And with the final field set at 17 challengers, here are some insights regarding the design choices made.

There are 11 different wheelbases ranging from 216(Zen Motors Tianshi) to 254(apparantly automation rounds this value down, making the Butler Pixie a legal car.)

Apart from the Pain(@OptimusAlpha ) everyone chose the logical Monocoque chassis. Pain is a partial monocoque.

Also the odd one out, the Clari Aigu was the only one finding the need for galvanized chassis while all the others are steel.

Steel panels were more occurent than partial aluminum 11 to 6.
10 cars have a longitudinal placed engine against 7 transverse.

The most used front suspension is the Macpherson while the most used rear is the Double Wishbone.
This was also the most common combination.
There are a few trailing arms and even one torsion beam and ā€¦ yes ā€¦ a Coil Solid Axle

TRIM STATS

Drive types:
FWD : 5
RWD : 5
AWD : 7

7 cars use a diff, 10 donā€™t.

6 cars come with ABS

Passive springs win with 12 vs 5 Progressive ones

Gas Mono-tube is the most used damper

2 participants decided the medium tire was the way to go(the rest prefers sports)

Surprisingly only 6 cars have the max allowed width on their tires. The thinnest is at 155 from the Pain.

All brake types were used both front and rear.

Average car weight is at 987 Kg
The fat award goes to the Bricklet at 1118 and the undernourished one is the Tianchi 550S at only 735kg.

@Sigg610 s FPV sprint is the one making the most use of the available downforce while most completely ignored this possibility

quite a wide range in terms of engineering solutions.

44

Oh wow people are talented, 200hp is impressive given the regulations

45

Iā€™m actually proud of the Tianshi. Maybe the powerplant will hurt me, but, being both small and lightweight may make the Tianshi one agile little car.

Also, yes, I am the one who made the underpowered Kei Car.

Hi Millan !

Ah damn, another challenge I was keen on entering but didnā€™t get the time :frowning:

Excited to see how this goes. Some of these cars looks super cool!

Never understimate the creativity of some people :wink:

These are the people I need to keep in consideration while making the rules :upside_down_face:

I have finally managed to practice a bit around with all the cars and yes, it might be tight at the top. Lots of solutions means lots of different styles of car. We got understeery fwd, awd chunkies, and oversteery sports rwd cars.

I hope to have time this week to give proper attention to all the cars. Iā€™ll start with the uglier ones and work up to the better looking one, this way the better and more appropriate designs get a tiny little bonus.

While Iā€™m driving the cars Iā€™ll release the list of bonuses and penalties which youā€™ll have to choose. This will be an extra personal rule added to the already existing rule set.

Due the large amount of participants, Iā€™ll eliminate cars as the competition progresses. But everyone will participate in at least 2 rounds(this and the next). This is because I really want to put time and attention in the proper driving of all cars reducing the luck element of me being tired or not focused enough for a particular car.

That said. At the end of round 2, 3 cars will be eliminated, then another 2 at the end of round 3 and another 2 at the end of round 4. This means the final round will have 10 cars.
(another reason for this, is to discourage sandbagging to gain a bonus for the following round :wink: )
round 1 2 3 4 5
#cars 17 17 14 12 10

That said, I want to thank everyone for their submissions. Itā€™s pretty fun to be driving all these cars and am looking forward to see how the challenge progresses.

soon:
< list of penalties/bonus to choose from
< face-lifting rules and procedure

This was the most fun Iā€™ve had designing in automation, the tight regulations makes you think hard. Considering the stats donā€™t think in competitive, still fun anyway.

So our sport department managed to book one test day on a busy Hirochi Circuit. Our test drivers did some laps and mechanics made some adjustments to the car before handing it in to the challangeā€™s parc ferme.

Here is a short clip from our test day.

I have updated the main post with the facelifting rules and the available bonuses+penalties for the upcoming round.

What I need from you now is to send me an ordered list from the bonuses/penalties. (If you happen to be the worst performing car, you receive what you chose on #1, if you were the fourth slowest, you might still receive any of the 4 favourites(it will depend on what the slower cars than yours have selected)).

The best 5 cars of the round will get a penalty and the 5 worst will get a bonus. This increases the difficulty setting for the best engineers while easing it for the not so best.

