Autocar has got some juicy rumours for us regarding a new McLaren hypercar. The British publication has inside sources claiming that a new model will be added to the Ultimate Series just after the P1 hypercar, and they claim that it will be the “most extreme, track-focused car” they have ever made. This high-performance machine, dubbed “P15” is McLaren’s “track weapon”, is expected to be even better than the P1 GTR.
We are aware that the P1 GTR, excluding the LM model, was restricted only to the track due to its power. But apparently, the P15 (which is even more powerful) will be road-legal. It will be given a biturbo 3.8-liter V8 engine that has been modified, instead of the 4.0-liter inside the 720S. And this powertrain can generate 789 horsepower, which is even greater than the P1’s 727 horsepower with its combustion engine. Though keep in mind that the P1 can be pushed to give out a maximum of 903 horsepower with its hybrid powertrain.
Insiders say that the P15 will have a total curb weight of below 1,300 kilograms (2,866 pounds). That makes it 247 kilos (544 pounds) lighter than the P1, which means that it can go so much faster with the lighter body. All the lost weight results from losing the electric motor, and the use of a one-piece carbon fiber tub like that of the 720S, fully covered in carbon fiber.
This project is the result of McLaren’s aim to focus on the car’s performance. And of course, this will have an impact on the exterior design and aerodynamics. Sources say that the P15 will have a huge rear wing and a massive front spoiler, combined with self-adjusting front and rear spoilers. Do not expect it to have a lot of cargo space as the design focuses on performance more than space.
The interior will most likely only include the very bare basics for a road-legal vehicle. This is because anything else that will be added will just be a burden to the extremely lightweight hypercar.
Though nothing has been officially announced yet, rumors say that the P15 will be revealed before 2018, and it will only be limited to 500 examples. We’ve also heard whispers that McLaren might even produce a track-only GTR version of it.
In 2019, McLaren plans to come out with the F1’s spiritual successor, a three-seater model that has been given the codename “BP23”, with a $2.5 million price tag. It’s already sold out, in case you were wondering.
