The latest Ultimate Series is a track-ready tribute to Ayrton Senna

A successful race car builder from the 1960s to the 1980s, McLaren began making a name for itself as a road car manufacturer in the early 1990s with the F1. Launched with many benchmarks, including the first carbon-fiber construction, the F1 became one of the most iconic supercars ever made. It was so great that it took McLaren 15 years to gives us a predecessor, the P1, introduced at the 2013 Geneva Motor Show. Four years have passed, and the McLaren Ultimate Series is entering a new era with a brand-new supercar. Codenamed the P15 and in the rumor mill for a couple of years now, the McLaren Senna was unveiled on December 9, 2017, as the company’s ultimate road-legal race car.

A unique design that brings together styling cues from the P1, 720S, and new aerodynamic features, the Senna bears the name of F1 driver Ayrton Senna, who drove McLaren Formula One cars for six years, from 1988 to 1993.

While the Senna’s aggressive design and aerodynamics aren’t surprising, the fact that it’s not a hybrid comes as a bit of shock. With its predecessor sporting an electric motor, the new Ultimate Series was expected to have a similar layout. The same goes for the interior, which has a standard left-hand-drive configuration, despite prototypes that have a mid-mounted driver’s seat, like the old F1. But this doesn’t make the Senna a less spectacular supercar. On the contrary!

It's body is composed off all carbon fiber
The organic styling cues, the teardrop shape, and the massive rear wing put the Senna in a league of its own

It’s basically impossible to describe a car like this with one work, but if I were forced to do it, I’d use "extreme." Actually, make that "extreme!!!" Granted, the P1 and the 720S are also pretty extreme styling-wise, but the Senna just takes things to a new level. Its organic styling cues, the teardrop shape, and the massive rear wing put it in a league of its own.

The front fascia is a significant departure from previous McLaren designs, not so much in aesthetics as in aerodynamics. There are a few recognizable features, like the split hood from the P1 (but in a more aggressive form here) and the slim headlamps carved into the body. But everything else is new. The nose is more angular, and the intake underneath is bigger. The vents under each headlamp make it seem as if the nose simply floats above the splitter.

The Next McLaren Model?
Codenamed: BP23
It's pretty much an open wheeler design with full fenders and a closed cockpit

Things become more extreme onto the sides. Whereas previous McLaren’s had a rather traditional design with the body becoming increasingly wider toward the rear, the Senna is narrowed between the front and rear fenders. The shape is somewhat similar to Formula One and IndyCar vehicles, with the wide side skirts acting like side pods. It’s pretty much an open wheeler design with full fenders and a closed cockpit. The design may seem radical, but it has nothing to do with styling. Everything was conceived in the wind tunnel. When seen from above, the Senna has a teardrop shape, and all the components seem clipped onto the cabin. The narrower center section also helps with cooling, having enabled McLaren to fit massive vents into the rear fenders and the side skirts.

Around back, the Senna has nothing in common with previous McLarens. While both the P1 and 720S have organic designs with lots of flowing lines, the Senna’s rear fascia is all about horizontal features. The deck is pretty flat too, as is the upper side of the diffuser, which sticks out a few good inches from the body. The rear fenders also have a unique design, raising above the decklid to create to create an aerodynamically optimized area. The fenders are backed by prominent gurney flaps that direct air away from the rear deck. The exhaust pipes are placed on the decklid too, facing upward, yet another unique design.

Virtually no competition on the market
The double-element carbon-fiber rear wing sits four feet from the road at its highest point

Below, there are slim LED taillights almost hidden underneath the edge of the decklid. The simple design is also the result of intense aero testing, as they minimize interruption to airflow. The double diffuser is just as wide as the rear fascia and uses its unique design to create a low-pressure zone that sucks the car tighter to the ground. The visual drama is completed by the double-element carbon-fiber rear wing. Sitting four feet from the road at its highest point, the wing has almost vertical stanchions and massive side pods. The design is rather unusual for a road car, being closer to something you’d find on a full-fledged race car, but it proves that McLaren made no compromises on its way to finding the best aerodynamics.

