Four-wheel drive

If it is said about some firm that it created all-wheel drive cars, then it is, certainly, Audi.


The VW Iltis all-terrain vehicle developed by Audi by request of the Bundeswehr for VW became a germ of the idea of Quattro. The legend so tells about it:

During a winter trial trip in the north of Sweden such Iltis with the weak engine caught up and overtook much more powerful and high-speed Audis with the forward drive. The head of test of that time of a running gear initiated work on creation of "the all-wheel drive car of decent power for daily operation". It is known that nothing will be compared on force to the idea which time came therefore developments proceeded and continued until, at last, legendary Audi Quattro was not presented.
