The Mercedes-AMG F1 W15 E Performance, commonly known as the Mercedes W15, is designed and built by the Mercedes-AMG Petronas F1 Team to compete in the 2024 Formula One World Championship. This was the first Mercedes car fully designed under British designer and engineer James Allison since his return as technical director in 2023. The W15 was raced by returning drivers George Russell, and seven-time World Drivers' Champion Lewis Hamilton, the latter in his final season with the team. Andrea Kimi Antonelli served as a test driver. The W15 achieved four race wins, four pole positions, four fastest laps and nine podium finishes; Russell won the Austrian and Las Vegas Grands Prix, whilst Hamilton won the British and Belgian Grands Prix. Mercedes finished in fourth place in the World Constructors' Championship, their lowest finish since 2012.
