Koenigsegg Sadair’s Spear
Only Christian von Koenigsegg—the entrepreneur and founder of the company that bears his name—could look at the Jesko, his latest 1,600-horsepower hypercar, and conclude that it needed more power. Thus, the Sadair’s Spear was born, making its debut in the summer of 2025.
At its heart lies a twin-turbocharged 5.0-liter V8 engine producing 1,300 hp and 1,000 Nm (102 kgm) when running on premium 98-octane gasoline. However, fill the tank with E85 ethanol fuel—widely used in several countries as a lower-emission alternative—and update the engine management system for flex-fuel operation, and boost pressure rises from 1.7 to 2.2 bar. The result is an astonishing 1,625 hp and 1,500 Nm (152.9 kgm) of torque.
The additional 20–25 horsepower (depending on the fuel used) comes courtesy of a new engine management system, a redesigned air-intake setup, and an upgraded cooling system. These are complemented by further enhancements, including a revised aerodynamic package designed to generate even greater downforce.
Surprisingly, Koenigsegg has not published the car’s acceleration figures, instead focusing on its top speed of 350 km/h (217 mph). There is a reason for that: this is not a car built to break top-speed records, but rather to dominate lap times—and that leads directly to the story behind its name.
Founded in 1994 by Christian von Koenigsegg, the Swedish marque has produced some of the world’s fastest cars and set numerous performance records. It even flirted with the idea of acquiring fellow Swedish automaker Saab from General Motors. Yet perhaps nothing is more impressive than this act of honoring a father.
The Jesko is named after Christian’s father, Jesko von Koenigsegg, and was designed with extreme speed in mind, even setting the record for the fastest 0–400 km/h–0 run at 25.2 seconds. The Sadair’s Spear, meanwhile, takes its name from the last horse Jesko rode during his career as a gentleman jockey. That racing heritage explains the car’s singular focus on lap times and track performance.
Bottom Line: Koenigsegg’s second attempt to take an already outrageous hypercar to an even higher level.
Price: Approximately $5 million.
