McLaren P15: extreme super sports car from the rear, shown in the new preview image

McLaren has shown, the rear of its most extreme, track-focused road car yet to confirm that it launches next year. The model will be revealed in full on 10 December.

Published as two separate images, the previously published and with a well-known today, the recording is created when the two previews that are sewn together.

Referred to internally as the P15, the forthcoming Ultimate series model, scooped by Autocar earlier this year, is designed with a hard focus on the track – so much so that the Woking-the manufacturer admits that it is a victim of the daily usability, in order to maximize performance.

The two-seater because of its public debut at the Geneva motor show in March, sporting, what McLaren calls “brutal” design, the “purest expression” of the form-follows-function Design.

Autocar understands that the 675LT development car has been spotted testing at the Nurburgring in recent weeks, is a mule for the P15, offers insight into the advanced aerodynamic layout of the final production car.

The mule bodywork with large air intakes on the nose, which are designed to channel air out of vents on the hood and directly to you about the car is the windshield. Such a system is used by the P15, that means it ditches the front-of-boat for the benefit of the aerodynamic efficiency. The mule also carries a large rear wing, is held in Position by two centrally-mounted Swan-neck arms. A source revealed that the mounting arms are attached so that the wings do not fold away into the rear deck, but it has been suggested that the wings could rotate, in a similar way as the drag reduction system fitted to formula 1 cars.

It is assumed that the P15 is omitted, a hybrid drive, such as the P1, for a lighter, the combustion engine-only set – up. The Motor is on the basis of the M840T-Turbo 4.0-Liter V8 used in the 720S but feature updated internals and a custom turbocharger set-up boost power, far beyond the 710bhp offered by the 720S Super-serial model. A raised value of around 789bhp the P15 – V8 62bhp advantage over the 3.8-Liter internal combustion engine featured in the hybrid-P1 drivetrain would give.

The P15 is built to McLaren Monocage II one-piece carbon-fiber tub, and the company is the most pared-back-road model to date. It is a racing-inspired interior with seats adapted from the world of motorsport, and little in the way of passenger comfort. The P15 is expected to weigh less than 1300kg – significantly lighter than the 1547kg P1 and enough to ensure that its power-to-weight ratio eclipse, the model of the figure of 647bhp per ton.

McLaren is expected to produce 500 examples of the S15, which is awarded each already-for a price of around £840,000 in the UK.

Customers will be invited to a private screening of the vehicle before the end of this year, and this is in front of the car. December 10 show date. The name is also confirmed later in 2017. The first deliveries will be in summer of next year, close to when the next Ultimate-series-model, the three-seater-codenamed BP23, is due to be revealed.
