Five interesting Spanish GP F1 updates you may have missed

But while almost all of the attention on car changes has been on Aston Martin amid a copy cat row with Red Bull, there have been plenty of other noteworthy ideas that have emerged up and down the pitlane.

Here we take a look at the most interesting upgrades that have been spotted so far.

Red Bull has a revised front wing, enabling it to generate more load and balance it against the high downforce rear wing it has mounted on the RB18.

However, in terms of non-circuit specific updates, we have to look at its floor and more specifically the region where the sidepods undercut meets with the widest section of the sidepod bodywork for something a bit more detailed.

It’s here, which the team noted in the pre-event automobile notes, that it has added a teardrop shaped blister in order to influence the airflow’s direction and improve the total pressure on the upper surface of the floor (red arrow).

However, what’s also new but wasn’t expressly talked about, is an upturned lip now applied to the section of floor before the cutout (blue arrow) that will defend against the airflow spilling off the surface.

These two small adjustments have been made in combination in order to better manage the airflow’s route and pressure distribution in that region, not only to improve performance locally but also up and downstream of the section.

Ferrari has a new, higher downforce, rear wing this weekend, which the team tested in advance at Monza during a filming day. It features a revised spoon shaping to the mainplane and the upper flap has a deeper chord length in the outboard section.

Ferrari first tested a new specification floor and diffuser in Australia but, having only one manufactured at that point and perhaps not giving the instantaneous uplift in performance it expected, it wasn’t raced.

In order to unlock the performance merits of that floor and…
