Koenigsegg Breaks Production Car Record at Laguna Seca

New record…again!

Just a few months after setting a new production car record at Laguna Seca with its Jesko Attack model, Koenigsegg returned with its Sadair’s Spear and established a new lap record for homologated production cars at WeatherTech Raceway Laguna Seca on November 4, 2025. Despite a strict 90 dB noise limit on the day — a challenge met by fitting an additional, heavy muffler behind the rear of the Sadair’s Spear — factory test driver Markus Lundh achieved a blistering lap time of 1:24.16, verified by Racelogic. With minimal time on track, this achievement highlights the outstanding performance of the Sadair’s Spear and Koenigsegg’s proven in-house engineering solutions — even while contending with the added pendulum weight of the auxiliary muffler mounted behind the car.

Highlights

A new lightweight, top-mounted double-blade active rear wing optimized for increased downforce.
Elongated rear-end design to enhance aerodynamic efficiency and stability.
Expanded front canards, louvres, and reengineered hood vents, including a new Gurney flap, delivering superior cooling for sustained high-performance.
Redesigned air intakes for enhanced engine breathing, adding 20hp with standard fuel and 25hp using E85.
Improved oil cooling capability, essential for sustained track driving in high-temperature conditions.
Exclusive Sadair’s Spear 7-spoke turbine-blade Aircore carbon fibre wheels, with unique directional designs at each corner.
Upgraded wider, track-oriented tires for exceptional grip.
Bespoke suspension setup featuring lightweight springs and Koenigsegg-designed Triplex dampers for superior track handling.
Enhanced multi-layer carbon-ceramic brakes with upgraded pad materials.
Bespoke interior styling exclusive to Sadair’s Spear.
Unique Sadair’s Spear racing seats with optional 6-point harnesses.

Christian von Koenigsegg, Founder and President

“We knew that the Sadair’s Spear had the potential to beat the lap record. To achieve this feat with the added muffler behind the car shows the potential for even greater performance on a less noise-restricted day. That the everyday-usable and livable Sadair’s Spear — with Autoskin, electric seats, sound deadening, amplifiers, and more — can outperform stripped-out track cars is a true testament to the depth of engineering that goes into our creations. I am very proud of our results and achievements, made possible only through solid and passionate teamwork.”
