No airbox on Mercedes' revised 2010 car

Stephan Heublein


One of the innovations on the Mercedes car for the Spanish grand prix is the abolishment of the traditional 'airbox'.

The airbox - an inlet for the normally-aspirated engines - has traditionally been part of the roll-hoop structure immediately behind and above the drivers' head.

But the rollover structure of the revised W01 is now sharp as a knife, with air to now be fed to the 2.4 litre V8 engine via two symmetrical inlets on either side of the engine cover.

Also spotted in the Barcelona pitlane on Thursday was Christian Klien, having his moulded seat and settings fitted to the HRT car usually belonging to Karun Chandhok.
