The Mercedes tuning specialist Brabus has revealed a performance package and an aesthetic kit for the mighty 2013 Mercedes Benz G63 AMG. 
The latest program attempts to make the extreme wagon even more hardcore by adding a new set of wheels and boosting power.
In fact, the usual power (544 HP or 400 kW) of the e V8 5.5-liter bi-turbo engine has been increased to 620 HP (456 kW). Also, the torque figure is up too by 40 Nm (29 lb-ft) to 800 Nm (590 lb-ft). 
Another good and new thing is that Brabus installed a new set of huge 23-inch, twin-spoke alloy wheels and painted the brake calipers in yellow. Other features include the ride control comfort suspension and valve-controlled exhaust system.
