13. Mercedes G Class G63 AMG 6×6
The Mercedes G-Class is one of the longest running models in the car world. They first introduced it in 1979 as a primarily military off-road truck and SUV, and it is still on the market today with the same basic design. During the course of almost 40 years, it survived many modifications and redesigns, but never changed its distinctive appearance and basic mechanical layout.
So, what do you do when you can’t modify the model anymore or make it more exclusive? Just attach a pickup truck bed and install one more axle to make it the fastest, most expensive and rarest 6X6 in the world. And that is how Mercedes created one monster of a truck.
The AMG 6×6 is a monster with its power and torque ratings and a monster by its sticker price, too. Under the hood is the 5.5-liter twin-turbo engine with 540 HP. Interestingly, it delivers power to all six wheels through a specially built automatic transmission unit.
