in the rear row of a normal family car fitted securely you simply need to take time in choosing 3 seats apropriate for your childrens size/age of a size and shape that fit side by side nicely. there will def be 3 that fit nicely in your Passat (the Fiesta was just an example to illustrate size of car).. Another vote for the Multipla. 3+3 so you can put the kids in the back and the centre front seat will fold down to a table so you can lean through the middle to attend to them. I think the rear centre seat can also slide back and forth which may give more wiggle room to fit bulky child seats.
