There are many brands sitting unused- BMW own the Triumph name (Cars not bikes) and many feel that a new Spitfire would sell well here, even if it was, for example, a reworked Z4 because people who wouldn't buy a BMW might consider a Spitfire.... There are many more examples of unused names most of which will never be seen on the back of a new car again.
Apart from anything else, if Renault did build a new Alpine we could have a lengthy discussion about why it's not a 'real' Alpine...
