G63 AMG The new Mercedes 6X6 is built on the chassis has my father designed in the 80s. My father made prototype 6 wheels since 30 years on mercedes of course because it is his favorite brand, but also Range Rover, Renault, Peugeot (P4 is the same chassis).
He tested prototypes of all the Paris-Dakar race, between 1981 and 1986, all cars have arrived in Dakar without changing parts, and in good condition.
Unfortunately my father does not speak English, he can not answer you, but I can translate it if you have questions.
Have a Good day
