I went back through LEGO’s UK product pages while planning the next library additions, and I found figures on one of our earlier posts that were wrong. The Koenigsegg 42232 is not an 800-piece, £79.99 set. It is the 4,104-piece Technic Ultimate car at £399.99. Our early Aston Martin figures were wrong as well.
I would rather correct that plainly than leave two versions of the facts on the site. The old article needs a correction at the top, and these are the figures I am using now.
The five sets I would put on the shortlist
- Koenigsegg Sadair’s Spear 42232: 4,104 pieces, £399.99
- Aston Martin Aramco AMR25 F1 Car 42240: 1,547 pieces, £199.99
- Batmobile Tumbler 42239: 719 pieces, £169.99
- 1966 Ford GT40 MKII 42223: 793 pieces, £64.99
- NASA Artemis Space Launch System Rocket 42221: 632 pieces, £54.99
LEGO’s UK shop currently lists these as available or on back order rather than coming soon. I have not found a later confirmed 2026 Technic launch on the official UK pages, so I am not going to invent one to make the headline more exciting.
Koenigsegg 42232: the flagship commitment
The Koenigsegg is the largest set here by a wide margin. LEGO lists 4,104 pieces, a V8 piston engine, nine-speed transmission, triplex suspension and the Ghost Mode mechanism. Lifting the rear clam operates the doors and front bonnet while folding the mirrors.
That one function is the reason I think it earns attention next to the other 1:8 supercars. It is not another body placed over the familiar eight-speed formula. The nine-speed transmission and linked opening sequence give the build its own mechanical identity.
It is also £399.99 and 59 cm long. That means several sessions, a table you can leave occupied and careful checking before the body closes around the gearbox. At the time of checking, LEGO’s UK page said back orders would ship by 7 September. Availability can move, so use the official Koenigsegg 42232 page for the current position.
Aston Martin 42240: more interesting than another F1 shell
The Aston Martin AMR25 is a 1:8 model with 1,547 pieces. LEGO lists front and rear push-rod suspension, steering, a differential, a two-speed gearbox, a V6 engine, a simulated electric motor and DRS linked to the high gear.
That linkage is what I want to see working. On the earlier 1:8 F1 cars, the mechanical package and the shape could feel like separate parts of the model. Here the gearbox setting changes the rear wing. It gives the drivetrain a visible result.
The model is 61 cm long and costs £199.99. The official Aston Martin 42240 page lists it as available now.
Batmobile 42239: the price is in the electronics
The Tumbler has 719 pieces and costs £169.99. Read those two numbers alone and it looks expensive. The set includes a rechargeable battery, app control, steering, lights and a speed-boost function. LEGO says the USB-C cable is not included.
This is a driven model rather than a long static build. I would judge it on how well it drives, how easy the battery is to charge and whether the CONTROL+ experience stays useful once the first few runs are over. The subject will bring people to it, but app support and battery condition are the workshop questions that matter in a rental library.
The current details are on the official Batmobile Tumbler 42239 page.
Ford GT40 42223: probably the easiest yes
The 1966 Ford GT40 MKII is 793 pieces, £64.99 and 29 cm long. It has top-operated steering, opening doors, a V8 engine and a lever inside that opens the bonnet.
On paper, this is the least risky library addition. It is an adult-targeted car at a size that can be built without giving up the whole weekend. The black and silver livery also gives it a different character from the modern supercars.
The limitation is scale. At 29 cm, it will not have the gearbox density or display presence of a 1:8 car. That is fine if the build is honest about what it is. Not every Technic car needs 3,500 pieces. The verified specification is on LEGO’s Ford GT40 42223 page.
NASA Artemis 42221: the mechanism I want to try
The Artemis rocket is 632 pieces, £54.99 and 70 cm tall. Turn the hand crank and the model demonstrates three stages of separation, including the solid-fuel boosters, core stage and upper stage with Orion.
That gives it a clear job. It explains a process through one connected mechanism. LEGO developed the set with NASA and the European Space Agency, and it includes four astronaut nanofigures.
It is aimed at builders aged 9 and over, so it will not replace a flagship car for difficulty. I am interested because it broadens the library and gives a younger builder something mechanical to demonstrate after the last step. The official Artemis 42221 page has the current price and specification.
What I would add first
For the main library, the Koenigsegg and Aston Martin have the depth our experienced builders ask for. The Ford is the practical smaller addition. Artemis is the one I would choose for variety and shared building.
The Tumbler needs a different test. Before I put an app-controlled set into regular rotation, I want to know how the battery, charging, firmware and app behave across repeated dispatches.
I will update this list when LEGO confirms another UK release. Until then, those are the five current sets I think deserve a decision rather than another round of generic praise.
