Super Cool 8110

A couple of new high quality images from the upcoming 8110 Unimog U400, were published at Car and Driver blog, likely to confirm us some new details (click on the images to enlarge, or here for an even larger resolution sample from the first picture).
But this is something to return ahead in this post...

Despite these images there are few statements in the posted article, that points towards new informations. Below, those that I found most relevant:
  • It is a 1:12 scale model from the real Mercedes-Benz Unimog. Point here is the scale identification, not that it is a model from the Mercedes-Bez Unimog of course...

  • "to commemorate its 60th birthday, Lego and Mercedes teamed up to create a build-it-yourself version."
    Ok, this model pretends to be a celebration of the real Unimog.

  • "Not only are details such as the engine and hub gearboxes painstakingly recreated with tiny moving pistons and operable gear-reduction systems, but the small rig is electrically driven and sports a fully pneumatic gripper arm mounted aft of a pneumatic “dump” bed."
    One confirmation and something still unknown, here.

  • "The Lego Unimog also sports four-wheel drive, coil-spring articulating solid axles, and a power front-mounted winch."
    Two confirmations here of some anticipated options.

As for the details found in the images above, let's take closer look on the areas highlighted below,

  • Green: I had this suspicion before, but not I'm pretty sure it is confirmed. With 2.048 parts the Unimog should be quite heavy and thus requiring stronger suspension or shock absorbers.
    The spring coils used on the Unimog look different from all those ever released in the previous LEGO Technic models. The coil pitch looks quite larger than usual, likely meaning stronger springs and consequently heavier suspensions.
    Bet it might open some new possibilities (e.g. for the heavier TrTr vehicles).

  • Red: This doesn't seem to match with anything known to date. Maybe a new kind of frame similar to 64178 or 64179. A new C-Shape frame would be highly appreciated and it seems to fit nicely in this application (an articulated solid axle).

  • Yellow: Still quite fuzzy but the hub gearboxes behind the portal axles might be here...

  • Blue: It looks the PF M-motor with its multiple functions. The pneumatic pump seems running from a single pump cylinder!? The only strange thing it is the way it looks positioned. Just behind the motor, i.e. in the opposite direction to the motor shat output...

    Or is it another cylinder for the pneumatic "dump" bed!? Don't think so...
    Also this pneumatic dump bed feature, came to puzzle the way I have imagined the Unimog controls should work.

    Somehow I still doubt on this information about a pneumatic dump bed.

Tires inscription indicates "94,3 x 38R", which would mean the largest in diameter straight tires (non-balloon and non motorcycle) ever released by LEGO.
Just another range of possibilities for larger scale cars, despite a bit inappropriate profile and tread. But surely very useful for large trucks.

There is also a large amount of stickers in this model: some indicators, some warning signals and some ads all around.

For now it seems that this is going to be a great set. Last year we thought that TLC has reached it's pinnacle in complexity; but they seem to top it with this awesome flagship.
Can't wait to get my hands on it and I'm counting days for it to arrive on my doorstep. I've preordered the Unimog for €161,00 so the price per part of € 0,08 is going to be acceptable.

Jetro said...

C&D says 1:12, Gizmodo puts it at 1:12,5 ... it also indicates a US price: ~$250 pretty steep if true!

Menno Gorter said...

YES! Now it's 100% sure to me it has gear reduction on the axels!

Blue circle: definitely the pump cylinder.
It's driven via the red clutch... ;-)

Red circle: if this is a new c-frame it might be a wrong design. At least not the one I desire ;-)

On the first picture under the battery case and behind the front wheel you can see some photoshop activity on the right rear wheel. Probably in order to hide a new part.

I still feel the need to buy at least two of this set.!

stump said...

The three pneumatic switches account for the three pneumatic pistons on the arm. The air is switched between the fornt and rear blue ports from a fourth switch just behind the battery box. You can clearly see a blue hose running to the front and another to the rear from this switch which seems to connect to a centre compressor.
I find the PF gearbox lables interesting;
1 appears to be the pneumatic compressor
2 appears to run the front attachment (winch or blade)
3 appears to run the rear attachement (arm rotation or dumper)
4 appears to run both attachments (curious)
I'll need to build a taller shelf for this one.

Wiseman_2 said...

Looks nothing short of spectacular. I thought last year's Excavator would hold out as my favourite set for a very long time, yet barely a year later it looks like it will be beaten (not that I am complaining!).

The dearth of new parts is also excellent.

One point I am curious about: the switching (driving?) ring and 16-tooth gear located above the motor. Why are they on this side of the vehicle when the switches are on the other side?

