42232 Koenigsegg Sadair's Spear Megacar is the sixth in the series of Technic Ultimate Cars that began in 2016 with 42056 Porsche 911 GT3 RS.
Each one has improved on its predecessors, and this is the most sophisticated yet. The car's 9-speed transmission and Triplex suspension have been replicated faithfully, as has the vehicle's intriguingly-named 'ghost-mode' party trick.
The prototype
Koenigsegg Sadair's Spear, named after the racehorse the Swedish company's founder's father used to ride, is a road-legal supercar that'll set you back a cool £3.8 million. Just 25 were made, and all have been sold already, so you'll have to make do with the 1:8 scale LEGO version costing a fraction of that.
The completed model
Up until now, Technic Ultimate Cars have replicated the livery of a real-life example, but the introduction in the instructions explains that in this case LEGO experimented with colours that have been used on Koenigsegg cars before to come up with a new unique livery, one that differentiated it from other models in the collection.
The result is a predominately black vehicle with dark tan highlights and a reddish-orange interior. Black would not have been my first choice given its ubiquity, but it doesn't look too bad. Presumably, the budget did not stretch to creating a new colour and all the parts needed to replicate the livery of the one above and, let's face it, a brown car would look awful anyway.
At 1:8 scale it's pretty much the same size as others in the series, 59cm long by 24cm wide, excluding the wing mirrors. All decorated parts in the set are printed, which includes logos, branding and orange stripes.
In terms of functionality, the model has the aforementioned 9-speed gearbox, front- and rear-suspension, and steering via the steering wheel, plus opening doors, bonnet, and rear clamshell (what we in the UK might call the boot.)
The real car does not have a removable roof, but the model does, which is handy for admiring the interior and operating the gearbox.
Unlike some in the Technic Ultimate Car series, the gearbox is visible from underneath.
The real car has a party trick called ghost-mode, named after the manufacturer's association with the Swedish Air Force's Ghost Squadron emblem (its factory occupies a former air force base). Its primary purpose is theatrical, demonstrating the car's unique bodywork and Koenigsegg's engineering.
It's activated by lifting the rear clamshell (boot). As it is raised, thanks to clever linkage inside the chassis, the dihedral synchro-helix doors open, the wing mirrors fold in, and the bonnet opens.
Unfortunately, they have to be lowered and closed separately manually.
Despite being predominately black, it actually looks quite colourful from some angles, thanks to the bright interior and stripes on the bodywork.
As always, the curves of the bodywork are approximated using existing Technic panels and shells, and generally the designer has done a good job, although there are a few unsightly gaps in places, particularly noticeable above the backs of the front wheel arches. The titanium metallic wheel hubs are new, and differ between left and right.
The headlights and front air intakes are printed on panels.
In contrast, the rear lights are brick-built and look very good.
I don't know what you'd see if you lifted the bonnet on the real car but here you can see that the front suspension occupies most of the space. There's a picture of the front axle assembly in the construction section below that shows the Triplex suspension arrangement better.
Lifting the rear clamshell reveals the 5-litre V8 engine and rear suspension.
The gearbox is operated using two paddles on either side of the steering wheel, and a sliding R/N/D control between the seats. Pulling one towards you shifts up, pulling the other shifts down. It does not stop when you get to 1 and 9, so you can go straight from 1st to 9th if you're not careful!
Unlike previous Technic Ultimate Cars it's possible to see which gear is selected thanks to a disc behind the driver's seat. But, in common with them, the difference between gears is imperceptible, manifesting itself as a miniscule difference in the speed the cylinders in the engine raise and lower as you push it along the floor. However, as always, it's nice to know that the model incorporates the gearbox, and we'd probably complain if it didn't...
As I said before, all decorated parts are printed, including panels with the car's name and a ghost symbol. It seems that, despite the car's name having an apostrophe in Sadair's, it is not present on the car's logos.
The vehicle is accompanied by a display plaque that shows pertinent details about it which matches those of the previous three Technic Ultimate Cars.
Packaging and instructions
Previous Technic Ultimate Cars have come in premium packaging and this one is no different, although it's not quite as premium as some. The front of the box shows a side view of the model in the white section with an equivalent view of the real vehicle below it. What would normally be shown on the front of the box is on the back.
Inside, parts bags are distributed between three shallower boxes, which prevents you being overwhelmed by all 30 of them at once. The bottom of the box has indents to hold the two instruction manuals in place.
Each book comprises about 500 pages and overall there are 1,171 instruction steps.
As has become customary for this type of set, the first manual contains a wealth of information about Koenigsegg, the real car, the design process, and so on. If you're interested in all that but don't intend to buy the set, you can download the instructions from LEGO.com
Construction
As you might expect with a model of this size and complexity, it takes a long time to build, and requires concentration throughout the process. I estimate I must have spent around 12 to 15 hours over the course of a week. I did not rush it because I knew I would not have a review ready for the embargo date (it arrived just a few days before), so I took my time and savoured it.
Construction begins with the gearbox, and you will not be surprised to learn that this is the most demanding part of the build, although it was never overwhelming due to the way it's been designed in short sections and split across several bags, giving you checkpoints during the process.
The 9-speed gearbox is the most complicated yet to feature in a Technic Ultimate Car and a number of new pieces were needed to facilitate it, including, from left to right, a 9-tooth stepper gear, an 18-tooth gear with clutch on both sides and a 14-tooth gear.
There are more that I didn't photograph, so head on over to New Elementary for a complete overview of all the new parts and recolours in the set.
The other noteworthy sub-assembly in the model is the front axle which incorporates the Triplex suspension arrangement. The third 'Triplex' damper links the suspension across the axle for improved stability. Again, new pieces were required to implement it in LEGO form.
Here's how the car comes together:
Verdict
The model lives up to its premise as the ultimate Technic car, incorporating the most complex LEGO gearbox assembly yet, authentic Triplex suspension, doors that open the same way as they do on the real car, and a cleverly implemented 'ghost mode'. In fact, everything you would expect to find in such a model is present and correct.
I was not over-enamoured by the black livery when I first saw pictures, but it definitely looks better in the ABS, thanks to the dark tan accents and bright orange interior. One downside of the black, though, is that Technic builders generally have far too many black parts already, so it's not a particularly good parts pack.
Overall, then, a great model, the best Technic Ultimate Car yet, but I can't help but feel slightly underwhelmed: I think it's because there are so many large Technic cars nowadays, so it does not feel quite as special as the Porsche did when it was released 10 years ago.
Surprisingly, the price of the Technic Ultimate Cars has not risen since 2020, so from that point of view, $449.99, £399.99, €449.99 seems fair. I think we can be sure that, like its predecessors, it'll be reduced by at least 20% at Amazon before too long, making it even better value.
If you're looking for a lengthy and challenging build that yields an impressively-sized, great-looking model packed with authentic features and mechanisms, you need look no further.
