All-new SUV flagship outed online ahead of its motor show debut, looking very much like a GLE that's done a few sessions at the gym.

The new-generation Mercedes-Benz GLS has leaked online in a series of images, ahead of its full reveal in New York later this week.

Like the BMW 1 Series earlier today, it seems someone just can't wait to show off the new SUV to the public, with the images originally published by the Middle East's Almuraba, and reposted by Carscoops.

Mercedes-Benz's answer to the BMW X7 follows a very similar formula to its arch nemesis, in the sense the GLS looks very much like an enlarged version of the GLE – because that's pretty much what it is.

We don't have official specifications yet, but the GLS will be quite a bit longer than its GLE sibling, and doesn't have the same C-pillar design that harks back to the original ML like the GLE does.

It does, however, follow a similar design language to its smaller sibling, with notable differences being the LED daytime-running light signature, and three 'squircle' cutouts in the front skid plate element compared to the GLE's more rectangular design.
