It probably doesn't feel like it, but Alonso got lucky on Sunday. This picture shows the damage done to his rear left wheel in the collision with Petrov's Renault in the closing stages; Alonso is fortunate that neither the rim nor the tire failed.
Alonso got a lot of press for calling out Ferrari's seemingly glacial pace of car development this year. The car clearly isn't on terms with the Red Bull or McLaren cars, but behind that it is hard to tell. Massa was right there with Rosberg's Mercedes all day, and the Mercedes acted as a road-block for many cars following it for much of the race. Alonso puts the Ferrari on par with Renault. I personally think that the Renault is currently faster, but that mish-mash of cars in the Mercedes-Ferrari-Renault list makes it hard to tell for certain who is where.
Ferrari appears to be pinning hopes on a upgrade for Valencia, although the gerbil-maze nature of that event won't really showcase upgrades much, and we'd have to wait a few weeks before getting on to more traditional circuits.
