Parts review: 42232 Koenigsegg Sadair's Spear Megacar™ from LEGO® Technic

A lot has been said about the apparent overload of cars flooding the LEGO® Technic theme in recent years, and I have to agree with the critics. There is one clear exception for me though: the Ultimate Car Concept Series are a staple of the theme. This is where the LEGO® Technic System aspect has the space and budget to really shine, and I am always impatiently surviving the 2 years between each edition. This year, Swedish car manufacturer Koenigsegg has the honor of providing a model for us to build and in my first article examining set 42232 Koenigsegg Sadair's Spear Megacar™, I will explore all of its new elements.

As I’ve stated before, I am not really a car person: to me they often look alike, and I am not really interested in 0-100 stats, torque or top speeds. But I do love LEGO Technic, and with that, complex drivetrains, gearboxes and mechanical functions. In that regard, the Ultimate Car Concept Series is the perfect subtheme. Where cars in the Car Transporter Scale often fall short due to their size and the limited functions that can fit inside, these massive beasts can pack in everything I need. 

The 42232 Koenigsegg Sadair's Spear Megacar is the 6th in the series, and with 4104 parts, the biggest so far. I’ve built the last 3 editions, and enjoyed every one. That does set a high bar for the Swedish entry, and I am eager to start building.

But, since this is New Elementary, I’ll first go through all the bags and dig out all the new elements for a closer look, and save the build for a follow up blog article. 

As usual, the new elements are split up into new molds, recolors and decorated elements. Since there are a whopping 14 new molds to discuss, I’ve split up this section in 3 categories: gears, suspension and panels.

New molds: Gears

Gear Shifter with Groove, 40° Axle Offset (7445) & Gear Shifter with Groove, 60° Axle Offset (7446)

Although I had a blast building the super cars, I was a bit let down by 42143 Ferrari Daytona SP3 as its gearbox – my favorite part of all of these cars – was nearly identical to its predecessor 42115 Lamborghini Sián FKP 37.

In 2023, a new type of gear shifter was introduced, revolutionising the way gear boxes are set up. Zach reviewed the first set the part appears in, 42159 Yamaha MT‑10 SP, and explored the new gear shifter functionality. 

In short: the shifter consists of a drum (part 4158, shown in medium azure) with a curved groove in it. This allows the Gear Shifter Fork (4159, orange) to fit in it, and move up and down along the curves, in turn moving Technic Driving Ring 2L (2473, dark bluish grey), which then clutches onto a gear. 

This system was also used in the previous Ultimate Car Concept, 42172 McLaren P1 from 2024, dismissing my fears after the letdown of the Ferrari. Alex reviewed the LEGO Technic P1 in detail.

The Koeningsegg uses a similar system, but the 9-speed gearbox has given it a new twist – literally – by introducing 2 new gear shifters:

• 3x Gear Shifter with Groove, 40° Axle Offset in Red (6546505 | 7445)
• 3x Gear Shifter with Groove, 60° Axle Offset in Yellow (6546506 | 7446)

Where the original shifter has 8 steps to cycle through, these 2 new molds have 9 steps, matching the 9-speed gearbox. As you can see in the image above, the yellow version has ‘A’, ‘B’ and ‘C’ marked on the side, at 120° intervals or 3 steps spread apart. The red version has 1, 2 and 3 marked on successive steps. 

Another thing to spot is the groove: where the original version goes both up and down, resulting in aa A/Off/B switch, these versions only go up or down (depending on how you flip them around), resulting in an On/Off switch. The red version follows the pattern Off-Off-On-Off-Off-On-Off-Off-On, while the yellow goes Off-Off-Off-Off-Off-Off-On-On-On.

Harder to spot is a difference in the axle connectors. The original version (seen in medium azure above) has both axle holes sitting at a 45° offset, which means lining up 8 of them will result in a full rotation. The yellow version has the holes sitting under a 30° offset, requiring 12 drums to line up for a full rotation. Meanwhile, the red version has a 60° offset, requiring 6 drums to end up at the start again. I assume this change is also related to the 9-speed gearbox; I can’t wait to start building it to find out how it all works. With 3 of each being used, I am also a bit intimidated though.

Technic Gear Stepper 9 Tooth (116065)

In order to let the new gear shifters rotate in 9 steps, a new stepper gear is introduced:

• 3x Technic Gear Stepper 9 Tooth in White (6591335 | 116065)

The part is similar to the version used for the original gear shifter, Technic Gear Stepper 8 Tooth (2474, seen in yellow above). The teeth have been made smaller, while keeping a similar diameter, and this time the part uses 2 colors of plastic. Since the alignment on an axle with 9 teeth is more important than with a neat double-symmetrical 8 teeth, the tooth aligning with the axle hole has easy identification by using the white from the center section.

I could spend a lot of words describing the new gear shifters, but a video might make it clearer:

Technic Gear 14 Tooth (7785)

The gearbox also requires some new gears, starting with the return of a classic.

