    Since both BeamNG stock content and repository cars seem to be very road-oriented, I decided to make a series of track-oriented cars in Automation.

    All of them have endured extensive testing and tuning at brands hatch, spa, suzuka and nurburgring, with and without ABS (the only aid they got), using a Simucube 2 Sport DD wheel and Fanatec CSL v3 pedals.

    I divided the cars in various categories and packs, to help differentiate between them:

    Sport - small-ish engines on not too stiff sport chassises, lightly tuned coupes, or track prepared small cars
    20210823173211_1.jpg 20210823175507_1.jpg 20210823175634_1.jpg 20210823180846_1.jpg 20210823182314_1.jpg 20210823183248_1.jpg 20210823184814_1.jpg

    1: This little car is glued to the road, it's almost weightles and can be really fast out of corners despite the small engine
    2: it got a big turbo engine from a rally car, the massive torque needs some attention in using throttle out of turns
    3: it has the same small engine of the Sport1, but the chssis is more oriented to mechanical grip, with low aero, longer wheelbase and big tires
    4: What if a BRZ chassis got a powerfull engine and an extremely low weight with perfect 50:50 distribution?
    5: the boxer engine and the good weight distribution make this a very easy to drive sports car
    6: looks like a porsche, but is front engined and doesn't really handle like one, is very predictable instead
    7: A fun to drive japanese coupé, willing to drift every turn

    Super - bigger engines, bigger tires, more aero, but still driveable on a road
    20210823172733_1.jpg 20210823173441_1.jpg 20210823185834_1.jpg

    1: same chassis as the Sport 3 with a lot more aero and fattier tires, it might feel a bit underpowered, but watch out, it gets to speed very quickly!
    2: sharing the chassis with Sport2, it features a very nervous i6 turbo engine, once you learn to tame the engine it can be really fun to drive and more precise than you'd expect
    3: this relatively low power V8 NA coupled with the low weight will make for an excellent handling car

    I also made some videos with the test of all my cars on suzuka:

    Sport and Super cars


    Touring and Hyper cars


    '90 Silhouettes and Supertouring


    Rally cars on tarmac and drift cars at drift playground track:



    I TOOK QUITE SOME TIME TRYING TO RE-ADJUST THE THREAD, BUT IT KEEPS SAYING IT HAS SPAM-LIKE CONTENT AND WON'T LET ME UPDATE THIS POST OR THE OTHERS WITH A WELL-DONE DESCRIPTION.
    CAN SOMEBODY PLEASE HELP ME? I'D LIKE TO KEEP THE THREAD NICELY ORGANIZED BUT IT'S JUST IMPOSSIBLE RIGHT NOW.

    I made a very minor update to some cars because they were overheating brakes too much, so all the rally cars and some others got bigger discs and lower brakes quality as this seems to help with the cooling (brake cooling in the aero tab is maxed out already in most cars and just adding bigger discs makes them lock brakes).

    Also made another rally prototype, this time on a chassis that allows some decent ride height for an even better offroad handling - now in the rally pack

    EDIT1:
    *OUTDATED, ALL RALLY CARS GOT IMPROVED AFTER THIS VID*
    I also made a video to show the rally cars and will soon do one for the track ones too

    Again it won't let me update the previous post because of spam - can any moderator help me with this? is quite difficult keeping updated different posts with different attached cars.

    Anyway, updated most of the rally cars in the previous post, with expecially "rally 4" having got quite some changes trying to improve agility; all of them got little underbody aero to lower aero center of pressure, helping with roll and pitch.

    I also made 4 new cars: two Gr.B inspired modern rally cars and 2 '80 cars, soon to be joined by at least 2 more from that era.


    20210827153520_1.jpg
    Rally RWD
    modern take on a RWD extreme rally car, very usable engine, 600+ kg of downforce to the rear, and very agile once you learn to modulate throttle during turns

    20210827153929_1.jpg
    Rally 5
    I made this to beat my own record on the Behemoth Italy Time Trial (download it! https://www.beamng.com/resources/italy-rally-time-trial.17392/), not the most powerfull, but the mid-engine layout and its incredibly smooth V10, together with the ultralight chassis, make for a really good offroad handling

    20210827163027_1.jpg
    Oldschool rally - now in the rally pack
    inspired by 3 '80 classic cars, it gets an NA i6 carburators engine and viscous LSD for a very neutral and easy handling

    20210827153632_1.jpg
    Oldschool drift - now in the drift pack
    Same chassis as the other, but this one gets bigger, semislick, tires, RWD, a bit lower weight and a small turbo to help the engine give great torque across all the RPM range, making it the perfect drift car for beginners!

    Another pack of cars; this time i wanted to recreate some racing series with a nice variety and close laptimes and feel.

