Thank you all for teaching me the difference between V and W engine types. I'm more into LEGO than into cars, so i made such an obvious mistake :D

“I would recomend both of them” My wallet: “Bruhhhh”

This is the exact kind of comparison video I was looking for!

dont know if you know this, but if you turn the key on the bugatti a little more, after it rises, the spoiler adjusts itself in the correct and real position(like in the real car) . you have to turn the key with a little more force

Basically andrew tate vs Logan paul

3:14 This is engine W16

The Sian is most definitely better, but if Lego did a redesign of the Chiron, I think it would be just as good

The Lambo is a little more technically sophisticated but I like the look of the Bugatti much more, so that's what I went with.

Lambo: V12 Buggati: V16 Me: Triggered because the Buggati is a W16 engine

For a starter technic set with a gearbox and firing pistons, I recommend the Ducati panigale v4r as it’s not as complicated but it’s gearbox is just a smaller and more simple version of these, but is the same idea. Also it still looks super awesome

Perfect video I was expecting a video like that. Well done!!! :)

Niiiiccceee. Just picked up the Chiron from a 41% off Amazon Prime Day deal - looking forward to building it soon!!!

I'm half way on Lamborghini, just started book 2 and after 2 days I can say I'm tired 😅

I got one for my birthday, then I woke up

Amazing video! I just picked up the Lamborghini today at my local LEGO store, super stoked to build it!

Me seeing both cars: The lamborghini has more features but the buggati is my dream car. Me deciding: Its the buggati... its all about the wheels man

The chiron has a w16 not a v16 Engine but very cool video

Buggatti has a lil bit more good looking box and its probably more known and kinda fancy, while Lamborghini was very simple just green all over and with a bit more features, my choice is probably Lamborghini

Both sets are great but I am more into Bugatti so I got the Chiron!

The Bugatti’s interior is better in my opinion

I have and love both of these sets!! Already can’t wait for the 2022 Technic supercar.

I miss the Porsche in this comparisson which was the first in line of these three. The Porsche also was a masterpiece in my opinion. Also that box was to good to touch ;-)

I only have the buggati but it is still a great set but at the same time I have the defender to make up for the Sian along with many other large technic sets

I hate the adjustable mirrors because they always move around and then you gotta put it back I can’t wait to get this set sometime

I learned much more about car functions after i purchased a lego technic

I have the Chiron and judging from the video I think they're both great but the colors on the Chiron look so much better

I picked up the Sian as an Xmas present but I treated myself before Xmas to set 8865, I got 8880 back in 94’ so I was very keen to see how these old school originals compared to the new breed of super cars, I do still prefer 8880 over all of these and it’s funny how 8865 is completed in around 30 steps where the Sian is almost 1100 steps, I’m not too mad on the Porsche, but the Daytona looks incredible, shame it’s just a basic RWD and engine gearbox set up

At 6:51 the firs light on the left has the pyramid wedge the wrong way round.

When I was a kid I was so into Lego but now I've kinda lost interest, the technic supercars jus look so coll though. I prefer the Lambo its just more refined and I like the door mechanism. Its sooooooo expensive though, for the money I could buy the new iPhone SE!

That lambo was new type of technology to Lego in my eyes

I like the Chiron more!👍

Instructions unclear, bought the UCS Falcon instead Cool video btw

I have all 3, they look so good together because the colours just pop like mad, I was gonna say it’s a w16 not a v16 but looks like some other people have already commented on that

I'm working on FatBoy as of now. After this vid, I think Sian will be a better choice for my next step, but why the color I know not :/ Sian's functions are modern, but Chiron's color takes advantage.

Looks like Sian has a lot of improvements vs. Bugatti - probably due to 2 years work of lego.

Its so annoying when the stickers just stick to itself and gets wasted but we dont have to worry about that in Sian now!

Dobrý den, už dlouho Vás sleduji máte hodně dobré review, už těším se na srpnové sety.

It different to the. It look the same but it have different gear box and design and box is a masterpiece of lego

Time to get one and be broke!

Just got the Sian, still preparing mentally for the build lol

The functions are better on the Sian, but the looks and colour has to go to the Bugatti. Considering this is going to go on display in my room, I might as well go for looks. Bugatti imo

Thanks! Now I know which set to ask for my birthday!

The Sián's interior is supposed to be orange... unfortunately they made it lime instead. Also the whole color is way brighter than the real car...

I have the Ferrari Daytona SP3, and have come to realize that it’s the only one without 4WD 😢 (Still an awesome set though)

Did u spend 9hr non stop filming u build? If yes I respect u bro

Which one do you like the most?

I've just finished building both and I'd definitely say the lamborghini kit is better. That being said they're both incredible

Every one is prefering the look of the bugatti but I think the lambo looks better because is just cooler and more stuning

The designer of these cars are crazy

The thing is about the chiron is that it doesn't look like the real car, while the sian look like the real car more than the chiron look like the real car, but the sian have the blue connecting pieces all over the place making the color a bit off, but the blue connecting pieces don't really appear on the chiron because it's blue so it looks like a part of the car color.

Awesome! Now, waiting for the comparison between the Lamborghini Sian and the new Ferrari Daytona SP3…

3:09 was meant to be W16

Lambo is the best technical car. It does more than all the others.

