Hello,
can anyone help me finding these fonts of the numbers used on these RedBull Racing F1 cars?

Thanks in advance!

Futura Condensed  Sugerida por fmontpetit 

Futura Condensed seem to match except for the number '2' on this pic : http://www.f1fanatic.co.uk/wp-content/uploads/2011/02/redb_rb7_2011.jpg

It really looks quite similar - more than any font I've found so far. Thank you a lot, fmontpetit!
