Red Bull Racing’s RB19 might have set the standard for others to follow so far this season but in Singapore the championship-leading team have taken inspiration from elsewhere for a new rear wing endplate it has brought to the Marina Bay Street Circuit.

In this weekend’s FIA Car Presentation the team explain that “taking inspiration from competitor designs, the end of the flap element has a revised curl to the endplate which offered more local load for this element for this particular upper wing design”. The design adheres to ideas introduced earlier in the season by Alpine and Aston Martin and then adopted by Ferrari and Mercedes. 

Red Bull have also been busy, again, with the floor edges of its car, with more camber being applied to the forward part of the floor edge wing “resulting in more local load from this region of the floor assembly”. 

But while the Milton Keynes squad have made subtle changes to the RB19, down the road in Woking, McLaren have been far busier still and the British team has brought another raft of updates to the MCL60 for this race. 

The package involves a suite of changes to the bodywork, including new sidepod inlets, reshaped sidepods and as a consequence a new engine cover. The front wing benefits from a new end plate, while the Halo gets new furniture to integrate with the revised bodywork. 

Working in parallel with the alterations, the team has also brought a “fully revised floor”, featuring updated fences, a new floor edge as well as alterations to the diffuser shape, which “in conjunction with the revised bodywork shape results in an increase in aerodynamic load”.

The updates continue at the back of the cart with revised brake ducts and new beam wing, which McLaren believe will also bring more load. 

AlphaTauri, too, have a sizeable new package in Singapore, with a new floor and floor edges and a new diffuser being the headline changes. It calls the new floor “an evolution of the existing design” while the floor edge “local to the trailing edge of the forward floor fences has been modified. The rear floor edge and floor edge wing have also been revised” to improve airflow. The diffuser has been modified to work with the changed floor, “enhancing the strength of the rear floor edge vorticity" and "giving a local load gain within the diffuser”. The Faenza team have also brought a new engine cover which it says will work better with the new floor edges. 

Lastly at AlphaTauri, the team has also brought circuit-specific sidepod inlets aimed at improving cooling at this “or any other high cooling demand circuits this season”. 

Alpine have also made changes to the sidepod inlets and beam wing of its A523. The new sidepods have been raised and staggered and also feature an increased undercut and revised mirror housing stay and winglets and the team believes the design will “Increase overall load especially at higher cooling levels through improved flow to the rear of the car”. The cooling louvres have also been altered to work better with the new sidepods

Further back, the new beam wing is circuit specific and features a taller lip on the trailing edge of the wing to “increases top rear wing load for a gain at high downforce levels” as we have at the Marina Bay Street Circuit. 

Alfa Romeo, meanwhile, have largely focused on the floor and rear of the C43. The Hinwil squad has redesigned the floor fences and floor geometry, revised the diffuser and changed the rear brake ducts, all in pursuit of “aerodynamic efficiency”. Alfa have also made minor changes to the front wing, with an updated flap providing more set-up options for the car, as well as improving the efficiency of the whole aerodynamic flow of the car. 

There are just minor changes at Ferrari, Mercedes and Aston Martin, with the Scuderia bringing a reprofiled front wing flap, the Silver Arrows unveiling circuit-specific, wider front brake duct inlets and exits, while Aston have brought revised deflectors at the rear of the car to create more downforce. Williams introduce a circuit-specific, larger gurney flap available for the rearward most element of the front wing to improve balance at this track and there are no changes at Haas. 

You can see the full list of changes below as submitted by the teams below, and keep an eye out for the next round of changes ahead of next week’s 2023 FIA Formula 1 Japanese Grand Prix.
