McLaren rullar ut en hyper-kärra tillägnad Ayrton Senna

Den ultimata gatlegala banbilen

Bil / McLaren

Modellen som McLaren internt kallat för P15 är nu äntligen officiell, och den heter Senna. Det här är en hyllning till racerföraren Ayrton Senna och beskrivs av tillverkaren som en gatlegal hyperbil för banan. Det här är dock inte ersättaren till P1 utan en modell som kommer att finnas jämte den kommande tresitsiga bilen som internt går under BP23. Eller finnas och finnas, alla 500 stycken exemplar av Senna är redan sålda. För 750 000 pund innan skatt styck. Den sista auktionerades ut i går kväll och den gick för två miljoner pund innan skatt, överskottet gick till stiftelsen Ayrton Senna Foundation.

För slanten har köparna fått en riktig extrem kärra baserad på 720S. Torrvikten ligger på 1 198 kilo vilket gör den här till tillverkarens lättaste gatbil sedan McLaren F1, och hela 220 kilo lättare än modellen den baseras på. Bakom monocoquen i kolfiber sitter den välbekanta V8:an med dubbla turbo på 4,0 liter. Här ger den 800 hästar och 800 newtonmeter. Den kopplas till en sjustegad dubbelkopplingslåda som skickar vidare kraften till bakhjulen. Vad Senna har för prestanda berättar man inte utan säger bara att den kommer att ha "savage performance", och det stämmer troligtvis.

Utseendet kan man ha mycket åsikter om men den ser ut som den gör för att kunna prestera, allt är där av en anledning och har en funktion. Både i fronten och baken finns det aktiv aerodynamik som ser till att marktrycket är det bästa i alla lägen. I luftintagen finns det klaffar som kan öppna och stänga för att styra luften dit det är lämpligast, och den enorma vingen där bak ser till att hålla rumpan i shack när det börjar gå fort. Fjädringen är en uppdaterad version av det som finns på P1 vilket innebär att dämpare och krängningshämmare är aktiva och elektroniskt styrda. Förutom inställningarna Comfort, Sport och Track finns här även ett nyutvecklat Race-läge. Knappar man in det sänker bilen sig ytterligare och styvar upp fjädringen rejält. Knappen har man placerat i taket för extra coolhet, här sitter även start-knappen för att få igång bilen. Bromsarna är keramiska och de mest avancerade McLaren någonsin tagit fram för en gatbil, men vilken dimension de är i får vi inte reda på för tillfället. Som däck har man valt specialtillverkade Pirelli P Zero Trofeo R.

Många grejer känner man igen från McLarens övriga modeller men Senna skiljer sig på ett par punkter ändå. Bland annat så har dörrens sidoruta en delning på mitten, och det finns en extra ruta på dörren för att skapa mer känsla av rymd i kupén. Man kan om man vill istället få en kolfiberpanel här men det är ju klart mycket ballare med så mycket glas. Väl på insidan finns bara det viktigaste och det mest iögonfallande är de extremt skålade stolarna som lär hålla fläsket på plats. Den treekrade ratten saknar helt knappar och annat och framför sig har man bara en mycket smal skärm som visar hastighet och varvtal. Detta är en version av den som finns i 720S men där går den att fälla upp så den blir större, det verkar inte vara fallet här.

Produktionen kommer att dra igång tredje kvartalet nästa år. Bilen kommer att ställas ut på mässan i Genève i mars.

“You commit yourself to such a level where there is no compromise. You give everything you have;
everything, absolutely everything.”
Ayrton Senna
The McLaren Senna has been designed, engineered and developed with single-minded purpose: to be
the ultimate McLaren track-concentrated car for the road. Legalised for road use, but not sanitised to
suit it, the new Ultimate Series deliberately compromises McLaren’s trademark breadth of supercar
daily usability; instead it provides the purest connection between driver and car, to deliver the most
intense circuit experience of any road McLaren.
The technical recipe is classic McLaren Automotive supercar, a pedigree established and earned in the
short time elapsed since the pioneering sports and supercar company was founded in 2010, but taken
to another level entirely in the McLaren Senna. Ultra-lightweight construction, with carbon fibre
chassis and body panels. Mid-mounted, twin-turbocharged V8 McLaren engine. Rear wheel drive.
Sophisticated race-derived suspension that delivers an unparalleled blend of control and dynamic

