The Mercedes team said last week that it has stopped developing this year's car, while Red Bull and Verstappen are still busy improving their cars. This week's Portuguese Grand Prix, they continue to bring upgrades.
It is logical for Mercedes to stop developing this year's car because they have a huge advantage now. They believe that they have won the championship, so they want to focus on next year. In order to narrow the distance between the car and Mercedes, Red Bull Racing continued to upgrade this year's car.
On Tuesday, reporters Mark Hughes and George Piola explained in detail Red Bull Racing’s upgrade moves. One of them was the adoption of a new rear wing for the Eifel Grand Prix. This upgrade will allow air to flow through the rear wing faster. This produces more downforce.
The Red Bull Racing team originally planned to upgrade the front wing at the Eifel Grand Prix. Many small holes were opened in the "fender" to ensure a more effective flow of air above the tires.
