TECH TALK: What upgrades have Ferrari brought to Spain?

The focus of this week's Tech Talk is on Ferrari's upgrades for the Spanish Grand Prix, as tech expert Sam Collins looks at key modifications to the airbox, sidepods and more.

"When I say it's very heavily modified, I really do mean it," says our host as he looks at the new bits on the SF21. He starts with small adaptions to the roll hoop of the car to increase cooling – a major upgrade.

And the sidepods have been reshaped too, along with new elements on the rear of the floor as they – along with their rivals – wrestle with the new-for-2021 aerodynamic regulations.
