The rear of what McLaren says will be its most extreme, track-focused road car yet was also revealed earlier this year, following confirmation that it will launch next year.
Released as two separate images, one previously released and one revealed today, the shot is created when the two previews are stitched together.
Brazilian F1 legend Senna drove for McLaren's F1 team from 1988 until 1993, winning all three of his titles - in '88, '90 and '91 - with the team. He also took 35 of his 41 career race wins behind the wheel of a McLaren.
Referred to internally as the P15, the forthcoming Ultimate Series model, scooped by Autocar earlier this year, is being developed with a hard focus on track driving – so much so that the Woking-based manufacturer admits that it will sacrifice daily usability in order to maximise performance.
McLaren hyper-GT three-seat development mule
The two-seater is due to make its public debut at the Geneva motor show in March, sporting what McLaren calls a “brutal” design representing the “purest expression” of its form-follows-function styling.
Autocar understands the 675LT development car that has been spotted testing at the Nürburgring in recent weeks is a mule for the Senna, offering insight into the advanced aerodynamic layout of the final production car.
The mule’s bodywork features large intakes on the nose that are designed to channel air out of openings on the bonnet and direct it around the car’s windscreen. Such a system will be employed by the P15, meaning it ditches a front boot in favour of aerodynamic efficiency. The mule also wears a large rear wing, held in place by two centrally mounted swan neck arms. A source revealed that the mounting arms will be fixed so the wing can’t fold away into the rear deck, but it was suggested that the wing itself could rotate in a similar way to the drag reduction system fitted to Formula 1 cars.
It is understood that the P15 will forgo a hybrid drivetrain, as used by the P1, for a lighter, combustion engine-only set- up. The engine will be based on the M840T turbocharged 4.0-litre V8 used by the 720S but will feature upgraded internals and a bespoke turbocharger set-up to boost power far beyond the 710bhp offered by the 720S Super Series model. A mooted figure of around 789bhp would give the P15’s V8 a 62bhp advantage over the 3.8-litre combustion engine featured in the hybrid P1’s drivetrain.
