Koenigsegg Sadair’s Spear Is Koenigsegg’s Most Hardcore Hypercar Ever

There’s a new Koenigsegg in town! I love typing that. Just ahead of the Goodwood Festival of Speed in two weeks and to celebrate Jesko von Koenigsegg’s 80th birthday, Swedish mad scientist Christian von Koenigsegg has unveiled something new, the Koenigsegg Sadair’s Spear. That’s a weird name, but it pays tribute to the horse Christian’s father, Jesko von Koenigsegg, rode in his final race in 1976. Because of the link with Jesko himself, the car is obviously based on the standard Koenigsegg Jesko, but it’s more hardcore, with less weight, more power, and with a wing that big, more downforce.

It’s still road legal, but it’s had the wick dialed up to extremes, with less weight, a track-focused interior, upgraded brakes and suspension, and more power. At its heart, Sadair’s Spear has a Koenigsegg-built twin-turbo V8 displacing 5.0 liters and producing 1,625 horsepower when fed E85 (1,300 hp on regular unleaded). That’s 25 hp more than the standard Jesko’s peak output on E85 and 20 hp more on regular fuel. Power is sent to the rear axle via Koenigsegg’s Light Speed Transmission, and with no flywheel adding inertia, it can rev at an astonishing 46,000 rpm/s – that’s not peak redline but a measure of how quickly it can pick up revs when the throttle is prodded.

Weight-saving measures implemented include dropping 77 lbs overall, which sees Sadair’s Spear achieve a better power-to-weight ratio than the iconic Koenigsegg One:1.
