Its Panamericana grille is partly covered, but its shape appears basically flipped upside down compared to the current car. We also get a glimpse of its performance brakes under its big black wheels. These will complement the twin-turbocharged 4.0-liter V8 under the hood. In back, it looks like the bumper will get a different shape, though it's hard to tell what's hiding under that camo. We see a pair of exhaust pipes sticking out, but we expect those to manifest as quad exhaust tips on the production version.
We're likely to see a GLE63 with 571 horsepower, with a possible GLE 63 S with 612 horsepower. This will be followed by a GLE 63 Coupe, but the lack of any sightings of that version means it's likely not as far along in its development.
