Named after a father · Built to be the fastest
Geneva International Motor Show, March 2019 — the global debut of the Jesko.
The name honours Christian von Koenigsegg's father, a gentleman jockey with lifelong ties to Sweden's equestrian community.125 units in total, built at 40–50 per year and delivered from June 2023; in 2022, BBC Top Gear named the Jesko "Hypercar of the Year".
It is the complete expression of Koenigsegg's engineering idea: a twin-turbo V8 carried to an 8,500 rpm redline, a Light Speed Transmission that jumps directly between gears, and two approaches built on one chassis — the Attack, engineered for cornering, and the Absolut, engineered for top speed.
The HeartTwin-Turbo V8
A 5.0-litre twin-turbo V8, all-aluminium, 189 kilograms dry, delivered to an 8,500 rpm redline.
An engine engineered for instant response
Displacement 5,065 cc, bore and stroke of 92 × 95.25 mm, compression ratio 8.6:1. Twin turbochargers ride on ceramic ball bearings; beneath the car, a 20-litre carbon fibre air tank is pre-pressurised by an electric compressor, bringing the turbos to life before exhaust energy arrives — turbo lag, systematically eliminated.
- Boost1.7 bar (petrol) / 2.2 bar (E85)
- Pre-charge20L carbon-fibre tank · electric compressor
- Fuel1,280 hp on petrol / 1,600 hp on E85
- Torque1,000 Nm (petrol) · 1,500 Nm (E85)
Pre-charged intake
The instant the throttle opens, pressurised air reaches the intake side — the turbos are already at work before exhaust energy arrives.
Fuel as a tuning parameter
The same unit produces 1,280 hp on petrol and 1,600 hp on E85 — the choice of fuel is itself the calibration.
The intelligent cockpit
The SmartCluster instrument turns with the wheel so information always faces the driver — an ethos of restraint carried through the range since the first pre-series car of 2021.
Light Speed TransmissionNine speeds. Direct jumps.
A nine-speed multi-clutch unit, 90 kilograms, leaping directly between any two gears.
A conventional gearbox shifts sequentially. The LST goes straight to the gear you need.
The nine-speed multi-clutch layout weighs 90 kilograms complete. When the demand appears, UPOD (Ultimate Power on Demand) moves instantly from the current gear to the target — for example, directly from 9th to 4th — completing each shift in 20 to 30 milliseconds. Whether cruising on one gear or accelerating flat out, the LST changes gear only when it is genuinely necessary.

Shift durationBetween any gears
Forward gearsNo sequential shifting
"Because of its seamless shifting, whether up or down, everything just happens much faster. There are no delays — it behaves exactly the way you would want it to."
Jesko AttackKing of Downforce
The wing stays. An active, twin-profile element turns moving air into downward grip.
1:24.86 — the lap-time answer for homologated cars
On August 18, 2024, the Jesko Attack set a lap record for homologated production cars at WeatherTech Raceway Laguna Seca: 1 minute 24.86 seconds. Neither the car nor test driver Markus Lundh had visited this circuit — famous for the Corkscrew and its dramatic elevation changes — before the run.

Active twin-profile rear wing
The element adjusts its angle of attack continuously with speed and attitude — downforce generated on demand, with no drag wasted.
A complete aerodynamic suite
The front splitter, underbody flaps and side winglets work in concert, managing airflow and turning it into usable vertical load.
Suspension & braking
Triplex dampers front and rear control pitch; 410 mm front and 395 mm rear carbon-ceramic brakes provide sustained, dependable deceleration.
Night roads: downforce proven in daily use
Every steering input in the corner is carried precisely by the car's aerodynamic load.
One chassis. Two definitions of fast.
An aerodynamic layout built for corners: generating as much immediately usable, always-controllable vertical load as possible.

Same Heart · Two Directions
Jesko AbsolutLowest of Drag
No wing, no splitter; the tail extended by 85 mm. Zero-downforce direction, aimed at 500 km/h.
The wingless silhouette
The rear wing is removed entirely and the front splitter with it; the tail stretches 85 mm longer — the body becomes one continuous surface aimed at top speed.
Rigorous symmetry
From above, the car mirrors itself on the centre line; the Tang Orange stripe down the graphite body carries the colour language of the CCR era.
Precision in the hangar
Born in Ängelholm's retired fighter-jet hangar, 3,000 hours of aerodynamic computation and 5,000 hours of design converge on a drag coefficient of 0.278.
Every intake has its reason
Limited, precisely targeted vents release high-pressure air; streamlined rear wheel covers keep the flow attached to the body.
The tail: an art of stability
Rear-hood fins manage turbulence; the dished rear wheels keep rotating air away from the body. High-speed stability begins here.
A transformation: from Attack to Absolut
The same chassis — with the wing raised, it is built for downforce; with the wing retracted, the whole car commits to top speed. Two approaches, resolved in a single silhouette.
"We spent thousands of hours in CFD calculations — streamlining this car not just from an aerodynamic and design perspective, but from a high-speed stability perspective. The result is a phenomenally low drag of only 0.278 Cd."
Records in a straight lineAbsolut Overdrive
Örebro airfield · rear-wheel-drive combustion · against the all-wheel-drive electrics.
0–400–0 KM/H IN 25.21 SECONDS
The world record for homologated road cars — achieved with an entirely new software strategy on the very same Jesko Absolut as the 2024 record. The upgrade is named "Absolut Overdrive" and will be rolled out to every customer car.
Rear-wheel-drive combustion, rewriting the laws of physics.
In June 2024, at the same airfield, the Jesko Absolut first broke the record at 27.83 seconds; in August 2025 it was lowered to 25.21 seconds — both runs driven by Markus Lundh. The Light Speed Transmission, shifting in just 20 to 30 milliseconds, stands among the most important foundations of this result.
"That we achieve this level of performance with a production car utilizing a combustion engine with rear wheel drive only – beating all 4-wheel drive electric cars in a straight line is almost magical and shows that 'truths' can be re-written."
Sadair's SpearThe Final Racehorse
In 1976, old Jesko rode his favourite horse in his final race. Fifty years on, the horse's name became a new banner.
A name that crosses two generations.
Jesko von Koenigsegg was a gentleman jockey devoted to Sweden's equestrian community. In his final race, in 1976, he rode a horse named Sadair's Spear. On June 25, 2025, that name was given to the most track-focused car in the company's history: more power, less weight, a track-oriented cockpit, upgraded brakes and suspension, finely tuned aerodynamics — while remaining fully road legal in every global market.

Laguna Seca: 1 minute 24.16 seconds
On November 4, 2025, on the circuit where the Attack set its record, Sadair's Spear took the homologated-car benchmark further: 1 minute 24.16 seconds, verified by Racelogic. A strict 90 dB noise limit was in force that day, answered by fitting a heavy auxiliary muffler behind the rear — the record fell carrying ballast bolted to its tail.

"We knew that the Sadair's Spear had the potential to beat the lap record. To achieve this feat with the added muffler behind the car shows the potential for even greater performance on a less noise-restricted day."
