Betty, that's the whole point: these fonts do not exist!
The separate letters needed for the logos were drawn,
but there is no full alphabet in digital form that you
could use to make your own text with. Sorry, can't help it.

For Opel, you could consider using Eurostile; for Vodafone
try ITC Avant Garde Gothic; Siemens I'd have to look for
something; and Pirelli maybe Franklin Gothic which you
should stretch yourself.

Thank you very much Yves Peters, you are so good..i will looking for pirelli[s font

not sure, but i guess nearly all 4 are corporate fonts (opel and siemens are for sure). the opel one was done by robin nicholas and is available via agfa monotype ... but your example shows the old logo by the way.
the siemens one was done by hans-jurg hunziker and is available via urw.
no idea about vodofone, but the pirelli one is quite old. hth: lars
