TECH TUESDAY: How Ferrari cleverly re-engineered their mediocre 2020 automobile into the a lot more rapidly SF21

Mark Hughes appears to be at how Ferrari upgraded their 2021 Ferrari SF21 to boost

Mark Hughes appears to be at how Ferrari upgraded their 2021 Ferrari SF21 to boost it considerably beyond its 2020 predecessor – the SF1000 – soon after a Hungarian Grand Prix in which Carlos Sainz scored a podium for the group. Giorgio Piola presents complex illustrations.

Ferrari shed out on a actual chance of staying in contention for victory in Hungary, supplied the to start with corner mayhem which took a Mercedes, two Crimson Bulls and a McLaren out of contention and led indirectly to Lewis Hamilton falling to the back again.

On a day in which Charles Leclerc was also taken out and the get was fought out concerning an Alpine and an Aston Martin, Ferrari could truly feel frustrated that their one remaining car of Carlos Sainz was bottled up powering the 3rd-area Williams of Nicholas Latifi for considerably of the 1st stint. Were being it not for that, Ferrari may have experienced a victory to incorporate to their 2021 brace of pole positions, underlining their big development given that last 12 months and the usefulness of the SF21’s update from the preceding SF1000.

Far more particulars are now recognized about the automobile than when it was released at the commencing of the time and it is very clear just how considerably innovation was integrated into the up grade even with the homologation constraints, which minimal enhancement from previous season to this, by a token process.

That token process limited the range of key variations which could be manufactured and in the situation of Ferrari properly gave them the choice of making key structural modifications at the front of the car or truck or the rear.

Preferably they would have adjusted equally, as their rear suspension and aerodynamics and their nose form aerodynamics both had a ton of scope for enhancement. But the token system did not allow for that, so Ferrari concentrated on the place it felt the greater limitation was – the rear finish.

Important to this was a new gearbox casing, sweeping further back than ahead of – and also tilted upwards. The extended casing permitted the rear suspension to be swept back again in a related way to that of the 2020 Mercedes, generating more place about the diffuser for aerodynamic exploitation.

The token process intended Ferrari could not mount the suspension into the crash framework – the way Mercedes experienced accomplished it – but as an alternative they stretched the gearbox back again (underneath) considerably more to attain the exact outcome.

The enter close of the gearbox can be observed peeking from the carbon-fibre sheath at the entrance. Its slight upwards tilt has allowed the ground to be elevated far more (yellow strains), developing far more airflow quantity all-around the diffuser. This has raised the height of the differential (yellow cross marks the driveshaft top at the diff), necessitating heavily-angled driveshafts.

Tilting the gearbox a little bit upwards has moved the differential up a very important pair of centimetres and thus developed deeper aspect channels in that similar aerodynamically impressive region around the diffuser.

This raised differential is expected to be quite substantially a regular aspect of all the 2022 cars mainly because of the arrangement of the effective floor outcome venturis stretching from the front of the flooring. Aerodynamicists will be keen to maximise the ramp angle of individuals venturis and a raised differential will aid this, even although it does enhance the centre of gravity height.

At the entrance, Ferrari have been limited by their unfashionably huge nose. Mercedes switched to a slender nose in 2017, Purple Bull making a identical change in 2020. The slim nose will allow the cape beneath the nose to start out turning the airflow in the direction of the bargeboards substantially earlier. The earlier it can be turned, the much less it will detach and the more precisely it can be guided towards the several vanes which accelerate the air.


The Ferrari has a distinctive double cape arrangement beneath the nose, the upper cape turning the air toward the bargeboards, the reduce one (highlighted in yellow) encouraging speed up the move instantly to the underfloor.

With the wide nose there tends to be a ‘dead zone’ beneath the place the air is not staying energised. Ferrari have tried to minimise this by a 2nd smaller cape beneath the principal a person (earlier mentioned), which seems to be channelling the air straight to the underfloor with increased pace. The quicker the airflow beneath the floor, the greater the downforce.

Ferrari could have been confined in how significantly they could re-engineer their mediocre 2020 automobile, but have proven fantastic ingenuity inside those limits. Which is a favourable sign for 2022, when they will bring out an all-new motor vehicle for the revamped regulations coming in upcoming calendar year.
