Now celebrating its 30th anniversary, the mainstay of Mercedes’ 4WD line-up the G-Wagen is partying hard and has found a friend to celebrate with. Mercedes itself has released a pair of special-edition Geländewagens to mark the occasion (read news item). And now Brabus is preparing to storm the Geneva Motor Show with its own modified G-Class, and the figures are bordering on ridiculous.

Brabus has dropped in the twin-turbo V12 from the Mercedes S600, but bored it out from a massive 5.5 liters to a gargantuan 6.3. With the help of a new crankshaft, cylinder heads, custom exhaust, optimised intercooler and bigger turbos, the Brabus G V12 S Biturbo pumps out 700 horsepower and even more jaw-dropping 973 lb-ft of torque from just 2,100 rpm. Driving through a retuned five-speed automatic and all-wheel-drive, all that power is enough to propel the machine to 100 km/h in just 4.3 seconds. And despite having the aerodynamic profile of two bricks the monster can reach 260kph. Custom aero kit, lighting, wheels and electronics round out the package for a price that may be the most ridiculous number of all: 379,000 Euros, or about $940,000 in our money.