Regardless, I want it, and I want it now, and will act like a spoiled child until I get it :P

thirdwig said...

I am really excited to see how the portal axles are done on the front axles. This is a great confirmation. I hope to see the new parts soon.

Ryan said...

is that a new part at the motor side of the model (so with the nose of the model facing to the right)?

There is a part visible looking like this: yet it seems to extend longer into the model...

Jetro said...

It looks like the existing part to me...

Mark said...

its listed here in the netherlands on a site for 154 euros.(this site is usually the cheapest i can find online) Fairly steep price so i think ill only be getting one set.

anyone know the exact release date ?

Povratnik said...

The part that you circled with red is, turned on the side so it is not a new part. By the way, IMO this is really an epic set, and I can't wait to get my hands on it.

TechnicBRICKs said...


Check carefully all the details, you will see it can't be! ;)

Povratnik said...

Sorry for my persistence, but I'm pretty ( 99% :) ) sure that the part is indeed 64179, and there's one on each side of the chassis. Or am I wrong?

TechnicBRICKs said...


Yes, I'm 100% sure you're wrong!
The orientation you have indicated and the part surface and hollows details shown in the picture, do not fit with the part details you're considering.

Look carefully! ;)

Jetro said...

It may actually be its big brother 64178

Povratnik said...


Sorry! My bad! I pictured it in my head, and I didn't turn the hollow part to the side. You are right.
On the other hand, the hollownes could be a shadow. Could it?

TechnicBRICKs said...


No it can't either!
There is no position where it fits completely with the image. :)

TechnicBRICKs said...


They can't be shadows in my opinion! ;)

Povratnik said...

Well, we will know soon. :)
Kind regards.

Mark said...

@junkstyle gio -
where did you preorder the unimog ? Ive requested information several times from my usual spot but i get no reply :( last years excavator was sold out while i was on holiday, so i want to avoid that this year

carzzzz9999 said...

i cant wait to get it, two details in two days its almost like Christmas, lol

hope that more details will be coming out shortly!

Menno Gorter said...

I was hoping a while there would come a c-shaped liftarm like the end of the 64178 5x11 frame.
It seems it still isn't the case; the one Conchas discovered has a different configuration from the one I desire.

Daniel said...

Does anyone know why the part 64179 has a small gap above each hole on 4 of its 8 inside edges? The part circled in red has this type of gap above each hole, including the hole on the end.

The new part could be a redesigned 64179, but I doubt it because 64178 is visible in the other photo and it has not been redesigned.

carzzzz9999 said...

One of the things I really love about this set, is the 5-color combination, yellow, orange, red,blue, stone gray and black. I think this color combination makes this model special and( maybe like the real thing)

Junkstyle Gio said...

@ Mark:

TechnicBRICKs said...

@Menno Gorter

Does it make a significant difference for you?
As far as we can see and imagine, the difference could be that we don't get two consecutive positions with holes in the same direction at the 'C' tips (like in the 5x11 frame), but with orthogonal orientations instead. IMO it should even add versatility to the utilization possibilities of such part.


This has to do with the production process and part extraction from the molding.
The mold has several parts and this is necessary to take them apart, after the ABS injection.
It is quite funny and interesting to understand the molding principles, to realize why certain details are seen at some parts. :)
The 5x11 frame is even more interesting regarding the same details.

TechnicBRICKs said...

Note also it is the presence of such characteristic on the portion visible from this hypothetical part, on the image now released, that made me conclude it might be a new kind of frame.
It is because of other characteristics from what is seen and the fact that it doesn't match with any of the existing frames, that I guess this could be a new C-shaped frame.

Menno Gorter said...

@ Conchas; I'm still in search for the strongest possible way to make a 90 degree angle with two 12t double bevel gears.
Of course I know there are a lot of possibilities to do with the half ones, only they are not strong enough and can't be combined with 24t gears directly after.
Even when I fill the present frames with an extra 3L beam it's to weak and not possible to combine with the 24t gears.
C-shaped frames like in the 8110 picture would come close, except for the orthogonal second holes. ;-)

Note: I need lightweight and compact constructions for my walkers....

Mark said...

@ Junkstyle gio

Thanks dude ! just pre-ordered my set.
counting down the days until it arrives :D

Alex said...

The suspension sucks. This model has a lot of negative caster. To see what i mean: . I am very dissapointed. But i will correct that once i get my hands on one of these.

TechnicBRICKs said...

@Menno Gorter

In that case you're right!
I'd imagine a spacing 3L beam would solve your problem, but if not, then I guess a spacing bush won't solve it either.
Maybe one dummy spacing 12t or even 24t gear, would address your use case!?

Allanp said...

