The RB5 is one of the most innovative and radical cars of 2009. The chassis is V-shaped (1) on top, improving the management of airflow towards the rear of the car. Both the chassis and suspension are higher than on the previous RB4, as is the position of the driver's feet. The two central pillars (2) connecting the nose to the front wing are straight and close together, while the wing's main plane is intricately shaped where it joins the endplate (3) to direct airflow under the wing. Both the main plane and the upper flap are slotted (4). Also note the ballast compartment (5) in the endplate. Source : www.f1.com
The RB5 is almost certainly the most innovative and extreme car on the 2009 grid. Its chassis is very high at the front, with its unique U-shape meaning the front suspension's lower wishbones share almost a single pickup point, with just a small separation in between (red arrow). This solution has the benefit of allowing a large volume of air to pass under the chassis and feed the (conventional) rear diffuser. Source : www.f1.com

The RB5 brings pull-rod rear suspension back to Formula One for the first time in over 20 years. With the diffuser moving rearwards under the revised 2009 regulations, the pull-rod layout (2) - where the suspension rockers are pulled rather than pushed by the rod - allows for cleaner aero packaging (see inset for more common push-rod set-up). The pull-rod suspension is lighter and, along with a gearbox that is now 15cm lower, helps to lower the car's centre of gravity and improve handling. The top wishbone is a single piece and is attached very high at the rear of the car (1), forming a wing-like section that works together with the lower section of the rear wing. Also note the very low and rearward positioning of the exhausts (3), which exit just under the front arm of the rear wishbone, and the lack of a central pillar to the rear wing, which is instead mounted via the wing's two large endplates, which attach directly to the diffuser. source : www.f1.com
B for Adrian Newey, Geoff Willis team for designing a beautiful car, that has moved up the grid considerably from 7th overall last year to currently 2nd. However, it is not yet capable of matching the pace of Brawn. I believe, most of that shortfall is with the Renault engine and the RB5 chassis on its own is capable of winning races if it had a stronger engine.
Introduced in Malaysia and retained for China is this hole in the floor's footplate in front of the rear tyres. Its purpose is to create a vortex that improves the quality of the airflow directed into the side channels of the rear diffuser, thus boosting downforce.(From http://www.f1.com)
Great great shots! That RB5 is sooo sweet! Have you noticed the filup/diffusers that were added to the sides of the floor along the sidepod area a few races a go? I would like to see more about those .. I'm surprised no one has talked them up. It looks to be a sweet detail.
