Red Bull implemented significant changes to their car, the RB20, taking inspiration from Mercedes in 2-24. Christian Horner, along with Toto Wolff, discussed the modifications made to the new challenger. Despite their previous success with the RB19, Red Bull decided to adopt a more aggressive approach. The design of the RB20, particularly the side pods and engine cover, bears resemblance to the abandoned Mercedes concept used in the W14.
According to Mercedes team principal, the RB20 shares similarities with their 2022 and 2023 car designs, which they have since moved away from. The “Great Wall” engine cover and side pods are reminiscent of the W13/W14 series, but Wolff suggests that the true secrets lie hidden.
Wolff acknowledges that Red Bull has excelled in certain areas in recent years. While there may have been further developments, the initial appearance of the bodywork may not indicate a significant conceptual shift. He also mentions that Red Bull chose to follow the advice of the wind tunnel rather than solely relying on proven ideas.
Mercedes has made changes to the front suspension and chassis, allowing for easier adjustments to optimize the setup for each track. Their design provides them with more freedom compared to other teams, who usually have limited flexibility. This design enables Mercedes to tailor the inboard end of the suspension leg according to their requirements.
Initially, this move was seen as a diversionary tactic during the preseason to intimidate rival teams. The larger hatch on the side of the chassis allows for different wishbone configurations, resulting in unique kinematic and aerodynamic responses. Mercedes experimented with mounting the upper wishbone’s rear leg at different heights during the preseason test to evaluate its effectiveness.
The W15 design by Mercedes offers various benefits depending on the chosen position, incorporating a multiple mounting-point arrangement with anti-dive features. This arrangement could give Mercedes an advantage in circuits where other drivers are limited to less favorable configurations. While this is a new arrangement for Mercedes, the company has previously explored innovative suspension designs.
