Thought the 1,578hp, bewinged Jesko Attack was as extreme as road-legal Koenigseggs could get? Christian von Koenigsegg begs to differ, because here is the new Koenigsegg Sadair’s Spear, a lighter, more powerful, more downforce-y, and therefore more track-focused take on the brand’s hypercar, designed to wreak havoc on your concept of fast and rearrange your internal organs.
First, that name. You may recall that Jesko was named after Christian’s father for his 80th birthday, to say thanks for his help with the company in its early years. Beats a pair of socks. You probably didn’t know that Jesko von Koenigsegg was a keen jockey, nor the name of the horse he rode in his final race in 1976. Yep, Sadair’s Spear.


The engine is familiar from the Jesko, a 5.0-liter twin-turbo V8 connected to the carmaker’s nine-speed Lightspeed transmission. It does without a flywheel, so it revs to its 8,500rpm redline like a superbike in 0.2sec. Here, revised engine calibration, redesigned air intakes, and improved cooling mean peak power climbs by 25hp to 1,603hp on E85 (1,282hp on regular unleaded).

No word on acceleration or top-speed figures (the Jesko has a theoretical top speed north of 480kph), only that during its shakedown, it smashed the Gotland Ring lap record by 1.1sec. Previous record holder? The Jesko Attack.
Improved aero has a big part to play in that. The active top-mounted ‘double-blade’ rear wing combines with a stretched rear-end design for more downforce and stability. That’s balanced with larger canards, louvres, and hood vents at the front. New seven-spoke turbine-blade Aircore carbon-fiber wheels are specific to the Sadair’s Spear and wrapped in even wider track-focused tires.

The carbon-ceramic brakes get upgraded pad materials, while the self-leveling suspension features lighter springs—part of a total 35kg weight-saving package that includes losing 2.6kg of sound deadening, unique carbon-fiber seats, and other lightweight interior components.
If you love faffing around before going anywhere, you can opt for six-point harnesses instead of normal seatbelts, but this isn’t a fully stripped-out race car—you still get a wheel-mounted digital instrument cluster, a stereo, and wireless charging for your phone.

“Sadair’s Spear represents a natural progression for Koenigsegg—an impeccable balance of raw power, refined aerodynamics, and extraordinary road presence,” said Christian von Koenigsegg. “This car is destined to set records. Achieving such track dominance in a fully road-legal vehicle is nothing short of remarkable.”
The Sadair’s Spear is limited to just 30 cars, each costing £3.8 million (P296 million before taxes). The full allocation sold out instantly when Koenigsegg gave its most loyal customers a private viewing. Better luck next time.
