Volkswagen Passat, Peugeot 508, 2018-2019 versions. Both of these are sedans whose back seats fold down. 2013 Ford C Max. I assume the 2018-2019 versions will fit a tandem but don’t know that for sure. You will have to take both front and rear wheels off to get a tandem in these vehicles. In the C Max the passenger’s seat will have to be moved forward a couple of inches. Like the Passat and the 508 the C Max rear seats fold down. These are vehicles we’ve rented in Europe. We put our Bike Pro Tandem case in first and lay the tandem on top of it. With the handle bars turned sideways we need right at 72” of space for our tandem to fit inside. The Passat and 508 have 80” of space. The C Max has been the easiest to get the case and tandem in and out of.
