Overview
Just as powerful as its track-focused sibling, the Jesko Absolut is the more seamless and stealthy of the two. Every surface element is constructed to reduce drag or surrounding turbulence while increasing high-speed stability.
With a drag coefficient value of only 0.278 Cd, a frontal area of just 1.88 m² and a massive 1600 horsepower, the Jesko Absolut is destined to achieve higher, more
extraordinary speeds than any Koenigsegg or any other fully homologated car before it. How fast? Time will tell. Looking at the math and our advanced simulations – it will be unbelievably fast.
Extreme performance
The Jesko Absolut is powered by a 1280 bhp (1600 bhp on E85), twin turbo charged V8 engine, featuring the world’s lightest V8 crankshaft, weighing just 12.5 kg. This flat-plane 180-degree crankshaft produces more power with greater efficiency while achieving a high 8500 rpm rev limit. Its design allows even firing across engine banks, creating a visceral engine sound. Koenigsegg has also designed super-light connecting rods and pistons to counter the tendency of greater vibrations in flat-plane engines.
Superior CFD
Koenigsegg’s CFD team went over every detail of the Jesko in a meticulous study in order to minimise drag. The most obvious change made was the removal of the Jesko Attack’s massive rear wing, which dropped downforce from 1400kg to 150kg. The target drag coefficient for the Jesko Absolut was 0.28Cd. Our CFD team overachieved, with a final figure of just 0.278 Cd.
Pressure Coefficient
While peak pressure occurs in the Jesko Absolut’s front radiator, the rest of the car has significantly reduced downforce. Modifications applied to the Jesko Absolut include more streamlined front splitter winglets, re-designed front louvers, an elongated tail, and the addition of aerodynamic, removable wheel covers. Every surface finish is intended to be as slick as possible, to allow air to glide effortlessly over the car.

Performance
REVOLUTIONARY TECHNOLOGY
The Koenigsegg Jesko features an all-new 9-speed, multi-clutch transmission – 100% designed and built in-house at Koenigsegg. The Light Speed Transmission (LST) represents a scale of evolution not seen since the development of modern dual-clutch technology at the turn of the century.
LST comprises nine forward gears and seven wet, multidisc clutches in a compact, ultra-light package. The LST is capable of upward and downward gear changes between gears at near light speed thanks to the simultaneous opening and closing of clutches that allow for totally seamless acceleration or deceleration.
That LST gear changes can occur in virtually zero time between adjacent gears is impressive. But what takes LST from impressive to evolutionary, however, is that these shift-time benefits apply when changing between ANY forward gears.
UPOD – ULTIMATE POWER ON DEMAND
The key to LST’s functionality is found in both the transmission’s unique design and Koenigsegg’s intelligent ‘UPOD’ technology – Ultimate Power On Demand. UPOD is the brain that instantly selects and engages optimum gearing for maximum acceleration.
While modern dual-clutch transmissions (DCT) enjoy millisecond shift times, they can only pre-select for a fast shift in one direction. DCT’s are designed to predict and pre-select the next gear based on inputs from the driver. If that prediction is wrong – e.g the driver wants to shift from 5th gear to 4th, instead of the presumed and pre-selected 6th gear – the driver will experience G-force losses and a slow shift response.
In addition, DCT’s only work in single-gear intervals. From 7th gear to 6th, to 5th, to 4th, for example. If the driver is in 7th gear and wants 4th for maximum power, the DCT cannot pre-select 4th gear directly. The driver has to pass through 6th and 5th gears, wasting time and power.
The Koenigsegg LST overcomes this via its unique multi-clutch design and UPOD technology, which selects the optimum gear for maximum power with a light speed gear change, regardless of whether that gear is 1, 2 or even 5 gears away.
UPOD uses vehicle speed and engine speed to determine the correct gear for maximum
power and directs the LST to engage that gear, no matter its relationship to the current gear. If you are in 7th gear and 4th is the optimal gear for maximum acceleration, UPOD can bypass downshifts to 6th and 5th gear and put the car directly from 7th to 4th – in light speed.
The effect is instant, prolific power that’s always optimised and always available, allowing maximum acceleration for overtaking, corner exits, and more.
AHEAD OF THE CURVE
Koenigsegg has a long history of developing innovative, in-house solutions aimed at optimizing vehicle performance. Near-enough is never good-enough. This no-compromise philosophy inspired the development of Aircore carbon fiber wheels, Koenigsegg Direct Drive, Triplex suspension geometry, the RocketCat catalytic converter, Autoskin technology, and much more. LST is the latest in a long line of Koenigsegg innovations.
Design
The Jesko Absolut is specifically designed for incredible speed. It boasts an aggressively sleek silhouette paired with insane powertrain engineering aimed at just one thing: groundbreaking top speed. The Jesko Absolut is unlike anything ever seen in a homologated, series production car.
Exterior
Added aeration means a cooler cylinder, cleaner combustion, and less strain on the engine at top power. The Jesko’s V8 is also fitted with the world’s first individual in-cylinder pressure sensor system for production cars, allowing the Engine Management System to operate each cylinder at maximum efficiency.
This mix of changes and technological improvements raises the engine’s rev limit to 8500 rpm – and increases the power to 1600 bhp on E85 fuel. When running on regular gasoline, the engine produces 1280 bhp. The Jesko Absolut features Koenigsegg’s most powerful engine, which is also the world’s fastest revving engine.
