Koenigsegg prototype with Sadair’s Spear aero package spied

It’s been just over a week since the track-focused Koenigsegg Sadair’s Spear made its global debut. The new limited-edition hypercar is a lighter and more powerful version of the standard Jesko. It also features a unique aero package, which is now being put through its paces on a prototype.

A Koenigsegg prototype fitted with aero bits from the Sadair’s Spear was recently spotted near the factory. The test car is based on the Jesko Absolut but features an extended front splitter, dive planes, side skirts, fender louvres and a NACA duct on the nose. The rear wing, though, is the same as the Jesko Attack.

Besides the upgraded aero package, the Sadair’s Spear also weighs 35 kg less than the standard Jesko. It is powered by a twin-turbo V8 engine, which delivers 1625 hp on E85 fuel, up from 1300 hp.

The result of all these modifications is a much quicker car overall. Koenigsegg claims that the Sadair’s Spear laps the Gotland Ring racetrack 1.1 seconds faster than the Jesko Attack.

    There’s a mistake in the article. The power for the Sadair Spear is 1300 on pump and 1625 on E85. That’s up from the Jesko’s 1280 on pump and 1600 on E85

    The Laguna Seca lap record and top gear track time would like a word.
