Prior to the arrival of the Dino V6 with the 2.9-liter V8 models 308 and Mondial, Ferrari experimented with four-cylinder internal combustion engines. Designed by Aurelio Lampredi in the early 1950s, the Lampredi engine family went on to power the WSC, Formula Two, and Formula One racing cars.

Invented by Fabrizio Favaretto , the diagram shows a compressor that is mechanically independent of the turbocharger
The turbocharger is located in the exhaust duct and operates an electric generator, while the compressor is located in the intake duct and is operated by an electric motor. Why did Ferrari propose such a complex design?
According to the filing of the mark, the control method works "by establishing when the intensity of acoustic emission in the exhaust gases of the combustion engine internal must be increased, and reduce the mechanical power effectively absorbed by the electric generator compared to the available mechanical power to increase the intensity of acoustic emission in the exhaust gases of the internal combustion engine .
What this means, Ferrari reduces turbo lag while increasing exhaust noise to the driver's and pbaders-by's enjoyment: the turbocharger turbine wheel rotates faster in the duct exhaust, the more the exhaust pot is strong. both the electric motor and the electrically badisted compressor (supercharger) that forces air into the engine.
A 48 V four-cylinder hybrid engine to control the sound of the exhaust sound? It's something Enzo Ferrari would not have thought possible in his day. As for the possible applications, Alfa Romeo and the recovery of the Dino have the greatest chances.
