Welcome to OppositeLock's own Formula 1 open technical discussion! The one thing that separates Formula 1 from any other motorsport is the absurd level of engineering and aerodynamic advancement that the teams push on each other, and we are here to appreciate, discuss, and revel in the beauty of design on the current limits of speed.
Open discussions in the comments section are welcomed and promoted. I will post a few pictures that I've found interesting on a particular race weekend, and hopefully we'll get some great discussions stirring!
Red Bull
Red Bull are one of the few teams not to implement a 'ductless' front brake duct, instead choosing to stick with the classic idea calculate that, for them, the benefits of this duct out weight the costs of a 'ductless' duct.
A blown front wheel duct can also be seen on the RB9 that vents air from inside the wheel to the outside in an attempt to lower the pressure on the outside of the wheel and reduce drag.
Ferrari
A new extension carrying new winglets and vanes can be found sticking out of the floor near the front of the sidepod. These could help control the turbulence from the tires, control the air flowing round the sidepods to be better dealt with at the rear of the car, or both; I'm not certain.
Pictured filling the gap between the rear wing and the beam wing is what is commonly called either the 'Y-75 Winglet' or 'Monkey Seat', the latter being more imaginatively satisfying. In 2014 that beam wing that stretches the width of the rear wing supports will be illegal, and thus none of the teams will run it again.
There seems to be a new bridge of carbon on the underside of the diffuser, square in the middle that covers the starter hole. This bridge of carbon looks to be helped along by another piece of carbon that connects the diffuser with the rear crash structure.
Mercedes
Mercedes' version of the Coanda effect exhaust body work that can be seen with extra slotted vents to rid the inside of the W04 chassis of heat.
Williams
Williams front wing cascade element detail.
Williams Pitot-tube testing the rear of their car. The chassis also seems to be sporting an interestingly shaped rear brake duct.
Tight body work packaging can be found surrounding the gearbox of the Williams chassis.
Sauber
