Technical innovation is what makes Formula 1 so different from any other form of racing. The on track action is as much played out by the engineers and aerodynamicists as it is the drivers. We are here to admire, study, and discuss this beauty that exists on the ragged edge of what we think is possible, or at least what we thought was possible.

For more technical intrigue, be sure to check out this year's previous testing days.

Discussions and questions are welcomed and encouraged in the comments section below.

Testing Day 12 - Bahrain

Red Bull RB10

Red Bull's Keel nose and its "U" shape 'driver cooling' slot


The RB10's front wing sports several slots on the endplate (just below the 'Total' logo) that filter air from the outside of the wing to the underside; this is an attempt, working with the rest of the front wing elements, to manage the disruption of the air flowing around the tires.

Red Bull flow-vis testing tire wake off their RB10.

Red Bull go Williams-style with the arched mounting for the monkey seat


@RedBullRacing have added a low-line Y100/Monkey Seat to the RB10 today,just above the crash structure


Mercedes W05

Mercedes look to be flow-vis testing the air flowing just beneath the nose. The teams use this florescent paint to see where how the air is moving around their chassis' bodywork.

@MercedesAMGF1 WO5 - New Roll hoop cooling inlet (likely for oil cooler above the gearbox) & return to shark fin


The lights that you see on top of the airbox inlet are to show the engineers/pitlane workers/marshalls if the electrical systems are safe, and the car is therefore safe to approach. Green means that the systems are okay, and red means that there is a problem.

@MercedesAMGF1 WO5 - Flo-Viz applied to centre of FW mainplane, under nose, chassis & lower sidepod/floor #TechF1


Ferrari F14T

Ferrari have a side facing camera looking at any potential front wing flex


Ferrari flow-vis testing the rear of their 2014 F14T chassis.

@InsideFerrari using Flo-Viz on the rear wing likely assessing the impact of using the larger cooling outlet #TechF1


F14T rear end detail.

Ferrari also ave their revised engine cover, note the run of louvers on its spine to cool the [turbo]


Lotus E22

E22 front end detail. The nose on the left (the legal portion of the nose) is slightly longer than the nose on the right. Lotus are not going to switch the two depending on the clock-wise-ness of the track. The left one will always be longer.

strangely Lotus have been runnign these blanking pads over the rear tyre deck area, I dont know why?


McLaren MP4-29

MP4-29 front end detail. The McLaren's airbox inlet is split into two. I cannot say for certain where each section is leading the air, but more than likely one is feeding the engine or electrical systems, and the other is feeding the turbo.

McLaren are pitot-tube testing using a long horizontal array (seen on your right side of the chassis between the left-front tire and the sidepod inlet).

Force India VJM07

Force India front-end detail.

Force India, note the sloped end of the raised chassis, FIF1 step their chassis unlike STR for a small aero benefit


Sauber C33

Sauber C33 front-end detail.

Toro Rosso STR9

Scuderia Toro Rosso front-end detail.

Toro Rosso front bulkhead, like McLaren slope the entire raised chassis to meet the new 525mm height of the bulkhead


Williams FW36

Williams retain their trademark 3D printed 'driver cooling' slot


That Senna sticker has graced every Williams chassis since Ayrton's tragic death.

Marussia MR03

The marussia is a neat car, note they have almost the same Keel nose as Red Bull


Marussia have a similar rear wing mount to @McLarenF1 , altho Mac's has a hidden aero [advantage]
