The 2021 Mercedes-AMG GLE 63 and 63 S are the direct descendants of the original ML 55. However, while the latter featured a 342 HP V8 engine, these newest iterations produce 563 HP (571 PS) and 603 HP (612 PS) respectively.
Their 4.0-liter V8 biturbo unit also works alongside with the EQ Boost starter-alternator, delivering an additional 22 HP (16 kW) to go with a 48-volt on-board electrical system. Other goodies include the TCT 9G transmission, all-wheel drive, adaptive damping and active roll stabilization.
Quit stalling, is it quicker than an X5 M?
The GLE 63 packs 563 HP (571 PS) and 750 Nm (553 lb-ft) of torque, while the S variant puts down 603 HP (612 PS) and 850 Nm (627 lb-ft), with the aid of the 9-speed automatic and 4MATIC+ all-wheel drive. In a straight line, the base 63 will hit 100 km/h (62 mph) in 4.0 seconds flat, whereas the S needs just 3.8 seconds.
These acceleration figures are near identical to those of the BMW X5 M and X5 M Competition, which pack more oomph at 592 HP (600 PS) and 617 HP (625 PS) respectively, with 750 Nm (553 lb-ft) of torque apiece, completing the sprint in 3.9 and 3.8 sec respectively.
As for top speed, the quickest GLE you can buy will max out at 280 km/h (174 mph), slightly slower than the X5 M when fitted with the M Driver’s package (180 mph).
In terms of looks, the GLE 63 family gains an AMG-specific grille, imposing power domes in the hood, front splitter, side skirts, vehicle-color flared wheel arches and large AMG wheels (20-inches for the GLE 63 and 21-inches for the 63 S). At the back, there’s a new rear apron with AMG-specific details such as the silver shadow trim strip, but also the AMG exhaust and a roof edge spoiler.
Inside, you get AMG seats in nappa leather, AMG badges, ambient lighting as standard, a performance steering wheel with aluminum shift paddles, AMG-specific control panel for the center console, stainless steel sports pedals, door sill panels and black floor mats with AMG lettering. It’s worth noting that the steering wheel features a black nappa leather rim in the GLE 63 model and a nappa leather / Dinamica microfibre design in the S variant.
Other tech features include the latest MBUX infotainment system with dual screens (and specific AMG displays), AMG-specific Dynamic Select drive programs, the optional Energizing package Plus, Warmth Comfort package, Air-Balance package and the Driving Assistance package.
