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!
