An AMuS article says that the W03's (and Lotus's) development could be hampered due to the rules clarification on engine maps.
That is if Merc has planned to develop a coanda-type exhaust.
Coanda-type exhausts require and use modified engine maps that enhance the blowing effect for that type of exhaust.
The allowed 2.5% variation will not be enough to adapt the blowing.
Still, Ross sounded optimistic about gaining 0.4 sec after the summer break.
McLaren pioneered the Coanda-effect exhausts. They seem to do ok without the mapping allegedly required. I really don't know if Lotus had such an exhaust in its development plans, but I do not think it is that long a process to develop and implement one, as Sauber and Force India(?) has shown. So if there were plans, thee was plenty of time to design one, and implement it. I would rather suspect the opposite. Mc's fallback after the first few races seem to be down to reduced blow mapping, they had similar tyre problems to Merc. I would rather think that the halted development at Merc is more down to deciding wich way to go, I think they were waiting for this rule clarification, Mc ditto. There is something different coming through the pipeline from Merc, if this is true. AMuS, it seems has no insider info whatsoever from Merc, it is a shot in the dark, but in the wrong direction. I really don't envy the F1 journos this year, really. The amount of information seems to have decreased from every team, only the usual boring stuff ciculating everywhere, so everybody speculates. Which is fun here, on a BB, but hell in the editor's office. My two pence only, of course.
