The LaFerrari is a hybrid hypercar with an 800 horsepower 6.3-liter V12 engine, active aerodynamics, a seven-speed dual clutch transmission, carbon ceramic brakes and just about every other performance-enhancing piece of technology under the sun. For this reason it comes as little surprise that even the LaFerrari’s air intake system is a complicated piece of tech, as was recently outlined by YouTube’s Engineering Explained.
The LaFerrari features ‘Continuously Variable Length Intake Tracks’, which allows the car to continually adjust the length of the intake runners based on the engine speed. At low engine speeds longer runners are ideal as it makes the intake air more turbulent, thus resulting in a better air-fuel mixture and more efficient combustion. At higher RPMs shorter intake tracks allow the air to get into the engine faster and easier, allowing it to create more power. At certain engine speeds air may become trapped in front of the engine intake valve, with the variable tracts allowing for volumetric efficiency greater than 100%, resulting in what Engineering Explained calls a “light supercharging effect.”
For a much more clear explanation of the LaFerrari’s unique intake system, which was used on the road-car after it was banned from Formula 1, check out the video above.
