The Koenigsegg Sadair’s Spear is the Swedish hypercar maker’s most extreme track-focused machine yet — and yes, it’s still road-legal. Based on the Jesko, the Sadair’s Spear is lighter, more powerful, and pushes the limits of aero, tire tech, and chassis tuning. Limited to just 30 units, each costing around $5 million, it is named after the racehorse ridden by Christian von Koenigsegg’s father in his final race in 1976.
Drawing its DNA from the already formidable Jesko, the Sadair’s Spear takes performance and engineering to new heights, with a singular focus on lap times, driver engagement, and technological innovation.
Every element of the Sadair’s Spear is designed for maximum effect. The car is lighter than the Jesko thanks to extensive use of carbon fiber, titanium, and other exotic materials, resulting in a curb weight that pushes the boundaries for a road-going machine. The chassis has been reworked with a stiffer suspension setup, enhanced by advanced adaptive dampers and a track-oriented geometry that delivers razor-sharp handling and confidence at the limit.
Aerodynamics are at the heart of the Sadair’s Spear. The front end features larger bonnet vents and wider louvres over the front wheels to manage airflow and reduce lift. The splitter is not only dramatically enlarged but also actively adjusts to optimize downforce and balance through corners. The rear is dominated by a massive, active twin-blade wing—one of the largest ever fitted to a road car—which works in concert with the rear bodywork borrowed from the Jesko Absolut to minimize drag on straights and maximize grip in corners. Every surface and duct is sculpted for function, resulting in a car that sticks to the track with relentless force.
Under the rear deck sits Koenigsegg’s legendary 5.0-liter twin-turbo V8, a masterpiece of modern engineering. On standard 95-octane fuel, it produces 1,300 horsepower, but switch to E85 biofuel and output jumps to a staggering 1,625 horsepower. The engine revs freely to 8,500 rpm and is mated to Koenigsegg’s revolutionary Light Speed Transmission—a nine-speed, multi-clutch gearbox that can shift between any gear in just 0.2 seconds. The system eliminates the need for a flywheel, allowing for lightning-fast throttle response and a direct connection between the driver and the car’s immense power.
Performance figures are nothing short of breathtaking. The Sadair’s Spear is expected to accelerate from 0–62 mph in under 2.5 seconds, with a top speed well beyond 300 mph, though its true focus is lateral grip and lap times rather than outright straight-line speed. Advanced tire technology, developed in partnership with Michelin, ensures the car can exploit its downforce and power on both road and track.
Inside, the Sadair’s Spear is stripped-back but still luxurious, with exposed carbon, Alcantara, and minimalist controls. The cockpit is designed to keep the driver focused, with a digital display that provides real-time telemetry, lap timing, and performance data. Each of the 30 cars will be individually tailored to its owner, with options for bespoke paint, trim, and even aerodynamic setup.
The car’s name is a personal tribute: “Sadair” was the racehorse ridden by Christian von Koenigsegg’s father in his final race in 1976, symbolizing both speed and a pioneering spirit. With only 30 units to be built, each priced around $5 million, the Sadair’s Spear is set to become one of the most exclusive and sought-after hypercars in the world.
In interviews, Christian von Koenigsegg describes the Sadair’s Spear as the ultimate expression of his company’s philosophy: pushing the boundaries of what’s possible, blending extreme engineering with artistry, and delivering a car that is as thrilling on the racetrack as it is on the open road. For those lucky enough to own one, the Sadair’s Spear promises a driving experience unlike anything else—a true spearhead in the hypercar wars.
