The Sadair’s Spear is a track-focused limited edition derived from the Jesko, offering even greater performance
The Koenigsegg Jesko Attack is already among the fastest hypercars on the planet, but the Swedish automaker just raised the bar. Introducing the Sadair’s Spear—a limited-production, track-focused evolution of the Jesko, boasting more power, less weight, enhanced aerodynamics, and a reworked chassis for ultimate performance.
Unlike many of its hardcore rivals, the Sadair’s Spear remains fully road-legal across global markets. Only 30 units will be built, and all have already been sold at an undisclosed price. According to Christian von Koenigsegg, the car is “destined to set records,” and it already proved that point by lapping Sweden’s Gotland Ring 1.1 seconds faster than the Jesko Attack.
More Power, Less Weight
Koenigsegg re-tuned its twin-turbo V8 with updated calibration and improved cooling. The result? A boost to 1,300 hp (969 kW) on regular gas and up to 1,625 hp (1,212 kW) on E85—gains of 20 and 25 hp over the Jesko Attack. Power continues to route to the rear wheels via the company’s unique flywheel-free Light Speed Transmission, operated solely through paddle shifters.
Weight reduction was another priority: the Sadair’s Spear is 35 kg (77 lbs) lighter than the Jesko, giving it a better-than-1:1 power-to-weight ratio—surpassing even the legendary One:1. A lighter suspension setup with in-house-developed front Triplex dampers and upgraded multi-layer carbon-ceramic brakes further sharpen its handling.
Aerodynamic Evolution
The aero has been refined with a new dual-blade active rear wing, revised underfloor strakes, and reworked body elements—like longer rear overhangs, reshaped front canards, new hood vents, and improved side intakes. The package delivers more downforce and better cooling efficiency.
The car also rides on directional Aircore carbon fiber wheels—unique at each corner—wrapped in wider, track-optimized tires.
Lightweight Cabin with Everyday Tech
Inside, the Sadair’s Spear focuses on function and weight savings. There’s a redesigned center console, carbon fiber seats, reduced insulation, and lightweight trim pieces. While it comes with standard three-point belts, a six-point racing harness is optional. Still, daily usability isn’t forgotten—it retains features like wireless charging, Koenigsegg’s SmartCluster digital display, and birds-eye view parking assist.
What’s in a Name?
The car’s name pays tribute to Sadair’s Spear, the favorite racehorse of Jesko von Koenigsegg—the father of the brand’s founder and namesake of the original Jesko.
Christian von Koenigsegg sums it up best:
“Sadair’s Spear represents a natural progression for Koenigsegg—an impeccable balance of raw power, refined aerodynamics, and extraordinary road presence. Achieving such track dominance in a fully road-legal vehicle is nothing short of remarkable.”
