A Mercedes-Benz that's more powerful than an AMG? Is there such a thing? Apparently there is, and it produces nearly 500 PS from a specially-tuned bi-turbo V8.

Say hello to the 2020 Mercedes-Benz GLE 580, an amped-up mild-hybrid luxury crossover that serves as the most powerful GLE in the range.

Underneath its long hood is the familiar 4.0-liter, bi-turbo V8. But unlike its other stablemates, this particular engine gets a helping hand from electrification. Thanks to a 48-volt electrical system and integrated starter generator (ISG), the V8 produces 490 PS along with a stump-pulling 700 Nm of torque. Should one need more power from the already mighty V8, the aid of EQ Boost will add an additional 22 PS and 250 Nm of torque.

With these kind of figures, the GLE 580 easily trumps the GLE 53 built by AMG as its 3.0-liter twin-turbo inline-six only generates 435 PS and 520 Nm of torque. However, like the GLE 580, the AMG also comes with EQ Boost which adds an extra 22 PS and 250 Nm of torque when needed.

Does this mean Mercedes-AMG got beaten at its own game? Not to worry as the company is apparently working on an even more powerful model called the GLE 63. More than likely, it will have the same 4.0-liter bi-turbo V8; only this time, it will reportedly crank out 550 PS or more.

Don't fancy having a V8 under the GLE's hood? The all-new crossover is also avaiable with two other six-cylinder engine options; a 3.0-liter mild-hybrid turbo that produces 362 PS with 500 Nm of torque and a 3.0-liter turbo-diesel that punches out 272 PS with 600 Nm of torque.
