The changes to the W15 have benefited the team after Russell acquired pole position and a podium at the Canadian Grand Prix.
However, Formula1uno reports that Red Bull engineers, under the supervision of Paul Monaghan, will examine the new Mercedes front wing.
Is Mercedes’ front wing legal?
The request has been submitted to specifically monitor the flexing at the W15’s front wing and nose.
According to the FIA’s static checks, Mercedes' front wing has always been within the legal limits, but Red Bull have still asked to take a closer look at it.
There are fears the updated front wing flexes more compared to the initial specification, and the FIA will decide if there has been any infringement after the request is completed.
Despite the monitoring request, Red Bull’s team boss, Christian Horner, remained unbothered by Mercedes' pace advantage after the race.
“Even with our downgrade, we managed to beat their upgrade,” Horner said to the media.
“It was a rewarding race to win. The last couple of races have been more choppy waters for us but we have still managed to win two out of the last three races.
“We had a pole in Imola, we managed to match the pole time here with a car that both drivers are feeling its deficiencies. So there is a lot of focus on that to see if we can improve that.”
