The main topic for this episode of The F1 Tech Show was an obvious choice, after Red Bull admitted in Austin that it has a device that can adjust the height of the ‘bib’ at the front of the floor but denying that it was ever – or could ever have been – used to make changes during parc ferme.

Edd Straw is joined by former F1 technical director Gary Anderson to explain why bib height is so important, how the adjuster tool works, and why Red Bull's rivals are annoyed.

Also on the show, Gary gives his opinion on Mercedes' US Grand Prix struggles, after its latest upgrade failed to deliver consistent results, plus he answers another handful of questions from listeners, including one sent in by a NASA systems engineer!
