Brabus is known for its mighty powerful builds. They are unlike any other aftermarket companies and tuners, and are one of the most expensive ones out there. So, when the good folks at ‘Carwow’ brought a Brabus creation to the race strip for some fun, it piqued our interest. Called the Brabus 850, it was a jacked-up Mercedes-AMG GLE 63 with oodles of performance upgrades. It went up against a Lamborghini Urus and a Tesla Model X Performance. On paper, it is the most powerful of the lot. But, was it the same in the real world as well?
