Only a few associations can exhilarate and delight just like the union between a naturally aspirated V12 Ferrari engine and open-top motoring. The Ferrari 12Cilindri Spider, unveiled at this time at an unique occasion hosted at Miami Seashore, fuses these two very particular sensations in a two-seater Berlinetta spider powered by Ferrari’s iconic twelve-cylinder engine. This iteration of the V12 delivers 830 CVs and retains revving proper as much as 9500 rpm, providing the driving force and passenger an much more unique open-air driving expertise.
The idea giving form to the Ferrari 12Cilindri Spider attracts inspiration from open-topped Ferrari Gran Turismo fashions of the Fifties and ’60s, which mixed the unequalled efficiency of a road-going racing automotive with the distinctive alternative to revel within the sound of the 12-cylinder engine with the roof down and extraordinary long-distance driving consolation. The design of the car makes a break from the latest canons of the Ferrari two-seater Berlinetta spider style, eschewing muscularity and sensuality in favour of a extra futuristic language based on formal purity with solely the barest trace of a sometimes automotive visible lexicon.
The Ferrari 12Cilindri Spider is meant for each connoisseurs of the marque with a transparent imaginative and prescient of what Ferrari has stood for within the motoring world since 1947 and newer Ferraristi who dream of a automotive that lets them mix unmatched driving thrills with consolation and Italian design—and the opportunity of having fun with the wind of their hair. This actually is a automotive for the few.
POWERTRAIN
The F140HD engine equipping the Ferrari 12Cilindri Spider is the brand new model of the long-lasting naturally-aspirated Ferrari V12, the purest expression of Ferrari’s soul. Its peerless efficiency, highly effective soundtrack, and exclusivity make it the worthy inheritor to the legendary Berlinetta sports activities vehicles that wrote a few of the most glittering chapters within the marque’s historical past. Due to the adoption of revolutionary options, the engine can unleash as much as 830 cvs, whereas its max revs have been elevated to 9500 rpm.
The engine options modified parts and software program, a few of which have been already adopted on the open-top particular sequence 812 Competizione A, guaranteeing it tops its class by way of efficiency. To permit the V12 to rev so excessive, the engineers decreased the burden and inertia of the engine’s parts, adopting titanium con rods, which assure a saving of 40% in rotating mass in comparison with metal with the identical mechanical resistance. A distinct aluminium alloy was used for the pistons, making them lighter than in earlier purposes. Additional weight discount was gained by adopting a rebalanced crankshaft, which is 3% lighter.
The valvetrain with sliding finger followers is derived from Ferrari’s unparalleled expertise in Formulation 1 and was developed particularly for the V12 to cut back mass and avail of extra high-performance valve carry profiles. The sliding finger follower, which is metal with a Diamond-Like-Carbon (DLC) coating, transmits the motion of the cam to the valve utilizing a hydraulic tappet because the pivot for its motion. Using DLC reduces the coefficient of friction at crucial factors, considerably enhancing the mechanical effectivity of the engine.
A lot of the modifications targeted on optimising torque supply in all working circumstances. The result’s an engine with an exhilaratingly easy, seamless response that delivers peak energy on the crimson line.
The structure of the manifold and plenum is now extra compact. Shortening the size of the tracts and optimising the cam profiles permits energy to be unleashed at excessive revs. A system of variable-geometry inlet tracts optimises the torque curve in any respect engine speeds, enabling the size of the consumption tract to be constantly diverse concerning the firing intervals of the engine to maximise the dynamic cost within the cylinder.
An revolutionary software program technique was developed for the primary time on a naturally aspirated engine to change the utmost torque accessible as a perform of the chosen gear. This offers the driving force the sensation of easy, progressive pick-up because the transmission ratio will increase, one other very important consider making the driving exhilaration delivered by the Ferrari 12Cilindri Spider genuinely distinctive.
A crescendo of endless acceleration and energy supply has been a signature of all Ferrari V12s. Now, revolutionary Aspirated Torque Shaping (ATS) has allowed Maranello engineers to sculpt the torque curve in third and fourth gears utilizing subtle digital management that improves the notion of the torque with out impinging on acceleration, all to the advantage of driving pleasure. Introducing new gear ratios retains acceleration ranges excessive and permits engineers to outline a brand new torque curve form for an aspirated engine.
Optimising the engine’s mechanical effectivity and the lubrication circuit is crucial to decreasing emissions and consumption. The calibration of the variable displacement oil pump permits the oil to flow into all through all the engine after which be recovered together with the vapours from the sump. A solenoid valve, managed by the engine ECU, controls the pump’s displacement by way of engine revs and stress, delivering solely the quantity of oil required and saving important vitality. The brand new configuration of the oil tank and pump’s hydraulic circuit reduces losses to a minimal and optimises performance in all working circumstances.
The gasoline direct injection system (GDI at 350 bar) includes two gasoline pumps and 4 rails with stress sensors that present suggestions to the stress management system. The digital injectors also can management as much as three injections per engine cycle. An ION management unit with single and multi-spark features manages the ignition system. This unit additionally serves a knock monitoring and management perform, utilizing a classy technique for recognising the gas high quality (octane ranking) within the tank to maximise the engine’s thermodynamic effectivity.
The brand new exhaust system, developed to permit the automotive to adjust to the most recent emissions necessities (EU6E, China 6b, and Bin 50), introduces a ceramic catalytic converter coupled with a particulate filter. That is probably the most superior emissions-reduction know-how accessible and includes prolonged calibration of the software program methods.
Sound is pivotal to marrying the consolation, luxurious, and exhilarating driving feelings typical of a Ferrari V12. To this finish, each ingredient of the consumption and exhaust strains was optimised. Equal-length exhaust tracts, the 6-in-1 manifold for each cylinder financial institution, and the revolutionary design of the central sections have resulted in Ferrari’s typical V12 howl, which includes all noble combustion orders. The right integration and calibration of excessive and low frequencies from the consumption and exhaust programs additionally affect the engine’s timbre. The ducts’ form and the silencer baffles’ inner fluid dynamics have been designed to cut back backpressure to a minimal, thereby enhancing energy supply. The geometry of the types and curves of the exhaust system was additionally perfected to ensure the purest notes of the signature Ferrari sound to the limiter.
The consumption tract was modified to ensure that the soundtrack within the cabin was additionally completely balanced. Altering the place of the resonators additionally modified the stress waves, leading to a richer vary, notably by way of the center frequencies. The result’s a cleaner, fuller sound in all driving circumstances, particularly in sportier conditions.
The Ferrari 12Cilindri Spider sports activities the 8-speed DCT (Twin Clutch Transmission) that acquired a unanimously rapturous welcome on different vehicles within the vary, beginning with the SF90 Stradale. Thanks partially to bigger tyres on 21″ rims, this answer delivers 5% shorter gear ratios within the decrease gears and a 12% enhance in torque on the wheels in comparison with earlier V12 purposes, all to the advantage of longitudinal efficiency underneath acceleration and kit shifting occasions (30% quicker than the final two-seat V12 purposes).
Efficiency underneath acceleration by way of the gears has been considerably improved, and the introduction of the eighth gear improves vary in motorway driving. Thus, the eight-speed DCT each improves effectivity and is extra participating in all gears.