• 1x Technic Gear 14 Tooth in White (6569662 | 7785)

The last time we had a 14-tooth gear was back in 2002 with Technic Gear 14 Tooth Bevel (4143), and now we get a regular version. There is also the Samsonite version (741) from the 1960s and Technic Gear 14 Tooth Bevel (69762) from the new differential system, but these both fall under a different standard.

Technic Gear 18 Tooth with Clutch on Both Sides (7786)

Another new gear has 18 teeth, but also a clutch.

• 1x Technic Gear 18 Tooth with Clutch on Both Sides in Orange (6569664 | 7786)

With 18 being divisible by 9, I suspect this gear was required for the 9-speed gearbox, but we’ll find out once I start building. 

Matching up these two new gears with the existing gears might prove tricky, but at least they do mesh together perfectly. The 18-tooth gear also meshes with the old bevel version, but that gear is so flat it requires a spacer.

New teeth counts are always welcome, expanding the family. Going counter-clockwise from the bottom, we have the 24, 20, 18, 16, 14, 12 and 8-tooth versions. I left out the 28, 36, 40 and the new 64-tooth versions here.

Technic Gear 8 Tooth with Clutch on One Side (7557)

But we’re not done yet! There is another new gear with an existing tooth count that receives a clutch:

• 2x Technic Gear 8 Tooth with Clutch on One Side in Red (6556509 | 7557)

Like its 16-tooth sibling, the 8-tooth version required an extension to fit in the large clutch. 

Going counter-clockwise from the bottom, this family now includes 8, 16, 18, 20 and 24-tooth versions.

New molds: Suspension

The car uses a new suspension with some all-new molds, as well as some updates.

Technic Wishbone 7 x 7 x 4 (7558)

One of the all-new molds is the wishbone.

• 4x Technic Wishbone 7 x 7 x 4 in Light Bluish Gray (6556510 | 7558)

I can imagine many people using this piece in LEGO® System or CCBS creations purely for its aesthetic appeal.

Judging by this image from the instructions, the wishbones seem to have specifically been made for this car.

Technic Steering Wheel Hub Holder with 2 Ball Joints and 2 Axle Holes (7169) & Brake Disc with CV Ball Joint (7168)

The wheels are mounted on a new brake disc, which in turn sit on a new hub holder.

• 4x Brake Disc with CV Ball Joint in Dark Bluish Gray (6613815 | 7168)

• 4x Technic Steering Wheel Hub Holder with 2 Ball Joints and 2 Axle Holes in Black (6583540 | 7169)

Both molds are updates to the current Technic Steering Wheel Hub Holder with 2 Pin Holes and 2 Axle Holes (65766) and Brake Disc (35189), with some functional differences.

The original wheel holder (above right) featured pin holes at the top and bottom, which are replaced by ball joints on the new version (left). The central hole is also different.

That updated hole is because of changes in the brake disc. The original disc (right) has a small CV Joint connection. The new version (left) has a CV Ball Joint, which requires a larger hole. What does stay the same is that once joined, the holder and disc are nearly impossible to separate without damaging the parts.

Technic Shock Absorber 13L & Technic Shock Absorber 6L

Providing a smooth ride are 2 new shock absorbers to form the special Triplex Suspension.

• 2x Technic Shock Absorber 13L with Black Spring in Light Bluish Gray (6579396)
• 4x Technic Shock Absorber 6L with Black Spring in Light Bluish Gray (6579418)

At this moment, a Design ID is not yet known. The 3 plastic parts on the short version are marked 7157, 7158 and 7159. On the larger version, I can only read the black spring, showing 7167.

The new absorbers are seemingly siblings of Technic Shock Absorber 9L (79717) introduced in 2022, seen above center. As with this version, the black spring is merely decorative: the real work is done by a metal coil inside the absorber. The 13L has a travel of just over 2 modules resulting in a length just under 11L, while the short version can be suppressed to just under 5L.

Wheel 75 x 41 Koenigsegg Left & Right (7444 / 7783)

Of course, all those parts are there for one reason: the wheels. 

• 2x Wheel 75 x 41 Koenigsegg Right in Pearl Titanium (6546504 | 7444)
• 2x Wheel 75 x 41 Koenigsegg Left in Pearl Titanium (6569660 | 7783)

They come in a left and right side, and fit Tyre 87.9 x 44 Low (80279), which were also used in the previous 2 super cars: 42143 Ferrari Daytona SP3 and 42172 McLaren P1.

New molds: Panels

Technic Panel Round Corner 5 x 5 x 2 (7661)

Usually, these large cars introduce some large panels, and there's nothing wrong with that when necessary, but I always prefer when designers achieve the right shape of the car by utilizing existing molds. I am glad to see only a smaller, more useful new panel is introduced here.

• 2x Technic Panel Round Corner 5 x 5 x 2 in Black (6563324 | 7661)

The curve lines up with other 5L panels, like Technic Panel Round Corner 5 x 3 x 2 (2442, 2438) seen here in trans-clear, and Technic Beam 2 x 5 L-Shape with Quarter Ellipse Thick (80286) in light bluish grey.

Recolors

After that onslaught of new molds, the 20 recolors feel less impressive. Still, we get some useful new elements here.