Great video bro, I own the Bugatti but they both look great!

I think I like the overall look of the Bugatti more, but the Sian has much better functionality in my opinion, such as the raising and lowering of the wing, the paddles being up by the steering wheel where paddles actually are, the suspension, and the exposed gears on the bottom. Everything about the LOOKs of the Bugatti are better I think, including the box, but the Lambo is better for function. Also, the seats in the Bugatti look very uncomfortable.

One of my closest friends has both these sets, including the LED light pack installed

I like the both of them Bugatti Chiron and Lamborghini Sian

Did you know you didn’t open the chirons rear spoiler fully? this was an excellent comparison vid btw

Makes me want to build my Chiron. It’s been in the box for two years. I’ll build my Sian first if it ever gets here.

Want to get one of these. Is there any sources (Lego or third party) that make motors and controls for these?😮 Also, great comparison video!

I might be biased cause I have it but the Chiron does look better in my opinion. It's curves are more distinct and make it more recognizable with the lego approximation whereas the sian had more subtle curves that are harder to bring out with lego elements. Plus the two kinds of blue make it stand out.

I think it's pretty obvious which the winner is.

The Bugatti has a w16 engine not a v16. The bugatti line (around the door) isnt shaped correctly in your build. The bugatti's wing (spoiler) has 1 more stage if you turn it more then you did. ALSO, These arent UCS sets. There just known as the Technic Ultimate Series. TUS not UCS

I couldn't decide so I got both. Built Bugatti, building Lambo now. So far the Lambo is the more challenging build for me. I like the way the Bugatti looks as a finished project better, but the Lambo is more technically sophisticated Edit; just finished the Lambo and it took me just under 12 hours. I made a mistake, forgot a piece completely unnecessary to the mechanism and the build but had to take it apart to put it in there. That cost me a solid 50 min as it was wayyy inside by the differential. It is amazing set, a grueling intricate build where if just one thing is off, it all fails, and you can't fix anything without taking it all apart. Luckily I got the gears and mechanism to work first go. I'm disappointed in the colors. There's all different shades of lime green for the plates which just takes away from it's overall beauty. A shame really. On such an expensive and well designed set. Also, I ended up liking the lines and finished product of the Lambo more, but that's just personal taste.

Nice video, thanks for sharing!

You are the best lego revewer.

Very nice video! Thank you

Dude...you taught me more about these cars than the manual, I had no idea about the spoiler nor gear boxes or door method of opening on Sian!! lol ty!!

I more like buggati because i loved when i was children. My favourite car.

Do the transmission modes work? Awesome vid.

The Chiron set is already complicated to build but guess what, this new set has more pieces that the Chiron. Ah well...time for another hellish lego building

Did anyone else see one of the light pieces placed wrong

I really want the Sian but I can’t afford it and I really want it so bad because Lamborghinis are my favourite cars I hope to work for them one day but I cannot afford it

Hype Train for the 2022 Technic Super car!!

I actually want the bugatti cause I kinda like it more but after this vid idk what to get, especially since the bugatti is about to be a discontinued set

Can please everyone add your own build time for these sets in a reply? Just as a survey and reference point for others. I'm looking at 0:50 and wondering: if I was building the Land Rover Defender for 10 hours, probably I would be very far from ATBT's time with these supercars. :)

I’m getting the Sian if I graduate middle school

I have both of these I finished the Bugatti today in 3 days but the Lambo took 7 Although I couldn’t remember building the Sian’s gearbox Hmmm

honestly, i like the sian more

I have both of them, but Lamborghini seems done a bit better.

not v16 engine only w16

Am i the only one that wish they would find a way to put actual glass windows in these things?. or at least plastic windows. Not to mention put actual light kits in them, kinda sad that we have to buy light kits on the second hand market.

"build time : 9hrs 30mins" Me: 3 hours everyday , for a week and a half

Lol, is the 50 shades of green joke so obvious???

Like your description

I have them all(the porsche,Bugatti chiron and the Lamborghini Cian)

Nice video!

2:59 W16 not V16

You assembled Sian in 9.5 Hrs... That is like Pro. I built in 2.5 hrs... Assembly hr itself took about roughly 15 - 16 hrs.

Am I the only one who really struggling with the stickers here?

Built the Bugatti and its reintroduced Lego to me as an adult, I’m now after the Sian and the Porsche, just got Dom’s charger for my birthday and done nothing but change it. I keep reading that people are disappointed with the green? Understandably it’s not for every one but I personally like the bright colour choices for the premium sets. I won’t lie though it took a while to grow on me lol.

I think I got lucky because my lamborghini is mostly one shade of green

blue technic pieces in Lamborghini look really bad because the car is green, Bugatti doesn't have the same problem

Build time:9 hours 30 minutes Meanwhile build time for me:22 hours 50 minutes Im 12 and new to Lego Technic sets so yeah

The Sián FKP37 definitely 🔥 I copped mine at Christmas 😀 Love the video 👍🏻

My favorite set is bugatti chiron

Cool cars got there

Please do comparison of internal functioning parts

Have bugati and is really happy with its design, also the engine is a w16, not a v16.

In the Bugatti Chiron the engine is a w 16 not a v16
