AMG has a knack for tuning Benzes, to say the least. And that includes Mercedes' crossovers. So when the Silver Star releases a new one, we know it'll only be a matter of time before the performance version arrives. And the latest is the new GLS.

Following the new three-row sport-ute's reveal in New York last week, these renderings by the prolific Nikita Aksyonov give us a pretty good idea of what to expect – visually speaking, at least – from the inevitably forthcoming Mercedes-AMG GLS63. And it's sure to be a big brute of a machine.

Where the outgoing GLS63 packed the old 5.5-liter twin-turbo V8, we can expect the new model to switch to the latest 4.0-liter unit. That ought to give the seven-seater upwards of 500 horsepower and 500 pound-feet of torque, depending on which version Affalterbach opts to slot into the new GLS. In the latest GLC63, that engine produces 469 hp and 479 lb-ft, or 503 hp and 516 lb-ft in the GLC63 S Coupe. But the new GLS63 could very well get the still more potent version from the G63, kicking out 577 hp and 627 lb-ft.

The latter would make it just as powerful but even torquier than the outgoing model that was upgraded to 577 hp and 561 lb-ft a few years ago, delivering a 0-60 mph time of 4.6 seconds.

Whatever the engine, we'd expect the new GLS63 to be even quicker off the line than the old one – even if it is bigger, now riding on a 123.4-inch wheelbase that's 2.4 inches longer than before. It'll have to be, considering that the new GLS580 already packs 483 hp and 516 lb-ft, with 21 more horses and 184 more lb-ft unleashed by the 48-volt EQ Boost system.