balance. Electro-hydraulic steering that rewards accurate inputs and gives the purest feedback. And
two seats – but with absolute focus on the importance of the one that the driver occupies.
The carbon fibre Monocage III chassis that forms the core of the McLaren Senna is a further
development of the structure that underpins the McLaren 720S and the strongest monocoque ever
built by McLaren for a road-legal vehicle. Every body panel is made from carbon fibre, in line with a
relentless focus on the weight of every individual component that has resulted in the McLaren Senna
being the lightest road-legal McLaren since the iconic F1 road car, at just 1,198kg*.
With maximum power of 800PS (789bhp), the McLaren Senna enjoys a power-to-weight ratio of
668PS per tonne. This statistic immediately underlines the performance credentials of the newcomer
to the McLaren Ultimate Series, a product family introduced with the McLaren P1TM that is reserved for
the rarest and most extreme McLaren cars.
Unsurprisingly, there are strong echoes in the new McLaren Senna of the incredibly focused
philosophy behind the McLaren P1TM; where the latter was designed to be the best driver’s car on road
and track, the ambition for the McLaren Senna is for it to be the best road-legal track car, setting a
new benchmark for circuit excellence with track prowess absolutely taking precedence.
“The McLaren Senna is a car like no other: the personification of McLaren’s motorsport DNA, legalised
for road use but designed and developed from the outset to excel on a circuit. Every element of this
new Ultimate Series McLaren has an uncompromised performance focus, honed to ensure the purest
possible connection between driver and machine and deliver the ultimate track driving experience in
the way that only a McLaren can.”
Mike Flewitt, Chief Executive Officer, McLaren Automotive
Given the famous name that this new McLaren bears, its unrivalled extreme performance and dynamic
excellence should be no surprise. The legendary Formula 1 racing driver was renowned for his
exceptional powers of concentration and single-minded focus on being the best on the track. The
McLaren Senna driver is hardwired into the dynamic experience the car delivers. Their connection to
the car comes through the steering wheel, the pedals and the seat. Every sensation that comes from
driving at speed is precisely communicated, putting the driver in total control.
The indomitable spirit of Ayrton Senna has always been alive at McLaren and the McLaren Senna will
further amplify his global legacy and link to the McLaren brand.

“Our family is extremely proud of the naming of the new Ultimate Series McLaren Senna. This is the
first project that really connects with Ayrton’s racing spirit and performance. The McLaren Senna
honours my uncle because it is so utterly dedicated to delivering a circuit experience that allows a
driver to be the best they can possibly be. There is an absolute, seamless connection between car and
driver and this pure engagement, these sensory cues that a driver responds to and relies upon, ensure
an experience so focused and immersive that you are left in awe of the depths of excellence the
McLaren Senna possesses.”
Bruno Senna, racing driver and McLaren Ambassador
Visually, the McLaren Senna shocks. The first impression is of an aggressive, unforgiving machine,
organic shapes having given way to a design language that is purposely fragmented in pursuit of
absolute performance. With downforce and aerodynamic balance the guiding principles, this car is the
purest expression yet of the ‘form follows function’ design philosophy embraced by McLaren.
Viewed from above, the body is nature’s most efficient shape – a teardrop – with body components
‘clipped’ onto the cabin to deliver optimal aerodynamic performance. McLaren’s designers went to
extremes by cutting open the ‘shrink-wrapped’ body to reduce weight visually and functionally; while
recognisably a McLaren in proportional terms, you cannot follow a single line from the front to the rear
without it passing through a functional air intake or vent.
The McLaren Senna introduces a new generation of ground-breaking front and rear active
aerodynamics, raising downforce and aero control to an unprecedented level to ensure the
performance potential can be fully exploited. Every element of the body design, from the front splitter
to the double diffuser at the rear, has been developed to optimise downforce and aerodynamic
balance, whether under braking, adjusting the throttle mid corner, or applying power on corner exit.
There is also an opportunity for added visual drama, with the front aero blades available finished in
one of five ‘By McLaren’ theme specifications that include Azura Blue and McLaren Orange. The same
linked accent colour can also feature on the brake calipers, visible door gas struts and seat trims.
Cooling requirements played an equally crucial role in the overall design of the McLaren Senna: the
rear clamshell, for example, was born from the twin demands of aerodynamic and cooling
performance, with prominent ‘gurney’ flaps ahead of a succession of stepped louvres directing air
away from the rear deck and down the sides of the body. The resulting area of low pressure draws hot
air out from the high-temperature radiators and engine bay, with the louvres ensuring that the airflow
does not impact the efficiency of the rear wing. The ‘slash cut’ finishers of the unique Inconel and
titanium exhaust exit through the lowest rear deck (measured at the trailing edge) of any McLaren
road car, the angle of the pipes directing exhaust gas away from the rear wing.

