Aero update for Alonso


McLaren will bring a large aerodynamic update to the Austrian Grand Prix in Spielberg this weekend.

The update, of which only one is available, will be used on Fernando Alonso's MP4-30. Any advantage it brings him however, will be negated by the fact that McLaren have decided to perform an engine change on his car. He will in all probability, start from the back of the grid. 

Alonso will also be testing in Austria in the week after the race, so racing with the updates will give McLaren valuable insight before the testing session takes place. Updates include a revised nose and a new floor amongst other tweaks.

Earlier this year, Jenson Button was the recipient of updates to his MP4-30, so it would appear that McLaren use a rotational policy when only one update package is available. reports that McLaren may opt to change Button's engine as well, but that this will only be decided after Friday.
