Smart SIXT —> long highway ride?

Hello together! and that’s what I asked you 😉 because leverkusen is in the cup finale*happy* I and my buddy bought tickets for the finale in berlin! now we thought about how best we come to berlin from Friedrichshafen (for all those who don’t know where this is on Lake Constance in the very south). despite the eigtl relatively high costs we have to rent 100 (100 euro rent with insurance protection, + sprit) for it to fire a car at sixt. and there is also the smar t fourtwo. now to my questions: 1. can you drive almost 700 km by car or is there a motor sample or something like that? 2. what is the consumption ? these are eigtl almost continuously by car, from fn only to lindau and from there only by car to berlin 3. does someone already have experiences with long car rides with nem smart? any unusual things sitting problems or something? would be really nice if you can help us!
