LEGO Technic 42172 McLaren P1 detailed building review pt 1 - unboxing, 7 speed gearbox and more! 

The set will be released on August 1st for 450 EUR/USD, more details on the official product page - bit.ly/4bFvCmx

I have mixed feelings about this set. I absolutely love the complex gearbox, as it is a refreshing new gearbox compared to the same gearbox we saw in the Lambo and Ferrari over the past 4 years. In the photos, the headlights looked weird, the angles seemed off, but in person seeing it in this video, the angles look really well and while the headlights still look weird, they look better in person because of the shapes I didn’t notice before. Thanks for another great review as always!

I know some people complain that it isn’t a new McLaren or the F1 but I personally love that they made the P1. It’s where most of the modern design language of McLaren came from with the curves and design. It’s also a part of the holy trinity of hybrid supercars that many people still reminisce about today. Maybe in the future they’ll make a 918 and a LaFerrari so that we can have the full trinity in LEGO.

@6:00 "How many colors do you want to put in?" LEGO: "Yes"

She's a beast. Long live this 1:8 ultimate car series. Keep 'em coming.

People trashing on some areas but LEGO sets are subject to intense scrutiny around sturdiness of connections, ease of build. Cant build it like you would a moc. I think the set looks fantastic all round and cant wait to own it

i love all the curvatures from the side profile and although I was a bit sceptical about how the roofline looked on promotional photos, now I can see that it looks amazing. Honestly this is the first 1:8 scale lego supercar that I might be interested in buying. Of course if I had the money.

The looks are take or leave but I really really love the inner mechanisms of this.

I love the mechanism of the door, seems more solid compared to Daytona

Damn …. I absolutely love the look of the P1. Lego did an excellent job. This will be my birthday present to myself… Thanks for a great review build.

OMG this gearbox is a work of art!

Front doesnt look like mclaren P1 :(

Love this set, took it to another level for sure. The fact that you can pick it up without something falling off is amazing.

Can't wait, a great Bday Present to myself, and I'll actually be building on my birthday on the 4th!

Szia Balázs! Köszi szépen, hogy már a feltöltésnél beállítottad a feliratot! Várom a második részt a végső ítéleteddel! További szép napot és hétvégét! Üdv, Unoka!

Can’t wait if Lego releases the new RB17 as a Lego set ! 😮

I love your reviews on the technical elements and functionality!

Thank you so much for the review! I’m so stoked about this set, I really want to get it. I think the designers did a really good job capturing all details of the car.

Lego continues to amaze me!!!

The gear box is amazing those Lego workers put on those hours perfecting it

Congratulations on beating me to the review 🤝

I really like this set because go it’s detail and size and how cool the whole process is, which is why I feel this helps not worry too much about the cabin roof, I feel like it shouldn’t be so tight, it looks more round than the real car

Also, RacingBrick, I appreciate how you went over the mechanical aspects as you built it! 🤘👍

Im glad lego is changing it up, I prefer older hyper and exotics.

Very impressed with the technic techniques used in the door to accomplish the angles and the mechanism for the door and wing is really cool. From the press photos it didn't look all too impressive but this video showcasing all the angles up close in the studio makes it look really good. Awesome to see TLG still do the whole unbox experience and the story behind the brand and set in the manual too. I hope we still get these in the coming years, but I think TLG has a rebrand for this line up it's sleeve very soon...

It looks fantastic, i can't wait for te Porsche gt4 eperformance

Honestly, all I want to do is build this set; I don't really want to keep it afterwards. 😊

I gotta say, this is definitely one of Lego Technic’s best sets; with all of the mechanics and systems it is truly a masterpiece, the only downside I see in it is that it costs 450 dollars!! But overall its a great set 👍

YOOO THIS IS MY FAVOURITE CAR OF ALL TIME!!!!!!!! Lol I am happy, but I am so happy to see the P1 in lego form. Just a masterpiece!!

6:00 nice Rainbow

Looks stunning! I don't care of it is not 100% replica, the angles and curves in this model are crazy good!

I don't care about what people say, I love it. This one is by far the best looking 1:8 technic car. And I think it's the most iconic modern era McLaren

Nice Mclaren P720S1

Looks like an engineering masterpiece, can't wait to get my hands on it

Can't wait to own this set. It'll be my first of the 1:8 scale cars and I think it looks incredible. Great video, cheers!

I used to have a rc p1 toy car and dreaming that in the far future, i will design one for lego, but now, they've already made it!

I've been waiting for this review

This build is insane, I need it.

Looks spectacular, and nicely detailed at this scale. Really like the new piece for the A pillars. Finally a change up from the always familiar flexi tubes that make up the windshield. Nice also to see no stickers in the set. Looks really time consuming to build though.

