Technically Formula 1 - Malaysian Gran Prix

Illustration for article titled 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.

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.

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.

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

Illustration for article titled 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.
