This marks the first time we’ve spotted the flagship AMG-powered version of Mercedes’ upcoming GLE Coupe model, which until now has only been captured on camera in lower trim AMG 53 and regular specs.

Compared to the 53 model, the 63 should perform considerably better, given how much power and extra torque it produces. So while the former is expected to pack some 435 PS (429 HP) and 520 Nm (383 lb-ft), the 63 version will likely replicate the E63’s 4.0-liter V8 setup, in two stages of power.

The GLE 63 should then pump out 571 PS (563 HP) and 750 Nm (553 lb-ft) of torque, whereas the 63 S version will raise the stakes even higher, with 612 PS (603 HP) and 850 Nm (627 lb-ft) of torque of its own, everything going to all four corners with the help of a nine-speed automatic transmission.

Thicker all around

Unlike the regular 2020 GLE Coupe, this particular prototype sports a chunky front bumper with large air intakes, wider fenders, side sills, massive brakes and a Panamericana grille. Out back, we can see four square exhaust pipes, unlike the four round ones spotted underneath the rear bumper of the GLE 53 Coupe prototype.

While this is just a guess, seen as how the current GLE 63 S can accelerate to 100 km/h (62 mph) in 4.2 seconds with 585 PS (577 HP) and 760 Nm (560 lb-ft) of torque at its disposal, we reckon the all-new model will either much or perhaps shave a tenth of a sec, which would be a pretty stunning accomplishment for such a large crossover.

As for what we can expect inside, the flagship model of the GLE Coupe range will retain a dual-screen setup for the dashboard, grab handles for the center console, as well as the automaker’s latest software and on-board tech.

According to sources, Mercedes will launch the GLE 63 Coupe later this year, with rivals such as the BMW X6 M and Audi RS Q8 in its sights.
