McLaren will soon introduce its third Ultimate Series model.

McLaren has announced that it will unveil the next model in its Ultimate Series on December 10. The new model will technically be the third vehicle launched under the Ultimate Series banner, following the P1 and P1 GTR.

The new Ultimate Series model— believed to be called P15 — will debut virtually on December 10, followed by an in-the-flesh unveiling in early 2018 at the Geneva Motor Show. McLaren is keeping the vehicle's details a secret until then, but promises "the new Ultimate Series car will be the ultimate track-concentrated McLaren."

Shortly after the introduction of the P15, McLaren says it will unveil another Ultimate Series model known internally as the BP23. Billed as the "world's first Hyper-GT," it's rumored that the BP23 could have a 1+2 seating arrangement like the iconic McLaren F1.
