OVERVIEW

Unveiling of the Koenigsegg Jesko Absolut. It is the fastest Koenigsegg that the firm has ever produced, and it will never try to manufacture a faster series-production road car. Customers will have a choice between the Jesko Absolut and the Jesko version which is more track-oriented and was introduced a year ago.

Every surface of the Jesko Absolut has been specifically designed to increase high-speed stability while lowering drag and surrounding turbulence. The Jesko Absolute, albeit equally potent, is a smoother and more covert rendition of the Jesko.

Only 0.278 Cd is the drag coefficient for the Jesko Absolut. The Jesko Absolute is meant to reach higher, more exceptional speeds than any Koenigsegg or other completely homologated automobile before it thanks to its low drag, the frontal area of 1.88 m2, the power output of at least 1600 horsepower, and other design features.

Design

The Jesko Absolut was a rigorous exercise in removing all drag-causing features from the car's surfaces while also expanding back volumes to optimize airflow. In addition to more than 5000 hours of design and engineering for the Jesko Absolut on top of the Jesko, over 3000 hours have been spent on fluid dynamics (CFD) and aerodynamics studies.

The CFD team carefully examined every square inch and design feature of the vehicle, identifying the components required to reduce the drag coefficient from the desired 0.28 Cd to just 0.278 Cd.

The enormous rear wing that was removed from the Jesko Absolut is the thing that stands out the most. The wing is taken off to lessen drag and downforce, which reduces downforce from 1400 kg to 150 kg.

The Jesko Absolut form was reevaluated with a focus on low drag. This required lengthening the vehicle to give it a more teardrop-shaped appearance. The Jesko Absolut is 85 mm longer in the rear than the track-oriented Jesko, and the dished rear wheels completely alter the way it looks.

The Lightest V8 Crankshaft in the World

The 1280 horsepower (1600 bhp on E85), twin-turbocharged V8 engine that powers both the Jesko (track-oriented variant) and the Jesko Absolute (high-speed version) is the lightest V8 crankshaft in the world, weighing just 12.5 kg.

With a higher 8500 rpm rev limit, this new flat-plane 180-degree crankshaft generates more power. The flat-plane construction enables even firing throughout engine banks, resulting in a powerful, visceral engine sound. Dr. Thomas Johansson, the engine designer for Koenigsegg, has also created extremely light connecting rods and pistons to combat the tendency of higher vibrations in flat-plane engines.

Light Speed Transmission(LST) 

Since the advent of contemporary dual-clutch technology (DCT) around the turn of the century, evolution on the scale represented by the Koenigsegg Light Speed Transmission (LST) has not been as rapid.

The LST gearbox from Koenigsegg features nine forward speeds and several wet, multi-disc clutches in a small, extremely light package. It can shift into and out of any gear at nearly the speed of light. This is made possible by clutches that open and close simultaneously, creating a driving sensation that makes the relationship between the driver and the vehicle seem symbiotic.

Both the LST's size and weight are ground-breaking. The nine-speed Koenigsegg LST transmission weighs under 90 kg when all fluids are included, compared to modern high-performance DCTs that can easily weigh well over 120 kg.

In addition, the packaging is 50% smaller than prior Koenigsegg transmissions. The weight distribution and handling of the car are improved by keeping the weight in the center of the vehicle.

Nevertheless, the fact that these shift-time advantages apply when switching between ANY forward gears elevates LST from impressive to evolutionary.

Handling

When compared to the conventional road car, Koenigsegg's front and rear wishbones are the longest in the industry. A superior combination of responsiveness and stability is offered by big wheel bearings in light housing.

The Jesko's adjustable dampers are made by Swedish experts at hlins and then specially designed at the Koenigsegg facility in ngelholm with active control electronics. The driver has access to suspension management modes, and the dampers can be adjusted for bump and rebound damping, as well as spring ratio and ride height.

The suspension system on the Jesko Absolute has been modified to be more suited to extremely high speeds and less downforce. Since the front triplex system and hood air dam are required for the Absolut, they are both deleted.

The Absolut now has the option of a larger front luggage area thanks to these improvements. Like on earlier Koenigsegg models, the roof may be stored there, and the softer suspension provides a more comfortable ride in addition to freeing up luggage space.

Both Jesko variations extensively draw on the heritage of earlier world-record-setting Koenigsegg vehicles. For many years to come, their mix of strength, aerodynamics, chassis dynamics, and advanced technology will set new benchmarks in the mega car business.

The Jesko Absolut has a very high peak speed. Depending on the environment and the location of a potential high-speed run, how high. Regardless of who is now in charge, Jesko Absolut will be prepared to seize the crown if the chance arrives.
