From a commercial point of view I think Renault are setting themselves up for failure. From a technical/competition point of view I think it's wonderful that this Enstone team once again have funding to bare their claws.
If you doubt the commercial prediction then remember that the GEN II investors have lost a fortune in this team. Renault is buying it from them for... a tiny shareholding in the business going forward. The only question is who's next to blow money via naïve optimism. Renault has raised their hand...
From a competitive point of view the team's great successes, though the product of many talented people, can be remembered by the successes of their drivers. So-- Toleman (Senna), Benneton (Schumacher), Renault (Alonso), Lotus (Raikkonen), and now Renault again (who's next hero?). Raikkonen didn't win a championship with Lotus, but he did win several races against several better funded teams. For sure the underdog success story of 2012-2013.
And finally, good riddance to the Lotus name, just a pure abstract brand that did no justice to the team and its history. I do like the Renault name much better because come success or failure the Renault company really has their ass on the line. Got to respect it.
