Mercedes-Benz has confirmed plans to build 20-30 units of the 6x6 G63 AMG every year.
The exotic three-axle G-Class will be approximately three times more expensive than the regular G63 AMG (137,000 EUR), making it the second most pricy Mercedes-Benz model after the SLS Electric Drive (416,500 EUR). It is expected to go on sale this October.
According to Autoweek, the car is based on the G320 CDI developed for the Australian army and is 5867mm (231.3 inches) long, 2111mm (83.1 inches) wide and 2209mm (87 inches) tall, which makes it 1105mm (43.5 inches) longer, 226mm (8.9 inches) wider and 272mm (10.7 inches) taller than the standard 2013 G63 AMG.
The military version has a 3.0-liter diesel engine and a five-speed automatic version but this civilian model sports a V8 5.5-liter bi-turbo engine producing 536 hp (400 kW) and 560 lb-ft (758 Nm) of torque. The power unit is linked to a seven-speed 7G-tronic transmission.
Chief of G-Class development Axel Harries says the car will do 0-62 mph (0-100 km/h) in less than 6 seconds on its way to an electronically-limited top speed of 100 mph (160 km/h). He also mentioned the 6x6 G63 AMG returns 13 mpg US (15.6 mpg UK or 18 liters / 100 km).
It boasts an impressive ground clearance of 460mm (18.1 inches) and weighs 3,775 kg (8,322 lbs). It rides on huge 37-inch wheels, with approach and departure angles of 52 degrees (up by 16) and 54 degrees (up by 27), respectively. It also has a stainless steel roll cage and a payload capacity of 650 kg (1,433 lbs).
