LaFerrari
Limited Edition Supercar
Press Release - March 2013
 
The LaFerrari represents Ferrari's most ambitious project yet to push the boundaries of technology on a road car, drawing together the finest expression of the marque's technical capabilities in both GT and Formula 1 engineering. It boasts the most extreme performance ever achieved by a Ferrari production car and features the most advanced and innovative technical solutions which will, in the future, filter down to the rest of the Ferrari range. With production limited to just 499 examples, LaFerrari continues Ferrari's tradition in building uncompromising performance cars for a small number of highly discerning clients.
 
Styling
 
The LaFerrari perfectly melds cutting-edge formal and aesthetic research and aerodynamic functionality, a result achieved by the synergies - from the start of the model's inception - between Ferrari's Styling Centre, headed by design chief Flavio Manzoni, and the engineering and development departments.
 
The LaFerrari's overall silhouette and proportions are the very natural product of its architecture and the layout of its hybrid running gear. The design is striking and innovative, yet its sleek profile remains true to Ferrari's classic mid-rear longitudinal V12 sports car archetype: the cabin and engine compartment volumes are contained within the wheelbase to achieve the best possible balance of its masses. Impressively, the addition of the HY-KERS system has not resulted in an increase in dimensions, but a better balance between the car's front and rear overhangs. Seen from the side the car has a sharp, downward-sloping nose and a very low bonnet which emphasises its muscular wheelarches.
 
 
Powertrain
 
The LaFerrari is the first ever car with hybrid technology to come out of Maranello. The 6262cc V12 produces 800 CV and the electric motor a further 12o kW (163 CV) for a total of over 960 CV. Thanks to the huge technological leap forward represented by the HY-KERS system, the LaFerrari is the most high performance and efficient Ferrari ever built.Making full use of Ferrari's F1 expertise with KERS systems which has been further developed for application to road cars, the HY-KERS guarantees maximum integration between the V12 and the electric motor, seamlessly blending extreme performance with maximum efficiency. The high levels of torque available at low revs from the electric motor allowed the engineers to optimise the internal combustion engine's performance at higher revs, thus providing unending power throughout the rev range and a maximum torque peak of over 900 Nm.
 
This solution has not involved any increase in the car's dimensions or its wheelbase and has, in fact, helped lower its centre of gravity. The F1 dual-clutch gearbox is coupled with the electric motor and an auxiliary electric motor replaces the traditional alternator, thus saving weight and reducing the overall dimensions of the packaging. In addition, the HY-KERS solution was designed from the outset to be flexible and modular to enable its evolution for application to other models in the range.
 
The electric motor was designed employing High Specific Power Density technology which enabled the engineers to drastically reduce weight and volume in relation to available torque. The result is performance figures that are comparable to those of the F1 car with the same torque density and the same efficiency (94%) or, in other words, very limited power dissipation.Battery size was an essential factor in optimising the HY-KERS' weight-power ratio with the aim being to maximise performance while reducing fuel consumption. The solution was an extremely complex system consisting of 120 cells assembled into eight 15-cell modules, with a power output that's the equivalent of 40 traditional batteries but weighing just 60 kg. The high-voltage batteries are actually assembled in-house by the Scuderia racing department. The batteries are charged in two different ways: under braking - even hard braking when the ABS intervenes, such as when driving on a track - and every time the V12 produces more torque than required, such as in cornering. In the latter instance, rather than the being sent to the wheels, the excess torque is converted to energy and stored in the batteries.
 
The HY-KERS system is governed by the Hybrid Power Unit which controls the power delivery from both the V12 and the electric motor via two inverters and two DC-DC converters. The variable-frequency control makes torque delivery rapid and precise.This technology has enabled Ferrari's engineers to maximise performance and reduce fuel consumption. C02 emissions have been reduced to 330 g/km without resorting to electric-only drive which was not within the mission of this model. The HY-KERS system is, however, designed so that in future applications a car can be driven using exclusively electric power for a few kilometres and, during development testing, a full-electric version of LaFerrari achieved just 220 g/km of C02 emissions on the combined cycle.
 
