The Autosport Podcast will bring you coverage of Formula 1 testing at the end of every day of track action. On today's podcast we're looking at the first day of testing (officially a shakedown) and how any fears about early reliability were quickly dispelled. Eight teams achieved over 100 laps as they executed their individual run plans with little drama and no red flags to interrupt sessions.

Martyn Lee is joined by Jake Boxall-Legge (Technical Editor, Autosport) and Haydn Cobb (Autosport.com Editor) to talk about what it was like trackside, and also analyse some of the technical aspects of the Red Bull RB18 which made it's first real appearance today.
