Yes, a more spacious trunk would have been nice indeed. That is exactly my reasoning at the time as well when dealing with this part of the design, and your conclusions match the ones I had at the time. Those who don’t care about a gearbox can always easily remove it. The conversion the other way around is much harder. There are no parts specifically designed for this car. In fact the first prototype of the car also had to undergo a conversion, switching to CaDa’s adjusted panel system. The final car uses some parts exclusive to CaDa but a conversion back to Lego is always possible with a bit of puzzling and creativity. Thank you for sharing your thoughts @kbalage! I agree with your perspective, and this is also exactly the direction in which we are trying to go. CaDa has been moving forward in this regard, but this model has been finished for about 2.5 years now. That is also why the model is not equipped with the most recent parts in the catalogue. The mindset was different back then, and even more at the start of the project more than 4 years ago. Meanwhile, especially @efferman and @brunojj1 have contributed greatly to designing new parts: a new concave panel system, shock absorbers that can be adjusted in stiffness, custom gears, and a bunch of more versatile connector pieces. CaDa's R&D team themselves also try to expand their custom pieces inventory, if you take a closer look at their most recent releases. Ultimately, we don’t want to create too many single purpose parts either, and the overall system formula is successful as it is. The next releases should unveil more of these parts.

Here we go finally, may I introduce my rendition of the famous Audi RS6 . Appologies beforehand for only showing renders at this stage. The model is currently also on display at the Shenzhen Toy fair, built with real bricks, so hopefully the people present there can share more. Though an official release date of the set is not confirmed right now, sales are expected to start this summer. The project started in early 2022 in agreement with CaDa and supported by Audi as an official licencing partner. It took roughly 18 months to complete the main design, with plenty of ‘creative’ breaks in between. The design objective being finding a good balance between the chassis (functionality) and bodywork (appearance). Furthermore I increased my efforts to improve the building experience, making it a bit more accessible and less punishing. But don’t worry, you can still expect a nice challenge! Features: - All wheel drive (Quattro) with three differentials - V8 engine + rotating cooling fans - Steering with HOG - Independent suspension - Adjustable ride height - 8 Speed sequential gearbox, operated from the trunk - Adjustable front seats - Openable doors, trunk and spring loaded hood As is usual with my builds, I refrain from ‘recycling’ of existing mechanisms and always try to be innovative wherever I can. Doesn’t mean I’m always trying to reinvent the wheel, but just trying to be creative and finding unique solutions that make the build more interesting and overall appealing. That being said, replicating the RS6 posed many interesting challenges along the way. Firstly, its mechanical platform is very different compared to typical supercars. The engine is located in the front and the interior occupies much more volume, leaving much less space around the rear axle to integrate mechanisms. Secondly, the bodywork does not have as many extreme shapes – it looks more like a ‘normal’ car. Meaning it’s even more important to follow the more subtle lines and shapes in order for the model to be recognizable, which at times can be just as challenging as replicating more exotic bodywork. Gearbox: As pointed out already, wrapping a gearbox around the rear axle requires a unique layout. I opted for a rather flat and long lay out of the gearbox, which stretches from below the rear seats all the way to the back of the car. 8 speeds are obtained in the conventional way, by combining a 4 speed and 2 speed gearbox. However the shifting scheme is very different. The 4 speed gearbox with its integrated centre differential has very large gear ratio gaps, so instead of scaling these ratios going from gear 4 to 5, the 2 speed gearbox is used to fill these ratio gaps. Consequently, the 2 speed gearbox shifts during every gearshift, whilst the 4 speed gearbox shifts every second gearshift. The shifter is located on top of the whole structure, making it very accessible and easy operate through the trunk. As Always, I am looking forward to reading your feedback and to further discussions about the model. Thanks, and have great day!

My next entry in the CaDa Master series will soon be unveiled at the Shenzhen Toy Fair: A licenced 1:8 scale replica of the legendary Audi RS6. Stay Tuned!

It is definitely possible, as the original design was made with official lego parts, see my original post. Afterwards many people have succeeded in building it with original parts as well. It should be fairly straight forward, because the CaDa set was essentially retrofitted with their panel versions.

Just to confirm and avoid any misinformation, the Audi RS6 is my next design for the CaDa Master series. Unfortunately I cannot share more information about it at this stage and I was surpised to see this seemingly leaked image. The licencing has caused many delays, as with Bruno's AMG ONE back in the day, but hopefully I can share more details about the set later this year. Could very well be possible, emphasizing the 'eventually' though.

@Tup4n Thank you for sharing the final work! The result is impressive, to say the least, and I am glad you could keep some of the original features. Not to mention the looks have not been affected much, as well as the interior - bravo! I hope the dynamic suspsension assists in stablizing the car through turns. In fact that was the main idea behind the mechanism, although I never imagined someone driving it around at speeds where it could ever make a difference. Cheers!

@Tup4n Wow, awesome work man! Keep me posted for the final result. Did you manage to keep the dynamic suspension? Its hard too see on the footage

@Tup4n Thank you for sharing! I am curous to see how it will end up perfoming, keep me updated!

