The post-qualifying car weights in Budapest ahead of this weekend's Hungarian Grand Prix as published by the FIA have corroborated pole-sitter Fernando Alonso's admission that his Renault will be light on fuel when the starting lights go out at the Hungaroring on Sunday - but provided Sebastian Vettel alongside him on the grid can get away well, by contrast, the young German looks to be the man sitting in the pound seats.

Whilst Alonso's R29 weighed in at just 637.5kg at the end of a chaotic session at the Hungaroring, Vettel is running almost 20kg heavier - and, what's more, heavier than Red Bull Racing team-mate Mark Webber to-boot, with the Australian - F1's newest grand prix-winner following his peerless N?rburgring triumph a fortnight ago - carrying four kilos less fuel aboard his RB5. In other words, if Vettel does not encounter any difficulties at the start on the dirtier, less grippy side of the grid, then the race could well be his to lose.

One other problem for the young German, however - or rather two other problems - are the two McLaren-Mercedes' of Lewis Hamilton and Heikki Kovalainen. Though respectively one and two rows behind him, both will have the benefit of a KERS power boost at the start, and in Germany that was enough to propel the British star from fifth to first by turn one, even if he did then leave his braking too late and head straight on. Kovalainen in particular seems to have a decent amount of fuel in his car, so a good start for the Finn could upset the applecart considerably.

Elsewhere inside the top ten, both world championship leader Jenson Button in eighth and Kazuki Nakajima just behind him on the grid in ninth will be running long opening stints - in contrast to the Ferrari of Kimi Raikkonen, behind the wheel of the third-lightest car in the field on row four - whilst Williams' Nico Rosberg seems to have a sensible strategy aboard his Williams, and if all goes to plan should be well in the mix for a rostrum finish at the chequered flag.
