i know you mentioned in the discord that it was at the line where it might look like a proto, but im submitting it just to see what i can improve in the design (btw rtx lighting fucks this car up)

It could do with some more sculpting in places, but as far as I know, it would make for a good starting point as things stand right now.
exterior is pretty much done apart from some smoothing i need to do

I canât speak on behalf of the hosts, but you may need to do something more with the sides. They donât seem aggressive enough, especially where venting air from the front wheel wells is concerned.

yea, the side needed some more work ngl, bit too tame rn

2020 Hana Ćdachi
360kmhăè¶
ăăæăæé«ăźćèĄĄăă
(Achieve perfect balance at +360 km/h.)
| Named after the longest type of samurai sword, the Hana Ćdachi is the newest flagship car for the Saitama-based luxury brand. One of Japan's first hypercars, the Ćdachi is unique for adopting a front-engined layout for balanced weight distribution. |  |
ĆDACHI GT
 |
 |
The 2020 Ćdachi GT is the road-going variant, complete with an all-wheel-drive, 8-speed dual clutch transmission. Development of the plug-in hybrid began in 2015, originally based on the mid-engined Hana Kaze concept car from 2002. In order to take advantage of a 50:50 weight distribution, the Ćdachi became a front-engined project.
To aid cornering, the GT has four aerodynamic plates, one atop each fender, which dynamically tilts according to steering and braking. The plates activate at low and medium speeds, before closing above 300 km/h to minimize drag.
Through its two parallel LED headlights, running horizontally across the front fascia, the Ćdachi's unique Hana design identity was retained. However, Japanese culture also played an important role in the philosophy of the Ćdachi's design. Designers of the Ćdachi took inspiration from Japanese Group C prototypes, including the Mazda 787B and Nissan R90C. As for the interior, the lead director in design found peculiar inspiration in anime, mainly mecha-- fictional battle robots controlled by humans. The idea was to make the driver feel as though in control of precise, powerful machinery. That is true in one way or another.
ĆDACHI LMH
 |
 |
The Ćdachi LMH is the ultimate racing version of the hypercar, made to compete in the Hypercar category of the 24 Hours of Le Mans. With less restrictions, the DT8 engine was retained with stronger turbochargers, achieving a maximum output of 804.6hp. However, in order to conform to restrictions related to aerodynamics, the active aero plates were removed, leaving holes in the fenders that expose the wheels to naked air.
Several measures were also taken to reduce weight as much as possible, such as stripping the interiorâs luxuries as seen in the GT. The display above the steering wheel was completely removed, and the digital interface between the seats was replaced with carbon fiber racing controls.

