Does this Speed Hack really work?

Hi, it's my first post here. I'd like to ask a question about a Need for speed world car speed hack. I need to know if this hack really works .My friend tried it and he told me he works but I can't really believe him. I need a really quick answers from someone who tried it. I think that the hack is virus free but I don't know if it really works :S.

Check this video about the hack.
Thank you