Example of a list:

  1. extra 100 available for service costs
  2. minus 5 on min safety requirement
  3. extra 500 for trim material cost
  4. extra 50 for service costs
  5. extra 200 for engine material cost
  6. + 5 PU engine
  7. plus 5 on min drivability requirement
  8. minus 100 on trim material costs
  9. minus 50 for engine material costs
  10. minus 200 on trim material costs
  11. minus 5 trim ET available
  12. minus 300 on trim material costs

This will be an addition to the base rules. So letā€™s say you choose and receive the ā€œminus 300 on trim material costsā€ penalty, this means your total material costs for the trim for this round will be 3700 instead of 4000.

Iā€™m pretty sure Iā€™ll be done with all the cars before the weekend is over so send me the list via DM before that time.

Also, if it is of importance which track will be used for the 1989 round for the ordering of the penaltiesā€¦The next track will be Lime Rock Park

This is reminder to dm me your ordered list of the penalties/bonuses as stated on the previous post.

Also, please read the ā€œFacelifting rulesā€ and Available Bonuses/penalties paragraphs in the main post of this thread.

I have driven all the cars and as soon as I have all the lists from everyone, I can release the results and you can all start working on the 1989 round.

Here are the results for the 1987 Round at Hirochi Short.

The clear winner was the Taka Peregrine STV from @KenShiro . The Peregrine is both a combination of fast and easy to drive, and also perfectly tuned for the windy Hirochi corners.

The underdog award goes to @AndiD (Seongu Gran Kando 1.3i) for his 5th place while have the 2nd least powerful car of the field.

The Untamed potential award goes to @Deltaz with the KBF Pruttmobil for making on paper an awesome car(and good looking) but having just being ā€œsomewhatā€ undrivable at Hirochi

The ā€œIā€™m doing it my wayā€ award goes to @stigx24536 (Millan) for managing a 2nd place while submitting a Carbs engine on a car with only 185 wide tires and no downforce.

Other insights:

  • cars with Downforce did in average better than the ones without
  • Non inline engines struggled mightily on this round
  • Tire width was a big factor in this track. Grip is a real thing guys :wink:
  • Medium compound tires were not a good choice on this track
  • The podium all used magnesium rims
  • The use of differential was not a deciding factor
  • There were no RWD cars in the top 10

Question about the facelifting part, Iā€™m assuming we can only make minor adjustments or are we allowed to do major revisions within the regulations.

56

In the campaign, when one does a facelift, the ET gets determined by the amount of changes from the previous trim, but since thatā€™s not the case in Sandboxā€¦

I did think about setting a limit on the amount of changes one can do between rounds, but at this stage of the game development(automation, I mean), is not possible to track engineering changes in Sandbox. So for now at least, the only things you cannot change are the Model Body, Chassis choices(chassis material, panel material, suspensions type, engine orientation) and engine family(layout, block and head material, head type, cylinder count, number of valver and family bore or stroke.
All the other things can be changed, like drivetrain from rwd to fwd or awd, fuel systems, exhaust types, header type, all components sizes, dampers, seating, etc etc

If you follow the procedure I posted in the main post, the things that youā€™re not allowed to change should already be locked(in sandbox you can still click on the unlock button, but just donā€™t :wink: )

Also important: The added rule is an addition to the main set of rules, and not to the relative value you used on your previous round. This means for example, for @OptimusAlpha that the rule that says ā€œMax material cost: 1.2Kā€ is now for him ā€œMax material cost: 1.4Kā€

The way I see it, yes, it would be preferable to limit the amount of changes to look more realistic, but the current situation means that everyone is working on a different puzzle in order to optimize it the most, and the ones who already got better cars and need to change less are already in a position to further optimize it(and got the championship pts aswell) while the other are still trying out stuff to catch up in development.

sounds good when is the time limit to submit the facelift?

58

Deadline for facelifted submissions for the 1989 round is Wednesday 24th at 23:59 GMT

I promised a week in between rounds, so here we go. And remember, this is a much faster track, so donā€™t forget to tune your cars accordingly.

59

And hereā€™s an automation update mid challenge again. I donā€™t think it changes anything on the automation stats part, but it may have made changes to how it will handle in Beam(changes were made to the exporter, mostly to fix stuff)

For those who have already submitted(only 5 so far), feel free to resubmit(or not).

And for the rest, 3 DAYS remaining!

60

Also, feel free to let other know how your facelift for this round is improved(or just different) than the previous round.
