42151 - Bugatti Bolide

[Void_S]

Just to match the real car:

1. The gaps between the front wheelarches and "hood" are here, as they should be.
2. The sides suffer a bit of panels misalignment (some additional micro panels are needed to fill the gaps and finish the lines that are broken now)

The rear side looks authentic but I would put the exhaust pipes a bit upper and with inclined at a bigger angle crossed taillights.

Looks pretty close to me.

New parts are shaped, it's time to start something...

[Jockos]

Somehow I just can't get over why they didn't use the new small wedge panel in yellow instead of black in front of the wheel arches..

Wow, that was really quick! I imagine the small triangle panels just required a bit of trimming, and the angular panel could be stitched by 2 normal ones. But the fender looks a bit more tricky. Any way to get these parts into LDD pack before the end of the year?

Looking forward to getting this set.

W16 is a great feature. Just hope it has a differential.

And best of all it will round out the transporter collection.

It's a full W16, you can see another row of cylinders behind.

I see 8 brown axles as pistons!

He may mean the slightly visible light reflections, possibly from another cylinders row (in green), right under the upper one (in red):

The rear compartment has plenty of free space to fit it.

This may be the only interesting technical aspect of this car...

I made a rough draft of the model and would like to highlight some possible facts (only my guesses, based on the images):

1. HOG steering with non-working steering "wheel" in the cabin. It has EB 1x1 printed tile from the "bigger brother" USC Bugatti Chiron wheel centers.
2. The W16 engine. As I found, this engine (stacked V8 from existing models) still may fit. V8 is a pitty boring alternative...
3. RWD. V8 fits the full-functioned differential, while W16 may require some tricks, as it may conflict with the rear axle.
4. The wheelbase equals 42123 McLaren Senna.
5. Openable Senna-alike doors with inclined hinges.
6. Openable rear "hood" halves, like bug's wings.
7. Frame and body have 1/2 stud drop: the front axle sits in the wheel arches with a decreased upper gap (like 42137 and 42138 do), while the rear axle has a stud-like normal position.
8. A lot of new panels. I will show and render them later. That is only my understanding of them, for sure.

@Zerobricks, I'm not into LDD, sorry... All the things I do, are limited inside Studio and Studio Part Designer. Instead, I can share their .part and .obj files with 3D models.

 

Following them, and their restrictions, I see three possible variants:

1. SAD STORY: Senna's wheelbase (or shorter) + V8 + Diff
2. COMPROMISE: Senna's wheelbase (or shorter) + W16 + Senna's 1WD 
3. ALL-INCLUSIVE: Senna's wheelbase (only!) + W16 + Diff

Renders of my vision of the model (Studio + a few custom-made parts):

Wow, I find it totally awesome how you can construct a model from just a few views - not to speak of sculpting the new parts in no time.

How does the engine work? Does it have one or two crankshaft(s)? I can't really see how it would work smoothly with those 1/2 bushes against the side of the 2L beams (with axle hole) with the injection point - well, I need to build it to see for sure.

[Void_S]

@johnnym, it's my "feature" to spend my waiting time on some tries and guesses. A "constructive expectation", I would call. For 42138 Shelby GT500 it resulted in a "face" somehow not worse than the original one.
The model's file and part sources won't be published until the release date anyways 

The engine may look like that (just @Zerobricks's and my guess, not 100%-proved information):

Each "head" of the well-known V8 has a second layer with additional 4 pistons. In total, we have 16 pistons are driven by a single crankshaft. Being properly leveled, they should make no effort for the crankshaft rotation.

I'd say it looked better than the original one IMO!

Thanks for the detailed picture, I'll give it a try as soon as time allows.

Given that 42132 used the piece 6575 as the cam in the engine, might this engine do the same? I imagine it would be smoother driving the lower bank of pistons.

Seems like Luca already got his hands on this set ;-)

The official review videos of promo accounts can only show it on the 2nd of december. Luca's set "fell off the truck"... :D

Edit:

The working W16 engine is shown at around 52:00!

@Jundis

Thanlks for linking the video.

So the engine indeed uses the TECHNIC cam (@deehtha ). A nice plus is that each 8 cylinder bank is constructed like a VR8 - impressive!

Sadly, no diff... see at 1:52:40 :-/

Well, the engine already takes a huge part of the car. If it would be swappable it would be even cooler...

When can we buy it? Before Christmas?

[johnnym]

@Void_S, @Zerobricks:

BTW your guess was quite close to the original. Absolutely impressive given the quality of the engine photo - which is even mentioned in the video.

I think, due to the really bad quality of the photos, the quality of composition doesn't matter: the lower row of the pistons is barely visible in both cases, and when the "clearly visible" parts are also blurred and darkened, we start clearly see all the things after an hour of staring.

Seriously, my "middle" theory works here (I'm not sure if there is still 1WD or just a "locked differential" that is clearly ommited.

The option with differential is still possible but requires making the engine heads much longer, to mount their rearmost sides after the differential, so the whole engine will technically be placed over the rear axle, but the pistons will be in its front part, before the rear axle.

One more thing, I had some doubts about, and now is clear: it will have a ton of 2L axles in black! There are a lot of axle-mounted combinations around the chassis (all these new panels, yeah) and I didn't and don't now see all these "red plusses" where the 2L axles are clearly placed. So, may the color commit step back here? They were used in minor, when their "appearance" ruined the final look, but here it's not about 2-4 relatively rare (uncommon, at least) colored pieces, but 8-10 or even more.

I love the look of it, the functions, and the new panels. But with your renders it looks like a Technic version of a Speed Champions car, or is it just me?

I think it is because of all these new panels - they are pretty small and triangle shaped, so remind us of sloped bricks and wedges actively used in Speed Champions sets.
At least, such a comparison was slightly possible a few years ago, when only big panels (with big gaps in between) or even earlier flexible axles were only available.

[SNIPE]

I didn't see a differential in the parts inventory (unless its on another page)
