Technically Formula 1 - Spanish Gran Prix

(Updated Quali) 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 Gran Prix.

This post will be updated as the weekend progresses. Discussions and questions are welcomed and encouraged in the comments section below.

F14T blown wheel nut detail. The ginormous (that's a technical term...) duct on the left funnels air to both the brake itself and straight out for "blowing." Note the split carbon section inside the duct.

Technically Formula 1 - Spanish Gran Prix

Ferrari are running a new single pylon rear wing support on the centerline, contrasted to the old version as seen in the previous picture with two supports.

Less obstruction of the air = Less drag (at least in this case).

Technically Formula 1 - Spanish Gran Prix

The new pylon is an inverted Y shape that splits just before the exhaust and connects to the rear crash structure.

Ferrari are also running a Y75 winglet this weekend, one of the last teams to implement one. The Y75 winglet (often called a monkey seat) creates a low pressure underneath the winglet; this low pressure then pulls the exhaust gasses upwards to help connect the upwash of the rear wing and the rear diffuser, effectively creating a single entity of upwash.

Lotus E22

It looks like Lotus are continuing to run their nose wing in the center of their twin tusk design, seen being held up by 5 pylons in the center.

Y75 winglet detail. Note it's asymmetric mounting due to the centerline rear wing pylon existing skewed to the left side of the E22.

Technically Formula 1 - Spanish Gran Prix

E22 rear end detail.

Note the horizontal (and curved upwards) slots on the rear wing endplates.

Also note the padding between the exhaust outlet and the centerline rear wing support; this is probably for heat protection of the carbon support.

Lotus also running their E22 without the Monkey Seat to compare its effects, but are in fact running the Y75 winglet for the race.

McLaren have opened up some bodywork trailing a suspension component; new for this weekend.

Technically Formula 1 - Spanish Gran Prix

MP4-29 rear wing detail. Note how the centerline rear wing pylon curves around the exhaust in a particular way that virtually extends it as part of the Y75 wiglet; waiting for more teams to jump on this bandwagon.

Wait... what's that on the Caterham? Let's move in closer...

Technically Formula 1 - Spanish Gran Prix

A second winglet just below the exhaust?! Is that legal?

Also note the winglets preceding the bodywork that connects the rear crash structure to the diffuser; for most teams this is just a single sheet of carbon (the most rearwards on the Caterham).

Technically Formula 1 - Spanish Gran Prix

Something innovative from the Caterham outfit; didn't see that coming...
