Large and In-Charge Luxury Ride


Not quite as big as a Chevy Suburban, but sexier and lots more powerful, the 2021 Mercedes-Benz AMG GLS 63 4MATIC is a very high performance, full size SUV capable of accommodating seven (or six with optional second row captain’s chairs). It delivers a Mercedes S-Class level of interior luxury, rapid acceleration along with a plethora of state of the art technological features and equipment.

The gurus of performance tuning at Mercedes AMG have executed their magic on this full size GLS –Class SUV in the creation of the 2021 GLS 63, which draws its rapid transit motive force from a 4.0-liter, bi-turbo V-8, supported by an available semi-autonomous driving mode, along with a 48-volt hybrid system that helps to boost its performance.

Another nice touch is the Energizing package that includes an in-cabin fragrance diffuser and the Acoustic Comfort package, which adds more cabin insulation resulting in a quieter interior. also offers There is also a host of stand alone optional features offered by Mercedes-AMG including the awesome 23-inch multi-spoke forged wheels that are stunning nestled within the GLS63’s athletic wheel wells.

Despite its massive form, the 2021 GLS 63 AMG is without a doubt, the most attractive SUV in the Mercedes-Benz lineup.

In profile, the front and rear overhangs are short and the greenhouse is blacked out from the “B”-pillar to the rear sail panel.

First off, a vehicle this big shouldn’t be able to accelerate and maneuver with the agility and athleticism exhibited by the AMG GLS 63 4MATIC.
