The facelifted Mercedes-Benz E-Class is no longer a secret and that includes the E53 performance model unveiled last month.

However, there’s still one member of the refreshed E-Class family that remains to be unveiled and that’s the E63 full-blown AMG model. We’ve already seen shots of undisguised 2021 E63 prototypes but now we get a clearer picture of what to expect thanks to fresh spy shots.

In these images taken at the Nürburgring, we see an E63 sedan prototype with less disguise than ever before.

The rear end is completely uncovered, allowing us to spot the new taillights which look identical with those of the facelifted Mercedes-AMG E53. The difference is the E63 features squared-off quad taillights instead of round ones, while the boot lid spoiler is more pronounced than on the E53. We can also see a chrome bar above the tailpipes and the rear diffuser.

At the front, the 2021 Mercedes-AMG E63 adopts a bigger iteration of the Panamericana grille and a slightly more aggressive front bumper. As you can see, the front end and a portion of the front fenders are the only parts of the vehicle that feature camouflage.

Elsewhere on the prototype we can spot a new set of AMG wheels and uprated brakes. There are no photos of the interior but we don’t expect to see major changes compared to the E53.

As for the powertrain, Mercedes-AMG will stick with the twin-turbo 4.0-liter V8 offered in two states of tune. Currently, the eight-cylinder unit makes 563 HP (571 PS) in the E63 and 603 HP (612 PS) in the E63 S – we don’t really think a power boost is necessary.

Expect the facelifted 2021 Mercedes-AMG E63 and E63 S sedans and wagons to debut later this year, probably in autumn.
