This is definitely the MOST complicated and challenging build that Lego technic has made. I have built several of the tougher ones like the rough terrain crane as well as the liebherr excavator and several more big ones. This one however tops them all and will be a completely worthwhile build. I know the price is a lot but you get something that is perfect in every needed way. DO NOT pass this one up.Not for someone who has just gotten into technic and only for people who are really patient and careful. 16 and up only

Words of my husband:Though expensive, the Lego Bugatti is a joy and experience to craft and build if this duplicates automotive engineering than both the car and Lego designers are pure geniuses, and you learn to respect the design as you build. This is a fun project to zone out on and do a couple hours at a time here and there. The packaging itself is pristine and professional, everything is arranged and categorized beautifully to where you can plan it out. Without spoiling too much, there are two! manuals to building this beast! And the manuals themselves are full of photos and art and footnotes from the designers. Though the exterior is very flashy, my favorite parts to build were the engine, vastly complex transmission, and gearbox and the way these all fit ... MoreWords of my husband:Though expensive, the Lego Bugatti is a joy and experience to craft and build if this duplicates automotive engineering than both the car and Lego designers are pure geniuses, and you learn to respect the design as you build.

I rarely had trouble or difficulty, but definitely check twice before connected measure twice, cut once, as a previous reviewer said as there were a couple times I had to retrace my steps the car is designed as some parts you make at the beginning will have no purpose until later, and it is just MAGNIFICENT how they all fit together purposely. I also had no missing or flawed pieces, my kit came with about 20 extra pieces actually! Probably a later print. I really enjoyed my time with this, something best done late at night with some vibey music in the background, unwinding from work. 10/10 recommend, would buy again! I intend on checking out the other kits such as the newer Lamborghini, the Porsche, or the Land Rover.

Entertaining Experiance

This project was fun and challenging to build. Hats off to the Lego design team. When building the gearbox make sure to leave a little spacing in the gears, placing them too tightly together may create excess friction in the gearbox and drivetrain later in the build. Building the back half and the front half of the chassis is a unique idea that works well. I found it took some patience and accuracy to align the various axels and drivetrains in order to put the two halves together. Once the two halves are together it is a good idea to put the rims and tires on the chassis to test out the gearbox, if you have made an error in assembling the gearbox or the drivetrain it is easier to correct the problem at this point. After performing the check you can remove the rims ... MoreThis project was fun and challenging to build. Hats off to the Lego design team.

After performing the check you can remove the rims and tires and continue with the build. A known problem with the Chiron is a soft suspension that has been described as not fully returning to the start position when the car is pressed down. It appears to me that the cause of the problem is that the suspension geometry in the design does not allow the springs to be compressed (loaded) sufficiently as installed. Fortunately there are several solutions that are demonstrated on YouTube if one wants to check them out. I used the zip tie method to fix the problem with great success. Finally I would like to recommend that you take a listen to the podcasts and check out the video of the Lego crew building and testing the full scale model of the Chiron, very cool! Cheers.

Excellent model of an awesome car.

This is an amazingly detailed model, faithfully recreating numerous iconic aspects of both Bugatti design in general, and the Chiron in particular, including the horseshoe grille, the sweeping exterior curves, and the custom pattern wheels. The build itself is rather long and involved, taking me almost twelve hours over the course of two days, though much of that time is spent assembling the rather robustly designed frame and undercarriage and the intricately modeled seven speed dual-clutch transmission and monstrous 8 liter W16 engine. However, despite how complex the build is, the instructions are well designed and mostly pretty easy to follow barring a few places where it's easy to miss small pieces being added to much larger assemblies.The transmission in ... MoreThis is an amazingly detailed model, faithfully recreating numerous iconic aspects of both Bugatti design in general, and the Chiron in particular, including the horseshoe grille, the sweeping exterior curves, and the custom pattern wheels.

However, despite how complex the build is, the instructions are well designed and mostly pretty easy to follow barring a few places where it's easy to miss small pieces being added to much larger assemblies.The transmission in particular is extremely impressive, both the internal gearing and the shifting mechanism make inventive use of individual pieces to produce a remarkably complex and thoroughly robust system. It's honestly a bit of a shame in my opinion that there's no way to see most of it once the model is fully assembled.The design is rather sturdy (more so than I would normally expect for a LEGO model, though this is the first Technic model I've built that's on this scale), though some of the exterior modeling is a bit less robust than I would personally have liked if I hadn't bought this as anything other than a display model. The detailing relies heavily on carefully placed stickers in some places, which I'm not hugely fond of but can understand given that custom printed parts would have significantly raised the price of the model.Overall, this is a great model for the value, especially given the history of models like this becoming valuable collectibles once they're no longer being produced. I would highly recommend it for both fans of complex LEGO sets and fans of sports cars.