    The first is the silhouette series, in which we get 5 cars good for 1.28 on nurburgring short track - 2.10 on suzuka GP:

    20210904162130_1.jpg 20210904162250_1.jpg 20210904162415_1.jpg 20210904162537_1.jpg 20210904162623_1.jpg

    The AWD EU silhouette is inspired to early '90 DTM cars, with a 3200 NA engine, viscous differentials and extremely low weight.
    The AWD EU silhouette mid, as the name says, is mid-engined for an even better balance, mechanically the car is very vaguely based on what would have been the Italian attempt at the procar championship if it wasn't cancelled, but the aesthetics is very different.
    The AWD JP silhouette is inspired to the most famous JSGT car, with electronic differentials and a very rearwards torque distribution.
    The RWD JP silhouette also comes from the JSGT championship and can easily be the fastest of the pack, but also the most unforgiving one.
    The RWD EU silhouette is inspired by the LM version of a famous italian supercar, but without the turbos to bring the laptimes in line with the other cars of this category.


    The second pack is inspired to the super 2000 cars, again offering 5 options good for 1.42 on nurburgring short - 2.30 on suzuka GP

    20210830024807_1.jpg 20210904161156_1.jpg 20210904161444_1.jpg 20210904161615_1.jpg 20210904161706_1.jpg

    The RWD one is inspired by the only RWD partecipants of most touring championships, it wants to be driven precise to be fast, but can be fun to drive dirty.
    The AWD EU one sports viscous differentials for a very easy and forgiving handling, but it's also a bit understeering.
    The FWD EU one is the lightest and you can really push it into turns with little understeer thanks to the torsen front differential.
    The AWD JP has modern electronic differentials for a great traction and agility
    The FWD JP one is more understeery than its EU counterpart, but compensates with engine power and chassis stability


    The last two cars are a lightly tuned and a full race version of a famous french hot hatch. They may look small and underpowered, but there's a reason people use this car in most hillclimb races: it's FAST - now in the fun cars pack
    20210829214035_1.jpg 20210830025020_1.jpg
    The tuned version can do the same laptimes as souperturing cars. On sports tires.
    The race prepared one shaves another 3 seconds thanks to some light aero, much bigger tires, and a small turbo.

    I also made a massive overhaul of the hyper 6 car, to make it a lot more driveable, but a bit slower

    The prototype pack is now in the repository!
    https://www.beamng.com/resources/htk-prototypes-pack.19768/

    here you can also download the last two ones i'll put in the pack - both still need finetuning and can break your wrists if using a direct drive wheel (believe me, i'm not joking!)
    20210912170458_1.jpg
    too much power for it's own good, coming with some turbo lag too


    20210912160551_1.jpg
    another one powered by the 1400hp v10 turbo


    As the next car pack, should i do some prototypes to go with the silhouette pack or some GTs to go with the prototypes i made?

    Hi all, I've made no more updates in recent weeks because I got many things to do in real life, but I'm planning for a full revision of all the content i made + 3 GT3-ish cars and one modern DTM-ish.

    What I'm planning to do for each pack of cars is this:

    - more refined fixturing to bring older car on par with latest ones
    - replace most "spoiler" and "lip" fixtures with ones that actually make downforce, then re-tune downforce to appropriate levels
    - full revision of brakes to make all cars handle good without ABS
    - give a livery to the cars that require it

    I may also do some race variants of my trackday cars and trackday variant of the racing ones.

    I'd also like some help on driveline editing to make something: is there a way to make something like this?

    electric engine -> reduction (single-gear gearbox is ok) -> electronically controlled clutch -> combustion engine.

    This first thing should be easy to do, but then i'd want to be able to write a custom script taking as input combustion engine's RPM, electric engine RPM, turbo RPM, and throttle, and giving as output binary clutch state (open/closed) and a separate throttle signal to the two engines. Bonus points if the script can also have an internal "state" that it updates at every simulation timestep. Double bonus points if the electric engine can also recharge itself by braking when reciving negative throttle input.

    EDIT: here is my new DTM car, that's the fixture quality i want to bring all the other cars to in the next days

    EDIT2: first car updated:

    EDIT: changed some bugged ads on the liveries and updated the repository cars (waiting approval). DTM car is also now on the repository.

    EDIT2:
    here's a video showing the latest handling and fixtures update on supertouring cars, i'm also removing the cars from here since the repository package is now up to date (link in first post)

    The rally car pack is now waiting for approval in the repository, all the cars got a last physics and aesthetic revision.
    20211018134835_1.jpg 20211018133904_1.jpg 20211018134018_1.jpg 20211018134149_1.jpg 20211018134336_1.jpg 20211018134504_1.jpg 20211018133522_1-Copia.jpg 20211018133628_1-Copia.jpg 20211018133404_1.jpg

    I also made another rally car inspired to an '80 GrB car. I'd like to also do a mid-engined hatchback but couldn't find a body that allows it.
    20211018133715_1.jpg 20211018133756_1.jpg 20211018133722_1.jpg

    I plan to also make a tarmac version on sports tires for each of this cars. If there's the request i may also make a track version on semi-slicks for some of them.