It is neither Bruno's creation, nor mine. My upcoming model will be from a different German Brand. It is designed by a young Chinese guy working at CaDa. Bruno and I had the opportunity to see it in person during our trip to Shenzhen last year and it is really something to look forward too!

I wouldn't worry too much about the catalogue. The are some other bigger releases lined up for 2025, including my next entry in the Master series. Absolutely! To give a bit more context: a brand new line up of concave panels has been developed. Sizes and profiles are similar to the ones in the convex panel set we've known for many years. In fact, many are concave counterparts to the original panels, e.g. the large panels resembling the front wing elemens on the new Sauber are the concave version of Lego's #5/6 panels. One can also spot a 2x2 transistion panel next to the headrest which can line up with both the convex and concave panels and is super versatile IMO. It will allow even better bodywork replication, particularly in exotic cars where convex surfaces appear frequently. Not all concave panels that have been developed so far appear in this set, but it should give a good idea about the system.

@Tup4n Sounds cool! Surely you will have to redesign huge parts of the chassis and some parts of the bodywork. - Yes the weight is arround 3KGs, I am unable to give you an exact measurement at the moment. Parts count doesn't always scale proportionally with weight. I used quite a lot of small parts and don't forget that CaDa's panels and frames are composed of several sub-parts. - Yes, you can use Sian or bugatti rims Make sure to share the video here once the projected is completed!

Very nice model and presentation, thank you for sharing! Creative approach to the concave door and I like how you used the wrench for the taillights. I think it would look better in yellow though

Great build Lox! I like the new direction in which your latest builds are going. I see greater panel density whilst ommiting the usage of small liftarms and connectors to replicate shapes. I must agree with the critics of some others here regarding the doors. I personally would have kept the door itself rectangular / 'legal', and rather inclined the whole door with respect to the chassis. This does impose a new challenge on the door hinge, but there are many ways to deal with that.

Correct. I see no logic/patern in why some parts have active patents and some haven't. The vast majority of the parts is not protected. As far as I'm aware of, in the technic catagory only a list of panels, some frames, rotary catch and these parts: , , , , , . Yes, that is the plan.

Thanks for the heads up Differences compared to the previous version: 1: Replacement of old curved panels by the new ones to comply with TLG's copyright. (notice the rounder panel edges on types #1/2, #3/4, #5/6, #13/14, #17/18, #21/22) 2: Replacement of several other pieces to comply with TLG's copyright, most notably: , 3: Minor structural improvements, only in areas where where it could be realised with minimal changes/extra parts. E.g. the rear pinhole in the mudguard panel is now connected to the subframe of the engine cover and the taillights are much better secured now. 4: Potentially improved parts quality. I cannot confirm this, but improving part quality is a continuous on-going process, not specifically for this set of course. Now that the CaDa's parts catalogue is fully compliant with TLG's copyright, us designers can safely work with all parts in their current catalogue (and help innovate new parts!) without unwanted surprises like was the case during development of this set. Hence, the quality of the sets will only continue to go up, exciting stuff to come!

@BrickMonkeyMOCs Thank you very much for sharing your thoughts and modifications - It is greatly appreciated! I fully agree with you and, of course, I am well aware of the mentioned flaws. I do want to elaborate on the sagging engine cover: In many cases, this occurs because of incorrect orientation of the tri-connector as illustrated here: I do recommend trying to re-establish the encircled connection below, which the R&D department removed. The red pin connector would clash with their new panels, which don't have the half-stud gap below the #13/14 panel. This will add some needed rigidity in the engine cover. A fix for this is included in my V3 as well, but I currently cannot provide a better illustration unfortunately.

@head1004 The model was designed with the older shocks, because the new ones were not in production yet during the design phase. Moreover they are much harder to integrate properly due to their size, particularly in a model like this with complex suspension features. I haven't seen any mods yet with updated shock absorbers and will personally not invest anymore time on this finished project. @amorti You are aware the car in the link you sent is a totally different build of mine, in much smaller scale?

Sorrry, but I don't have any updates on this at the moment. Considering the large amount of sets which are about to be released, I can imagine the release of the updated version will not be prioritised. I'd say keep an eye out on the CaDa webstore. Logically, the box design will be updated for the v3 because the updated panels - that is how you can identify which version is being sold. I would advise you to consider getting the V2. There are plenty of forums/videos with people illustrating adjustments you can make. Besides, most of the updates are to avoid usage of copyrighted parts. In the meantime I am investing all my free time in my next big licenced release.

