F1 returns this week with pre-season testing, meaning cars will be back on track for the first time since 2023.
It has been almost three months since the Abu Dhabi Grand Prix and a lot has happened in the off-season.
Williams revealed it has kept Logan Sargeant for 2024, Lando Norris and Charles Leclerc both signed long-term contracts with their teams, while Lewis Hamilton announced a shock move to Ferrari for the 2025 season - not to forget the re-branding that’s happened at RB and Sauber.
Car launch season also took place, where each team revealed the look of its 2024 challenger with constructors like Sauber and RB overhauling their colour scheme.
Another big talking point of car launches though was push and pull-rods - discussing which team had adopted what type of suspension.
So, what is the difference between them both and why are they so important?
