Formula one teams are gearing up to shut down their factories.

At some point between midnight after Sunday's Hungarian grand prix, and the resumption of action at of September's race at Spa five weeks later, all the teams will lock their doors for a full 14-day period.

The cost-cutting measure has been in place for the past few seasons.

"As it happens we're also shutting down our automotive production at the same time, even though we don't need to do it," McLaren team boss Martin Whitmarsh is quoted by Press Association.

"And we're not doing it to avoid any aspersions being cast by other teams. It is a separate company."

Whitmarsh said he is not sure if rival Ferrari is also closing its separate road car plant.
