Renault admit in the current AE that the 172/182 was conservatively styled and that's why it it is virtually indistinuishable from the rest of the range.
However, the next gen RS Clio will be more like the willy/valver in that it's going to get a more bespoke body, rather than just some new front arches like the 172/182.
Obviously it still won't be as good but it's an improvement over the 172/182.
