PHOTOS: Forget Your 4x4, It's Time For The SIX BY SIX: Mercedes Launches G63

Mercedes have unveiled a monstrous new rugged off-roader with six wheels - their first since a similar model was produced for the Nazis in 1930s Germany. The outrageous Mercedes G63 AMG 6x6 is a limited edition model based on the iconic G-Wagon. It has been designed to have the off-road capabilities of a tank, accelerate like a hot hatch and provide the luxury feel of a limousine. To give it brutal acceleration, Mercedes has replaced the standard G Wagon's 3-litre diesel engine with a twin-turbocharged 5.5-litre V8. The result is a 536bhp behemoth which is capable of 0-62mph in less than six seconds - despite measuring 19ft in length, weighing 3.85 tons. Mercedes claims the 6x6 - which has 37 inch wheels - can negotiate rocky terrain with 'all the agility of a mountain goat', while fording a river is 'almost child's play'. They add: 'Anyone exploring the on-road performance is certain to be impressed by the catapult-like acceleration of this 3.85-tonne pickup.' However, the 6x6 comes with a massive �350,000 price-tag - making it the most expensive model in the Mercedes range and three-times as pricey as a typical G Wagon. The off-roader, which is likely to be most popular in the Middle-East, will be limited to around 30 sales per year. The new model is not the first six-wheel off-roader from the German firm, with Hitler owning eight during the Third Reich. The G4 was a heavy-duty off-road car Mercedes produced for the German army between 1934 and 1939. Mercedes built 57 G4s during this period with heads of state and top military brass regarding them as a 'prestige all-terrain vehicle'.