nice job, i like the side vents 
Barbecue at the Paddock: Round 2
IRL stuff are ramping up for us, which is why it took us this long to make this post. We'll try our best to get to every car before the actual deadline, though keep in mind that there are a lot of cars queued for review.
In case you forgot, these posts are for feedback before the actual deadline, instead of the actual judging.
In the meantime, here's an example of GREAT racecar engineering
and of course the event organizer is constantly innovating the rulesets, because of course they do
/
Before we get to the cars, we thought we might do a little crash course on Le Mans classes, for the folks that aren't quite up to speed about it:
-
LMP1 (Le Mans Prototype 1) was the top sports prototype class of the World Endurance Championship until the end of 2020. This included cars like the Porsche 919 and the Audi R18. LMP1s are NOT what this challenge is looking for.
-
LMDh (Le Mans Daytona hybrid) is a sports prototype class in the WEC that races alongside LMH cars (similar names, but different classes; donât get confused). This includes cars like the Porsche 963, BMW M Hybrid V8, and Acura ARX-06. These are sports prototypes, much like LMP1s, and are therefore NOT what this challenge is looking for.
-
LMH (Le Mans Hypercar) is the new top class of the WEC, replacing LMP1. This includes cars like the Toyota GR010, Peugeot 9X8, Glickenhaus SCG 007, and Ferrari 499P. Although the name includes âhypercarâ and there is an option for manufacturers to build LMHs based on road-going models, the current crop of LMHs are not related to road-going cars and are sports prototypes, much like LMP1s, and so the current crop of real-life LMHs are NOT what this challenge is looking for.
So exactly what is this challenge looking for? This challenge imagines a scenario where manufacturers were forced to make LMHs based on road-going cars, not sports prototypes. One real life example is the De Tomaso P900 LM, based off the De Tomaso P72. Therefore, we are looking for a high-performance road car that can be termed a Hypercar, like the P72, AM Valkyrie, and McLaren Senna. In addition, a racing variant of the road car is required. This race car will have to conform to the regulations sheet provided. For more examples on the sort of car this challenge is looking for, see the inspirations chart in the challenge post.
The original challenge post was created under the assumption that most people has at least some form of motorsports knowledge, but upon talking to the participants in this challenge, that is obviously not the case.
There are also some concerns about our performance requirements restricting the styling freedom. Because we mentioned the Aston Martin Valkyrie AMR Pro as a performance benchmark for the race car, some folks are getting the impression that you must make a Valkyrie lookalike to satisfy our requirements. As uniqueness plays a big part in this challenge, and weâd like to see a diverse field of cars, in fact, making a watered down Valkyrie lookalike is the quickest way to get you a zero in creativity.
So what should you make? For the road car, we donât necessarily require you to make the absolute most track focused road car ever, but it should at least be fast enough to match the holy trinity (P1, 918, LaFa) in track capability. This should open up a lot of opportunities in unique styling, but despite not having to look like a purpose-built track car, it should still look sufficiently capable. The race car on the other hand, does require you to give it a lot of aero so it can match our target performance. It should still be based on your road car obviously, and there are examples such as Sean Bullâs LM Hypercar renders or even cars like the De Tomaso P900 in how to adapt a wide range of body shapes into the level of race car we want. If you are allergic to wings and bargeboards and aero sculpted race car designs, thatâs also fine by us, as long as you enjoy your stay in the bin city.
With that out of the way, let's get to the cars.
SurrealCereal
WOOHOO HELL YEA BROTHER WEâLL DEFINITELY GIVE YOU SOME OF THAT FEEDB-
âŠoh
uhh
well,
the good thing is that the LaFerrari body should be a viable body for this challengeâŠ
âŠand I think thatâs where the pros end.
At first glance, we almost thought the car is made with Automation from the kee era or something - there are definitely better choices for those light fixtures for a modern hypercar. The overall construction also looks like it came from Automations 15 versions ago, with little to no modifications to the shape of the body at all, resulting in a look that looks like a LaFerrari body with things tacked onto it.
For the road car, you donât necessarily has to have the best aero ever, but for the race car, there must be little to no compromises in the aero department to achieve the level of performance we want. So did you do that?
This is the front aero on your road car:
and this is the front aero on your race car:
Yeah it doesnât really take a PhD in aerodynamics for you to realize that, that teeny tiny lip youâve added to the race car isnât really enough to balance out the race wing and diffuser youâve added
AlsoâŠ
jesus christ how deep are those wheels? And whatâs with those tiny, tacked on looking exhausts?
and what is this F1 tunnel fixture clipped through the body supposed to represent? We think you might be trying to make a race side skirt or something, but as it is, it looks like⊠an F1 tunnel fixture clipped through the body for some reason.
(There are many things left on this car where we can pick apart, but we think weâll stop here. As youâve mentioned, you are relatively inexperienced on this kind of cars, but unfortunately, on all aspects, this car as-is is not competitive at all among the cars weâve seen so far.)
sorry if we sounded too mean but yea this one needs some work

