new mini is just used to make it clear that people are talking about the "2nd generation" mini, i don't see any harm in it.
for a lot of people, me included, part of the attraction of the classic mini is the fact that it never really changed. unlike the ford escort or VW golf they really are pretty much the same car over the production run. that puts them in the same class as the VW beetle.
And like the 'New' MINI there is also a New Beetle, now on it Mk2 version I think?.......however like the 'New' Fiat 500 the 'New' Beetle has a completely different layout to the original car,
ie. the Beetle and Fiat 500 are no longer rear engined or rear wheel drive anymore......they are both transverse front engined with FWD, so Alec Issigonis's layout triumphed in the end and the New MINI's like most other modern small cars use his ground breaking design concept as the best for space and handling, etc. Likewise John Cooper's rear engined race car layout triumphed in single seater racing cars and F1.