Speaking of which, both the front and rear section feature active, carbon-fiber, aerodynamics and McLaren claims they raise downforce and aero control to "an unprecedented level." Specifically, the Senna generates a whopping 800 kg (nearly 1,764 pounds) of downforce at 155 mph. That’s 200 kg (441 pounds) more than the P1 at the same speed and 160 kg (353 pounds) more than the Ferrari FXX K Evo achieves at 124 mph! This tremendous amount of downforce improves cornering and enables the driver to break later, turn it later, and accelerate earlier than usual.

All told, the McLaren Senna is dramatic to say the least and, while it’s not the prettiest car the British firm has built so far, its aerodynamics and functionality should be superior to the P1 and maybe even the track-only P1 GTR!

Interior

  • F1-inspired doors
  • Carbon-fiber everything
  • Clutter-free dashboard
  • Racing seats
  • Folding Drive Display
  • Storage for helmets and racing suits

Will feature that central driver layout...
based on the McLaren F1
The carbon-fiber cockpit is inspired by the world of racing

To get inside the cabin, you need to open the F1-inspired dihedral doors that hinge forward and upward, opening with a portion of the roof. This system provides an aperture of sufficient size for drivers and passengers to enter or exit the cockpit even when wearing a helmet and a race suit. It pretty obvious that while road legal, the Senna is aimed at customers who spend a lot of time at the track. The doors have two-piece glass windows for proper insulation, with a fixed top part and a smaller opening section below.

As you’d expect from a top-of-the-league McLaren, the Senna’s cockpit is inspired by the world of racing. Carbon-fiber was used extensively on the dashboard, center console, door panels, seats, and even the steering wheel. Unlike other modern supercars, the steering wheel is free of buttons and switches, while driver controls on the center console have been kept to a minimum. Most functions are operated through the vertical infotainment screen attached to the dashboard, which also includes buttons for the manual transmission setup and the ESC system. Further information is available on the Folding Driver Display, which we first saw in the McLaren 720S.

Minimized, track-focused interior
The Folding Drive Display keeps the driver focused on the race track

Designed to rotate around its horizontal axis, the Folding Drive Display provides a comprehensive range of information in its regular, upright position, and switches to Slim Display Model to show only essential data on a small strip, just line in a race car. The idea is to keep the driver focused on the important info while driving at the track, which makes a lot of sense in a car like the Senna.

The carbon-fiber seats have heavy bolstering. The can be had in either Alcantara or leather and have an "S" letter embossed on the headrests. They don’t look very comfortable for cruising, but they provide the utmost lateral support on twisty race tracks.

Storage space is restricted to a chamber behind the seats, with just enough room for two helmets and race suits. Yup, that’s far from practical, but as a customer, you should feel lucky that McLaren made an effort to add a bit of room in there. The Brits almost removed the second seat, so space for two helmets is actually a bit of a compromise.

Cargo space limited to

Storage space is restricted to a chamber behind the seats, with just enough room for two helmets and race suits

Another interesting feature lies atop the cabin and has to do with the experience of driving a road-legal race car. The "snorkel" intake on the roof produces "precisely tailored high-frequency" sounds that make the cockpit come alive under full throttle. In addition, low-frequency sounds from the engine are transferred into the cockpit through unique engine mounts. The double-walled rear structure of the carbon fiber Monocage absorb these vibrations and amplify every change in engine revs, making it seem almost as if the powerplant is "sitting alongside the driver."

Sounds exciting but, unfortunately, not many of us will get to experience that anytime soon.

Drivetrain

  • Upgraded carbon-fiber tub
  • Weighs only 2,641 pounds
  • Twin-turbo, 4.0-liter V-8
  • 789 horsepower
  • 590 pound-feet of torque
  • Dual-clutch, seven-speed transmission

This twin-turbo beast delivers 789 HP and 590 LB-FT of Torque
The carbon-fiber tub is a further development of the structure in the 720S

Much like its predecessor, the Senna is built around a carbon-fiber tub. It’s called the Monocage III, and it’s a further development of the structure in the 720S, itself an upgrade over the P1’s. McLaren claims it’s the strongest monocoque it has built. It’s also incredible light and contributes to a supercar that tips the scales at an impressive 1,198 kg (2,641 pounds). It’s a bit heavier than the F1, which weighed in at 1,138 kg (2,509 pounds), but it’s very impressive for a modern supercar.