Background story: the making of the 1:8 LaFerrari After having to create some room on my phone's memory card, I came across all of the WIP pictures of this project again and thought, why not share these with a little background story. I always found it interesting to read WIP journies myself so allow me to present a brief summary of the making of the 1:8 LaFerrari: ~April 2020 Starting with the first technical challenge of this build: Rotating paddle shifters. I experimented with countless of steppers and their placements in the chassis. Most steppers suffered reliability issues due to the amount of torque on the output required to shift the gearbox. The closer the stepper is to the paddles, the better. The final solution uses the standard Didumos69 stepper which works very reliably. Unfortunately I couldn't manage to make the paddle shifters return to center automatically, which admittedly is one of the big defeats of this project. ~June 2020 Moving on to the dynamic suspension with integrated nose lift feature. Getting these features to work perfeclty in parallel together was a tremendous challenge. Dynamic suspension requires the shock absorber mounts to rotate in the same direction wheras the nose lift feature requires those mounts to move in opposite direction. My first solution was interesting but didn't work well in practice: too much play in the mechanism, resulting no rolling movement and/or too much friction when steering the car,. The steering is linked to the red 16t clutch gear wheras the nose lift was opperated through the worm gear meshed in the differential. ~August 2020 Starting on the monocoque, trying to clear my mind from the front axle. ~September 2020 It took 3 months of prototyping before I came up with the break trough idea, detailed in the OP. An early prototype is shown below here. ~Oktober 2020 The first version of the chassis finished, including the seats and other interior details. ~February 2021 A first prototype including full bodywork was finished after a couple of months of body sculpting. Especially the front fenders and engine covers provided me with enough frustration to punch a hole in my desk. The final soltution for the front fenders is a questionable approach, but couldn't find a better way to do it without exceeding the proportions too much. Some don't care as much about that, and rather put mudguard panels on - a matter of preference. The engine cover is a delicate task not only because of the shape, but also because it has to remain a compact shell, being able to open and close to reveal the engine bay. ~April 2021 The first prototype did not really satisfy me, many body proporions seemed off. I finally realised that the blueprints I used were incorrect. After recalculating the proportions, it was time to work on a second version, also taking advantage of the new panels released in the 488 GTB set. Starting with a redesign of the nose, I soon realised I was heading in the right direction. The pictures below show some different and ultimately unsuccesful front fender ideas. ~July 2021 Reworking the rear and a new engine cover design. I discarded my previous rear wing designs which, despite idential kinematics compared to the real car, ended up compromising the surrounding bodywork too much. ~Oktober 2021 Finished the new front, rear and engine cover. The doors were also updated, and I opted to increase the wheelbase by a stud. ~January 2022 After some small chassis upgrades and refining some building techniques, a handful of new parts were released and I didn't hesitate to use them in the final prototype. The tapered panels allowed me to improve the engine cover and front wheelarches whereas a few 1x2 panels fitted nicely on the nose. Despite all efforts I guess it's fair to say that the final car was compromised a bit by some silly mistakes and architectual choices I made at the beginning. For example, I think the car would have looked better on a narrower (29 studs) chassis compared to the final 31 stud chassis which my initial blueprint indicated. At some points in these projects, you reach a point of no return, where the cost of redesign becomes too much to be considered worthwhile. You always come up with new ideas, even if the car has been finished for months, but there has to be a point where you have to pull the plug and decide you are satisfied. After nearly two years enough was enough, and I rather took all learned lessons with me a to a new, fresh project. You can browse the full gallery with plenty of photos here: https://www.bricksafe.com/pages/T_Antonie/the-making-of-laferrari-moc-18-wip-photos# I hope you enjoyed the read!

@billquan I'm sorry but no. It was mod from Pvdb's one:1 which does have building instructions. Please send me a PM next time for such questions

I'm not sure. Either way I will post an update in this thread.

@BrickMonkeyMOCs Thank you! Production of the V3 is scheduled to start in December. The V3 will include all my proposed fixes and I recommend buying directly from the official CaDa store to guarentee ordering the newest version. No need for Lego wave selectors - CaDa's solution works equally well. My original dashboard design requires very specific bionicle pieces which were not versatile enough for them to add two new molds, that is why the CaDa set uses a different gauge cluster. Feel free to swap using your own inventory.

To add further, here it is shown that you can flip the quarter ellipse, if that is more favourable for the mounting the panel at a particular angle. The three axle holes are also a nice advantage. Originally, I wasn't enthusiastic about these panel changes, but I am starting to appreciate them more and more. IMO the main downside is the updated fairing shape (curved instead of straight edges) which tends to leave more gaps in the bodywork for a large range of panel compositions - at least that is what I concluded after applying them to the exterior of my new MOC.

Let's just wait for the designer himself to present the model and to hear more about the background story of this unique build. I am excited for it from what I have seen but won't jump to conclusions too soon. I bet there is a lot to learn and to discover regarding the innovative approaches/techniques. Servo steering is always tricky for AWD cars due to the CV joints constraint. Gearing it down will generally off-center the gears, which means adding more gears to recenter, resulting in increased slack and reduced straight line stability. You could introduce positive caster but I don't know how much it would affect the performance in practice.

Thank you guys for showing your results! @LegoHoops I recommend to recheck the instructions for the engine cover. It looks like it's pushed up, hence it doesn't sit flush. I think you have flipped the 1x6 liftarms upside down. Fixing it should make the engine cover closing smooth as well.