Great Model and a Feeling of Accomplishment

Having built the UCS Millennium Falcon some time ago, I was ready for another challenge and this model has become my favorite Lego build. While working on it I was inspired to learn about the real Bugatti Chiron and I was blown away by all I learned, from Buggati's history to how the vehicle is assembled and it's capabilities. The car is an engineering marvel. As I proceeded through the build, I could see the level of detail that the Lego designer put into this model. The bags are numbered which increased my enjoyment. However, after the "marriage" part at stage 6 I tested the wheels by spinning them by hand and noticed they would spin only a turn or two and then stop. I disassembled most of what I completed and located that my mistake was in the gearbox with the ... MoreHaving built the UCS Millennium Falcon some time ago, I was ready for another challenge and this model has become my favorite Lego build.

The car is an engineering marvel. As I proceeded through the build, I could see the level of detail that the Lego designer put into this model. The bags are numbered which increased my enjoyment. However, after the "marriage" part at stage 6 I tested the wheels by spinning them by hand and noticed they would spin only a turn or two and then stop. I disassembled most of what I completed and located that my mistake was in the gearbox with the orange pieces that engage the various gears. I didn't have those orange pieces sitting correctly so there they would be able to engage the gears. Based on some similar problems I've seen builders have on YouTube who unfortunately discovered a problem with the wheels not turning after the model was completely finished; I recommend testing the wheels to make sure they spin after the marriage where you join the front and rear halves of the model. The wing was also a bit of a challenge for some reason, but it ultimately came together perfectly. My second suggestion for builders is to take their time and enjoy the process. I've seen several videos where people try to rush assembly and ultimately make a mistake. Even with my mistake this was a great experience and I enjoyed putting the model together and learning about the real Chiron. The model looks great and the more you learn about the real Chiron, the more you will appreciate what went into designing this piece. I enjoyed the Chiron so much, that I ordered the technic Porsche which I had to get from a third party because it is a retired product. From what I see, the Bugatti blows the Porsche away, but I got addicted to the engineering that goes into these models.

Lego Chiron - a marvel of lego design

The Lego Bugatti Chiron is a fun, intense and rewarding build - even for a seasoned technic fan. It is a very impressive design, so I can only express my admiration for the lego designers who made it happen. I am still amazed at how they incorporated so much mechanical functionality into a finished product that looks great. If I tried to design and build a Lego car with those functions I would probably not succeed, but if I could, I am quite sure that the finished product would not look amazing like this. Well done to the lego design team!The W16 engine is very well done - even if it was not possible to configure all 16 pistons to be reciprocated by a common crank shaft like in the real car. I am impressed with how the designers still managed to make it work within ... MoreThe Lego Bugatti Chiron is a fun, intense and rewarding build - even for a seasoned technic fan.

I am impressed with how the designers still managed to make it work within the limitations of the available lego parts. The 8 speed paddle-shift sequential transmission is also very impressive, particularly at how densely packed it was, for the gear box to fit it underneath the engine. The all-wheel-drive and independent suspension on each wheel was also very well done.The building of all the bodywork around this mechanical marvel is a detailed and obsessive effort by the designers. In the end, the car looks amazing. The interior is great too. I only wish I had x-ray vision to be able to enjoy watching and marvelling at all the moving parts inside!Having built more than 30 of Lego's technic sets and plenty of other non-technic lego sets (including the bucket wheel excavator, the rough terrain crane 42082, the Volvo front-end loader, the Mack truck and the mobile crane 42009), I think the Chiron is the most impressive and accomplished lego set released to date. Anyone who loves technic lego will appreciate how much of a design feat this car is. Anyone who has never worked with technic lego before is in for a treat. Enjoy!

