Mercedes-AMG 63S Coupe Doesn’t Escape G-Power’s Thirst For Horsepower

Whomever thought that G-Power is synonymous only with high-end Bavarian tuning has another think coming.

Sure, when it comes to infusing power under the hood, the German tuner has a soft spot for BMWs, but this particular Mercedes AMG63 S Coupe is one of the few exceptions. Honestly, though, who could’ve passed the opportunity to modify a 5.5-litre twin-turbocharged V8?

Not G-Power, obviously, which has a clear fetish for obscene power figures, and this new addition to its curriculum proves it.

With output bumped to 705 PS (695 HP) and 1000 Nm (738 lb-ft) of torque from the “measly” 585 PS (577 HP) and 900 Nm (664 lb-ft) of torque stock power figure, the big grand tourer sprints in 3.8 seconds from 0 to 100 Km/h (62 mph) on its way to the 330 km/h (205 mph) top speed – the 250 Km/h (155 mph) speed governor has been removed.

What makes the bump in power even more impressive is that G-Power used its Bi-Tronik 5 v1 plug-in play performance module, which means the car can return to its “normal” self after the gizmo is removed. Moreover, the engine protection and diagnosis functions are retained, and the power increase is activated only when the prescribed cooling water temperature is achieved, and temporarily switched off when the maximum permitted oil temperature is reached.

On the visual front, nothing except the AMG goodies announces the beast under the hood, as the tuning company decided to stay “incognito”, letting only the 9.0 x 21-inch Hurricane RR wheels do the talking on its behalf. Weighing only 11.4 Kg (each) the rims are made from 6061 grade aluminum – a material favored by the aerospace industry for its unique combination of low weight and high-strength – reducing unsprung mass and aiding the vehicle’s performance.
