Ferrari‘s new rear wing for the SF-23 showcased revised mainplane and top flap layouts, with a flattened central spoon-shaped section and a steeper gradient in the outboard section. The wing also features a more conventional square edge layout for the tip section of the endplate. Red Bull continued to use a lower downforce rear wing with a single beam wing element for reduced drag on the straights without compromising performance in turns.
Mercedes focused on the upper corner cut-out section of the endplate, with subtle changes made to the shape and tip section to improve flow around its upper corner. The team carried various cut-out and infill panels to adjust trim levels. Alpine‘s rear wing design boasts a unique approach, with recessed mainplane and upper flap leading edges significantly reducing the allowable box region. The front wing also features a crescent-shaped section cut out of the upper flap’s inboard end, balancing out the car.
McLaren unveiled a new rear wing and beam wing layout suited for the street circuit requirements. The new rear wing has a variation of a spoon shape, with amended curvature to reduce drag while retaining downforce. The top flap’s trailing edge further improves top speed and includes a central strip to maintain DRS mechanism attachment. The beam wing features a biplane arrangement, improving the relationship between the diffuser and upper rear wing elements.
Aston Martin introduced a new top flap with trimmed trailing edge in Azerbaijan, but struggled with DRS issues throughout the weekend. Alfa Romeo opted for a trimmed trailing edge, paired with a sawn-off tip section of the endplate and a biplane beam wing layout. Haas aggressively trimmed its upper flap’s trailing edge and only fitted the lower beam wing element. AlphaTauri‘s new rear wing was designed with reduced drag in mind and offered two beam wing variants, but only used the lower single element version to trim for the circuit’s demands.
Williams did not have a new low downforce rear wing but added a trimmed beam wing variant suitable for Baku’s downforce and drag levels. Ferrari, Red Bull, and Alfa Romeo preferred a sawn-off tip section for their endplates before with the new Ferrari variant returned to a square edge layout. Mercedes designed their endplate to quickly change the upper corner cut-out section without fully dismantling the entire wing. McLaren‘s beam wing displace the upper element from the lower one to improve the relationship between the diffuser and upper rear wing elements.
