Because if the Mercedes-AMG GLS 63 simply is not enough, it leaves Brabus to make an explanation.
A quick answer to why someone would consider the Brabus treatment for their GLS 63 would be simply because the German tuner will make your full-size SUV much faster and louder.
Brabus will also add further fenders to the GLS 63, although this specific unit does not feature the extended body. Overall, the best thing to do in terms of power is the Brabus 850 XL model, which packs 850 hp instead of "only" 585 hp.
The Mercedes-AMG GLS 63 sprints at 4.6 km and 62 mph in 4.6 seconds and at 250 km / h (155 mph) at the camp. With a little help from Brabus, these numbers improve to 4.2 seconds and 300 km / h (186 mph) – make this thing just as fast as a Bentley Bentayga.
This particular car but only features Brabus cosmetic treatment, without any significant improvements in performance – according to the video description that this car calls a "Brabus 600" model.
Either way, exhaust is all the pony and crackling that should make this the loudest SUVs in the south of France.