Riley
The front of the car is overall well crafted, although the splitter we think might be a tad too boxy given the context of the rest of the car, but not a big issue. Though we arenât sure what the dip on the windshield is supposed to be:
Overall design wise, this car is pretty good, but it feels like a supercar instead of a hypercar. Some of that feel can be attributed to the sides, which feels quite empty without any air intake. The side of the car also doesnât make a ton of sense aerodynamically, since a 800hp powertrain would require quite a bit of cooling. The height is mostly fine on the road car, but on the race car, we felt that it looks quite tall, and there are too much fat above the fenders. We think it could look a lot more lean and aggressive if you lower it a bit:
(notice the lack of bodywork fat above the wheels)
Aside from the height, we also think the aero for specifically the race car isnât quite on the level we want just yet. Aside from the aforementioned lowering and side intakes, we also would like to see big openings behind the front wheels, if you didnât realize how much we love that that from the previous post. The wing endplate also seem really boxy and squared off, resulting in the rear end looking like a flat board. Weâd like to see you give more creativity to that section of the car. Overall, we think you need to aim for a more aggressive aero design.
We see that you wrapped the tires with sponsor decals. We appreciate tire stickers, but how would beer sponsor stickers work on the tires? Do the team slap those stickers over the original tire brandings? Would the tire supplier allow that?
Some of the other complaints we have include the seemingly random chrome shapes on the livery that doesnât really add much to the design, the odd choice for race car light projector (take a look at real endurance race cars and their projectors), livery that feels very empty at the sideskirt section of the car, and the oddly tiny exhaust pipe on the road car.
Overall this is a solid entry, although it feels a bit too supercar than hypercar, especially on the race version.
the-chowi
While there are some efforts in making this not just another supercar, namely the sides with the openings. Overall though, this car doesnât exactly blow our pants off or anythingâŠand this also applies to many of the carâs weâve seen:
The supercar/hypercar rant (not just for this car)
Looking at this car, as well as many other entries we've seen, it's hard to imagine that it is supposed to be the exclusive top tier hypercar that we want. To be fair, it's hard to quantify the line between a regular mass-production supercar and a hyper exclusive hypercar in terms of aesthetics. Nonetheless, to use the McLaren family as an analogy on how your cars should look:This is good:
Something like this would be acceptable too:
If you want to go crazy, this but a road car (but more functional and less concepty, and the fact that it only seats one):
This however is too tame:
Again, you donât have to make something designed solely for the track like the Valkyrie, but many of the cars that weâve seen so far, especially the ones on supercar bodies like the McLaren, are just too plain jane for our prompt. Instead of changing the body and start over again, we recommend you people to try to do something special with it and change the body shape, like the Yurimacs car shown on the last post (though you donât have to make it full 3D like that, but you get the idea).
Going back to this specific car, while we cannot find too much fault in the road car design in terms of execution, again, we feel like this isnât quite high enough on the sports car - supercar - hypercar scale. For the race car, on first glance it doesnât look too bad, if not a bit tame looking because of the car its based on. On closer inspection we do see some things to pick on, like the lack of side cooling intake and air exit on the back for venting those air out - how are you going to provide cooling for all that power? Overall the aero make sense for the most part, but the flat plate splitter, boxy skirt design and the single element wing all seem quite tame, and weâd like to see aero that pushes things further.
TOM
Looking at this sketch, we like how its reminiscent of the aggression of something like the Brabham BT62, which is what we want to see. We really like the through-flow aero idea you have for the front.
The actual car thoughâŠ
The idea is great, but the fixture choices and placement takes away a lot of the aggressiveness that we like from the design, and made it a bit boring to look at. We also think that it might have to do with the sketch having a look that is angled inwards, and the actual car being more vertical.
A lot of what we said about the previous car also applies to this, as in there were some attempts to make it special looking, like the through-flow aero, the winglets and the side openings. But ultimately, we think it falls short of what can be done, and we would recommend you to experiment with changing the shape of the body and make this a special looking design.
Not Tristella
Right off the bat, we are hooked by the front end design, especially those headlights. However, weâre less sure about the sides and the rear. Judging from the body choice, we think youâre going for something inspired by the greats of the past. While designs like the Enzo or Zonda are certainly timeless, we feel like your side and rear looks a bit dated, because of the somewhat clunky shaping and a lack of visual depth.
For example, you can easily tell that this is supposed to be a modern car
This on the other hand weâre not so sure
The squared-off rear end of the body also dates it by a bit, as well as the chunky lower bodywork behind the rear tires. Weâre also not quite sure about what the kidney shaped pair of cutouts on the engine deck is for.
Looking at it for a bit longer, we also felt like the front mouth on the car is a little bit jagged looking. On the plus side, we think this car makes sense for the most part in the aero department, although for the race car youâd obviously have to make a lot of changes and push things much further.
Overall, we really like the front design, but the rest seem a bit lacking in our opinion. Despite our lukewarm reception to it, with some reworking, we think this has the potential to be one of the best cars so far.
MountainGoat
oh boy.
It took us a while to figure out if this is the road car or not, but we see the license plates, so we assume that it is.
First of all, you miiight want to chill out a bit with the LED placement on this.
Having no less than three types of LED patterns in the front is a bit too much, and instead you may want to consider giving out some real estate for projectors instead of LED lines.
How would this vent work aerodynamically anyways, as itâs placed right in front of the tires?
Aside from that, the aero seems quite functional for the most part, like the turning vanes behind the front wheels and a generous amount of diffuser space, but we did see some weird things:
like this thing that seem to sit at too steep of an angle, which would act like an airbrake thatâs constantly on, increasing drag.
not quite sure how these would work either
the top-intake sidepods does make sense, but there needs to be a longer distance between the intake and air exit, since yknow, air needs to go into a radiator or intercooler before it comes out. Also, that scoop attached to the side of the car seems, well, tacked on.
Those holes over the fenders are a common theme on your designs, and if I remember correctly you said those are supposed to be inspired by parametric designs like:
Though at the moment, it just looks like well, a bunch of holes. Youâd have to up the density to get that kind of effect that youâre looking for.
We also saw your LMH race car in the wild, but weâre not quite sure if its your actual entry, becauseâŠitâs on a different body
For the road car, overall we appreciate your attempt of making it a more functional design compared to your original concept, but elements like the front and rear light design give it an almost toy car feel to it. We like it overall though.

The boys back at the Alfa Romeo factory might need to improve their communications, as there are two separate Alfas in this challenge?

Not to be too pedantic, but Glickenhaus has sold their first of the road going 007 LMHs
Vanwall and their Vandervell Prototype are also intending to sell a road-going version of the Prototype.

IMO those are examples of road cars related to race cars, more than race cars related to road cars.

POV: Youâve been waiting the feedback round for two+ weeks only to have your car called a watered down Valk.
Thatâs more in line with what is expected for this round - the nose brings to mind a giant filter-feeding (cartilaginous) fish, and makes it look like it will devour its opposition on both road and track.
