The rain on Friday has screwed up McLaren's plans of evaluating the blown diffuser in the dry. They needed a dry Friday to collect and evaluate as much data as possible. McLaren had to play a gamble on whether to run a blown diffuser for the 2nd half of the season as their original package was already very strong to begin with.
As for Red Bull, they had 2 "new" front wings on Friday, and on Saturday morning 1 more will be flown in (making it 3 in total), and 1 more to be flown in on Sunday morning (4 in total).
Felipe was leading the Germany GP before an obvious and clear decision was made by the Ferrari team to let Fernando through. Felipe also did it in such a way to let everyone know he let Alonso through by deliberately slowing on the exit of turn 6.
As a result, Ferrari have been fined US$100,000 by the FIA after race stewards deemed they had breached sporting regulations. The case has also been referred to the World Motor Sport Council (WMSC).
Ferrari driver Felipe Massa, who had been leading the Hockenheim race, moved aside to allow team mate Fernando Alonso past on Lap 49. A few moments before, Massas race engineer Rob Smedley had told the Brazilian "Fernando is faster than you. Can you confirm you understood that message?"
Although Ferrari maintained this did not constitute a team order, the stewards decided the Italian team contravened Article 39.1 of the sporting regulations, which regulates against team orders, and Article 151 (c) of the 2010 FIA International Sporting Code, which relates to bringing the sport into disrepute.
The decision will also be forwarded to the WMSC for its consideration, meaning Ferrari could in theory face further sanctions.
