As a previous poster said, "Gallardo."
It's still a very clean yet aggressive design, and the Gallardo resemblance could probably be lessened by a bit of resculpting. The real question remains--how can Lotus become part of a larger, better-funded company, but one which will let it alone to do what Lotus does so well?
As Sergio has cheapened the Ferrari brand (lots of trinkets for sale, development of an SUV, ever-higher production volumes), I'd like to see Lotus move up the food chain. It would take years of sustained effort, but it seems it would be doable.
