Assetto Corsa: TRD DRW12 Mod Expands Group C Grid

Assetto Corsa TRD DWR12 Car Mod.jpg
Creativity is running strong in the sim racing community. The latest example is the Assetto Corsa TRD DRW12 mod that expands the Group C grid.

Sports car racing is seeing a new high in 2023. The introduction of the LMH and LMDh regulations for top-class Hypercar prototypes in WEC and IMSA made interest skyrocket again, with numerous manufacturers trying their hand at the premier endurance series in the world.

“Golden Ages” coming and going are a constant in endurance racing. The recent LMP1 age and the GT1 (and then LMP900) era in the late 1990s and early 2000s come to mind – but before that, another class reigned supreme. Group C enjoyed immense popularity from its introduction in 1982 until the early 1990s, ultimately meeting its demise with the introduction of engine rules that were identical to that of Formula One at the time.


While the big players of the era were Porsche, Lancia, Sauber-Mercedes, Jaguar and Peugeot, among others, numerous smaller efforts were on the grids as well. In fact, many Porsche 962Cs were modified so extensively by privateer teams that they hardly resembled the base car. Privateer cars were also present. For instance, the 1989 season saw the Cougar C22S of Courage Compétition and the Spice SE89C by drivers Gordon Spice and Raymond Bellm trying to run with the big dogs.

Assetto Corsa TRD DRW12 Mod: The Group C Privateer Spirit​

It is this spirit that RaceDepartment user @iballobar13 channeled for their Assetto Corsa TRD DRW12 mod – their first-ever mod, actually. Only released on November 10, the fictional Group C car fully leans into the mechanical variety found in the era, sporting a twin-turbo W12 engine instead of a more common V8, V10 or V12. At full boost, it chucks out close to 900 hp.

The car’s body is unique but fits in with other cars of the era. It follows the design philosophy of the time. That means a big rear wing, ground-effect bodywork and a closed cockpit – with rather small side windows. A longtail Le Mans-spec version is also available as part of the mod.

According to the mod’s description, the DRW12 has been desgined “to race toe to toe against Sauber’s mighty C9”. As a result, iballobar13 has conducted extensive testing so the car is a match to its competitors AC.

Careful on the throttle! The DRW12 tends to slide out the rear under power on low RPM.

Good Match & Unique Characteristics​

But how well does the DRW12 get along with the other kids on the Group C playground? Well, it is a good match for the C9, the 962C and the Mazda 787B. While the Sauber-Mercedes has the upper hand on top speed, the TRD is a bit more agile in the corners. iballobar13 claims that their creation is “within 1s of the Sauber”.

The car also has its unique characteristics when it comes to driving it. As the W12 engine produces a lot of torque at low RPM, careful application of the throttle pedal is crucial when accelerating out of slower corners. As a result, the first few laps can be quite tricky. Some setup work can mitigate this, however. Plus, the car does inspire decent confidence once the downforce really kicks in.

The DWR12 has been tested extensively to match up well with the other Group C cars in Assetto Corsa, like the Sauber Mercedes C9.

Despite being fictional, the DRW12 mod features detailed car specs. These include its suspension layout, chassis material and even its valve train. This is not by coincidence, though. iballobar13 claims to be studying Mechanical Engineering and intending to use the car as a test bed for different rear wing configurations. They could later find their way into the mod. The attention to detail even extends to the twin-turbo W12 having been constructed in Automation, a very intricate car-building simulator that allows for creations to be exported and driven in BeamNG.drive.

Currently, the car comes with three liveries each for both the standard and Le Mans versions. Unfortunately, the engine sound is still a placeholder for now, though a proper W12 sound is going to be added later, according to the mod’s author.

If the TRD DRW12 has piqued your interest, head over to the RaceDepartment download section. There, you can also leave a rating and feedback for iballobar13’s creation. For another mod spotlight, check out our article on the Crystal Palace Circuit for AC!