Power comes from an upgraded version of the twin-turbo, 4.0-liter V-8 engine that McLaren introduced in the 720S. On top of the upgraded components, the powerplant also gained lighter internals. Although the successor to the P1 was expected to be a hybrid, there’s no electric motor in the Senna. The decision is somewhat awkward given McLaren’s aim to electrify its entire lineup, but maybe the Brits are planning another supercar with a gasoline-electric combo.

But despite not being backed by an electric motor, the V-8 is plenty powerful, being rated at 789 horsepower and 590 pound-feet of torque. That’s an extra 79 horsepower and 22 pound-feet of twist over the 720S. Compared to the P1 in gasoline-only mode, it’s a 62-horsepower and 59-pound-foot upgrade. However, the Senna is actually 114 horsepower and 133 pound-feet below the P1’s total hybrid rating. It’s a bit disappointing that a brand-new supercar is less powerful than its predecessor, but the better power-to-weight ratio (659 horsepower per tonne vs. 647) and the superior aerodynamics make the Senna quicker and more agile.

The sprint from 0 to 60 mph comes in 2.7 seconds, a tenth-second quicker than the P1. Charging to 124 mph takes 6.8 clicks, a full second quicker than the awesome 720S. The quarter-mile time is equally impressive at 9.9 seconds, while stopping from 124 mph takes only 100 meters (328 feet). Top speed is rated at "only" 211 mph, six mph below the P1. The Senna is also a half-second slower from 0 to 186 mph, but this decrease is normal given the extreme downforce.

Beyond the power rating, the V-8 uses motorsport-honed dry sump lubrication and a flat-plane crankshaft. A dual-clutch, seamless-shift, seven-speed transmission delivers the power to the rear wheels. The fully automatic mode is default, but the driver can choose full manual control of gear shifts via carbon-fiber paddles mounted behind the steering wheel.

Suspension and Brakes

Carbon ceramic brakes and ultralightweight alloy wheels
Pirelli P Zero Trofeo R Tires

The Senna rides on a RaceActive Chassis Control II hydraulic suspension that works in conjunction with the front and rear active aerodynamics system. The double-wishbone features hydraulically interconnected dampers and hydraulic anti-roll bars instead of the conventional mechanical units. The whole system is a further development of the variable stiffness and ride height technology first seen in the McLaren P1

The stiffness is controlled using a kinetic roll system, while a new Race mode lowers the ride height, lowers the center of gravity, and stiffens the suspension.

Stooping power comes from a new, advanced braking system with carbon-ceramic discs. The wheels, which are limited to just one design with a race-spec center nut, come wrapped in bespoke Pirelli P Zero Trofeo R tires. Made specifically for the McLaren Senna, these tires were designed for the race track but approved for road use.

Prices

Deliberate Aerodynamics
include a double diffuser and constantly active rear spoiler

Pricing for the McLaren Senna starts from £750,000 including taxes in the United Kingdom. This converts to around $1 million as of December 2017, but we’ll have to wait for official pricing for the U.S. market for an exact figure.

Interestingly enough, the Senna costs less than the P1, which retailed from £866,000 in the U.K. Having said that, it’s likely that U.S.pricing for the Senna will be lower than the P1, so expect it to fetch less than $1.35 million. I’d venture to say that the supercar will start from around $1.15 million.

Production of the Senna will be limited to 500 units, which is 125 more than the P1, which was built in 375 examples. According to McLaren, the entire production run is already sold out. The official debut will take place at the Geneva Motor Show in March 2018.

Competition

Finding competitors for the Senna is a difficult task. While there are plenty of powerful supercars out there, like the Ferrari 812 Superfast and the Bugatti Chiron, none are as capable at the track as the Senna. The Aston Martin Vulcan would have what it takes to give the McLaren a run for its money, but you can’t drive it on public roads. This leaves us with just two high-profile supercars that have yet to be launched for sale as of December 2017.