The bonnet and spoiler of the car utilize many new Dark Tan elements:

• 6x Technic Beam 1 x 13 Thick in Dark Tan (6593766 | 41239)
• 7x Technic Beam 1 x 7 Thick in Dark Tan (6598853 | 32524)

• 2x Technic Beam 2 x 5 L-Shape with Quarter Ellipse Thick in Dark Tan (6593767 | 80286)
• 2x Technic Beam 2 x 3 L-Shape with Quarter Ellipse Thick in Dark Tan (6593763 | 71708)
• 4x Technic Axle Connector Smooth in Dark Tan (6593775 | 59443)
• 2x Technic Panel 3 x 2 x 5 in Dark Tan (6593777 | 80285)
• 2x Technic Beam 2 x 4 L-Shape Thick in Dark Tan (6593761 | 32140, 42137)

• 10x Technic Panel Fairing 2 x 3 x 1 in Dark Tan (6593772 | 71682)
• 3x Technic Panel Fairing #7 3L Very Small Smooth, Side A in Dark Tan (6593778 | 2387)
• 2x Technic Panel Fairing #9 Medium Triangle Smooth in Dark Tan (6593768 | 2395)
• 2x Technic Panel Fairing #10 Medium Triangle Smooth in Dark Tan (6593762 | 2403)
• 3x Technic Panel Fairing #8 3L Very Small Smooth, Side B in Dark Tan (6593769 | 2389)
• 1x Technic Panel Fairing 2 x 1 x 1 in Dark Tan (6593773 | 89679)
• 1x Technic Rotor Blade Small with Hole and Axle Connector End in Dark Tan (6593779 | 99012, 58489)

• 1x Technic Panel Curved 5 x 13 x 3 Tapered, Left #54 in Black (6593764 | 4443)
• 1x Technic Panel Curved 5 x 13 x 3 Tapered, Right #55 in Black (6593759 | 4446)
• 2x Technic Panel Car Mudguard Arched 15 x 2 x 6, Arched Top in Black (6593760 | 4427)
• 2x Technic Panel Car Mudguard Arched 13 x 2 x 5, Arched Top, Pointed Bottom in Black (6593758 | 80284)

• 1x Technic Panel Curved 7 x 3 with 2 Pin Holes through Panel Surface in Reddish Orange (6593765 | 24119)
• 1x Technic Steering / CV Ball Joint Female 4L in Orange (6563322 | 52730)

Decorated elements

Let's start with the most important bit: there are no stickers! Instead, we get 21 newly decorated elements.

• 3x Technic Panel Fairing 2 x 5 x 1 with print in Dark Tan (6592921)

• 2x Technic Panel Fairing #7 3L Very Small Smooth, Side A with print in Black (6592923)
• 2x Technic Panel Fairing #8 3L Very Small Smooth, Side B with print in Black (6592922)

• 4x Technic Panel Fairing 2 x 3 x 1 with print in Black (6592914)

• 3x Technic Panel Fairing 2 x 3 x 1 with print in Black (6592913)
• 1x Technic Panel Fairing 2 x 3 x 1 with print in Black (6592912)
• 1x Technic Panel Fairing 2 x 3 x 1 with print in Black (6592919)

• 1x Technic Beam 2 x 3 L-Shape with Quarter Ellipse Thick with print in Black (6592917)

• 1x Technic Panel Curved 3 x 13 x 2 Tapered, Left with print in Black (6592909)
• 1x Technic Panel Curved 5 x 13 x 3 Tapered, Left #54 with print in Black (6592920)
• 1x Technic Panel Curved 5 x 13 x 3 Tapered, Right #55 with print in Black (6592925)
• 1x Technic Panel Curved 3 x 13 x 2 Tapered, Right with print in Black (6592908)

I’m not sure if I am happy with having printed headlights, as I prefer the brick-built solutions from other cars.

• 1x Technic Disc 3 x 3 with print in Black (6592918)

One thing that always annoyed me in the previous super cars was not knowing in which gear the car was driving. In this car, we get a nice indicator.

• 4x Tile Round 2 x 2 with print in Black (6592927)

• 2x Tile 2 x 3 with print in Black (6592910)
• 1x Tile 2 x 4 with Groove with print in Black (6592915)

• 1x Tile 8 x 16 with Bottom Tubes with print in Black (6592916)

• 4x + spare Tile Round 1 x 1 with print in Light Bluish Gray (6592926)

• 2x Tile 2 x 3 with print in Reddish Orange (6592911)
• 4x Slope Curved 4 x 1 Double with No Studs with print in Reddish Orange (6592924)

• Tile 1 x 4 with Groove with print in White (6615639)

As with the previous cars, each set comes with a unique code to unlock goodies.

Conclusion

As is fitting for a Ultimate Car Concept, the 42232 Koenigsegg Sadair's Spear Megacar introduces a stunning quantity of new elements, and with that, potentially many new options for car designers. 

To assess that potential, we’ll need to start building the car, and I have to be honest: I am a little scared to try and figure out how this gear box is going to work. Schematics like these, found in the building instructions, are pretty intimidating, but I’ll do my best!
