Alexandre Campos has already examined all the new parts in the LEGO® Technic 42083 Bugatti Chiron and now turns his attention to the incredible build process.
As mentioned previously, 42083 Bugatti Chiron is divided into six numbered boxes, each with numbered bags, and this is a godsend. Having to search among 3599 parts at once would be maddening. Some instruction steps are also extra helpful with the build, especially when Earth Blue [TLG]/ Dark Blue [BL] elements are involved: a red outline marks newly-added elements. Still, make no mistake: this is an intricate and complicated build, and often it's hard to know what goes where, and easy to make mistakes.
Near the beginning, what is probably to many Technic fans the highlight of the set is built: the gearbox.
This is a wonderfully complex assembly, and its compactness is made possible only with the new functional elements, especially the wave selector.
You can see how rotating an axle 90º at a time shifts between all the gears. When building this section, it is recommended to pay attention to follow the instructions to the letter – or, in this case, to the image –, as any mistake will be painful to correct later.
The front suspension and forward/reverse mechanism are built next.
At this point, the instructions appear to have a small error: on page 198, step 315, the orange Technic Pin 3L with Friction Ridges Lengthwise and Stop Bush (Design ID 32054) at the rear is shown completely pushed in, unlike the previous and next steps. However, this error isn't serious and you'll probably not notice it.
We now come to one of the set's more unusual parts usage: I don't remember ever seeing all four holes of a Gear 24 Tooth (Design ID 3648) used at once in an official set.
The front and back of the chassis are joined, and from here it's mainly bodywork, again starting at the rear and progressing forwards.
When building the rear details, we come across another unusual part usage: Technic Pins 1/2 (Design ID 4274) are attached to Tiles Round 1 x 1 with Bar and Pin Holder (Design ID 20482) to make what is practically a 1x1 version of the Tile Modified 2 x 2 with Pin (Design ID 2460). These are then used in brick-built details to hold the rear lights.
There's one more interesting parts usage at the rear: a pair of Minifig Weapon Guns, Mini Blaster / Shooters (Design ID 15391) hold the ends of the red rigid hose that represents the main rear light.
This is an ingenious solution, but unfortunately is also the set's structurally weakest point, as they're very easy to pop off with less careful handling.
The rest of the bodywork is then built, and after that, all that's left is the final details.
Finished modelThe Bugatti Chiron isn't my favourite car design, but there's no denying that the LEGO version is a beautiful and faithful rendition of the original.
Functionality-wise, the set has much to offer. The doors and bonnet open manually, which in the latter case allows access to the luggage compartment and the tile with the model's unique serial number.
The car features four-wheel independent suspension, each wheel using two Technic Shock Absorbers 6.5L - Hard Spring (Design ID 76537). Unlike the copies in other reviews, such as by Brickset and Sariel, mine does return up when depressed at the front, yet, not fully.
The car has 8 forward speeds and 1 reverse. These are controlled from the lever between the seats, which chooses between one of the forward gears or the reverse, and the paddles below the steering wheel, which shift sequentially between the forward speeds. I have two problems with this mechanism, although one of them might be my fault. First, the paddles sit so low and leave so little foot space that they might as well be foot pedals instead. Second, all forward speeds spin extremely slowly in relation to the engine, with no noticeable difference in speed between them, while reverse is quite fast. I might have made a mistake during building, but for the time being don't dare to take almost the entire car apart to verify and fix this. Remember the previous advice about taking care to follow the instructions carefully when building the gearbox?
Finally, there's a tool-assisted function. The rear wing can be deployed with the help of the tool shown earlier.
ConclusionThis is an impressive and beautiful set that should appeal to fans of cars in general, not just Bugatti. Technic fans will also appreciate the intricate work involved in having LEGO elements form these complicated shapes, the imaginative use of elements, and especially the complex gearbox. People who like to MOC stuff will also find value in this set, with its plethora of elements in uncommon colours (Dark Blue and Dark Azure) and the gearbox elements, unique at time of writing.
On the other hand, this set's hard-to-swallow price tag ($349.99/ £329.99 GBP/ €369.99) is, well, hard to swallow. The model's weight of almost 3 Kg (~106 oz), difficulty to steer (both in terms of reaching the steering wheel and the turn radius) and weak suspension, make it unsuitable for playing or modifying for remote control. Also, the subject matter's design itself isn't to everyone's taste.
Overall, I'm impressed with this set. The model is beautiful and ingenious, but, most of all, as a MOCer, I'm personally looking forward to the possibilities offered by the new elements.
EpilogueI had on hand one 42054 Claas Xerion 5000 Trac VC, and decided to try swapping wheels between it and the Chiron to see what happened.
