generator and a 48-volt mild hybrid system, which adds an additional 23 hp and 151 lb-ft (205 Nm) of torque. Both models use the latest nine-speed AMG Speedshift TCT transmission and 4Matic+ all-wheel drive with fully variable torque distribution.
Dynamics and handling
When you press the accelerator pedal, the GLE version can accelerate to 60 mph (96 km/h) in just 3.6 seconds and reach an electronically limited top speed of 174 mph (280 km/h). The larger GLS 63 reaches the same speed of 174 mph (280 km/h), but is slightly slower to 60 mph — in 3.9 seconds.
In addition to the powerful new engine, the latest AMG SUVs are equipped with Ride Control+ air suspension with adaptive damping and several modes. Among them is a Trail mode, where the ground clearance increases by 2.2 inches, making it ideal for off-roading, although it is unlikely that many GLE or GLS owners will ever leave well-paved roads. In the Sport, Sport+, and Comfort modes, the ground clearance is reduced by 0.4 inches relative to the standard position.
Working together with the air suspension is the AMG Active Ride Control system, which minimizes body movements. Fully variable torque distribution and an electronically controlled locking rear differential should also ensure good handling for the SUVs, despite their size.
Exterior changes and interior
As one might guess, visual changes have been made to both models, although they are not as noticeable as on some other AMG models. The GLE versions include a darkened front radiator grille and modified air intakes, while the GLS retains a more traditional chrome grille. Both models feature unique alloy wheels, available up to 22 inches for the GLE and 23 inches for the GLS, as well as twin exhaust tailpipes, which one would expect from an AMG model.
Changes have also been made to the interiors of both SUVs, including a new AMG Performance steering wheel, offered in leather, microfiber, or a combination of both materials. Unique upholstery options and a large number of carbon fiber inserts are also available.
These updated GLE 63 S and GLS 63 models demonstrate that Mercedes-AMG continues to refine its most powerful SUVs, with a focus on improving engine efficiency and driving dynamics. Despite the fact that the exterior changes may seem restrained, the technical updates, particularly the new engine and hybrid system, significantly enhance their characteristics. This makes them even more attractive for those seeking a combination of luxury, power, and modern technology in a large SUV.
