Mercedes upgrades

Small flicks on the front wing

The flicks help♋ focus t꧒he vorticity shed from the wing tip vorticity, improving performance over a wider range of front ride heights.

Lifted tips on the rear wing

Offloading the tip of the wing has shed drag efficiently - this is important for Bahrain and a number of circuits in the early part of the season

Re-profiled underside of nose

Increased front wing local load and improved conditioning of the flow under the chassis and downstream - notably to the underfloor and fences.

Small floor changes

Increased forward floor load, and cleanerꦍ rear floor edge wing vortex - which in turns increases diffuser load.

Narrower sidepod inlet

Improved flow internal🎀ly to the radiator resulting in more efficient engine cooling; also improved flow to the rear floor edge, providing more rear downforce.

Change in front suspension height

Dropping the track rod has improved the effectiveness of the lower wishbone to turn (downwash) the flow from th𝓀e front wing for the benefit of the underfꦰloor.

Red Bull upgrades

Floor Edge

It is not a change the team chose to pursue, nor was 🍨it benefic꧂ial to car performance so the resulting geometry was aimed at minimising the incurred loss. 

Front Wing

Given th🦩e opportunity to evolve the wing, more load was derived overall without increasing the downstream consequences.

Coke/Engine Cover

🅘Given the opportunity to optimise the cooling from the data garnered in 2022, the layout has chang🦋ed subtly and the topbody exit duct has changed to reduce consequences downstream on the exit.

Floor Body

The floor is designed to adapt to the new regulations, add downforce to the car at all carꦅ speeds and minimize porpoisi𒈔ng

Front Corner

The front brake duct is designed to provide the necessary level of brake disc and caliper ♏cooling for high braking demand circuits, whilst minimizing the aerodynamic effect on the car. 

Sidepod Inlet

Coke/Engine Cover

The bodywork is designed to improve the flow to the rear of t🌊he♛ car and increase downforce. A new car design for 2023 has allowed us to package the sidepods in such a way as to allow for a larger undercut

Cooling Louvres

The design, location, and size of the cooling louvers can affect the aerodynamic performance at the rear of 💖the car. The design improves car efficiency when adjusting the cooling level for higher temperature ambient conditions.

Beam Wing

The beam wing design improves efficiency and downforce at the rear🐻 of the car, it has different span-wise loading to last years design

Rear Corner

The rear brake duct is designed to provide the necessary level of brake disc and caliper cooling for high braking demand 🧜circuits, whilst minimizing the aerodynamic effect on the car

Alfa Romeo upgrades

Front Suspension

The changes to the 🐷chassis and front suspension covers help improve airflow traveling down the car and into the sidepod. This should help increase the overall aero efficiency

Floor Body

The new fl📖oor has been ಞdesigned to improve overall downforce while minimising the losses caused by the rule changes.

Halo

The changes aim to reduce losse♌s from the HALO itself whilst also managing other losses created📖 by the cockpit opening

Sidepod Inlet 

The larger undercut below the cooling inlet allows more, high energy, flow to the back of the ca🎐r to work with the floor edge

Coke/Engine Cover

The new bodywork is primarily to package the 🉐new central cooler and reduced side co♛olers. The new design improves flow to the rear of the car

Rear Corner

Haas upgrades

Nose

The criteria that has been followed in the nosecone shape optimization is to improve t𝓀he pressure distribution behind the Front Wing and improve the inlet air mass flow toward the front floor. 

Front Wing

The improvement of the global efficiency of the car imp🎐ose a very slim volume of the components a wing is composed, in this way we can get advantage by the phenomena connected to the wheel turbule⛦nce structure. 

Front Wing Endplate

The interaction of the pr🎐essure field generated by the front wing endplate zone and the wheel one, has generated a robust wake with advantages seen even at the rear body too.

Front Suspension

Has been optimised the aerodyn𝓀amic strucꦺture of the suspension legs with advantages at the correct working of the front wing and the improvement of the impact of the flow towards the front part of the floor. 

Floor Fences

Ourꦰ research direction has been to maximise the combination of surface contraction imposed by the regulation in this area with the effect of washing out used🦩 even when regulation was allowing the bargeboard.

Floor Body 

A correct and balanced contraction and expansion has resulted to be as one of the key rule ♛to provide efficiency at the entire car aerodynamic package𝐆.

Front Corner

In addition to the cooling optimization a deep attention has been taken for the influence ꦗthat the front corner bodywork have on the front wing tip aerodynamic and the wake generated beh𝓀ind the wheel.

Cooling Louvres

With several loop of simulation and correlation work the complex package composed by several elements dedicated to th🐼e heat transfer has been investigated with the aim to improve cooling mana🍒gement.

Diffuser

No elements of the diffuser or its surfaces has been maintained from the 2022 car. Beam wing and diffuser trailing edge are developed together to gather the maximum expansion at th🤪e rear of the car. 

