UPDATE: Australian sale launch confirmed for June 2012.
The AMG-enhanced ML is driven by the company's new 5.5 litre "biturbo" V8 engine, delivering 386kW and 700Nm of torque - up from the 375kW and 630Nm of the current model.
Power is sent to all four wheels through the AMG Speedshift Plus seven-speed auto, and fuel consumption is listed at 14.7 l/100km - down from 16.5 l/100km for the Australian-delivered current model.
Tick the AMG Performance Package box, and power is boosted to a nearly ridiculous 410kW and 760Nm.
In its regular form, the new ML 63 AMG will catapult to 100km/h in 4.6 seconds - beating the old one by only just a hundredth of a second - and top speed is up from 250 to 280km/h.
Keeping AMG's new ML on the road is a new active roll stabilisation system that forms part of the AMG sports suspension system, along with Airmatic air suspension, automatic level-control and adaptive damping.
Along with the tougher exterior styling and massive wheels, the ML 63 AMG gets the usual interior enhancements, including leather trim and a black headliner, AMG sports seats and a leather-wrapped AMG steering wheel.
The sub-AMG range-topper in 2012 will be the V8-powered ML 500, producing 300kW and 600Nm of torque.
Mercedes-Benz Australia has confirmed the ML 63 AMG will hit local showrooms in June next year, shortly after the arrival of the new M-Class range.
