Mercedes-AMG GLS 63 Spotted With Long Overdue Refresh

Spy Shots

The largest AMG is finally getting an update.

BMW may have decided against offering an X7 M but at least Mercedes offers an AMG version of its three-row GLS SUV. Mercedes introduced the GLS 63 back in 2013 and it now produces 577 horsepower and 561 lb-ft while hitting 60 mph in just 4.5 seconds. These performance figures are ludicrous for a seven-seater SUV, though you may want to think twice before dropping $126,150 on one.

The GLS is pretty much the most dated model Mercedes sells in 2019. Inside, the GLS features a Comand infotainment system that is now two generations old and under the hood, the GLS 63 still uses the old 5.5-liter twin-turbo V8 rather than AMG's new 4.0-liter unit.

But if the idea of an AMG-powered three-row SUV just sounds too appealing to pass up, we've got good news for you. Our spy photographers recently captured images of the new GLS 63 testing. The details about this new model are limited but we can clearly see it sporting the AMG Panamerica grille found on other models like the AMG GT and S63. We can also pick out revised headlights and taillights, which should look more in line with other recent Mercedes models. Out back, the GLS 63's soundtrack will exit through AMG quad exhaust tips, which add plenty of drama to the seven-seat SUV.

The spy shots don't give any indication of what's under the hood but it's safe to assume AMG's 4.0-liter twin-turbo V8 will be the engine of choice. In the E-Class, this engine produces over 600 hp mated to a nine-speed automatic transmission. If this is the chosen drivetrain for the GLS 63, we expect it to be even quicker than the current model from 0-60 mph. We don't know when the new GLS, GLS 63, and rumored Maybach version will debut, but the 2019 Frankfurt Auto Show in September seems like a good guess.
