THIS THE MOST EFFECTIVE FERRARI? IF BEING Essentially the most powerful and fastest
road car ever built at Maranello makes that so, then, yes, the 740PS FIZ Berlinetta stands
above these. Greater mere replacement the 599 GTB Fiorano, this new leader of the pack laps Ferrari's Fiorano test track within a minute Z3 seconds - faster than every single other Ferrari production car until now. The 0-100 km/h time is merely 3. 1 seconds, but this is a number that will not tell the complete story. More telling is that the FIZ will reach zoo km/h in only 85 seconds and that its top speed is listed at 'over 340 km/h'.
Even this stupendous performance does not fully explain the notion of the newest ferrari front engined cars are often a comproise faet but practical cruisers the 599 erred more quietly ofoutright performance but with the f12 ferrari wanted to generate a car that has been dynamically on a similar level for some of its mid-engined v8s "it had to offer a fantastic feel whether driving to the supermarket or being hurled around a track. "the first question was if we'd the most effective architecture to achieve this at all or will have to put the engine in the straight back says technical director roberto fedeli "We did some testing with the 599XX and 599 GTO. We used the tyre dimensions, electronic controls, steering ratios, throttle, power and torque. Our conclusion was that folks couldn't evolve the 599 further, but if we're in a position to lower the centre of gravity, we're in a position to achieve the identical traits as our mid-engined V8s. " Whatever was something quite totally different from anything ferrari have built before.
"It can be carried out to have all those 730 horsepower down onto the road, " says fedeli; "and every driver is able to do it. " mechanical component, electronic computer programs and clever aerodynamics work hand-in-hand to deal with the FIZ'S extraordinary performance. We explain how. " Pre-production cars are hand-built in the 'Pilotino' area and within the bonnet of an almost-complete FI2 lies a 740 PS, 6, 262-CC 65-deg VI2 with two vivid red crinkle-finish cam covers. They truly are concealed by air-intake plenums that seem to stretch on once and for all to the depths of the engine bay. Facing everybody, an extension enhances torque and resonance to the induction note. Even though sharing the identical bore and stroke, with the FF engine, this dry-sump VI2, says Roberto Fedeli, "is no evolution from the parts perspective. Considering that the engine must sit significantly less than in the other fronr-engined cars, underneath end has to be brand-new. "
The cylinder head has been re-worked with re-designed combustion chambers, a really high compression ratio of 13. 5: 1 and new camshafts to offer the complete traits that Fedeli and his team desired. The engine is fed by high-pressure direct fuel injection, the petrol delivered at a massive 200 bar. Regardless of larger capacity of the naturally aspirated VI2, the proper execution of the torque curve (peaking at 689 Nm) is related to a Ferrari V8's. And though 80 per cent of the maximum torque can be had from 2, 500 revolutions for each minute, the top is saved until last. "We wanted to keep consitently the maximum power and torque at high revs. To help you to feel exhilaration, you need to raise the acceleration considering that the revs climb, " explains Fedeli.
In your day, engines like this were called 'carnmy', a reliable build of power that's accompanied by a huge rush considering that the engine comes fully on song. "This is one of the a few most crucial features you want from the sports vehicle, " the technical director continues. "For sure, the absolute most power and torque matters, though the kind of the capability and torque curves will be more needed for us. " The engine has been tuned so there is no discernible power drop at maximum RPM, because, adds Fedeli, "one thing our test drivers request in a Sports vehicle is that the engine must never end". The VI2 is powerful, but highly efficient, returning eight kilometres per litre on the combined cycle (a 30 % improvement within the 599) with C02 emission of 350 g/km.
A dual-mass flywheel helps protect the cabin from vibration and essentially the same FI dual-clutch trans-axle gearbox employed in the California and FF is found at the rear, configured for the FI2 with a specific band of gear ratios. The electronic E-Diff 3 varies its influence to get the capacity to the floor. When Ferrari design a whole new car, they will not simply brainstorm new a few ideas and bolt them together. "Our innovation activities are continuous, " explains Fedeli. "We develop a few ideas and store them away, proper we're making a new car we find the ones you want. " The Aero Bridge (see I, above) is a definite idea. At over 322 km/h, insufficient downforce or, worse, lift isn't conducive to a secure future for the driver. To combat this, the Aero Bridge kills lift as speed increases, with high stress on the FI2' s nose creating downforce. Wheels and the cut-outs of the wheel-arches can be a major method of getting drag which means Aero Bridge also fulfils an additional role, air spilling down sculpted channels in the wings to make a slippery curtain of air within a corner wheel-arches.
The result is just a body-shell that generates 123 kg of downforce at 200 km/h (up 76 per cent) and possesses a Cd of 0. 299 "It's a fantastic compromise between downforce and drag, " says the technical director. Downforce is way better addressed on the underbody, where any work won't affect Pininfarina's styling, "but if you possibly could also focus together with the human body, in that case your efficiency increases, " he adds. Ducts are necessary to cool the massive Brembo brakes, but are, literally, a real drag.
Active Brake Cooling (2) comprises shutters to offer a smooth face to the airflow, opening as long as needed. Activating them does not be determined by anything so crude as a thermostat to relay the fact the brakes are getting to be hot. Alternatively, Ferrari have evolved a mathematical model that 'knows' what precisely you doing by monitoring a massive selection of data, including speed, acceleration, braking, g-force, throttle use etc. So, without enjoying a single direct measurement, the management system knows what temperature the brakes could have reached when to open the ducts. A smooth under-tray reduces drag and lift at the rear is controlled by an evolution of the diffuser (3) that first appeared on the 1994 Ferrari F355.
