Hello together… On the internet you can find some tests of the different four-wheel systems at the moment, the comparison Quattro vs Xdrive… Unfortunately the Quattro fails in this role test In different forums the Quattro would have been overtaken by Xdrive and 4Matic for a long time.In another test, if ́s it ́s important then the Quattro is still in the lead.For sure each system has its advantages and disadvantages… But what do you think? Which system is the now really the better ? Greeting, Oliver
