Audi has debuted a significantly revised sidepod design on its R26 car during the Formula 1 pre-season test in Bahrain ahead of the 2026 season. The changes move away from the conventional setup used in earlier Barcelona sessions, focusing on improved airflow management and cooling efficiency. Driver Gabriel Bortoleto began running with the updated configuration on Wednesday morning.
The Bahrain International Circuit provided the first public glimpse of Audi's evolved aerodynamic package for the 2026 Formula 1 season. Following an initial shakedown and closed testing in Barcelona during early January, where the R26 featured a more conventional inwashing sidepod approach with tucked-in rear edges and a smoother upper surface, the team introduced a more complex design in Bahrain.
Key modifications to the sidepods include narrower and taller air inlets positioned alongside the chassis flanks. These inlets flare outward, incorporating a ramped undercut that directs airflow toward the floor edges. A channel on the top surface facilitates smoother passage of air to the rear, reducing energy loss as it reaches the diffuser. The bodywork is shrink-wrapped around the side impact structures, featuring a small blister near the mirror mounting and an undercut ramp for the lower structure.
This positioning aims to protect cooling from turbulence generated by the front tires, ensuring a more consistent airflow rate, particularly during cornering when sidepods can better manage tire-shed airflow. Observations from the pitlane indicate that the lower crash structure has been raised, opening the floor's leading edge to potentially allow higher ride heights while maintaining flow rates through the floor.
Additionally, Audi has updated its front wing with twin active-aero actuators instead of a central one under the nose, minimizing blockage. Outwashing fins atop the vortex tunnels enhance interaction with endplate winglets to direct airflow around the front tires. The front wing also includes tweaks to flap profiles and two large housings, possibly for adjustments or measurements.
These developments reflect Audi's ongoing factory work, with further parts expected before the season opener in Australia.
