The RB20 has earned comparability to the Mercedes W14 from 2023 courtesy of latest engine cowl bodywork that includes a excessive waistline, with full-length gulleys working from the sting of the halo.
Purple Bull has additionally moved away from an underbite-lookalike sidepod inlet, a function now extensively utilized by different groups, to an overbite the place the highest floor extends past the principle consumption.
However Motorsport.com understands that this design is because of stay just for the new circumstances of pre-season testing and the opening rounds in Bahrain, Australia and Saudi Arabia.
As F1 then strikes to Japan in early April, the place temperatures will drop and cooling shall be much less marginal, the RB20 shall be upgraded to a design paying homage to the Mercedes size-zero sidepod. This was an idea that Mercedes struggled to unlock all through 2022 and 2023.
Mercedes’ principle was that by shrinking the bodywork to extend the floor space of the prepotent ground for the brand new floor impact period, higher downforce could possibly be achieved.
Nonetheless, whereas these robust numbers have been simulated within the wind tunnel with excellent management circumstances, the automotive was moved exterior of its slender working window by the bumps within the floor at real-world circuits.
Mercedes finally deserted that format for the 2023 Monaco Grand Prix, the place the workforce shifted to extra typical downwash sidepods, as pioneered most notably by Purple Bull.
Purple Bull ought to be capable to facilitate its personal transfer to a so-called ‘zeropod’ because the launch-spec RB20 seems to have extra compact vertical sidepod radiator inlets to permit for tighter bodywork.

The workforce could make additional use of a trick it deployed in 2023 to partially offset the Aerodynamic Testing Restrictions which restrict wind tunnel runs and CFD simulations – with Purple Bull probably the most affected final 12 months as a result of its lead within the constructors’ championship along with an additional 10% minimize as punishment for exceeding the 2021 price cap.
The Aerodynamic Testing Restrictions enable exceptions for “wind tunnel testing solely for the event of energy unit warmth exchangers that reject warmth to air, or the working of the facility unit from a boundary commencing on the energy unit air consumption ducts”.
As per final season, and once more with a shift to Mercedes-style zero-pods, Purple Bull has positioned an emphasis on upgrades that lean in direction of cooling. The repackaging of the inner parts falls exterior of the ATR to then allow the workforce to spend much less of its allowance refining the exterior bodywork.
Talking on the launch of the RB20, Purple Bull workforce principal Christian Horner mentioned: “Logically, there’s going to be convergence with steady laws. We will see different automobiles have taken an affect from the RB19.
“So, I feel the workforce has completed an exquisite job on RB20. They have not sat on their laurels, and you’ll see that they’ve pushed the boundaries with the automotive…
“You’re continuously trying to evolve. When you have a look at the eye to element on the automotive, there’s some actually beautiful element. There’s been no complacency, they’ve continued to evolve and proceed to push the boundaries.
“There’s nice innovation on the automotive as effectively that little question shall be scrutinised over the approaching couple of weeks, however I feel creativity has been robust within the workforce… It’s not a conservative evolution.”
Requested about shifting in direction of a Mercedes-style engine cowl, Horner replied: “It isn’t tactical. It is based mostly on efficiency and what we’re seeing by way of our simulation instruments.”