No matter how much 'special thanks' you give them, it shouldn't be posted here if you didn't get their consent. Granted, sounds are generally regarded as OK to use, but this goes a step beyond that. Largely it seems to be mostly copy pasted physics files of the Sauber C9, with slightly changed physics values here and there.

Lest we mention the entire interior was 'borrowed' from the Sauber as well, not okay.

What are you talking about? He doesn't need any consent as the mod is for the same game which is free to be modded.

He hasn't stolen anything. Your comment is out of place.
 
It’s commonly overlooked, but there is a reason that .kn5 and .acd files are used for models and physics- to encrypt them and prevent them from being used in a similar situation as this. It has been on the ‘rules’ of this site that all content is to be made from scratch, or the used/converted content was used with autorization from the original author. Although said encryption is now as easy to break as just a click in Content Manager, that still doesn’t give the user consent to rehash and reuse this content. As far as I’m aware, it’s generally regarded as OK on this site to reuse assets from the ‘Formula_K’ folder in the game’s dev files, but to reuse and take data from other KS cars was crossing the line between suitable and not suitable for the site. Just because this action is so commonly done doesn’t make the reuse of assets you have no right to use okay.

‘Because the game can be modded’ doesn’t mean I can grab a car from Race Sim Studio, hash a few numbers around, borrow bits of their model, and post it as a new piece of content. These have been the rules of posting content on this site for years, this is no different.

Mod for community --> :inlove:
Douchebags come out of the wood work --> :thumbsdown:

It´s not meant belittling to the commenter's comment in any way

I understand that it's not fair to basically clone other people's work, but that's not what I've done.

I used KS's cars as references (emphasys on references, not ), mostly for tyres and suspensions because how would I know the progressive spring rate of a Group C's car? No idea, so checked the parametres given in these cars and gave it similar or the same values in some cases.

I recognise I leaned on these cars for the deep suspension and tyres coding, there is a lot of complex code and parametres down there, but at any moment I said "Oh ho, let's shortcut and Ctrl C-Ctrl V all this stuff". To start, not even the suspension geometry is the same, so in the begining the car drove incredibly badly, I learned a lot in the process and tried to make all of the physics as well as I could, tweaking those parametres I felt brought the car to how I wanted it to drive, and leaving those I had no idea or felt like had no effect as they were. On the other hand, the idea is to be able to compete with these cars, so the intention is that the tyres have very similar grip and wear properties, so they are purposefully close.

I put a lot of effort in creating this mod, I could have just cloned some car files and change a couple of parametres. That's not what I've done, I've tried to leave no stone unturned in any regards, and I feel like it shows in the behavior of the car and the hard work and detail behind it.
 
We have acquired the rights to the 1989 TRD DRW12 Group C project and Izan will be joining the HSS team to further develop this project with our team's assistance.

We will be developing an entirely new custom interior, custom engine sounds, improving the physics with the addition of many CSP extended physics features and custom Lua code, adding multiple rear wing options, and just generally working to take this project to the next level!

The 1989 TRD DRW12 will be packaged alongside our 1989 Spice SE89C Group C car which is in development as a two car pack released sometime in the summer of 2024.

better be free like it was on racedepartment, and should be reuploaded on racedepartment until you release your "update" There are 2 nice skins released for this car today on racedepartment but now we dont get to try them because of your attention grab.

I was excited for this new company but now I have second thoughts. Removing the original version so you can force people to buy your remake is directly against the interests of the Assetto Corsa community. If your rework is really better people would buy it anyway.

The original was removed due to complaints from the community about non-original content comprising a portion of the mod. We are reworking the mod from the ground up as a fully original piece of content with nothing remaining from another car. Would you have rather had the mod just pulled from Racedepartment with no update coming?

The comments that mentioned non-original content on this article refered to Kunos content and I did not see the problem with using content from the same game for modding. If its against Racedepartments rules I completely apologize for my comments as your totally right. Sorry for the misunderstanding, once your rework comes out I will definitely check it out.

Will that pack of Spice and TRD be free like some of your mods, or will it be paid? If latter, it's kinda bad to take out the free mod and then make it paid. Even with the reworks.
