Some really interesting bits of news coming out over the past few days. Firstly, as I mentioned
here (over in the Ferrari thread) the LaFerrari test mule has been back on track.
As reported by Omnicorse (full article
here), the car has had significant mods made to it.

There is clearly a single exhaust seen and lots more downforce added to the car. This will be for extended testing at higher (more f1 like) speeds. You'd think the ERS is also integrated and running. If you look closely you can see the ERS sticker on the side of the car.
This is very good news that the team is well advanced in terms of having the total package running on a track.
The other interesting take away from this article and recent comments from Luca is we can definitely be optimistic that Ferrari is planning a return to LMP1. They will have plenty of cash and LM racing has no budget caps.
