I've only just caught this story (was away last week & missed it).
So - the grand CFD experiment has ultimately been deemed a failure then. A pity in a way, but one hopes that Pat Symonds can steer them onto a more successful path (presumably a reasonably cost-efficient one, given how frugal Renault used to be).
The McLaren tie-up is interesting too - I thought Force India used a McLaren back end, rather than a Mercedes one?
