Last year, Mercedes lifted the wraps off the all-new GLE SUV to battle the BMW X5. This means it's only a matter of time before a next-generation GLE Coupe arrives to take on the BMW X6. We've already seen camouflaged prototypes undergoing testing, but this latest one has less camo than before. Luckily, our spies were able to get up close and personal with the GLE Coupe to provide us with our best look yet at Mercedes' new BMW X6 rival.

Compared to previous prototypes, the heavy plastic parts under the foil have been removed, giving us a better look at the sleek body lines and other details. The regular 2020 GLE also gives us a good idea what its Coupe counterpart will look like.

Thanks to its longer wheelbase, the GLE is larger than its predecessor and offers more interior space, although the Coupe's sloping roof may compromise some rear headroom and cargo space. The interior will also be equipped with Mercedes' latest MBUX infotainment system that features a 12.3-inch digital instrument cluster positioned next to an infotainment screen of the same size.

Under the hood, the new GLE Coupe will mirror all of the engine options available for the regular GLE. The base GLE350 gets a 2.0-liter turbo four-cylinder with 255 hp and 273 lb-ft of torque, while the GLE 450 is powered by a six-cylinder systematically electrified with 48-volt technology, delivering 362 hp and 369 lb-ft of torque. Thanks to that 48-volt mild hybrid system, an additional 21 hp is available for short bursts. Both engines are paired to a nine-speed automatic transmission.

There will also be hardcore AMG and AMG S variants, including a GLE 63 Coupe that will produce 603 hp and 627 lb-ft of torque in the range-topping S model. No word yet when the covers will come off the new Mercedes GLE Coupe, but we wouldn't be surprised if a debut is planned for the 2019 Frankfurt Auto Show in September.