Aston Martin Valkyrie

Developed with input from Formula One genius Adrian Newey, the Valkyrie is as innovative as the Senna. It has aggressive aerodynamics, F1-inspired styling, and loads of unique features that you can’t see on other production cars. And it’s road legal. Wild-looking on the outside, the Valkyrie is very simple on the inside, where Aston Martin took the same no-nonsense approach as McLaren. This car is made almost entirely of carbon-fiber and, unlike the Senna, it’s being designed to deliver a 1:1 power-to-weight ratio. Specifics aren’t yet available, but it’s safe to assume that the Valkyrie will crank out more than 1,000 horsepower and hit 60 mph from a standing start in only 2.5 seconds. Power is supposed to come from a 6.5-liter V-12 engine, but it’s not yet known whether it will be part of a hybrid drivetrain or not. Production will be limited to "between 99 to 150 vehicles," including the prototypes and the 25 track-only cars, so it will be quite the rare gem. It will be more expensive than the McLaren too, as it will cost more than the Vulcan, which retails for a whopping $2.3 million.

Mercedes-AMG Concept One

AMG’s very first supercar project isn’t supposed to arrive until 2019, but we already know a few things about it. Styling-wise, the most noticeable thing about it is that it doesn’t look like a Mercedes. Second; it’s not as radical as the Senna and the Valkyrie, but this isn’t a bad thing if you like more subdued designs. Still, it’s supposed to have race-like aerodynamics and downforce for solid performance on the track. And yes, it will be road legal too. The interior follows the same "form follows function" ethos with a clutter-free dashboard and a simple center console. But unlike the competition, it has massive displays in the center stack and the instrument cluster. The steering wheel is a tad more complicated too. Just like the Senna and the Valkyrie, there’s carbon-fiber almost everywhere you look. Motivation comes from a Formula One drivetrain that combines a 1.6-liter V-6 with an electrically-boosted turbocharger and an electric motor connected to the crankshaft. Total system output is expected to exceed 1,000 horsepower. Unlike the competition, the Concept One will also be able to run on electricity alone, albeit for only 15 miles or so.

Conclusion

2019 McLaren Senna Exterior
- image 752222
Virtually no competition on the market

Although some performance ratings sit below previous supercars built by the British firm, the McLaren Senna is definitely the most radical supercar ever built. The aerodynamics seem to be out of this world, and the power-to-weight ratio is downright tremendous. To the extent that the Senna doesn’t need to be more powerful than its predecessor. Yeah, sure, I’m surprised that the Senna isn’t McLaren’s most powerful vehicle yet, but power isn’t always everything, especially in the case of cars that need to perform well on the track too. And the Senna was designed to do just that. It’s a race car that somehow is legal to use on public roads, and not many companies can do that. Yes, the Bugatti Chiron, for instance, is more powerful and has the higher top speed, but it simply sucks at the track. It wasn’t built to race, and it doesn’t have the ability to do so. As a race-ready vehicle for the road, the Senna is a unique car at this point, and the fact that it looks so radical only makes it that much better. Over to you, Ferrari.

A Tribute to Ayrton Senna

2019 McLaren Senna

The car is named after Ayrton Senna, one of the world's greatest Formula One drivers

The car is named after Ayrton Senna, one of the world’s greatest Formula One drivers. Senna raced Formula One cars for 11 years, six of which it spent with McLaren. The Brazilian joined McLaren in 1988, after four years with Toleman and Lotus, when the British firm was racing Honda engines. Senna went on to win his first championship with McLaren in 1988 while finishing the 1989 season in second position. Two more titles followed in 1990 and 1991, helping McLaren become one of the most prominent F1 constructors at the time. His 1992 season was less impressive with a fourth-place finish, while in 1993 he lost the championship to Alain Prost. In 1994, Senna made the switch to Williams. The Brazilian driver died following a crash at the San Marino Grand Prix, when his car left the racing line at nearly 200 mph, running into a concrete wall. McLaren has won a total of eight constructors’ championship between 1974 and 1998, four of them scored with Ayrton Senna in the team.

“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 honors 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," said Bruno Senna, racing driver and McLaren ambassador.

Press release

“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 P1™ 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 P1™; 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. 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 unmistakable. 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 P1™.

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 Zero™ 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.
