Anybody who’s put the pedal to the metal in a Mercedes-Benz G63 AMG knows just how determined this military-roots machine is to show you that it can dive into the triple-digit speed area as if it would cancel its weight and size with anti-matter. This is one of the reasons for which the G63 is hugely popular in Dubai and now it’s time to see how the people over there like to tune the Gelandewagen.
How do 728 hp and 1,052 Nm (776 lb-ft) sound like? This is what aftermarket specialist Simon Motorsports pulled off and they’ve got the dyno run to prove it. To be more specific, the Affalterbach machine was placed on the dyno before its tech side was touched, showing 563 hp and 776 Nm (572 lb-ft), very close to the official specs. By the way, the twin 776 numbers are amusing, aren't they?
