It’s an offset oval so can turn 360° And cycle back and forth

I figure 2 of these offset by 90 give same action as Porsche gearbox

 Anyway, looking at the gear selector, how would it be used?  To me it looks kinda like a worm gear

It's very similar to a worm gear, except the "thread" is a closed loop that has one low, one high and two medium points. When a low or high points is engaged with the gear shifter ring, one of the two red gears is driven. When the medium points are in contact with the shifter ring, neither red output gear is driven. 

The beauty of this selector is that it can be driven continuously in one direction, and will just cycle between all the states. It can also drive two gear shifter rings at the same time, allowing 4 gears with a single rotation of one shaft.

As an added bonus, the output of the gear selector shaft can be linked to a secondary mechanism (gear indicator dial, spoiler with adjustable height, adjustable suspension, or even another gearbox).

This new orange ring replaces red gear selector levers and lowers number of parts required to build a gearbox.

That makes sense, thanks for the explanation.  

So that means a 90-degree stepper would get you from 1st gear to 3rd and a downshift to 1st.  I hope the exhaust sounds good at the price you guys are paying for this set

Actually the hope is that it doesn't make "gearbox dying" sounds like Posche did, not the exhaust xD

Well, let's talk a little about the front axle, as you can see it will have a suspension, but what kind of parts are at the top and bottom of the hub, what kind of suspension arm is that? 57515 or 15459.

Any idea on how those selector rings will be controlled? If each one is connected with two clutches there won't be a neutral position in each "sub-gearbox", so it can't be a simple layout with one clutch-position corresponding to one of the (probably) 8 gears. That means, that the orange selector rings won't move at the same time but are controlled by a mechanism that transfers the 8 positions of the gear lever/paddles to two independent 4 step rotations.

In the first seconds of this video you see a black knob wheel and next to it an orange (0x)-piece with a pin-with-tow-ball inserted. I suppose the knobwheel will control the 4-speed gearbox for every shift and the towball will control the 2-speed gearbox every 4 shifts.

EDIT: I'm still not sure how the gearbox works. Theoratically, it could run through 16 different positions with 2 selectors each controlling 2 driving rings.

This is the most likely scenario. This means 8 speads instead of 7+R.

What's really interesting is paddle shifters or any other mechanism that will change gears. There must be significant progress after Porshe, or maybe only slightly improved version. Axle connected to that mechanism is located right on the center of the car.

If they use my shifter it will make me immortal .

That's plausible, but there has to be at least some difference. I'm sure they investigate MOCs to not repeat them. New pieces only support this idea, they basically revolutionize approach to gearboxes with this set.

But... how is it even possible to put those orange pieces in other sets in the future? I guess we won't see them again until 2020 or so. Let's hope that we'll have new blue gears in 2019 sets, I need a lot of them, or at least 3

The wheel hub have ball on top, i think will have suspension, but what kind of suspension will have?

You're not far off  

[Bublehead]

Right now, asking “have you seen it?” Is like asking why is there air?

Of course it will have suspension, of course it will be independent. Most probably it will have two shock absorbers on each side, because of wight.

Maybe it's time to lock this topic again? (for 4 days)

What I noticed, there will be at least 2 books (instructions) for this set.

Holy Belly-Flop-In-A-Pizza! That's going to take me days to build this!

I'm expecting this to come with a unique serial number printed on a 1x4 tile!

And I saw someone of the Czech Republic get his hands on one! https://www.facebook.com/photo.php?fbid=1625461590855206&set=pcb.2115721365166552&type=3&theater

I've been playing a little with how to take advantage of the new parts. I tried making a compact sequential 4-speed gearbox layout and so far this is the most simple solution I could come up with. It's still not that easy because to take full advantage of the new orange selector, the driving rings cannot be placed on opposite sides of the gear selector.

To take full advantage of the new 20t clutch gears, the gear ratio between the two driving rings needs to be closer to 1:1 than the 20:12 ratio made by the new clutch gears. In this case I used 16:20. Ratios are: 4:5, 1:1, 4:3, 5:3.

• Green is input
• Yellow is control
• Red is output

More box  photos leaking now. The side view is indeed much better than from the front.

Cnfirmed brake calipers front and rear.

[Jaromir]

woow, when I am looking at recent photos, I have to admit that I have started to like the way it looks, even though I didn't like it at very beginnig. However, when I am lookingg at body line of Chiron on the side view picture, I am not sure if it close to real Chiron.

What software do you use?

[SheldonF]

Side view is pretty close, I did a comparison on my own to see and it isn't far off. I love the lines of this car. I need the next 4 days to fly by. 

[StudRobotics]

Where can I find some more leaks?

You only need to use a little imagination  . For example, you could make a four output distribution gearbox operated by turning a single Bionicle tooth, which would look smoother than a classic lever solution and be simpler and more compact than one using the Porsche mechanism.
