F1 tech: The 2021 parts teams are already testing

Daniel Ricciardo was on hand to complete the tests for the team, a sign perhaps of the regard that it holds for his feedback, given the Australian will be moving on to McLaren next season.

The floor used by Renault during these tests is what the FIA intended with the regulation change - a simple diagonal cut-out ahead of the rear tyre with no fully enclosed holes beside the floor’s edge.

This is paired with changes regarding the height of the vertical strakes housed within the diffuser, which will be 50mm shorter in 2021. The width of the winglets housed on the bottom half of the rear brake duct will need to be 40mm narrower.

Over at Mercedes, the team spent more time evaluating the 2021 tyres than some of its rivals, opting to sacrifice setup time for the weekend in favour of understanding the new tyre.

It also added a polystyrene covering to the end of its upper wishbone whilst testing the 2021 specification tyres.

Their upright extension places the wishbone in close proximity to the tyre’s sidewall, so the polystyrene not only offered some limited protection it would also be shaved away if they came into contact.

This is a tactic we’ve seen from teams down the years when trying to place other aerodynamic surfaces within close proximity to the tyre.
