Official images of the 2013 Mercedes-Benz G63 AMG became available on the internet ahead of the vehicle's scheduled public debut at the Beijing motor show in China. This performance SUV features a deep new front bumper with huge cooling ducts, side-mounted exhaust pipes exiting ahead of the back wheels, characteristic five-spoke AMG alloy wheels and a double slat grille.
In addition, the G63 AMG joins the Mercedes-Benz range as a replacement for the long-running G55 AMG. The new model is run by the automaker's 5.5-liter twin-turbocharged V8 direct injection petrol engine.
This powerplant produces 536 bhp and an invigorating 560lb ft of torque, which means that this model has around 43 bhp and 44 lb ft more power than the old supercharged 5.4-liter V8 engine of the G55.
The recent powerplant is matched with a contemporary seven-speed automatic gearbox. Drive is channeled permanently to all four wheels via three separate differentials which can be manually locked from the cabin for greater ability in off-road conditions. In addition, the engine has brake energy recuperation and an automatic stop/start function for added fuel savings, unlike the other revamped G-class models.
Mercedes-Benz has yet to disclose any official performance claims regarding the new 2500kg-plus G63 AMG. On the other hand, it confirmed that the combined average fuel consumption is 20.5 mpg and its carbon dioxide emissions level is at 322g/km -- an improvement on the 17.9 mpg and 378 g/km of the G55 AMG.
A new range-topping G63 AMG model will be joining the G63 AMG in the refurbished G-class range. It is expected to be marketed in China, the Middle East and Russia, among others. It runs a 603-bhp variant of Mercedes-Benz's twin-turbocharged 6.0-liter V12 multi-point injection petrol powerplant, which delivers 737 lb ft of torque.
