Well we got to 4 nominations before the obvious “joke”…
By the way another nice move was done by Button on Alonso on lap 42 – he lost the position two corners later, and it was mainly thanks to Magnussen’s defense (as was the repass afterwards), but he went around the outside of Alonso in the last part of Les Combes brilliantly. But I don’t want to change my nomination, just throwing it out there.
Despite being an Alonso fan, I think rounding Pérez in Rivage was made a lot easier by the different aero configurations of the two car. Alonso’s high downforce kit enabled a lot more cornering speed than Pérez’s medium downforce aero package, just enough for Alonso to nullify the disadvantage the outside line meant.
Now one can say ‘blah, that’s not quite easy, just look at what Magnussen did to him’, but in the context of the Magnussen-Alonso battle we have to take into account the almost unbeatable traction of the MP4/29 out of low-speed corners. It’s not the first time this helped them preserve their positions (Malaysia against Massa, Barcelona against Massa and Silverstone against Alonso comes to mind).
…So I’d also go for Rosberg on Bottas. It was unnervingly difficult: being on the debris on the inside and being on the inside alone necessitated a much tighter line into Blanchimont and it required some skill – and bravery most of all – to complete the pass by not lifting at all.
