Different kilometers between XC60 MJ 2016 and V60 2 MJ 2019 early on the same route

Moinsen, we have the vehicles mentioned in the thread title and are very surprised by the considerable deviations in the route. The route is according to Google maps 431,2 KM long. So far we have removed 12 identical journeys; each car six. My car, the XC60, arrives at 431,1 to 432,0 KM. My wife’s car, V60 2, shows after the identically driven route 443,2 to 445,9 KM. We have observed this phenomenon again and again and we are slowly worried about it. So far we have not been with the friendly one, but we consider it. The deviations occurred with both summer and winter bikes. So it can’t be that. Can something be “adjusted”? Thank you for tips.
