Vettel on top in first practice at Hungary

F1 Grand Prix, GP Hungary, Hungaroring

Sebastian Vettel went fastest in today's first practice session in preparation for the Hungarian Grand Prix. His teammate Mark Webber was second fastest, ahead of title contenders Kimi Raikkonen and Fernando Alonso.

As ever, the first session was about testing and part validation, with many teams doing runs with aerodynamic measurement equipment and flowviz on the cars.

The new tyres have also played an interesting role. Williams for instance had ditched their blown wheel nuts as they are now redundant, knowing that they were specifically developed to cope with the 2013 tyre construction. As the new tyres are built on the 2012 kevlar construction, the hubs are now redundant and would cost too much to redevelop, knowing that most teams are have switched most of the development capacity to their 2014 projects.

McLaren also appeared to be going rather well, which Sam Michael states is due to the camber and pressure limitations that are in place since Germany. The lack of movement in this area reduces the advantage some cars had over the McLaren MP4-28.

Only one reserve driver meanwhile was in the car this session, as Rodolfo Gonzalez was allowed a run in the Marussia, instead of race driver Max Chilton. The latter will be back in the car in FP2.
