Ferrari, Renault and Toro Rosso were just some of the teams to have been spotted with shallow rear wings on Thursday, which are aimed to boost straight-line speed. The run from La Source to Les Combes often rewards the cars with the least amount of drag, as does the final sector blast through Blanchimont as top speed contributes to a large portion of the lap spent at full throttle.

Using a rear wing with a low angle of attack reduces the overall front area, helping the cars to achieve a lower percentage of drag, and the approaches are demonstrated in Giorgio Piola’s images (Click the arrows on the images below to cycle through them)…

’s wing seems to be a simple, lower-downforce interpretation of its usual design, retaining the same endplates and shifting the leading edge of the mainplane further up, using a short-chord top element to increase that effect. In addition, the team has brought the same front wing construction it used in , with a short-chord top element to further enhance the low-drag properties of the wing.

has done the same with its rear wing elements, but has taken another step by amending the endplates. So far this season, the team has run with a number of serrations to more aggressively manage the airflow emerging from the rear of the car, but has opted for a -style overhang without splitting it into strakes. This retains the expansion of airflow at the rear to boost diffuser suction, without generating quite as much turbulence – the car loses some further downforce, but inhibits a healthy portion of drag.

has a similar approach to , in that it appears to be a lower-downforce version of its usual wing concept, retaining the same endplates and the deeper central section.

has also been spotted with a low-downforce wing, using a distinctly short top flap chord to ensure the team runs as little wing as possible.


Overall, these wing configurations may cost a small amount of performance on the sector from Les Combes to Pouhon, but the benefits on offer from optimising acceleration and straight-line speed largely outweigh them.
