Since Liberty Media have stepped in, they are working hard with Ross Brawn to deliver the world class, on track action that we have all craved for so long. A press statement was released yesterday analysing and outlining the changes to the rules which every F1 team will have to follow. I think you're going to like them, but have a read and let me know in the comments what you think!

- A simplified front wing with standardised endplates, tweaked dimensions and no upper flaps. This will encourage aerodynamicists to direct more of the flow to the underbody (where it is less sensitive to the disturbed wake of the car in front) than the outer body

- The deletion of the upper flaps at the outer ends of the wing will make it impossible to create the vortices that are generated by the current, highly complex endplates to enhance the outer-body aerodynamics. This will further encourage the so-called ‘inwash’ aero philosophy of directing airflow to the underbody, rather than the current emphasis on ‘outwash,’ which is highly sensitive to the air from the car ahead and therefore makes it harder for cars to follow one another closely

- Tweaks to the front wing’s dimensions and the limiting of under-wing strakes to two each side to further discourage outwash aerodynamics

- Winglets mounted on the brake ducts currently play a part in directing the flow to the outer part of the body. These are banned from 2019, as are blown axles, which currently use air directed out of the centre of the wheel at high speed to energise the flow down the outer surfaces of the bodywork further back

- Barge boards are lowered by 150mm (to make them less powerful in directing the airflow) and moved forwards by 100mm to make them less sensitive to the airflow being disturbed from the car in front

- The rear wing endplates will no longer be permitted to have horizontal gills. These equalize the pressure between the inner and outer faces of the endplate to give a faster flow over the top of the wing for more downforce, but they introduce an extra disturbance to the wake, which worsens the performance of the car behind

- The DRS opening will be increased from 65mm to 85mm. Together with an increase in width and height of the wing, this will make the DRS around 25-30% more powerful so as to allow it to be effective on those circuits with too short a straight for the current system. The FIA will also review the length of DRS zones at every circuit in order to maximise the effect of the changes

- The increased height of the wing will take the 'rooster tail' wake coming off the back of it higher into the air than currently. More of the energy from that wake will be diffused into the free air around it before it returns to the level where it will be affecting the following car.

So from the sounds of it, we'll be seeing chunkier, meaner looking F1 cars than ever before, but will this bring the pack together? What do you think of the changes and are you excited to see this implemented next season? Let me know in the comments below!

  • i like the general direction that this is headed. However i think engines should be simplified and made cheaper as well. Otherwise you just will haver Ferarris and Mercedes blasting past everyone on the straights and not having to riks overtakes in the corners where all the exiting tangles ocurr

  • eliminate all the garbage add-ons behind the front wheels and cooling intake. No more barge boards or knife edge slats etc, clean this up and eliminate all the noise there.

  • What if they made DRS available any time the driver wants, so long as he is within 1 second of the driver in front? Leave it up to the driver to decide between straight line speed and handling wherever they are on the track. They're the best drivers in the world, no? Let them be brave when they want to be.

    • That is a very interesting suggestion and I definitely think that it could be a good one to debate.

    • And for that matter, why not expand it to 1.5 seconds?

  • Isn’t it Wednesday today? (Good article though I really hope these changes help!)

  • I also want to see backmarker cars be able to drop banana peels and various types of non-lethal explosives onto the track surface just like any of the Mario Kart games. I don't think that the current crop of F1 drivers are enraged enough by their jobs...and Mario Kart would go far to re-introduce rage back into the sport.
