Formula 1 2019 Aero changes
This week significant 2019 Aero changes were announced. These modifications to the Aerodynamic regulations were voted by the teams, the FIA and the Commercial Rights Holder and passed the required percentage of the vote. In response to a somewhat processional Australian GP, there was subsequent discussion between Liberty Media and the FIA, with the hope of fast tracking some proposed changes to the cars for 2021 to next season, improving the ability of drivers to race closely and overtake. The regulation changes are as follows:

Simplified front wing, with a larger span and low outwash potential
Simplified front brake duct with no winglets
Wider and deeper rear wing

Front Wing
The front wing is one of the most critical Aerodynamic devices on the cars, not only producing front downforce, but also determining the quality of flow to the rear of the car, notably by attempting to minimise the disturbance created by the front tyre. The first 2019 Aero change is a proposal to make the wing wider in span, perhaps to the extent that it will be as large as the overall car width, at 2000 mm (current width ? 1800 mm). This will increase the downforce potential of the cars at the front, which could be balanced by greater rear load, but will increase structural considerations for Engineers in the teams.
Most critically, however, the ability to create an outwash effect from the front wing will be diminished, as ...
