The LaFerrari Aperta’s powertrain, which is the same as the LaFerrari’s, uses hybrid technology. It couples an 800 CV 6262cc V12 with a 120 kW (163 CV) electric motor for a total output of over 960 CV.
Thanks to the HY-KERS system, it is the most high performance and efficient Ferrari ever built. Making full use of Ferrari’s F1 expertise with KERS systems further evolved for use on road cars, the HY-KERS guarantees perfect integration of the V12 and the electric motor, seamlessly blending the advantages of both. 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 exceptional, continuous power throughout the rev range and a maximum torque peak of 900 Nm.
Coupled with the F1 DCT, 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 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.
The 6,262 cc V12 is the most powerful naturally aspirated engine ever sported by a road-going Ferrari. It punches out 800 hp and spins to 9,250 rpm, to deliver absolutely extraordinary performance, fun behind the wheel and an unmistakable Ferrari sound. These unprecedented results are the product of meticulous honing of the engine’s volumetric, mechanical and combustion efficiency. To boost volumetric efficiency, the V12 employs continuously variable-length intakes - a mainstay in F1 engine technology until banned by rule changes – which optimise performance as a function of engine speed. Similarly, the torque and power curves are optimised across the rev range. The hybrid powertrain generates total torque in excess of 900 Nm: the instantaneous torque from the electric motor is employed at lower revs and V12 engine power and torque is optimised at higher revs.
The V12’s peak torque of 700 Nm is, in fact, developed at 6,750 rpm.
