It may look impractical, overweight and expensive as hell. But while it is all those things and more, the Mercedes-Benz G63 6X6- which has now arrived in the US- is also devilishly fast and capable of ascending, fording or crushing just about anything. The 8,322lb monster uses a 5.5-liter bi-turbo V8 to move it from 0-62mph in 6 seconds. It also produces 536 horsepower and 560lb-ft of torque, using a 7G-tronic transmission to send power to all six wheels.

The six-by-six beast derives from the C320 CDI, designed and developed for the Australian army. Its brutish dimensions extend almost 20-feet in length, 7-feet wide and 7.2-feet tall, the two extra wheels adding 43-inches over already-massive standard G63. The car costs $525,000 in Europe, so if you plan to grab one of the 20-30 to be built each year, expect to part with some serious dough. Spotted in America wearing German plates, it looks even more badass then its impressive specs would imply.
