F1TECH: McLaren introduce two-part aerodynamic upgrade package at Spa
McLaren has arrived at Spa-Francorchamps with a focused two-part aerodynamic upgrade package, introducing revisions to its rear wing in a bid to maximise efficiency at one of Formula One's fastest circuits.
The championship-leading team has brought a circuit-specific rear wing assembly alongside a revised rear wing endplate, with both developments aimed at improving aerodynamic performance while reducing drag on Spa's long, high-speed straights.
Spa-specific rear wing targets lower dragThe headline addition is a new rear wing assembly developed specifically for the Belgian Grand Prix. Spa-Francorchamps places unique aerodynamic demands on Formula One cars, requiring teams to strike a delicate balance between straight-line speed and sufficient downforce through the circuit's sweeping corners.
McLaren says the new rear wing has been designed to deliver a more efficient reduction in drag without compromising overall performance.
"A new rear wing assembly specifically designed for the increased isochronal of this circuit, resulting in an efficient reduction of drag in straight line and cornering mode."
By reducing aerodynamic resistance, the package is expected to improve top speed along Spa's lengthy flat-out sections, including the Kemmel Straight and the run from Stavelot to the Bus Stop chicane.
Revised endplates improve airflowAlongside the circuit-specific rear wing, McLaren has introduced a subtle revision to the rear wing endplates. Although less visually striking, the update is intended to improve airflow management across a wide range of operating conditions.
According to the team's technical submission, the modification enhances both flow conditioning and the aerodynamic characteristics of the rear wing.
"A small revision to the rear wing endplate resulting in improved flow conditioning and aerodynamic characteristics across the full operating range."
Improved airflow around the rear wing can increase aerodynamic consistency, helping the car remain stable under varying speeds, cornering loads and ride heights throughout a lap.
