Aerodynamics

Over 3000 hours have been invested in fluid dynamics (CFD) and aerodynamics analysis, alongside over 5000 hours of design and engineering for the Jesko Absolut on top of the Jesko. The CFD team meticulously went over every inch and design detail of the car, defining the elements needed to get to the drag coefficient even lower than the target of 0.28 Cd, to just 0.278 Cd.

Most obvious in the Jesko Absolut is the removal of the massive rear wing of the track version to take away the huge drag and downforce – dropping from 1400 kg of downforce on the track version to 150 kg on the Jesko Absolut. In place of a rear wing are two rear hood fins to maintain the stability of the car. The car is also more streamlined, reducing the high-pressure downforce zones that the track version has.

As seen on the aerodynamics diagram, the peak pressure area is in the front radiator, but the rest of the car has a significantly reduced downforce. More modifications were also done to the Jesko Absolut, such as more streamlined front splitter winglets, replacing its front louvers with smoother ones and the addition of removable wheel covers. Every surface finish is intended to be as slick as possible for air to glide effortlessly over.

The engineers and design team have worked hand in hand in order to achieve the low drag numbers while maintaining an iconic Koenigsegg visual imprint. The Jesko’s form and design have been reassessed with airflow and wind in mind for the Jesko Absolut. When looking at achieving even higher top speeds, the first consideration was to ensure as much straight-line flow as possible in the rear. That meant elongating the car more with a tear-drop shape. This extension in the aero-tail of the Jesko Absolut makes it 85 mm longer than Jesko and brings a completely new look to the rear of the car. “It was a great design opportunity to celebrate the visual lightness in the rear of the car”, says Marcello Raeli who was the lead designer on the Jesko Absolut project.

The design team and the engineers worked very efficiently around the aerodynamic requirements of the car – no more and no less to its exacting need for speed. Marcello sums things up for the Jesko Absolut well by saying that “as a result of removing these drag-causing elements and streamlining the new surfaces in the rear, the Jesko Absolut has a different profile”. He concludes that “the Jesko Absolut is seamless and sleek – almost like a land-based rocket”.The top speed of the Jesko Absolut will be extremely high. How high depends on the conditions and location of a possible high-speed run. If the opportunity arises the Jesko Absolut will be ready to take the crown. The name is self-explanatory – this is the fastest Koenigsegg that will ever be made – it is the Jesko Absolut.
