Page 1 of 3 Next >>  There has been a single leitmotif that has been thrilling Prancing Horse enthusiasts since 1947: the naturally-aspirated, mid-front-mounted V12, the very first Ferrari engine to roar its way through the factory gates in Maranello. Unveiled today to public and media against the spectacular backdrop of Miami Beach in celebration of the 70th anniversary of Ferrari’s arrival on the American market, the Ferrari 12Cilindri is the natural evolution of the company’s uncompromising powertrain philosophy, which over the decades has continued to develop without ever straying from its original DNA and the marque’s core values.The Ferrari 12Cilindri is inspired by the legendary Grand Tourers of the 1950s and ‘60s, embodying the front-mounted Ferrari V12 two-seater mission with its effortless combination of elegance, versatility, and performance. The car represents the latest evolution in this bloodline and continues that unique legacy, elevating it towards new standards in performance, comfort, and design. Its silhouette exudes sportiness and class: simple yet harmonious lines feature an integrated active aerodynamic device to guarantee peerless performance, a front-hinged bonnet that exalts the view of the engine bay, and the two twin tailpipes that have become a signature of Ferrari’s 12-cylinder cars. The Ferrari 12Cilindri’s engine is the latest development of the iconic V12 that laid the foundations for the Maranello legend, in this version unleashing 830 cv and with maximum revs rising to a heady 9500 rpm. The impressive power curve ensures 80% of total torque is already available at just 2500 rpm, resulting in instantaneous pick-up for maximum accelerator response and a feeling of never-ending power all the way to the red line. The Ferrari 12Cilindri’s cockpit guarantees superb comfort for both driver and passenger, even on long journeys: its feeling of airiness and space is heightened still further by a glass roof, prestigious materials and a central display in addition to one for the driver and a third ahead of the passenger. The Ferrari 12Cilindri is aimed at driving enthusiasts, but also at those who demand new standards of performance, comfort and design: long-standing Ferraristi, loyal to the unique emotions that only the Ferrari V12 can deliver, as well as new clients dreaming of combining comfort and Italian design with exhilarating driving pleasure. The Ferrari 12Cilindri is designed for connoisseurs with a very clear vision of what Ferrari’s DNA has always been, truly making it a car for the few. The F140HD engine equipping the Ferrari 12Cilindri 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 by adopting challenging and innovative solutions. The engine features modified components and software, some of which were already adopted on the special series 812 Competizione, 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 aluminium 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 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. Most of the modifications focused on optimising torque delivery in all operating conditions. The result is an engine with exhilaratingly smooth, seamless response, that delivers peak power at the red line. The manifold and the plenum layout is now very compact: shortening the length of the tracts and optimising the cam profiles allows power to be unleashed at high revs, while the torque curve is optimised at all engine speeds by a system of variable geometry inlet tracts which enables the length of the intake tract to be continuously varied to maximise the dynamic charge in the cylinder. 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 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. Optimising the engine’s mechanical efficiency and that of the lubrication circuit is critical to delivering blistering performance and low fuel 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 vapours from the sump. A solenoid valve, controlled by the engine ECU in a closed loop, 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 optimises 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 constantly monitored by the engine control unit which has a single and a multi-spark function. The ECU also controls combustion in the chamber to ensure that the engine is always working in peak thermodynamic efficiency conditions, using a sophisticated strategy that recognises the octane rating of the fuel in the tank to avoid knocking. 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. Sound is pivotal to marrying the comfort, luxury and exhilarating driving emotions typical of a Ferrari V12: to this end, every element of the intake and exhaust lines were optimised. Equal-length exhaust tracts, the 6-in-1 manifold for every cylinder bank and the innovative design of the central sections has resulted in Ferrari’s typical V12 howl that comprises all of the noble combustion orders. The perfect integration and calibration of high and low frequencies coming from the intake and exhaust systems respectively also influence the engine’s timbre. The shape of the ducts and the internal fluidynamics of the silencer baffles have been designed to reduce backpressure to a minimum thereby improving power delivery. The geometry of the forms and curves of the exhaust system was also perfected to guarantee the very purest notes of the signature Ferrari sound all the way to the limiter. To guarantee that the soundtrack in the cabin is perfectly balanced, the intake tract was modified: modifying the position of the resonators also changed the pressure waves resulting in a richer range, particularly in terms of the middle frequencies. The result is a cleaner, more full sound in the cabin in all driving conditions, but especially in sportier situations. The Ferrari 12Cilindri sports the 8-speed DCT (Dual Clutch Transmission) that received such an 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 V12 berlinetta applications). Performance under acceleration through the gears has been significantly improved and the introduction of the 8th gear improves range in motorway driving. The eight-speed DCT thus both improves efficiency and is more engaging in all gears. Page 1 of 3 Next >> |
