The FIA's publication of the post-qualifying car weights for this weekend's German Grand Prix at the N?rburgring is likely to raise more than a few eyebrows within the F1 paddock, with any suspicions that Mark Webber ran light in order to seize pole position swiftly dispelled and a number of surprises elsewhere inside the top ten.

The two lowest-fuelled cars in the field, indeed, are the Brawn GPs of Jenson Button and Rubens Barrichello, respectively third and second on the starting grid. Though it is unusual for the ex-Honda F1 outfit to go light in the final Q3 phase of qualifying, given the famously unpredictable weather in the Eifel Mountains region, it could be that the master tactician Ross Brawn is pinning his hopes of victory on an early rain shower or safety car to spice up the action and shift the advantage back in his eponymously-named team's favour.

Webber's car weighed in identical to that of team-mate Sebastian Vettel, with the home hero having admitted to underperforming in what he described as a 'lottery' - but more importantly for RBR, the pair are 17kg heavier than Button and carrying 14kg more fuel than Barrichello, a difference that could make all the difference on race day given the relatively small gaps between the lead quartet in qualifying.

The enthusiasm of McLaren-Mercedes team principal Martin Whitmarsh for the performance of Heikki Kovalainen - out-qualified by team-mate Lewis Hamilton by more than a second as the two Silver Arrows annexed the third row of the grid, though conversely not benefitting from the full aerodynamic upgrade package brought to the British star's MP4-24 this weekend - is perhaps explained by the fact that the Finn achieved P6 despite carrying almost 10kg more fuel on-board than the reigning F1 World Champion.

Another driver to shine was Adrian Sutil, who looked mightily impressive in snatching seventh spot - Force India's breakthrough Q3 appearance in its brief history in the top flight - even before it was revealed that he did so with the heaviest car of any of the drivers in the front half of the field. Assuredly, points for the likeable young German on race day would be the very least he and the small Silverstone-based squad deserve...
