Red Bull were starting to miss their duck resembling noses and hence changed the previous one to one that more fits its tradition. The new nose is wider and also slightly higher than the version which the team used for the first 7 Grand Prix. In order to prevent the obligated camera housing from mixing up the airflow too much, the team chose to move them forward as much as possible, effectively putting them to use as straighteners for the airflow alongside the nose cone.
Also note the marked ride height sensor that it attached in a carbon fibre hub under the nose cone. It was used on Friday by the team to measure the influence of the car's new parts - which also include a new diffuser.
