In a dramatic nod to Koenigsegg’s deep-rooted legacy, the Swedish hypercar marque unveils its latest creation—Sadair’s Spear.

Named after Jesko von Koenigsegg’s favourite racehorse, which he rode in his final equestrian event in 1976, this new machine stands as a personal tribute and a performance evolution unlike any other.

Designed for unrelenting track domination while remaining fully road-legal, Sadair’s Spear represents the zenith of engineering finesse and raw potency.

Performance Born of Air and Fire

The car receives an aerodynamic overhaul, beginning with a top-mounted double-blade active rear wing—purpose-built for superior downforce and track precision.

Complemented by elongated rear-end shaping, expanded front canards, a revised hood vent with a Gurney flap, and reengineered louvres, Sadair’s Spear slices the air with minimal drag and maximum cooling.

Koenigsegg’s advanced CFD team has optimized the airflow to extremes.

Rear hood scoops feed the engine at high speeds, while underfloor strakes, wheel arch louvres, and front Triplex dampers synergize with the Active Ride Height system to deliver extraordinary grip and steering accuracy.

Power-to-Weight Superiority: Beyond the One:1

Ten years after the revolutionary One:1, Koenigsegg raises the bar again. Sadair’s Spear drops 35 kg thanks to lightweight carbon-fibre architecture and an uncompromising interior.

Performance figures are staggering, especially with E85 fuel, pushing the hypercar beyond the famed 1:1 power-to-weight ratio—still a Koenigsegg exclusive.

Interior: Precision with Purpose

Inside, Sadair’s Spear is a study in minimalist aggression.

Racing seats, reduced insulation, and carbon fibre components reduce weight while maintaining Koenigsegg’s signature luxuries: SmartCluster, SmartCenter interface, USB connectivity, inductive phone charging, and birds-eye parking assist.

Gear shifts are managed solely through steering wheel paddles in line with its track-focused ethos.

Looking Ahead

With just 30 examples, all of which were privately sold before public unveiling, the Sadair’s Spear cements itself as an instant icon. In its debut shakedown at Gotland Ring, it outpaced the Jesko Attack by 1.1 seconds—a glimpse into the dominion it is destined to hold.

Christian von Koenigsegg aptly concludes:

“Achieving such track dominance in a fully road-legal vehicle is nothing short of remarkable.”

Sadair’s Spear is not just a car—it is a legacy carved in carbon, power, and passion.
