We can now confirm our new Ultimate Series - codenamed P15 - will be revealed on December 10th. At exactly one minute past midnight, the world will get its first sight of a road-legal track car unlike anything we've built before. It's time to get excited.#McLaren #UltimateSeries pic.twitter.com/A71efmM0fn