MEDIA

The slim, rear LED taillights have been subject to the same exacting attention to detail as the
headlights and every other aero-relevant component, the single-blade design minimising
interruptions to airflow.
The double diffuser at the rear of the car is unmistakeable. Created as a single piece of carbon fibre, it
begins under the rear axle and as it increases in height accelerates air out from under the vehicle. This
creates a low-pressure zone that sucks the McLaren Senna even tighter to the ground. Equally
unmissable is a huge, double-element carbon fibre rear wing that at its highest point sits 1,219mm
from the road when the car is stationary. Hydraulically actuated and with a planform surface area of
more than 6,500cm2

, the wing constantly adjusts to optimise the levels of downforce and

aerodynamic balance and functions as an airbrake under heavy braking.
The depths of connection with the new Ultimate Series car will be experienced in full once in the
driver’s seat and on a circuit, but the intimate relationship with the McLaren Senna begins before that,
simply by entering the car. McLaren F1-inspired dihedral doors hinge forwards and upwards, opening
with a portion of the roof to expose noticeably low sills and an aperture of sufficient size for drivers or
passengers to easily enter or leave the cockpit, even when wearing a helmet and a race suit.
The doors, which are constructed of carbon fibre, feature two-piece glass side windows with a fixed
top part and a smaller opening section below. Both the door upper (effectively part of the roof) and
the lower half of the door side can be specified with glass as a replacement for the carbon fibre panels
that are standard-fit. This enhances the sense of space inside the cockpit and in the case of the glazed
door lower, dramatically reinforces the visual connection between driver and track environment. To
accommodate the door design, the release mechanisms and window switches are housed alongside
the engine start button in a carbon fibre console above the driver’s head.
The cockpit environment reflects the stripped-back, functional nature that is evident in every aspect
of the McLaren Senna. Visual carbon fibre is used extensively. Dependent on customer preference,
Alcantara® or leather covers the seats, facia and side airbags, but the absence of any other interior
trim both saves weight and reveals the construction of the doors. Even the gas struts are exposed to
save vital grams.

Driver controls have been deliberately kept to a minimum to reduce ‘cockpit clutter’ and the three-
spoke steering wheel is free of buttons and switches, creating a pure focus on sensory feedback. All

the information the driver needs comes from the high-definition McLaren Folding Driver Display and
central infotainment screen. And while McLaren designers stopped short of removing the second seat

altogether, there is no contingency for excess baggage; storage space is restricted to a chamber
behind the seats integral to the Monocage III with just enough room for two helmets and race suits.
Codenamed M840TR, the 4.0-litre twin-turbocharged V8 engine at the heart of the McLaren Senna is
the most powerful road car internal combustion engine ever created by McLaren, producing 800PS
(789bhp) and torque of 800Nm (590 lb ft). The engine’s dry sump lubrication and flat-plane
crankshaft are technologies with their roots in motorsport. Lightweight internal components reduce
mass in the powertrain and combine with ultra-low inertia, twin-scroll turbochargers and
electronically controlled wastegates to deliver lightning-quick throttle responsiveness.
From the outset of the programme, McLaren engineers determined that the full mechanical symphony
of the engine – from intake to combustion to exhaust – had to be central to the sensory experience.
Those fortunate enough to drive the McLaren Senna will feel the cockpit come alive with the sound of
air rushing into the roof-mounted ‘snorkel’ intake and mixing in the carbon fibre plenum, producing

