Your friend seem to have a heavy foot .... but then I never really trusted digital displays much .... it could go up or down drastically depending on how the car is being driven.

you might want to have your friend check her car at the SC. When I had my 4 speeder, I too got around 12l/100km like the rest of the forumers here ... perhaps she's constantly stuck in traffic

Too bad the 1.4 TSi does not come with launch control. Not that it would surprise many if a Golf were to outsprint anyone else at the traffic lights .... but to see an old Skoda Octavia II pulling just as fast off the line can be quite fun.
