Introducing Jesko Sadair’s Spear: A Track-Focused, Road-Legal 1625hp Megacar
Ängelholm, Sweden
Koenigsegg has unveiled the Jesko Sadair’s Spear, a track-focused version of their iconic hypercar. The car has a large lightweight, top-mounted active rear wing, more horsepower, new turbine-blade carbon wheels, and a custom interior with racing seats and harnesses. Best of all? It’s road legal.
The name Sadair’s Spear is deeply personal to the family of founder Christian von Koenigsegg. His father, Jesko, after whom the hypercar is named, was a “passionate gentleman jockey” with deep ties to the equestrian community in Sweden. Jesko’s favourite race horse, which he rode on his final race back in 1976, was named Sadair’s Spear. Fittingly, Sadair’s Spear will finish off the production run of the Jesko and will begin deliveries in 2026: fifty years after Jesko and his horse ran their final race.
Given its track focus, Koenigsegg’s team of computational fluid dynamics (CFD) engineers worked to optimize airflow around the car. Stripping away the new aerodynamic features, Sadair’s Spear looks very reminiscent of the Jesko Absolut. It has the same elongated rear that gives the Absolut the lowest-possible drag coefficient for maximum speed.
Building on this base, Koenigsegg’s engineers have added large front canards, wheel-arch louvres, and a reengineered hood vent. As mentioned, the rear has received an active top-mounted double bladed wing as well as expanded rear hood intake scoops to maximize airflow to the engine. Koenigsegg projects that this enhanced airflow and cooling, coupled with an engine calibration update, will give Sadair’s Spear a maximum output of 1,625 horsepower on E85 biofuel - a 25hp increase over the Jesko Absolut.
Sadair’s Spear retains the twin-turbocharged V8 engine found in the other Jeskos, as well as the flywheel-free Light Speed Transmission (LST) capable of revving at 46,000 rpm/s. New for this car, gear changes through the LST are exclusively done through steering wheel-mounted paddle shifters, as is common with track-focused vehicles. Its immense power, combined with the new aerodynamics, make Sadair’s Spear ridiculously quick around a track. In initial testing, the car smashed the Gotland Ring record, previously set by the Jesko Attack, by 1.1 seconds.
“Sadair’s Spear represents a natural progression for Koenigsegg—an impeccable balance of raw power, refined aerodynamics, and extraordinary road presence. This car is destined to set records. Achieving such track dominance in a fully road-legal vehicle is nothing short of remarkable.” - Christian von Koenigsegg
According to Koenigsegg’s development test driver Markus Lundh, Sadair’s Spear has remarkable stability, especially at high speed, which he says is the biggest differentiating factor between Koenigseggs and their competitors in the hypercar space. The car is planted and nimble, cornering nicely thanks to an upgraded suspension with the front Triplex damper and Active Ride Height system, upgraded multi-layer carbon-ceramic brakes, and wider track-oriented tires.
“Celebrating a decade since the groundbreaking Koenigsegg One:1, Sadair’s Spear pushes the power-to-weight boundary even further, dropping around 35 kg of weight to achieve an extraordinary ratio, even surpassing the iconic 1:1 benchmark.”
Sadair’s Spear introduces new seven-spoke turbine-blade AirCore carbon fibre wheels, which somewhat pay homage to the iconic vortex-generating rims (VGRs) found on the Agera. These wheels are lightweight and incredibly strong, with each one being machined out of a single piece of carbon. They have built-in heat shielding to protect the carbon fibre from the immense brake heat and, of course, wear Michelin Pilot Sport Cup 2R tires.
The interior has a minimalist redesign, as one might expect in a stripped-down track-focused car.
Though there are new carbon racing seats and an optional six-point harness, the creature comforts that make the Jesko so usable remain: the steering-mounted SmartCluster display, USB connectivity, climate controls, inductive phone charging, Autoskin, and birds-eye parking assist. The car can even receive over-the-air software updates from Koenigsegg as the company tweaks and refines the car for maximum enjoyment.
Jesko Sadair’s Spear is the ultimate evolution of Koenigsegg’s iconic megacar. That doesn’t come cheap, though. Sadair’s Spear is priced at $3.8 million for 30 units, all of which were sold out long ago. Deliveries are set to begin in 2026, with these units following the 125 unit ‘standard’ Jesko production.
