' '

The winds of change have started to blow on Formula 1, beginning with a set of rule tweaks this year that should prefigure the sport's major regulation overhaul in 2021. Ahead of pre-season testing which kicks off on February 18, F1i has compiled a summary of what you need to know about the technical and sporting imperatives that teams will be contending with in 2019.

The times, they are a changin' for F1 this year, but it's anybody's guess if the alterations to the sport's technical rules will upgrade the show.

Liberty Media and the FIA, under the guidance and astute expertise of F1's managing director of motorsport Ross Brawn, have centered their transformative efforts around aerodynamics, front and rear, in a bid to improve overtaking, and thus the racing.

While the aero tweaks have garnered most of the talk, tyres and various other technical and sporting elements were also put under review and subsequently adjusted, amended or changed.
