From testing in 2022 until May's Monaco Grand Prix, Mercedes pioneered the use of its size-zero sidepod car architecture. It then switched the W14 to run a downwash philosophy, as favoured by Red Bull, but with the addition of a 'waterslide' akin to that of McLaren and Aston Martin.
With the upgrade fitted, Hamilton led a 2-3 result in the following Spanish GP. But Mercedes had also enjoyed a Barcelona boost in 2022 when George Russell held on to third place.
