Here’s yet another custom Mercedes for you to drool at! With a 5.5-liter twin-turbocharged V8 engine hiding under the bonnet, developing 577 hp and 664 lb-ft of torque, no one could complain about the Mercedes-Benz S63 AMG Coupe is not exciting; however, aftermarket tuners are never satisfied with the standard package.

The following matte grey Mercedes-Benz S63 AMG Coupe, owned by the founder of ADV.1 Wheels, has received some pretty impressive upgrades; it now features a Renntech ECU upgrade. Basically, the rather simple ECU mods have managed to squeeze 701 hp out of the same engine. Furthermore, this S63 AMG Coupe is riding on a set of ADV15R Track Spec CS alloys, measuring 22×9.5 at the front and 22×11.5 at the back. You like?
