Very few associations can exhilarate and delight like the union between a naturally-aspirated V12 Ferrari engine and open-top motoring: the Ferrari 12Cilindri Spider. The concept giving shape to the Ferrari 12Cilindri Spider draws inspiration from open-topped Ferrari Gran Turismo models of the 1950s and ‘60s, which combined the unmatched performance of a road-going racing car with the unique opportunity to revel in the sound of the 12-cylinder engine with the roof down, and extraordinary long-distance driving comfort. The design of the car makes a break from the recent canons of the Ferrari two-seater Berlinetta spider genre, eschewing muscularity and sensuality in favor of a more futuristic language founded on formal purity with only the barest hint of a typically automotive visual lexicon.
Powertrain
The F140HD engine equipping the Ferrari 12Cilindri Spider is the new version of the iconic naturally-aspirated Ferrari V12, the purest expression of Ferrari’s soul: its peerless performance, powerful soundtrack and exclusivity make it the worthy heir to the legendary Berlinetta sports cars that wrote some of the most glittering chapters in the marque’s history. The engine can unleash up to 830 cv while its max revs have been increased to 9500 rpm thanks to the adoption of innovative solutions.
The engine features modified components and software, some of which were already adopted on the open-top special series 812 Competizione A, ensuring it tops its category in terms of performance. To allow the V12 to rev so high, the engineers worked to reduce the weight and inertia of the engine’s components, adopting titanium con rods, which guarantee a saving of 40% in rotating mass compared to steel with the same mechanical resistance. A different aluminum alloy was used for the pistons, making them lighter than on previous applications. Further weight reduction was gained by the adoption of a rebalanced crankshaft which is 3% lighter.
The valvetrain with sliding finger followers is derived from Ferrari’s unparalleled experience in Formula 1 and was developed specifically for the V12 with the aim of reducing mass and availing of more high-performance valve lift profiles. The sliding finger follower, which is steel with a Diamond-Like-Carbon (DLC) coating, transmits the action of the cam to the valve using a hydraulic tappet as the pivot for its movement. The use of DLC reduces the coefficient of friction at critical points, significantly improving the mechanical efficiency of the engine.
For the very first time on a naturally-aspirated engine, an innovative software strategy was developed that can modify the maximum torque available as a function of the gear selected. This gives the driver the feeling of smooth, progressive pick-up as the transmission ratio increases, another vital factor in making the driving exhilaration delivered by the Ferrari 12Cilindri Spider truly unique.
A crescendo of never-ending acceleration and power delivery has been a signature of all Ferrari V12s. Now innovative Aspirated Torque Shaping (ATS) has allowed Maranello engineers to sculpt the torque curve in third and fourth gears using sophisticated electronic control that improves perception of the torque without impinging on acceleration, all to the benefit of driving pleasure. The introduction of new gear ratios furthermore keeps acceleration levels high and allowed the engineers to define a new torque curve shape for an aspirated engine.
Optimizing the engine’s mechanical efficiency and that of the lubrication circuit is critical to reducing emissions and consumption. The calibration of the variable displacement oil pump allows the oil to circulate throughout the entire engine and then be recovered along with the vapors from the sump. A solenoid valve, controlled by the engine ECU, is used to control the pump’s displacement in terms of engine revs and pressure, delivering only the amount of oil required and thereby simultaneously saving a significant amount of energy. The new configuration of the oil tank and pump’s hydraulic circuit reduces losses to a minimum and optimizes functionality in all operating conditions.
The gasoline direct injection system (GDI at 350 bar) comprises two petrol pumps and four rails with pressure sensors that provide feedback to the pressure control system. The electronic injectors can also control up to three injections per engine cycle. The ignition system is managed by an ION control unit which has a single and a multi-spark function. This unit also serves a knock monitoring and control function, using a sophisticated strategy for recognizing the quality (octane rating) of the fuel in the tank to maximize the thermodynamic efficiency of the engine.
The new exhaust system, developed to allow the car to comply with the latest emissions requirements (EU6E, China 6b and Bin 50), introduces a ceramic catalytic converter coupled with a particulate filter. This is the most advanced emissions-reduction technology available and involved lengthy calibration of the software strategies.
The Ferrari 12Cilindri Spider sports the 8-speed DCT (Dual Clutch Transmission) that received such a unanimously rapturous welcome on other cars in the range, starting with the SF90 Stradale. Thanks in part to larger tyres on 21” rims, this solution delivers 5% shorter gear ratios in the lower gears and a 12% increase in torque at the wheels compared to previous V12 applications, all to the benefit of longitudinal performance under acceleration and gear shifting times (30% faster than the previous two-seat V12 applications).
