Testing of the next-generation high-performance Mercedes-AMG GLS 63 has been ongoing for more than 12 months, but the Germans have just now started peeling off the heavy camouflage on their prototypes, with this example giving us our clearest look yet. (Updated 5/5/2019)
The 2020 Mercedes-AMG GLS 63 is currently in the development phase and, based on these spy shots, it should be more aggressive-looking than ever.
Obviously, the AMG model will be more aggressive detailed than regular GLS, receiving a bespoke, six-corner ‘Panamericana’ grille featuring chrome vertical slats overlaid on top a newly designed insert and a beefier, sculpted bumper on the front.
The side of this prototype is bathed in camouflage but we are at least offered a view of sporty, five-spoke black wheels sitting over a set of beefed-up brakes. At the rear, the prototype includes a small spoiler stretching off the roof as well as quad tailpipes, which is typical of an AMG model.
The outgoing GLS 63 is fitted with a twin-turbo 5.5-liter V8 pumping out 577 HP. However, it seems likely that the new model will ditch this aunit in favor of AMG’s latest 4.0-liter twin-turbo V8. Despite the reduction in capacity, the new GLS 63 will at least match, but most likely exceed, the power of the current model and at the same time use slightly less fuel.
The cabin of the 2020 GLS 63, as well as the rest of the latest-generation GLS range, has been updated with a host of new features. For starters, the automaker’s MBUX infotainment system comes as standard with two large 12.3-inch screens and available full-color Head‑up Display. It also gets a number of semi-autonomous driving systems already featured in the E-Class and S-Class.
Although we have no official timetable just yet, we expect Mercedes to unveil the 2020 GLS 63 within the year, possibly as early as this summer, with a world premiere to likely happen in Frankfurt in September.
