A £4 million hypercar in 4,000 pieces – I tried the LEGO Technic Koenigsegg Sadair’s Spear

The Koenigsegg Sadair’s Spear is the latest model in Lego’s Ultimate Car Concept range, and inducts the Swedish megacar into an even more exclusive collection of just six cars. The Lego Technic model provides not just a visually accurate interpretation of the car, but it mimics some of the Spear’s most notable features.

Koenigsegg is a Swedish success story, rising from the boyhood dream of Christian von Koenigsegg to one of the most sought-after luxury supercar producers in the world. From its pristine factory in southern Sweden, it produces just 70 cars a year and has a waiting list of over seven years for new models.

The Sadair’s Spear joined the line-up in 2025, named after the horse his father, Jesko, rode in his last race in 1976. Costing roughly £4 million each, only 30 cars exist, and every one was sold before they were even made. They are now changing hands between collectors for even more.

This is the kind of car that kids (and adults) put pictures of on their wall. It’s a road-legal track-inspired megacar, with a 5.0-litre V8, 1603hp, a huge spoiler and Koenigsegg’s signature fighter jet-style windscreen. Megacar is a term reserved for those supercars with a power-to-weight ratio of greater than 1:1, and the Sadiar’s Spear produces 1,157 horsepower per tonne.

It also boasts the impressive Lightning Speed Transmission (LST) for instant shifts through its nine gears, a unique triplex suspension system and the signature Koenigsegg Ghost mode, which raises the huge rear wing, the bonnet, and opens both dihedral doors.

A technical challenge

Creating a Lego Technic version of the Sadair’s Spear was a challenge that took its designers over a year and a half – longer than any previous Ultimate Car Concept. The 4,104-piece model is 59cm long, 28cm wide and weighs nearly 3kg.

The really clever part is that the Lego Sadair’s Spear features working versions of the suspension and the sequential 9-speed gearbox; the paddles on the steering wheel click forward and back, switching the gears through the series of cogs visible at the back of the car at a slightly larger-than-life scale.

“It doesn’t matter how many times I try to explain the light speed transmission,” says CEO Christian von Koenigsegg, “but here we don’t need to. Here you can build it and see for yourself how it works.”

The model also replicates the Ghost mode. Lift the rear section of the car and the bonnet and doors automatically follow, thanks to some mind-boggling engineering. This movement has become synonymous with Koenigsegg, and is a nod to the Swedish Air Force’s Ghost Squadron, from which the ghost logo comes.

Hands-on

The clever part about Lego models, including the Technic range, is that they all rely on standardised pieces. Of the 4,104 in this set, only 90 pieces had been specially made for the Koenigsegg, including the wishbone suspension, the cogs to allow the nine-gear movement and the roof panels.

Two things really struck me about the Lego Technic Sadair’s Spear. The first was how close the design looks to the real car. The attention to detail, down to the way the doors open and the seven-spoke turbine blade Aircore carbon-fibre alloys, is really impressive. The second is just how big this model is. Built at a 1:8 scale, the size and weight are significant, and you will need plenty of shelf space to display it properly once you’ve finished – and you’ll want to show this off.

The way the sequential gearbox has been designed for this model is really stunning. Not only can you change through the gears using the paddles, but the different gears then offer different levels of torque to the wheels, due to the pistons moving at different speeds in the car’s engine. The way the Triplex wishbone suspension operates is also highly accurate, providing real shock absorbers in the model.

Like most who saw the Sadiar’s Spear, though, I had to try out the Ghost mode. In the real car, this is activated from the key, but on the model you manually raise the rear section. As it raises, the doors open, folding upwards and the wing mirrors fold in, as they do on the real car. The bonnet also raises at the same time, all connected by a series of pieces under the gearbox. You can also open the doors individually by pressing a small button further back in the car’s body.

There is one difference though from the real car – aside from the price – and that’s the colour. The Sadiar’s Spear is finished in a dark brown metallic paint; for the model though, Lego has chosen black. During prototyping, versions of the brown were tried, but it was decided the colour didn’t look as appealing in Technic Lego, and adding the metallic effect was not feasible. The use of orange for the interior and details gives the model a sporty feel that matches the original car.

Building it

Kasper René Hansen, Lego’s lead designer on the project, told me that the original building meetings, where he briefed the team on how to build the Sadair’s Spear, took a full week. Once the instruction manual was finished, that build time reduced to three solid days.

For us non-professional builders, I expect you will need significantly longer. Not that you’d want to rush this process – it is, after all, what makes Lego so fun. This is the biggest of the Ultimate Car Concepts to date, beating the McLaren P1 by around 200 pieces; it’s also only the second model to have a removable roof, matching the real car and allowing you to get a better view inside.

Full-size cars

Not content with making one of the most impressive scale models of the Sadiar’s Spear, Lego also set its large format specialists to work and created a life-sized Lego version. Following projects like the Lego F1 cars last year, this 1:1 version looks just like the real car, and it drives – fast.

The full-sized model is made from 327,906 pieces and took more than 9,400 hours to develop and construct. Fitted with dual motors and a large electric battery, it’s considerably faster than previous full-scale Lego models. The team’s aim was to allow the car to reach 100km/h (62mph).

Testing the full-size model at Goodwood on a reverse route of the hill climb, the Lego Sadiar’s Spear reached 111km/h (69mph) with Koenigsegg Test Driver, Markus Lundh, behind the wheel. The model is expected to debut at Aurora, the Scandinavian Concours and be back at Goodwood for the Festival of Speed later this month.

The Lego Technic Koenigsegg Sadair’s Spear is available to buy on the Lego store from 4 July 2026 (with early access for Lego Insiders from 1 July) priced £399.99 / €449.99 / $449.99. Those who buy the model before 6 July will also receive a LEGO Technic Koenigsegg Sadair’s Spear Steering Wheel model set as a special gift.
