Brabus tuning company is an avid fan of AMGs. Not that these SUVs need more power but adding more horses surely makes them more attractive.
The latest tuning kit prepared by them for the AMG GLE 63 S is called the B63S 700.
Brabus boosted the 5.5-liter V8 from 577 hp to 690 hp, and the torque to 708 lb-ft. This accelerated the SUV to 62 mph in mere 4 seconds flat. They also capped the speed at 186 mph.
This enormous power boost was obtained by adding 2 turbochargers with large compressors, a new exhaust and re-mapping the injection and ignition.