Mixed bag

The COVID lockdown and disposable income has spurred me to get back into Lego because I always enjoyed the technical aspects of Technic builds when I was younger. I purchased the Chiron kit because I was really excited by the details of the transmission in particular. I found that part of the build to be really enjoyable.I have a few critiques of the build as a whole in its final configuration:1) The model as a whole is pretty flimsy. Picking it up feels like some parts are liable to fall off at the slightest touch- this is particularly the case in a couple of corner bricks under the spoiler.2) The excellent functionality of the transmission is marred by the wobbly wheels and brake calipers. If you try to move this on the floor to see the engine/transmission ... MoreThe COVID lockdown and disposable income has spurred me to get back into Lego because I always enjoyed the technical aspects of Technic builds when I was younger.

Picking it up feels like some parts are liable to fall off at the slightest touch- this is particularly the case in a couple of corner bricks under the spoiler.2) The excellent functionality of the transmission is marred by the wobbly wheels and brake calipers. If you try to move this on the floor to see the engine/transmission in action, I find the calipers rub and get stuck on the wheels and fall off, and can be quite challenging to re-attach. This occurs both because of the weak attachment of the calipers and because of the wobbly wheel mounts.3) The wobbling of the rear wheels on my model pulls laterally on the axles slightly, which can pull them out of one of the small gears in the rear differential and allow it to fall out. Replacing it requires inverting the model, which then causes other bits to fall off. Luckily, this differential is accessible (by design?). If one of these gears fell out of the forward differential, fixing would require a near-complete dissasembly.4) The above problem is worsened by the weakness of the springs in the suspension, which has been noted in many reviews. The weight of the model means that these springs are constantly compressed beyond their limits, and so the model sags a bit. In this position, the axles (again particularly in the rear drivetrain) are more liable to be pulled out of the differential, dropping the gear out.Overall, I am very tempted to disassemble the body of the model and leave it mainly as a frame with the engine and transmission exposed. The mechanical guts of the model are by far its most interesting part, whereas the bodywork is much less detailed, more flimsy, and adds considerable weight.It's a fun, challenging build, but I think the post-build enjoyment of future such models would be improved by addressing some of these issues.

Much more rewarding than I'd expected!

I've built a number of the vehicle Lego Technic sets over the years, and had been aware of this set for some time, (a couple of YouTubers plugging it helped) but funds did not allow so I'd been keeping my eyes open for a good deal and (against my better judgement) found a brand new unopened set for a 1/3 under list price from a private eBay seller. Slightly relieved to receive something exactly as described I was eager to commence building the day it was delivered.The presentation of the set isn't quite as impressive as set 42115/Lamborghini Sián, but it's still well presented and had a premium feel to it.The build felt much more complicated than I'd anticipated, the W16 engine was a bit of a cop out (it's a V8 with a straight 4 bolted on either side, so 3 ... MoreI've built a number of the vehicle Lego Technic sets over the years, and had been aware of this set for some time, (a couple of YouTubers plugging it helped) but funds did not allow so I'd been keeping my eyes open for a good deal and (against my better judgement) found a brand new unopened set for a 1/3 under list price from a private eBay seller.

I thoroughly enjoyed building this, it is certainly the most technically challenging set I've built to date, and although I wasn't overly enthralled with the end result it has (after about a week) certainly grown on me. This is nothing against the set, I'm just not a Bugatti fan.I made the decision to polish certain pieces that were of a matt finish compared to adjacent pieces and am pretty sure that that effort enhances the end result well. I very much appreciate the way the build was broken down into boxes and numbered bags, and found the instructions to be pretty good, some things could have been a bit clearer, but I did some of this late at night so lighting and tiredness could account for some of my confusion. I was a little confused as to how the rear wing would be operated until very near the end of the build, the handy tool for adjusting it you get to build also doubles up as a sign for the piece whilst on display, and can also be stowed in the 'frunk' if you see fit.Overall this is a very rewarding build, and worth every penny, if I'd have paid full price I'd still be very happy with the end result, it is definitely the pride of my collection. This is probably the most challenging and rewarding set I've experienced to date.

