The project is billed as the ultimate track car yet street legal, though "daily usability is being sacrificed."

McLaren has officially confirmed its second Ultimate Series model, referred to as the P15.The car is billed as the world's first "Hyper-GT," the company's most extreme track-concentrated model that can still be legally driven on public roads.

"Daily usability is being sacrificed to give the most intensive driver experience around a circuit," McLaren warns. "Its design, described as brutal, will be the purest expression yet of the company's 'form follows function' philosophy."

The P15 will be officially revealed in the first quarter of 2018, though McLaren promises to share more details before the end of this year.

The British marque is also working on another Hyper-GT, known as the BP23, that revives the F1's iconic 1+2 layout. It is expected to be delivered in 2019 as the most powerful and aerodynamic road-going McLaren yet.
