After one race this is a bit premature probably. Going off that one race McLaren are out in front in Qualifying, but then virtually matched in the race.
I think McLaren are just about quickest based on the first race, but the difference between them and Red Bull is tiny compared to what it was last season. If the race pace of both McLaren and Red Bull is similar, as Melbourne seems to suggest, then winning GPs is going to come down to which driver gets the breaks and takes their opportunities. McLaren dominating like Red Bull did last season would be just as bad for the sport. Similar pace will mean it's all up to the drivers, and that will mean top class entertainment and an enthralling season. And add to that the possibility of a few other teams knocking on the door and you have what might end up being a classic season. On a totally biased note I am very pleased that the most attractive looking car is also the quickest over one lap and the race (at the moment).
People on here talk crap. Schumacher was running 3rd before his retirement and he was going alot quicker then Roseberg and only about 3-4 secs behind hamilton.
