We could talk millimetres of headroom, wheelbase and such like, but in order to really get a handle on the size of the Turismo's body, consider this. In some world markets, this design can be sold as an eleven-seater! Therefore, when you 'only' try to accommodate seven people, you have a fairly unconfined amount of breathing space. In case you're interested, the wheelbase measures 3,000mm, which is about the same as a Mercedes-Benz S-Class, but the huge rear overhang means this SangYong is significantly longer than something like the latest Range Rover.
This helps solve that problem inherent in most seven-seat MPV-style vehicles. Namely of having no luggage space available when all the seats are in use. In fact, there's more room in the back of the Turismo with all the seats in place than you'd get if, in the same configuration, you combined the luggage capacities of a Ford Galaxy, a Vauxhall Zafira Tourer and a SEAT Alhambra. There are three rows of seats as well as a large load area which can be further increased by removing the third row completely. The second row of seats can be folded individually and used as tables and there is still sufficient room to accommodate airline-style seat back folding tables.
