Technically Formula 1 - Malaysian Gran Prix

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 pre-season tests and the Australian Gran Prix.

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

Red Bull RB10

RB10 nose detail.

Note the strakes on the underside of the Red Bull's front wing to keep the air in line and support a low-downforce area underneath the wing.

Also note the driver-cooling inlet on the nose tip, and the bubble-shaped bodywork on the underside of the nose.

Mercedes WO5 Front wing, note the vortex generators on the second tier of the mainplane sit ahead of the strakes behind the wing. These disturb the airflow increasing the strakes efficiency

It looks as though Mercedes have newly shaped sidepods this week in Malaysia. The sidepod airflow conditioners are modified, but retain a similar shape from 2 weeks ago.

Note the slots on the @MercedesAMGF1 bargebaord and the vane next to the T-Tray

@ScarbsF1

Technically Formula 1 - Malaysian Gran Prix

Note the U-shaped floor leading to the rear diffuser. I assume that this is a way to vent hot air and increase the speed of the air flowing out of the diffuser though the flow of hot air's use.

Like most teams the @MercedesAMGF1 wheel is polysil coated & knurled to absorb heat (not reflect as I said yesterday)

Note the NACA ducts on the F14T's nose, as well as the winglet on top of the airbox.

Lotus sporting new Proton sponsorship.

Technically Formula 1 - Malaysian Gran Prix

Lotus engineer cutting something. Looks like some sort of duct.

Technically Formula 1 - Malaysian Gran Prix

Also note Lotus' interpretation of the ductless brake duct. Most traditional brake ducts have a vertical sheet of carbon separating the tire sidewall and the brake duct. The E22 takes this sheet of carbon and molds it into a duct shape, using the tire sidewall as part of the duct.

Technically Formula 1 - Malaysian Gran Prix

Another view.

The E22's sidepods don't look traditional. I am assuming that the radidator(s) are packed inside that carbon box.

Lotus the box with the blue cables and bundle of clear tubes connected to it is for air pressure sensors on the floor

McLaren MP4-29

Technically Formula 1 - Malaysian Gran Prix

McLaren have a new nose!

Technically Formula 1 - Malaysian Gran Prix

This iteration is meant to allow more air underneath the nose and flow back around toward the rear diffuser.

Technically Formula 1 - Malaysian Gran Prix

More nasal action.

Note the elongated pylon supports for the front wing.

Note the side crash structures, one above and one belwow; these are now mandated parts by the FIA instead of the teams running a crash test with a team-designed part, like the nose is now.

More McLaren note the unusual radiator angle and the duct feeding the outlet near the cockpit