@ Menno Gorter

Have you considered using these studded parts?

louis0304 said...

Are those pins in the wheels grey???Maybe another indicator for new parts to create a portal axle...

Wiseman_2 said...

If you look in the area between the blue ring and the red ring on the last photo, in the place behind the C-Beam, there is a part that I don't recall seeing before. Another new part?

It also suggests there is definitely a C-Beam in front of it, as it does not extend further back into the model.

TechnicBRICKs said...


I'm not figuring out, what do you mean with blue/red ring.

Wiseman_2 said...

I mean the rings you drew on to the image yourself to highlight apparent new parts like the springs and the location of the pneumatic pump.

Here, highlighted in white:

TechnicBRICKs said...


Doesn't seem a new part to me.
As it is DBG and the Technic holes lay all in the same direction, I guess it is a regular beam or liftarm.

Wiseman_2 said...

Still a bit of confusion there - someone on EB found it too:

Allanp said...

To sum up the speculation on eurobricks, the part behind the c-beam apears to be a large light bley ball that fits into a larger dark bley socket, allowing the axle the pivot up/down (for suspention) but also left and right, however there appears also a padhard bar (the angled 6L steering link) to prevent that happening, just like a real live axle. So if that is true, and that it is also prevented from rotaing along the axis of the vehicle, then we have another new piece(s) in the form of a torque tube. This is all speculation but if it's true then this thing is just getting better and better.

There is also talk of the pump. There appears to be a white logo on it. No idea why, probably signifies a prototype for another new part, maybe a longer pump as others have speculated. It's hard to tell, it does look a tiny bit longer, but it could be an illusion caused by it being partially covered by a beam in the picture.

TechnicBRICKs said...

Yes, it seems we are seeing there a kind of large ball joint. However at the moment the questions are just more than the answers.

My first conclusion is that probably the ball joint has nothing to do with the new gearbox hubs for the portal axles. Also from the place we're seeing it, which is quite far away from the wheel axles...
It looks pretty close to the center of the vehicle and to the battery box.
Being this also a 4WD vehicle it looks to be almost in the place of the central diff. Maybe it is just behind it!?...
For the pivot function, I believe there is a regular 3L U-joint running inside.

As for the pneumatic pump I still find a bit strange the relative positioning to the motor.
But guess the red driving ring on the top of the motor explains it all and tells us where is the pump shaft.
Despite a new intermediate pump size would be welcome, I still doubt it is the case. Still believe this can be the existing small size, which is partially hidden behind a Technic beam.
Have no idea what is the white mark on the pump though.

Mark Bellis said...

Stump: The gearbox functions seem to work like this: The left (yellow) lever switches between the air compressor and the front and rear PTO drives (winch and turntable). The right (red) lever switches between the winch and turntable when the yellow lever is in the winch/turntable position.
The rear view shows a worm drive to the white clutch gear for the turntable. The mechanism for tipping the body remains a mystery for now.

I had hoped they might have brought out a part that I made in 2007 but sadly not because the grey parts at the base of the turntable are the regular double ones. I would call this part the "minim" after the double length musical note.

Might have been nice to see more rigid 3.2mm tubing and less flexible tubing that is prone to the balloon effect, especially for precise control of the small grab cylinder. Use of the rigid tubing with half pins in existing toggle joints would have made the new nozzle pieces unnecessary. Good to see the small cylinder back though.

Rail wheels that could be lowered is another possible application for the pneumatic parts, once you've built the rear crane and the front snowplough.


Allanp said...

There is still a need for the blue element as the rigid tube would move inside the half pins long before the hoses go on or off, but yeah, it would have been nice to have rigid tubing in the crane arm for the long straight bits.

Unknown said... Anyone seen this? Perhaps you're already about to blog it? :)

TechnicBRICKs said...


yes, I've seen it. Thanks!
Post to be written after work only. Unfortunately. ;)

Unknown said...

And there's more:

...but I guess you do follow these things so I'll stfu. :)

Ian said...

Has anyone seen THIS?!? Trial Truck Bliss! new parts new parts woohoo!

carzzzz9999 said...


Thanks for the links

Miguel said...



Djamil said...

Another NEW part. If you look closely at the bottom picture, circled in yellow. The 4L 'axle with stop' goes through 2 L-shaped lift-arms that are only half-thickness. These lift arms are NEW. The seem to be a thiner version of 32410 (, with cross holes only (not round).

Jetro said...

I see two of these ;):

And the complete inventory is available here:

Djamil said...

That's a good point. These came with the new TLB (backhoe) ... good catch.

Ian said...

The full instruction available on US site, you can see all the new parts here in the 5(!) books of the set!
