It does not.. you need the new cog gear

I was looking for a new project and stumbled upon Lamborghini's Egoista. This had interesting shapes but most importantly only a single seat and no doors: I dislike trying to make a sturdy vehicle with two seats and doors; it is difficult work for mere aesthetic benefits. I knew I wasn't going to be able to accurately represent the steering column, front/bumper area, or the colors so consider this MOC "inspired" by the Egoista rather than a replica. Design goals: Concept car with unique angles and shapes, similar to the Egoista. I mostly succeeded here. The sides are probably the most boring but still have some interesting lines. I like the way the shocks are slightly visible, and the view of the engine through the side. Bodily strength. No "sag" or "warp". I mostly succeeded here. I can pick it up from the middle or the ends with minimal sag. Lateral warp is minimal, if any. Minimal "backlash". Keep gears to a minimum. I succeeded. Single gear to the steering rack. Transmission directly connected to the differential. The most "slack" is between the transmission and the fake engine where there are two "extra" gears. Do something "different" with the transmission. I mostly succeeded. At first I wanted to do a 6 or 7 speed transmission with a neutral gear using the "new" transmission pieces from the Yamaha motorcycle and McClaren 1:8. I also wanted to keep the transmission "flat", which meant using different techniques than the official McClaren set. In retrospect I could have built it more vertically and pushed the fake engine back. With a "flat" transmission I found realistic gear ratios surprisingly difficult to achieve. It turns out https://rebrickable.com/mocs/MOC-171508/Anto/ultimate-6nr-gearbox-with-forks/#details may be about as good as it gets, but I didn't like the inconsistent ratios between gears. In the end I used an approach similar to https://rebrickable.com/mocs/MOC-201002/paave/realistic-4-speed-sequential-gearbox/#comments and used only four gears. I had intended to have a "neutral" gear as well, but I mistakenly thought the Yamaha drum had "notches" at the 1/4 mark. Instead they are 3/8 apart, which makes 4 sequential gears + neutral impossible when the gears are on a single axle. So what could I do that was "different"? I decided to add a motor...but one that is by default decoupled from the transmission. This allows the car to be pushed across the floor with fully working gear shifts. I can then put it on a pedestal and turn on the motor to demonstrate how the wheels spin at different speeds with different gears. I also geared up to a shifter directly rather than using a ratchet or traditional "manual" gear shifter. I either directly use this shifter to move through the gears or, for ease since its hard to get fingers into the cabin, there is also an external knob that can shift the gears. On to the pictures! Not sure how to embed Google Photos (insert image from url failed), but these links "should" work.

Two videos:

The actual bike has 6 speed...would have been more interesting if this had more gears.

According to Unbrickme's video, the ratios are 0.71 1.1 1.77 2.76 4.42 6.9 11.05 The actual P1's ratios seem to be closer to linear: 0.71 1.081710677 1.483732283 1.911095335 2.434547804 3.119768212 4.120276968

I'm liking what I'm seeing so far. Novel, simpler, and hopefully more consistent gearbox and paddle shifters. Rigid body. Proper wishbones. No weak pieces (such as 11478) being used under stress or weight. Even interesting exterior functions with the doors and spoiler.

In my MOCs with 5L steering and 7L arms I've never seen it be an issue. It was an obvious issue with 8880 but it had much larger angles between the rack and wheel.

I've been assuming (perhaps incorrectly) that https://www.bricklink.com/v2/catalog/catalogitem.page?id=235271&idColor=86&ccName=6469530#T=S&C=86&O={"color":86,"iconly":0} will be a major player in the next Lego gearbox. Which would imply two axles of cylinders still, but may explain the 45 degree offset.

"We must have female representation no matter how ahistorical such representation is" "We must have no islander representation lest we be the least bit ahistorical" I don't really care either way about the gender of lego characters. I would like to see some Islander sets, though at the moment I'm just grateful there are more pirate themed sets. Probably won't pick this one up though. It feels too "blocky". An homage should embody the spirit of the original but not inherit its limitations.

I wonder if https://brickset.com/parts/6279026/cross-block-form-2x2x2 could be used instead of https://brickset.com/parts/6261375/cross-block-90° to connect the wheels. I use that technique for MOCs from the Bugatti and its very robust.

I'm tempted to buy this, I skipped the Sian but have the Bughatti..this is distinct enough that I could justify the purchase. But I'm still concerned about the stability of the suspension and wheel connections. Has anyone built this and can comment on whether the approach is robust?

Are the wheels really only attached to the arms by a 40146? That seems like it will break in no time...

Any updates? I'm particularly curious about the narrow gearbox!

Not sure where to put this in its own topic or not, but since it is mostly Nico's work I'll put it here :). After building the Bugatti alternative I wanted to improve two things: the steering radius and the weight distribution. I had managed to improve the steering radius in the original design, but had sacrificed sturdiness. The front-heaviness of the vehicle caused the front suspension to be a little mushy and the back suspension to be a little too firm; and made "driving" the vehicle difficult. I thus decided to try to create a race truck similar to this: Freightliner I also didn't limit myself only to the Bugatti pieces, though the vast majority of the pieces are from the Bugatti. Here is the result: https://photos.app.goo.gl/N37VqtCcx8Yf8ePK9

Just read up on the race truck. I really like: The model itself...its a good choice since it allows for a consistent "thickness" to improve stability. My struggles with 8:1 models is that they are very difficult to make sufficiently sturdy since there is typically only a thin center console to support the length of the model. The ability to see the full transmission The design is gorgeous Couple questions: Does it have Ackerman steering? (I'm guessing not since you didn't call it out :)). The video seems to show minimal steering angle; is this correct or just how it looked in the video? Since its not a 4wd I was hoping for a better steering angle. Since you only use 2 shocks in the back did you consider using 3 each on the front to address the sagging when the cabin is open? Regardless I'll probably purchase the instructions. Since I have a lot of extra (non Bugatti) parts lying around I'll likely mod it to see if I can add 4wd and Ackerman.

This is an excellent MOC and probably as good as it can get using only Bugatti pieces. After having it built for a few months I started to wonder if I could improve on it from my collection of lego I had on hand. My goals were 4WD At least 4 gears+N Widen to be the same width as Bugatti (this actually is more accurate to the R8's actual dimensions) I (mostly) succeeded. I stole ideas from many people to make this happen; almost none of the functions are my own. Despite having more pieces I wasn't able to quite achieve the looks of the original R8. My gearbox was too wide and the engine too far forward. Still, I'm fairly satisfied with the result given that this is my first large scale MOC.
