McLaren introduced what more or less amounts to a 'B version' of the MP4-24 in Germany, with a new front wing, new side pods, new engine cover, new floor (the V-shaped cut-in in front of the rear tyres has gone) and a new rear diffuser, shown here, with a much wider, asymmetric central channel. The car improved by around eight-tenths of a second with the new package - so far only available to Lewis Hamilton. Team mate Heikki Kovalainen has just the new front wing at the Nurburgring.
Ferrari F60 - modified rear diffuser
Ahead of Friday practice in Germany, Ferrari revised the F60's rear diffuser. Felipe Massa ran it in the morning session, both drivers in the afternoon's. The previous version, shown in the left half of this drawing (1), had just one vertical fence. The new version, shown on the right (2), now has three fences in order to improve the air extraction from the side channels.