 
V12
 
The 6262 cc V12 is the most powerful naturally-aspirated engine ever used on Ferrari a road car. As well as producing 800 CV, the V12 spins to 9250 rpm which guarantees fantastic performance and driving pleasure as well as that unmistakable Ferrari V12 sound. These completely unprecedented results can be attributed to work carried out in three areas: volumetric, mechanical and combustion efficiency. To increase volumetric efficiency, the LaFerrari employs continuously variable-length intakes - a mainstay in F1 engine technology until rule changes banned its use which boost performance. As the length of the inlet tracts vary in line with engine speed, the torque and power curves are optimised across the rev range to suit the torque output of the electric motor.
 
Total torque generated by the V12 together with the electric motor is over 900 Nm, with the instantaneous torque from the electric motor being employed at lower revs and with the V12 engine power and torque optimised at higher revs. The V12's peak torque of 700 Nm is in fact developed at 6750 rpm. In addition the entire intake system from the dynamic air intakes on the top of the rear wheelarches to the intake plenum - was designed to maximise intake volume efficiency. The engine also boasts a very high 13.5:1 compression ratio for maximum combustion chamber efficiency.
 
Improvements in mechanical efficiency involved a number of components, most importantly the crankshaft which has been lightened and incorporates new, more aerodynamically efficient counter webs to reduce pumping losses. The crankshaft design also reduces masses around the rotation axis which cut overall mass by around 19 per cent.
 
Last but not least, one of the LaFerrari's signatures is its engine sound. Thanks to tuning of the exhaust in particular, the LaFerrari has an unmistakable Ferrari V12 soundtrack. The equal-length 6-into-1 exhaust system was hydroformed using Inconel as in F1 to help keep overall weight down with the additional benefit of very high temperature resistance characteristics.
 
 
Vehicle Dynamics
 
The LaFerrari is the first ever Ferrari to integrate the dynamic control systems with active aerodynamics and the hybrid system. Proprietary Ferrari algorithms govern all the systems so that the car can reach the most extreme limits of performance, aerodynamic efficiency and handling without any form of compromise in any area.
 
Thanks to myriad innovations across the board in its design and construction, the LaFerrari delivers absolutely exceptional performance, establishing itself as Ferrari's fastest-ever road car. The LaFerrari slashes more than 5 seconds off the Enzo's lap record at the Fiorano circuit. Such huge progress was made thanks to the hybrid technology and evolutions in traction and damping control, brakes and tyres. The integrated development of the entire car, particularly the tyres and suspension set-up, means that torque in the order of over 900 Nm can be fed through the wheels. Those levels of torque are produced by the combined effect of the V12 engine and the electric motor which provides instantaneous response at all times.
 
When the car is cornering, the HY-KERS keeps the V12's revs up to ensure quicker response times to the accelerator pedal and, when accelerating out of a bend, the traction control system constantly controls and distributes torque to the driven wheels thanks to the electronic differential, which maximises traction, and the stability control system, which monitors the car's reactions. When there is excess engine torque the HY-KERS diverts this to recharge the batteries and delivers extra torque to the wheels when required guaranteeing constant, blistering performance.
 
The brakes are equipped with new lightweight callipers, specifically designed to boost cooling, and new discs. This technology improves the friction of the braking surface of the discs and improves consistency and fade resistance with the result that longitudinal deceleration is improved by 15 per cent, with a 30 m reduction in stopping distances from 200 to 0 km/h. The braking system is completely integrated with all the other vehicle dynamics systems so that the hybrid system goes into regenerative braking mode which guarantees that the batteries are recharged even under very hard braking with the ABS active.
 
The levels of performance meant that Ferrari has gone for a very specific tyres et-up, with 265/30 R 19 Prelli P-Zeros on the front and 345/20 R 20s on the rear. Thanks to the integration of the dynamic control systems, the active aerodynamics and mechanical set-up, the response time to steering wheel inputs when turning into a corner is 30 per cent faster and lateral acceleration in corners increases by 20 per cent.