Exterior
With the Ferrari 12Cilindri Spider, Flavio Manzoni and the Ferrari Styling Centre design team set out to radically transform the stylistic codes of Ferrari’s previous mid-front-engine V12s. The car in fact marks a clear departure from the sculptural language that characterized the 812 Competizione A, for example, instead favoring a more sophisticated language that still retains the necessary formal design rigor to achieve a sense of stylistic unity.
Clean lines dominate the car’s geometry, underscoring the volumes that make up a seamlessly interconnected whole. The ultra-clean flanks sweep back along the entire car from a dihedral section. Although retaining a signature Ferrari sensuality, the wings have been sculpted with extreme geometric precision: all the lines are the result of intersections between the volumes and a more functional approach to form has been taken that eschews nostalgia. The muscular rear wing is imposing, yet also perfectly controlled geometrically. On the front wing, that muscular tension extends slightly, coming to rest along the flank and further accentuating the car’s monolithic aesthetic.
The sculpted bonnet is extremely sleek and incorporates the front wings. Removing the cut lines from the wings gives a smooth, uninterrupted surface to the muscularity of the design, lending the entire bonnet a sense of ultra-clean fluidity, interrupted only by two vents to cool the engine bay. One of the objectives of the Ferrari 12Cilindri Spider was to explore design languages only tangentially related to the car world. The front has lost certain signature elements, such as the elongated form of the headlights and the traditional grille shape, in favour of geometries and intersections innate to the car’s design. The headlights are integrated into a single wraparound band from which the DRLs emerge like blades.
This car differs from the Ferrari 12Cilindri in the boldly expressive character created by the two buttresses at the rear, behind which an element with a black-screen effect is set. The crease lines evident on the buttresses clearly echo the motif of the flank, accentuating the expressiveness of the design of these elements. Set into the flank is a ‘quarterlight’ in back-painted polycarbonate.
Instead of adopting a rear spoiler, the designers have used two active flaps integrated with the rear screen, creating a signature delta theme. The overall perception is of a seamless whole, creating the idea of a very high-tech form. The development of this concept allowed the designers to treat the Ferrari 12Cilindri Spider’s cabin in a new way, tracing the frame of the surface in body color to echo the rear screen theme and integrate organically with the rest of the cabin which itself is characterized by a black screen effect.
Cockpit
The design of the Ferrari 12Cilindri Spider’s interior sees it split into three different levels: the first, dominated by the upper part of the dash, continues around to blend into the door panel trim. Next is the central area while the third includes the footwells and seats. Each level is clearly defined, heightening the dual-cockpit effect through the color and material combinations. These are used to create either an elegant or sporty look for the seats and other features. Ferrari’s signature luxury and performance are flanked on the Ferrari 12Cilindri Spider by a focus on environmental sustainability: extensive use has been made of sustainable materials such as Alcantara© containing 65% recycled polyester.
The interior style takes its inspiration from the Prancing Horse’s dual-cockpit architecture. In recent years, that layout was used for the Ferrari Roma and Roma Spider as well as the Ferrari Purosangue. The Ferrari 12Cilindri Spider’s cabin has an almost symmetrical structure comprising two modules for driver and passenger and offering an astonishing standard of comfort and involvement in the driving experience.
The dashboard extends horizontally, a fact underscored by a clear separation between the trimmed volumes in the upper section and the technical functions in the lower section. The upper section features two distinct binnacles dedicated to the driver and passenger instrumentation and to the climate control vents. A deftly elegant color and material change draws the eye to the two volumes separated by the body of the dash, which seem almost to float, further enhancing the feeling of lightness in this area.
The panels of the central tunnel extend outward from the dashboard geometries as if they were almost an extension of the latter. The trimmed area features a large sculptural gash emphasized by contrasting materials. The armrest is in the trimmed area of the tunnel and extends into the medallion area, revealing contrasting metallic edging that creates an elegant intersection between the volumes. The side section of the tunnel itself has been scooped out, again recreating that floating feeling. The structure of the tunnel is trimmed with exclusive upholstery, and features a Y-shaped metal element into which the iconic shift gate is set.
Unlike the Ferrari 12Cilindri, there is no rear bench as the rear zone of the cabin of the Ferrari 12Cilindri Spider is used to stow the retractable hard top. However, the solution chosen for the roof system still leaves plenty of space in the cabin, and the Ferrari 12Cilindri Spider is a versatile car suitable even for long journeys.
The Ferrari 12Cilindri Spider introduces a new Human Machine Interface (HMI) comprising three displays that raise the Ferrari V12 Berlinetta onboard experience to new heights. All of the main functions can be controlled from the central 10.25” touchscreen capacitive display within reach of both driver and passenger. This is flanked by a 15.6” driver display showing all of the driving and vehicle dynamics information. Lastly, the passenger is always completely involved in the driving experience thanks to an 8.8” display that ensures they feel like a genuine co-driver.
