Sadair’s Spear may be a dressed-up Jesko, but the details make all the difference

The newest Koenigsegg model, dubbed Sadair’s Spear, is actually heavily based on an existing model: the Jesko. Specifically, the Jesko Attack, the most all-out version of the car. Looking at the two side by side, the differences might not immediately jump out and grab you, but rest assured, there are plenty of subtle and not-so-subtle tweaks. In pursuit of quicker lap times and an even more uncompromising representation of performance, Christian von Koenigsegg has turned the former leader of Ghost Squadron into an even more impressive machine. Here’s everything the mad Swede did to build the Jesko’s logical — and peerless — evolution.

Dress for the occasion; the Sadair’s Spear dons more appropriate exterior details

In the front, the Sadair’s Spear expands on the Jesko’s carbon aero bits but stays close to the original design. The front flicks are more prominent, and the wheel arch louvres are redesigned, looking just a little bit more aggressive. Behind the driver, there are small tweaks to the Jesko’s trademark double-blade rear wing, a high-mounted third brake light, and a new undertray design. The rear bumper is also different, now better showcasing the car’s cooling system. According to Koenigsegg, the Sadair’s Spear offers improved oil cooling capabilities for longer stints on the track in high-temp conditions, and the carbon fiber diffuser now wraps all the way around the rear bumper. Across the side, near the rear air intakes, spear-shaped elements commemorate the car’s namesake. Finally, those seven-spoke carbon fiber wheels are unique to the Sadair’s Spear.

An interior befitting a $5 million price tag

While the changes on the outside are important, but maybe not immediately obvious, the interior keeps things even more subtle. Most obvious are the racing seats with optional six-point harnesses and removal of the gear lever. That latter change means using paddle shifters is the only way to pilot the Spear. Past that, we kind of have to take Koenigsegg’s word for it. They say Sadair’s Spear features a “bespoke interior styling” that is completely unique to the car.

You won’t have to look as hard to find performance improvements, though. Koenigsegg modified the car’s air intakes to gain 20 horsepower or 25 horsepower, depending on the fuel used. The biggest gains are only possible with E85. The automaker fitted wider tires and retuned the suspension for even better on-track handling. In fact, at least in photos, the Sadair’s Spear seems to sit noticeably lower to the ground than the Jesko. Finally, they’ve given the car's carbon ceramic brakes better pads for quicker and later braking.

Final thoughts

We weren’t on the short list for the Sadair’s Spear, and since all 30 of them are already sold, we’re guessing buyers were impressed enough with the changes to open their wallets. But apart from the very noticeable differences in the rear bumper, it really would take an eagle eye to distinguish the Sadair’s Spear from the Jesko. With up to 1,625 horsepower on tap when using E85 fuel and a 35 kg (77 pounds) cut from the Jesko, it’s clear the Sadair’s Spear will be the better performer in almost any metric.
