Like its arch rivals from BMW and Audi, namely the X6 and Q8, the Mercedes-Benz GLE Coupe is, in range-topping AMG GLE 63 S guise, a beast of an SUV courtesy of its 5.5-liter, twin-turbo V8 that produces 585 PS (576 hp / 430 kW) and 760 Nm (561 lb-ft) of torque.
We can’t think of anyone complaining for lack of performance, but some will always want more. G-Power is catering tho those and managed to obtain a very impressive 800 PS (789 hp / 588 kW) and 1,100 Nm (811 lb-ft) of torque thanks to new turbochargers, an aftermarket exhaust system, new software and other optimized or new components.
Unfortunately, they didn’t divulge how quick the tuned GLE 63 S Coupe is to 100 km/h (62 mph), but the stock item needs just 4.2 seconds. The top speed limiter has been removed, so it will surely go beyond the 280 km/h (174 mph) top speed of the factory model fitted with the optional AMG Driver’s Package.
The tuner has made it more striking with the decorative stripes and other elements, adding their logo on a few parts, like the tailgate, engine cover and rims. The latter are part of the Hurricane RR line, boast a five double-spoke pattern with monochrome finish in jet black, measure 23 inches in diameter and are shod in 315/25 tires.
Upgrading your GLE 63 S Coupe isn’t going to be cheap, as the power upgrade alone comes at €19,130 ($21,087) in Germany. Increasing the V-max is a €595 ($656) option, whereas the stainless steel exhaust system will set you back €4,600 ($5,071). G-Power is offering an interior makeover too, with leather upgrades and a couple of steering wheel designs to choose from.