Try searching for Bruno McLaren P1 on RU-vid. His design for P1 front is much better than this official Lego set.

those beeching about the front are a bunch of nattering nabobs. i myself am impressed since the designers took restrictive Lego panel shapes and managed to capture most of the highly curved panelings and surfaces of the car. i can’t wait to own one.

I have a Porsche 🟠, Bugatti 🔵, Lambo 🟢, Ferrari 🔴and I am already looking forward to this great McLaren P1 🟡

I really wish Lego would’ve made it in purple. I loved the P1 in purple with white wheels! Great pre view but I’ll wait for your thoughts in your next video. To see if it is worth getting!

레고 테크닉에서 전기차 E 모드를 구현할 수 있다는 게 새롭네요

Seeing the new gearbox is already irresistible for me to own it. The side doors look much sturdier than Daytona, which is also good. I will be patient enough to wait for a better bargain to own one.

Fantastic technic set, and those front end looks better than the photos

In terms of looks it is on par with other lego technic sets IMO. The front almost looks like a 12C but the rest of it definitely looks like a McLaren P1. The technic sets are never perfect but they alway get very close The p1 is probably my favorite McLaren anyway so i dont care that they picked an older model. It looks better than a 720(and its variants) IMO

To me it looks fine. They did the best they could with the front lights, and it looks pretty accurate ti me

Bright light orange is my most favourite lego colour.

Can’t wait, am ok with the P1.

Are the large and stiff shock absorbers really just the recolours? What if there is a different stiffness.

i think mclaren may have delayed the launch of the p1 successor to a later date which meant lego had to choose a different car to make which is why the set was delayed

The wheels look gigantic. I’m sure it’s a visual thing and it’s fine in hand but it almost looks like they took a hot wheels cast and built off of that

Purple technic car had me rolling on the floor

This might be my favorite lego technic car ever 😃

They have done a great job with recreation of P1 curves which is not a simple task. I think this is the best looking car out of all sets from this series and the build process looks fun with new parts. So tempted to buy it now.

Oh how I’ll enjoy this when I get this set. (I built the Bugatti in 2020 and it took me 4 days, but it was very rewarding. It’s about time I get another 1:8 scale hypercar

Man that gearbox is so cool and maybe teaches some things as well. I might have to get this eventually especially if it goes on sale.

I hate the use of rubber bands in these high price builds. They degrade over time way more compared to the other pieces....

I love this set and will absolutely be buying it. I wish they did the wing in black though to make it match the actual car

I loved the "big purple Technic set" joke! 😂 12:00 I'm sure many people won't understand your sarcasm and will think you're serious 😅 Anyway, I don't care what haters say: I think it looks glorious 😍

This sets up an opportunity for the holy trinity.

LEGO FUTURE IS THIS !!!!!!

For me the headlights does not look close to the real car, but still a good build

It won’t be long until a tutorial on how to fix the front of the car so it ACTUALLY looks like a P1

I think this looks awesome. Lego technic has done a good job replicating the curves of the real car. I don’t mind the headlights, I think they look pretty cool. the only part I am a bit unsure of is the height of the a pilar. I think it’s a bit too tall and makes the the windows look a bit too big. but overall I love this set

even if it's a little dated, I'd say that model of car is one of the most iconic looks for the McLaren brand

this set looks iconic just like the real thing. a step forward from the daytona imo.

Excelente reseña!!! Primera vez que sigo todo el proceso de un set de este tipo en una reseña.

Honestly, the ads made it look bad, but with your take I might pick it up!

seeing all the new mechanical parts just make me want LEGO to do parts packs again, not full sets, just parts pack so you can just get the new parts on their own

They did the P1 because McLaren doesn’t have a new halo car in their lineup. And don’t come at me saying the solus gt. They’re building 25 of them, they’re track only and will never see anything outside of the owners garage. They could have done a senna but a technic senna gtr was only released not too long ago and even that car doesn’t carry the prestige that the P1 does. Not to mention the P1 replacement is still 2 years off at the least.

I'd love to see a comparison with the little 6-wide Speed Champions McLaren P1 from the very first wave, which coincidentally has the same colour. I know it's an oldie and the shapes aren't really there, but I'd still appreciate to get a good side-by-side look :)

Love it, looks awesome thanks!!!!

8:35 I dont know if you tried this already so my bad if you did, but I like to kind of twist those types of pieces in, like a screw almost, when it's tight like that, it usually helps me get it in. Also, I am absolutely getting this car, what an amazing amount of functions and it looks to me, really stunning. Great video, I am still new but loving this channel!

