Facelifted S-Class reveal date also confirmed.

It’s official. Mercedes has quietly announced plans to host the online premiere of the GLC 63 and GLC 63 Coupe on April 5th. We’ll have full details, images, and videos of the high-performance compact crossovers on Wednesday, ahead of what will likely be a public debut at Auto Shanghai 2017 on April 19th, during the first press day.

The beefiest GLC of them all will pack a biturbo 4.0-litre V8 engine and will arrive to make up for lost time: the previous GLK never spawned a fully-fledged AMG version. Details about how much power the eight-cylinder motor will deliver are not available at this point, but the unit pushes out 503 horsepower and 516 pound-feet of torque in the C63 S models. Needless to say, the output will be channelled to a 4Matic all-wheel-drive system, as is the case with most of the '63'-badged models.

Mercedes-AMG boss, Tobias Moers, has already revealed the crossovers will be blessed with the E63’s drivetrain, but that doesn’t necessarily mean the V8 will be tuned to the 603 hp and 627 lb-ft punch of the new E63 S. The head honcho from Affalterbach might’ve referred strictly to the E63’s new AWD system and nine-speed automatic transmission.

As for the other hotly anticipated debut scheduled for this month, the S-Class facelift will be out on April 18th, just one day before the show in China will open its doors. We’ve extensively covered the revised range topper in a recent article, talking about its new inline-six petrol and diesel engines as well as a new biturbo 4.0-litre V8.

Some cosmetics tweaks for both the interior and exterior are on the agenda, along with additional safety tech and improved driver aids. It’s not known at this point which versions of the 2018 S-Class will be revealed, but chances are the hotter AMG S63 and S65 will be launched later in the year. Similar revisions for the S-Class Coupe and Cabriolet, as well as for the plusher Maybach-badged model, should follow shortly.