precisely tailored high-frequency sounds that deliver a vivid experience. At the same time, low-
frequency sounds from the engine are transferred into the cockpit through unique engine mounts,

exciting the double-walled rear structure of the carbon fibre Monocage and amplifying every change
in engine revs, making it seem almost as if the V8 is sitting alongside the driver.
A dual-clutch, seamless-shift, seven-speed gearbox delivers power to the rear wheels. A fully
automatic mode is the default, with the driver able to choose full manual control of gear shifts via
paddles mounted on a rocker behind the steering wheel. The elongated carbon fibre paddles are
optimised to be used both with or without racing gloves, and create a deep sense of mechanical
connection with the McLaren Senna.
The character of the 4.0-litre twin-turbo McLaren V8 and the transmission can be tailored using the
Active Dynamics Panel, with the driver having a choice of Comfort, Sport or Track powertrain modes.

Whatever the mode, performance is suitably savage. Throttle response is immediate and neck-
snapping, pinning the driver back into their seat.

“The McLaren Senna delivers true performance, all the way to the limit of a driver’s ability. With a truly
astonishing power-to-weight ratio, this car is about performance that is accessible and attainable, yet
at the same time exciting and challenging for the very best drivers in the world – and with an intense,
sensory experience to match.”
Andy Palmer, Vehicle Line Director, McLaren Ultimate Series

RaceActive Chassis Control II (RCC II) hydraulic suspension works in harmony with front and rear active
aerodynamics and the ultra-rigid Monocage III to deliver an incredibly intensive experience on a circuit.
Every element of the McLaren Senna has been designed to maximise the connection between driver
and car, at all speeds and in every situation. Painstaking work on the damping and steering weight has
ensured that the car feels fully ‘alive’ well below its upper limits; even when the suspension is not fully
loaded and tyres not absolutely compressed, the rich texture of communication blends with the
feedback transmitted to the driver as aero levels and cornering speeds build.
RCC II is a double-wishbone suspension system that additionally features hydraulically interconnected
dampers and a hydraulic replacement for conventional mechanical anti-roll bars. It also further
develops the variable stiffness and ride height technology first seen in the pioneering hydraulic
system in the McLaren P1TM.
The adaptive dampers are interconnected hydraulically, both left to right and front to back, with two
valves per damper to independently adjust for compression and rebound. The stiffness of the McLaren
Senna is separately controlled using a kinetic roll system, or K-damper. The continuously variable RCC II
system advances the control strategy introduced on the McLaren 720S and also adds a Race mode,
which introduces a lower ride height, lower centre of gravity and significantly stiffer suspension.
Dynamic parameters are adjusted by the driver through the Active Dynamics Panel located on the
centre console to select Comfort, Sport or Track modes or via a switch in a roof-mounted panel to
access Race mode.
The braking system of the McLaren Senna is the most advanced ever fitted to a McLaren road car,
using carbon ceramic discs and motorsport technologies to deliver extreme performance. Tyre choice
is equally focused, with bespoke Pirelli P ZeroTM Trofeo R tyres developed in conjunction with McLaren
technical partner, Pirelli. Designed for race tracks but approved for road use, they enable a McLaren
Senna to be driven to a circuit. Only one style of wheel is available: an ultra-lightweight alloy wheel
with a race-inspired centre lock system.
The third model introduced under the McLaren Track22 business plan, the McLaren Senna will be
hand-assembled in England at the McLaren Production Centre. Production will be limited to 500
vehicles, each costing from £750,000 including taxes (UK price) and all already allocated.

The ultimate road-legal, track-concentrated McLaren hypercar will make its public debut in March, at
the 88th Geneva International Motor Show. More information about the McLaren Senna, together with
images and films, is available now at http://cars.mclaren.com/ultimate-series/mclaren-senna.