Rear Suspension

The structural and kinematic constraints, oblige not to push over some limit the aerodynamic requirement at the car rearend. Nevertheless a new lay out has been found t𒀰hat represent a significant step forward in the car performance respect the previous model

AlphaTauri upgrades

Nose

The narrower and more integrated nose is used to reduce the loss from th🎀e nose and inboard sections of the FW that eventually pass under the floor and hamper its performance. The s🌳ectional shaping is designed to enhance the pressure field created by the front suspension

Front Wing

The shorter inboard sections work in conjunction with the nose surface to better condition the flow to the floor. The changes also place the loss from the FW꧙ in a better place in relation ꧟to the front suspension elements than seen on AT03. 

Front Suspension

The changes in angle of the suspension legs and fairings improves the onset condition of the flow to the floor. They also help to control the loss that is ejected from the wedge where the tyre makes contact with the ground. A loss we call the '💝squish loss'

Front Corner

Removing the intersection with front lower wishbone exposes more of the surface of the wishbone to generate the 💫desired pressure field to control the front tyre wake. The shapꦑing of the brakeduct scoop itself is designed to enhance this effect whilst also improving the loss at the junctions between it and the wishbone legs in comparison to AT03

Floor Body

The ꩲunderfloor profiling is designed to make best use of the vorticity generated by the floor fences and maximise the downforce generated by the floor's close proximity to the ground. The leading edge height change was done to improve performance in a specific part of the ride height envelope of the car that we felt we were weak in last year. Applying the blend detail to the edge of the floor alters the base pressure that the outboard of the fence system sees helping us improꦉve the underfloor vorticity

Floor Edge

The vanes enhance the outwash of the floor wing helping lower the pressure under the floor. Th🐻ey also form vortices that fu🔯rther improve floor loading downstream

Diffuser

The cut out allows higher quality flow 💮from outside of the floor to enter the diffuser and re-e💙nergise the flow under the floor

Sidepod Inlet

Maintaining the inlet size is important in💮 achieving the necessary flow rate to the radiators to cool the car. The raised inlet increases the size of the 'undercut' which allows it to feed be♚tter flow to the floor edges downstream to increase their loading.

Coke/Engine Cover 

The shrinking of the upper engine cover and the ꧅raising of the exit has been done to reduce local lift and improve the onset flow to the rear wing and lower beam wing to allow them to generate more downforce more💖 efficiently. 

Cooling Louvres

The reprofiling and repositioning of the louvres improves the loss that exits from these apertures but also places this loss in a position at the rear of the car that is less damaging for the performance of the beam wing and rear wing. Thi🦩s helps to improve the efficiency of this cooling option

Rear Wing Endplate

The change better🅺 aligns the endplate 💮but also allows increased clearance to the flow features from the rear brakeduct and winglet. As the span reduction of the beam wing is minimal it allows the overall load of the rear wing assembly to increase

Williams upgrades

Nose

Front Wing

These are a combined structu☂ral and aero improvement to deliver higher quality air flow further d🌟own the car

Front Wing

These updates generate more load on the front wing and also deliver cleaner flow further down the car, including into the radiator ducts and the ♎new sidepod ꦉundercut

Front Suspension

In combin🧜ation with the revised brake ducts scoops, the suspension✨ reduces losses and interaction with the wing wake relative to FW44.

Front Corner

The total brake duct system offers sufficient and efficient brake cooling (disc and caliper) and also improves the tyre wake control and works in conjunction with the suspension link updates to produce some adꦚditional local load and improved flow down ൩the car

Coke/Engine Cover

The more aggressive undercut works in conjunction with the entire rearward system on the car, including the new floor edge details, diffuser and outboard brake duct winglet cascade. The undercut delivers higher energy flow to these regions for improved load. The engine cover shape better ac𝐆commodates the cooling louvre options so that we lose less aero performance as we increase the cooling flow through the radiator system 

Rear Wing

The upper elements produce more load and work in conjunction with the revised beam wing arrangement🌌. The pylon geometry is better for local flow control and provides the required stiffness to hold the upper elements in p🎶lace

Beam Wing

These profiles work with the updated rear wing elements described above. The produce additional load locally and also improve the rear wing - diffuser sy🤪stem to further improve the load

Halo

These features better condition the flow coming over and round the cockpit before it feeds the engine cover upper surface and the rear wing system. The roll hoop inlet ensures compliance with the mandated chassis safety tests and also feeds the central radiators wiꦜth sufficient quantity and quality of air flow

Floor Fences

Thes🌳e fences help condition the flow as it progresses along the floor and to the diffuser

Rear Suspension 

This improves 𝔉the section alignment with the local flow and works in conjunction with the revised winglet cluster to generateꦇ increased local load

Rear Corner

This system works with the realigned wis𒀰hbone and toelink to improve wake manage🌟ment and generate more local load

Front Suspension

Floor Edge

Legality𓃲. The changes to the floor edge detail are aimed at recovering as much of the🍌 load lost due to the height change as possible. There is also a detail to improve the state of the spat vortex, which improves the load delivery of the total rear system

Diffuser

Legality. The changes to the diffuser geometry improves control of the wheel wake, woꦦr꧟ks in conjunction with the revised lower beam wing to produce improved load throughout the wing:diffuser system