Looks like a really cool set and lots of cool new pieces. It's just a shame they did the P1 instead of the legendary F1. But I suppose that's where the fun world of MOCs comes in.

This is definitely the best supercar so far. We've finally got the right parts for bodywork and the right parts for the transmission. I wish the interior weren't black, but eh, it is what it is.

Just finished the gotham city set for my wall. I think im gonna grab this next.

Someone needs to get Tavarish one of these so he can have a finished P1

OK weird looking car, not a fan, but on the other hand… your opinions and detailed reviews are much appreciated!,

i want you to compare this to a nice diecast metal model, cause lego is cool, you can build it, but diecast is smaller cheaper and more accurate

Love the doors, but why the P1? A has-been supercar if there ever was one.

Can’t wait to buy and build it!

oh i love it! its everything i hoped it would be. im definitely getting this one on day 1. and i definitely think this one will have fantastic mocs. lets hope jamesJT will get this one too :)

I have been waiting for a 1:8 scale McLaren and dang it's awesome. though not my favorite McLaren (the 570S), the P1 is quite a good choice, and they did an amazing job

Shape looks accurate enough. Would get it if I was a fan of the P1. I agree, weird choice for the McLaren model to go with.

It's nice. But I think the wing mechanism could've been better than turning a gear. As always, your builds and opinions are greatly appreciated.

i wish they used the huracan technica exhaust part on this car in the grey system build it would look so cool

It may never happen but I’m dying for an AMG GT Black Series

You asked not to compare it to the MOC, but I have it (and 100% real lego as well, made with instructions from the designer). I'm a BIG McLaren fan. So this one will be added to my collection at some point (but not at the release price). The MOC doesn't have a gearbox. People complained about this, but as others have stated: you won't use it after building. I think for the MOC it is a win. The MOC replaces that with doors that can be opened with gears and the suspension can be altered in height. When doing the suspension manual, it does take some time. I also love that the set is a P1. I would have gone even further back and have an F1 GTR instead ;). I just love the look of the P1 and F1 more than the rest. Although seeing the Solus on Goodwood, I think Lego also could have gone with that. As for the comparison. gearbox vs suspension+doors and I'm sure this one will look more smooth because of the custom panels. And with the different color to the MOC, I'm sure they will look great next to eachother.

I think they went with the P1 because the other cars in Mclarens line up don't have active elements which is what a technic set is normally about. The choice of the p1 over the f1 is probably down to it simply being newer and still being an iconic car.

I really like it. Yes the front is off but oh the rest of it looks so good. I love the colour choice

Wonderful review, as always, Balázs, congratulations! It was a joy to watch it, together with Part2, and basically I like what I see, so now I am ready to buy P1 as my second LEGO 1:8 supercar, after the Porsche. However I have two questions: - Is it correct that this model has no Ackermann steering? I really don't know why LEGO is not implementing this authentic function on their models, it is not that hard, and they even managed to do it in 1980 on the 8860 supercar chassis. And on this year's G Mercedes. - Isn't it disturbing, that you have to pull up the doors directly, as the left out the push botton this time? It is again a function that was "invented" by LEGO decades ago.

You know, I wasn’t a fan of the front, but with the parts limitations, it’s not bad. It looks fairly accurate

I allready wanted to buy it becouse I love mclarens and it will be my first 1:8 technic set I now I like it even more

I'm so excited to get this day one

I've always wanted the 911 gt3rs trchnic model but couldn't get it as a kid and now it's expensive. this might be a cheaper option but still just as cool!

Can't wait for the Porsche set review.

Please make review for jesko absolut, I need that thing for sure!🙏🏻

While this is of course very expensive, I'm glad this isn't even more expensive than the last set! Looks pretty good overall and I'm pleased with this; the choice of going for an older car produced between 2013 and 2015 is definitely odd. Older more classical or legendary cars are typically chosen for Icons/Creator Expert and Speed Champions, while Technic tends to go for current or upcoming vehicles (although Dom's Dodge Charger bucked the trend) The only thing I was worried about was the build itself; the Ferrari Daytona I skipped as I noticed and read that a lot of the chassis and inner mechanics are laid out the same way as the Lamborghini Sian, bar the odd small change in part use here and there (of course both sets were designed by the same person). Even though the Daytona was almost half off, I didn't feel like spending a lot again to build a fraction of the set mostly the same way again. With this P1 though, it's a lot more convincing and seems fresher than the last ones. I might go for it, but with a 50% discount, which has happened to all the last four sets of the 1/8th Supercars as Technic doesn't tend to do well at full price in the UK and itsn't as popular (unless they're heavily discounted which is all the time, after some wait).
