"Mercedes W15 F1 Car: Speed Boost, Emotional Farewell, and Complete Relaunch"

Mercedes unveiled its new W15 F1 car with a focus on addressing the unpredictable rear end characteristics of its previous ground effect cars, aiming to create a more reassuring and stable driving experience for Lewis Hamilton and George Russell. The team made significant aero and mechanical changes, including a switch to its own push-rod rear suspension and a new gearbox design, to improve handling and aero efficiency, particularly when DRS is open. Despite operating under a cost cap, Mercedes invested in a new chassis and gearbox casing while being mindful of overspending in other areas, aiming to make strategic improvements without breaking the bank.
