CHANGES TO THE CIRCUIT SINCE 2010

Lap record: 1:24.125 (Michael Schumacher, Ferrari, 2004)
[842] 27 March 2011 - Red Bull RB7 - revised blown exhausts
 
For Australia Red Bull have slightly modified their blown exhausts, with a small extension on the flat pipe blowing just in front of the rear tyres (main drawing - previous design inset). The underbody has been cut slightly differently (highlighted in yellow) in order to divert more airflow under the side channels of the rear diffuser.
[843] 27 March 2011 - Ferrari 150° Italia - pre-season evolution
 
After a hectic winter test programme, Ferrari have introduced the latest version of their 2011 car (top drawing - launch version below) for the Australian Grand Prix. There are new front wing supports (1), featuring very wide pillars, in order to better channel the air under the car, whilst the revised front wing has noticeably different endplates (2). There is a much bigger undercut (3) at the front of the sidepods to feed more air to the back of the car. At the car's midpoint there are new vertical splitters (4), whilst narrower bodywork is highlighted by the larger portion of the black, heat-resistant material (5). There's a revised exhaust (6), inspired by the one featured on the Red Bull, which features longer pipes blowing towards the side diffusers (7). Finally at the back there's a new version of the diffuser designed to complement the revised exhausts (8).
[844] 27 March 2011 - Williams FW33 - innovative gearbox layout
 
Arguably the most innovative solution on the 2011 Williams is the layout of its new gearbox, which has been designed to match the car's new rear aero package, in light of this year's ban on the double diffusers. The gearbox's vertical dimensions have been dramatically cut and the differential has been lowered (see yellow highlighted area). This forced the team, after a great deal of research, to choose an extreme driveshaft angle of nearly 16 degrees, which is very unusual, as is attaching the suspension's top wishbone to the rear wing support (red arrow). This solution could be very advantageous, although there are still limits, mostly imposed by the dimensions of the car's engine cover.
[845] 27 March 2011 - McLaren MP4-26 - revised exhaust layout
Both Ferrari and McLaren have followed Red Bull in the layout of their exhaust systems, but while the Scuderia had theirs on the car at the last Barcelona test, complete with new sidepods and aero package, the Woking team only prepared their new pieces in time for Australian Grand Prix. The exhausts are longer and blow into a cut-out outside section of the diffuser (as on the Red Bull). Another change is that the diffuser is now made in titanium (highly resistant to heat), using a quick prototyping technique.
