The Koenigsegg Jesko Attack has long stood as one of the world’s most extreme hypercars, but the Swedish performance marque has taken things even further with a new, track-optimized evolution: the Sadair’s Spear. This latest version isn’t just a subtle update — it represents a comprehensive improvement across virtually every aspect of the car, including power, aerodynamics, weight, chassis tuning, and even interior components. Despite its sharpened track focus, the Sadair’s Spear remains fully street legal worldwide, offering an exhilarating driving experience both on the circuit and on public roads.
Production of the Sadair’s Spear is capped at just 30 units, and unsurprisingly, every single one has already been sold, though Koenigsegg has not disclosed the official price. Company founder Christian von Koenigsegg described the model as being “destined to set records,” and the car has already proven its potential by lapping Sweden’s Gotland Ring a full 1.1 seconds faster than the Jesko Attack — no small feat in the hypercar world.
Under the hood, Koenigsegg’s signature twin-turbocharged V8 returns with more performance than ever. Thanks to recalibrated engine software and improved cooling systems, output rises to 1,300 horsepower on regular unleaded fuel and a staggering 1,625 horsepower when using E85 biofuel. These figures represent modest but meaningful gains of 20 hp and 25 hp over the Jesko Attack. Power is sent exclusively to the rear wheels via the brand’s revolutionary Light Speed Transmission (LST) — a flywheel-free gearbox that operates entirely through steering wheel-mounted paddle shifters.
Weight reduction plays a critical role in the Sadair’s Spear performance. Engineers have shaved 35 kilograms off the Jesko’s already featherweight frame, helping the car exceed the coveted 1:1 power-to-weight ratio, a benchmark first introduced with the Koenigsegg One:1. To enhance handling, the chassis has been retuned with lighter suspension springs and Triplex dampers developed in-house. Upgraded carbon-ceramic brakes with new, more robust materials provide consistent stopping power under extreme conditions.
Aerodynamics have also received significant attention. A newly designed double-blade active rear wing boosts downforce, working in tandem with optimized underbody strakes, redesigned canards, side intakes, hood vents, and wheel arch louvres. The rear end has been extended slightly to improve stability, and the car rides on bespoke Aircore carbon fiber wheels with a directional turbine-style design at each corner, wrapped in wider track-spec tires to improve grip.
Inside the cabin, weight savings continue with carbon fiber racing seats, a revised center console, and minimal sound insulation. Even lightweight components have been used throughout to keep mass as low as possible. Though racing-focused, the car doesn’t forget comfort and convenience — features like wireless charging, a digital SmartCluster instrument display, and birds-eye parking assist are still included. Standard safety gear includes three-point seatbelts, while a six-point racing harness is available for more hardcore users.
Altogether, the Sadair’s Spear is a bold statement from Koenigsegg — a hypercar designed to dominate the track, dazzle on the streets, and set a new benchmark in performance engineering.