Only the most expensive is good enough

Introduction:As part of the 'Super Car' family, Lego sure gave the Chiron the VIP treatment; very big and very expensive.Building Process:Just like the real Chiron, this Technic set did a very good job recreating the building process, the 'marriage' process is especially well done, is a quite an accomplishment when the two halfs of the car comes together and all the axels and gears connects perfectly.The builder will spend about 80% of their time building the internal structure of the car, and is a trully beautiful thing to watch the car taking shape piece by piece. The transmission is the most complex part of the vehicle, is no small feat for Lego to design such intricate structure within the space available, enjoy the interactions of the gears while you ... MoreIntroduction:As part of the 'Super Car' family, Lego sure gave the Chiron the VIP treatment; very big and very expensive.Building Process:Just like the real Chiron, this Technic set did a very good job recreating the building process, the 'marriage' process is especially well done, is a quite an accomplishment when the two halfs of the car comes together and all the axels and gears connects perfectly.The builder will spend about 80% of their time building the internal structure of the car, and is a trully beautiful thing to watch the car taking shape piece by piece. The transmission is the most complex part of the vehicle, is no small feat for Lego to design such intricate structure within the space available, enjoy the interactions of the gears while you can, becasue once the body panels are on you will never see those gears again, and this is one of the down sides of the recent 'ultra' realstic Technic sets.Features:Cars always have a special spot in Technic history, the Car Chassis, Test Car and the legendary 8880 Super car were all technological marvels at the time, each one packing more features than the last, however the reccent 1:8 IP/OEM car line seems to be going on a different direction than before when it comes features and functions.For a flagship Technic set such as the Chiron,one would expect a lot of functionalities from all those (3600-1) bricks, but the result seems a bit lacking when you compare to super cars of the past.The car comes with 4WD, working steering, pedal shifters with 8 gears, and last but not least the adjustable rear spoiler. Impressive as those features are, nothing is trully revolutionary, you would think for a super car such as Chiron there would be at least some kind of power function/lighting effects support, not only there is none it doesn't even have a door latch, is a huge step backwards as set as old as the 8448 Super Street Sensation (1999) even had spring driven doors!Overall Impression:With everything been said, the Technic Chiron sure looks great upon completion, however aside from sitting on a shelf or inside a display case, its complex gear box and mechanisms won't have much chance to demonstrate their interactions under 'play' condition, as most of the gears are covered under the intricate body panels, unless you are using a power function motor and the speed computer, you won't be able to tell which gear you are in, and whether the car is in Drive or Reverse(it doesn't even inlude sticker for the drive mode lever!).When a Technic set lets you build a completely usless mini handbag with the OEM logo and a fake 'Top speed key' to open the rear spoilers, you know this is no play set, but rather an expensive 'luxry' decoration for your room. The included Technic functionalities are more likely just used to justifiy the hefty price tag, rather than add play/education value, this set is way too big and heavy to be played, even if you do you will get no satisfaction by just rolling the wheels and see almost nothing moving inside.I appraise the Chiron's design and the efforts that the design team put in, however I do not like the direction Lego is taking with the flagship Technic Super Car series. Is becoming more like an IP/OEM showcase rather than technological testbed, looks are everything and functionalities comes second, you are paying more for the brand than actual play experience.If you ever had the chance to build the classic Super Car sets like the 8865, 8880, or the 8448, you would understand where my frustration is coming from. I know Lego's goal now is to make profit, but it shouldn't make its flaghsip sets as luxry goods, is just a betrayal to the Lego name, you should be able to play well without a heavy cost.

Wanted to love it

I’ll start this review by saying the the presentation of this set is nothing short of phenomenal. Everything from the way the boxes form art to the drawings of Bugatti’s heritage on the inside of the top half of the box is absolutely gorgeous. This set is 100% magnificent to look at.As for the build, I was looking forward to building this set with my days off of work but I was halted due to a missing piece in only the second box (of six). Hard to believe that with a set this expensive, I’m still not receiving all of my parts in their respective bags. Missing pieces are always a major disappointment for me because I’m not one of those people who have a big bin of Lego pieces they can go dig through when something is missing.

Missing pieces are always a major disappointment for me because I’m not one of those people who have a big bin of Lego pieces they can go dig through when something is missing. As much as I’ve been enjoying the build I am now saddened due to my inability to continue.Building this set is fun, intricate, detailed, and most definitely a challenge which I welcomed with open arms. Th instructions are done to the best of Lego’s ability which unfortunately can still get a little confusing at times. If you do happen to make a mistake, one little piece misplacement can easily set you back at least a half hour if not more due to the difficulty of separating Technic pins and just the overall complexity of the set itself.So far I was loving this set, I’m disappointed I can no longer continue at the moment until my missing pieces get resolved. I look forward to completing it whenever I next have the available time to do so as this set is a lengthy build for sure.Three hundred and eighty dollar set... missing pieces, quite disappointed.
