Ferrari: HY-KERS, high performance hybrid technology

The LaFerrari represents Ferrari’s most ambitious project 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.

Indeed, LaFerrari is the final outcome of this quest; it is the first ever car with hybrid technology to come out of Maranello. This model’s V12 combustion engine produces 800 hp and the electric motor a further 120 kW (163 hp) for a total of over 960 hp. Thanks to the technological leap represented by HY-KERS, a system designed based on F1 experience, the LaFerrari is the most high performance and efficient Ferrari ever built. Making full use of Ferrari’s time on the racetrack with the KERS system which has been further developed for application to road cars, the HY-KERS guarantees maximum integration between the V12 and the electric engine, blending the advantages offered by each of these two types of propulsion. The high levels of torque available at low revs from the electric engine allowed the engineers to optimize the internal combustion engine’s performance at higher revs, thus providing unending power throughout the rev range and an outstanding torque peak of over 900 Nm. In addition, the HY-KERS solution was designed from the outset to be flexible and modular to enable its application even in models with a different architecture. The HY-KERS system is governed by one a product developed in  cooperation  with  Ferrari's technical partner Magneti Marelli, the Hybrid Power Unit, which controls the power delivery from both the V12 and the electric engine.

This technology has enabled Ferrari’s engineers to maximize performance and reduce fuel consumption. “LaFerrari” emits just 330 g/km of CO2, but without resorting to electric-only drive, so that driving your Ferrari is still a pleasure. To design and create LaFerrari’s body, Ferrari drew heavily on the Scuderia’s F1 experience. As with all ultra high-power vehicles, for the  LaFerrari , too, the goal was to design a chassis which would provide maximum rigidity and minimum weight, despite the constraints imposed by incorporating the hybrid system. It was built entirely in-house in Maranello, using the same materials, structures and processes as the Scuderia. These uncompromising solutions guaranteed a significant improvement in performance characteristics over the chassis of the Enzo Ferrari, with torsional rigidity increased by 27%, while weight has dropped by 20% thanks to the use of composite materials.
