German speakers use the word "Touring" spelled just as it is in English; one can, however, also find "Tourenwagen" and "Touren" used in German texts (and in my big two volume Langenscheidts dictionary). Apparently they have taken the early 20th century notion of a "touring car" and continued it for any vehicle which has a long roof extending all the way from the windshield to the back end, without a trunk, because the aforementioned Swiss cousin's pride and joy, a collectible early '70s BMW 2002tii Touring, had the word spelled out just that way on its rear end, but that particular model would be almost into the realm of what we would call a "hatchback" in the USA, if the 3rd "door" sloped a little more. This could be confirmed by going to a German language BMW or Mercedes site to see how the models are described.

On the back end of an old '66 Maserati, on the other hand, the word "Touring" referred to the Italian body builder.