The car sports the capacitive steering wheel seen on all of the latest models in the range featuring the indented buttons for ease of use. This means that command activations are more precise, instant and intuitive even in sporty driving conditions. The Ferrari 12Cilindri Spider comes with Apple CarPlay® and Android Auto®-based mobile connectivity systems as standard, both easily controlled from the new central display. A wireless charging mat on the central tunnel (as standard) makes phone charging simple too.
Available as an optional on the Ferrari 12Cilindri Spider is the high-end audio system developed in collaboration with Burmester®, comprising 15 loudspeakers and unleashing a massive 1600 W for a genuinely unprecedented in-car experience at any volume and any speed. The high frequencies are crystal clear and sparkling, thanks to Ring Tweeter technology which minimizes distortion. The powerful dual coil subwoofer guarantees a wonderfully full, rich sound which, thanks to Ultraflat Headliners, is all part of a 360-degree listening experience.
Aero
The main objective of the Ferrari 12Cilindri Spider’s aerodynamics was to produce a sober, elegant car without compromising on performance. The 25-mm nolder on the boot lid and the active aero are the two signature elements of the tail section. The former guarantees the recompression required to maintain the car’s aero efficiency when drag is minimal while the flaps permit two different configurations, Low Drag (LD) and High Downforce (HD) respectively.
In the LD position, the flaps are flush with the bodywork so that the air runs over it uninterrupted, making them invisible to the flow. This configuration is retained until a speed of 60 km when downforce is not very relevant to the performance of the car, something that is also the case over 300 km/h. In between these two speeds, however, downforce plays a central role and the spoilers’ movement depends on the car’s longitudinal and lateral acceleration. In high downforce configuration, the Ferrari 12Cilindri Spider generates maximum downforce and guarantees that the car is aerodynamically balanced.
An internal aerodynamic passage has been created in the trim ahead of the buttresses. Its purpose is to enable the flow of air towards the rear of the car, facilitating recompression behind the adjustable rear screen and reducing the amount of air recirculating in the cockpit. The vertical profile on the outside of the aerodynamic passage has the task of correctly directing the air towards the rear, to the benefit of efficiency and flow stabilization.
The underbody is designed to maximize efficient vertical load generation, also by managing the airflow out of the central radiators. The planform and profile of the louvres in the central opening of the underbody minimize the impact of the hot air which is not highly energized. Two louvres have been created in the low-pressure area behind the front wheels which, by reducing overpressure inside the engine compartment, increase the efficiency of the radiating masses, lowering drag and increasing downforce generation.
As was the case with the 812 Competizione A, downforce on the front underbody is generated by three pairs of vortex generators optimized in the wind tunnel. The front underbody also contributes to brake cooling by delivering a flow of lower-temperature air from the front splitter.
The central underbody has been designed to correctly channel the air flows, retaining the available energy all the way to the rear diffuser. To that end, the transmission tunnel opening was reduced to balance the amount of air that would flow inside it. A raised section ahead of the rear wheel shields the tires and deflects the flow towards the rear.
The rear underbody sports a pair of vortex generators which are used to produce efficient downforce and channel the flows towards the extractor. In line with Ferrari’s philosophy of transferring innovations from the racing world to the road-going sports cars, the engineers designed an air inlet near the outer edge of the rear fence to provide ventilation for the silencer’s electronics.
Cooling
The heat dissipation requirements of the engine and ancillaries demanded a redesign of the car’s entire cooling system which resulted in front underbody evacuation being optimized, with no fewer than seven openings in the front bumper. In particular, the space between the longitudinal elements of the chassis houses the engine coolant radiator and air-con circuit condenser, which are fed by the central opening, while the oil radiator has been split into two separate elements, lying ahead of the front wheels. The side air intakes are divided in two: the outer part is designed to cool the engine oil radiator while the inner one cools the brakes.
A generous brake cooling duct is fed by two openings, one between the radiator intakes and the other on the lower part of the front splitter. The entire system is integral to the oil radiator intake to optimize the routing of the front brake intakes. The side intakes are framed by an L-shaped element designed to maximize the amount of air entering the opening whilst simultaneously correctly channeling the flow along the car’s flanks.
The air in the engine bay exits through two vents on the bonnet which reduce overpressure, improving cooling efficiency. Thanks to the latter, there are fewer openings on the underbody, thereby maximizing efficient downforce generation. On the wing behind the front wheels there is also a vent for the air from the wheelarch which minimizes overpressure on the underbody caused by the cooling duct for the brakes and front diffusers.
