The McLaren P1 made a brief appearance at the launch of the Vodafone McLaren Mercedes Formula 1 car, the MP4-28. Jensen Button turned up to the launch event in the camouflaged XP prototype while teammate Sergio Perez arrived in an orange MP4-12C Spider.
Launching the new racing car also formally marked the start of the company's 50th anniversary celebrations. McLaren gathered together some of its previous race and championship winning cars including the M8D CanAm car from the 1970s, Ayrton Senna's MP4/4 from 1988 and the most recent championship winner the 2008 MP4-23.
