i need to know what the new Renault font is called (and idealy somewhere to download it?).

The logo font at the top on this page http://www.renault.co.uk/CurrentCarRange.aspx

Not to disappoint you - or make your day miserable, but Renault commissions typedesigners to create an original font for them. And it isn't available to the public.

There are a few fonts you could use that are similar.

Unless the public also wants to play with the LuMarcâ„¢ Bold.