Vehicle Dynamics
The Ferrari 12Cilindri Spider boasts the very state of the art in front-engine Berlinetta dynamic controls. The introduction of brake-by-wire allowed the latest innovations from the range to be adopted, including ABS Evo that debuted on the 296 GTB and the 6D sensor that guarantees optimal precision to the Virtual Short Wheelbase (PCV) 3.0 and Side Slip Control (SSC) 8.0 systems, together with reduced braking distances and a more accurate repeatability of braking. The Aspirated Torque Shaping, an entirely new control logic, also emphasizes even further the smoothly linear power delivery from the legendary naturally-aspirated engine, thanks to electronic control.
The SSC 8.0, a new evolution of the famous Ferrari control unit, allows the systems to talk to each other using a shared language that calculates the optimal operating mode for each one in order to maximize the car’s overall performance. The SSC 8.0 integrates the Ferrari 12Cilindri Spider’s controllers and creates natural synergy with the new ABS Evo.
The SSC 8.0 is Ferrari’s proprietary system and has been optimized to further improve estimation accuracy and learning speed (+10% compared to previous applications), as well as control on very low grip surfaces. Grip estimation is flanked by the contribution of the grip recognition logic: by using the information from the EPS CPU and the side-slip angle estimated by the SSC 8.0, the Ferrari 12Cilindri Spider can estimate the tire-road grip level even when steering. Thanks to this approach, the grip can also be estimated in normal use conditions and not just on the limit, making it faster for the system to learn real grip levels.
The Ferrari 12Cilindri Spider features the four-wheel independent steering (4WS) that debuted on the special series 812 Competizione, which manages the movement of every wheel independently to improve yaw management in cornering and responsiveness during rapid direction changes. The rear-wheel steering has innovative mechanical characteristics that significantly improve precision of control of the position of each single actuator, giving faster axle response time and consequently improved responsiveness through corners. Optimum handling is also ensured thanks to a near-ideal weight distribution – 47.8% front and 52.2% rear – and the car’s responsiveness also benefits from the 20-mm reduction in the wheelbase compared to the 812 GTS.
Tires
The Ferrari 12Cilindri Spider can be fitted with Michelin Pilot Sport S5 or Goodyear Eagle F1 Supersport tires, both of which were developed in a new size for the Maranello company: 275/35ZR21 at the front and 315/35ZR21 at the rear. Development benefited from physical and virtual sessions, the latter carried out through simulator testing to reduce the number of physical prototypes and, consequently, development times and cycles.
Performance has been optimized thanks to the adoption of the latest technologies in terms of compounds, tread design concepts and casing characteristics. Extensive testing has led to improved performance, dry grip levels and balance, stability on the limit and in the wet, as well as improved comfort and noise characteristics both internally and externally, including a 10% reduction in rolling resistance compared to the previous Ferrari front-engine V12 Berlinetta applications.
Chassis
The Ferrari 12Cilindri Spider’s all-aluminum chassis, featuring a 20-mm reduction in wheelbase compared to the 812 GTS, is completely new: specific attention was focused on the geometry of cast components such as the shock towers and A and C pillars, to improve torsional rigidity whilst simultaneously reducing weight.
The result was an increase of 15% in torsional rigidity compared to the past, which ensures more predictable dynamic behavior, with consequent benefits for suspension precision. Thanks to more extensive use of castings, the number of extruded components requiring assembly has been significantly reduced, making the assembly process more efficient. Lightness was a key requisite throughout the entire development of the chassis and body-in-white of the Ferrari 12Cilindri Spider, which weighs just 60 kg more than the Ferrari 12Cilindri – a remarkably small weight increase made possible by the innovative solutions developed specifically for this car.
The body includes aluminum reinforcement connections between the roll bar behind the occupants and the B-pillar. This solution offered a significant saving in weight which, in turn, allowed for a lower center of gravity. Featuring a dual curvature above the heads of the driver and passenger for greater headroom, improving both comfort and versatility, the retractable hard top (RHT) takes just 14 seconds to open or close, and can be operated at speeds up to 45 km/h. The kinematic system moves with elegant harmony, while its simplicity, combined with the use of aluminum, makes this a much lighter option than other solutions. Completing the roof zone is a rear screen which can be electrically height-adjusted. This feature offers occupants extraordinary levels of comfort in the cabin when driving with the roof down, and even allows a normal conversation to be held at speeds up to and beyond 200 km/h.
For the first time on a Ferrari production car, a secondary alloy with 100% recycled material has been used to make the shock towers of the gearbox subframe: its introduction allows a reduction in carbon dioxide emissions of 146 kg of CO2 for every car produced. Thanks to an extensive development phase, it was possible to guarantee that the mechanical characteristics are the same as non-recycled alloy, exploiting the slight differences in chemical composition. For the validation of this new alloy, extensive testing was undertaken to assess the static and dynamic behavior of the components and ensure excellent results in fatigue and crash tests.
