The Rally di Fruinia is the spiritual successor of the Corso di Fruinia. It was after the 1968 incident that the organisation decided to no longer organise the competition on the open road, but instead limit itself to staged events.
The 1973 edition will consist out of a qualification event, followed by 3 championship stages. Cars from all seven classes will race each other, both within class on the basis of a points system, as in total on the basis of total time.
PLEASE READ THE REGULATIONS CAREFULLY
Class Specific Regulations
General notes:
Each forum user can submit one car per class.
Cars might be for both Class C0 as well as C1, and C5 as well as C6. You must chose one, please indicate in the post and in the PM.
Specific Rules:
Summary
C0 up to 750 cm3
maximum tire width of 135mm
minimum weight: no limit
C1 up to 1150 cm3
maximum tire width of 145mm
minimum weight: no limit
C2 from 1151 cm3 to 1300 cm3
maximum tire width of 165mm
minimum weight: 700kg
C3 from 1301 cm3 to 1600 cm3

Note: Exceptions to the safety requirements can be requested to adhere to the minimum weight threshold. These shall be decided on a case-by-case basis. The main criterion will be plausibility and technical consistency of the design.
Common Regulations
General Design:
Summary
Cars must be modified production models and have a place on the rear that can hold a licence plate (it is sufficent you use a vent/grille in the body colour to indicate where it would hang, an actual licence plate is not strictly required).
Cars shall have a unique number on flank(s), and bonnet, truck or roof (in the 00 or 000 form only)
Cars shall be two-wheel drive (rear-wheel drive cars will be driven with 13psi tires on dirt roads for extra grip).
Cars must be realistic and affordable, meaning:
One fixture / lazily-made cars will not be accepted.
Unrealistic quality spam / min-maxxing will not be accepted.
All cases will first be discussed with the entrant and if deemed necessary escalated to the broader audiance before the non-acceptance is final.
No further restriction on budget or quality sliders apply, but avoid extremes. I accept liberal use of negative quality as representing stripping the car for race preparation.
Engine design:
Summary
Use of the DOHC 4-valve engine shall be prohibited
Engines can run on Regular 91 or Leaded 92 RON commercially available fuels.
No catalytic converter or mufflers must be fitted (but they are allowed if you so choose).
Engine sizes within the specific rule set are calculated on the variant size, not the family size.
Drivetrain:
Summary
Cars shall be fitted with a manual gearbox with at least 3 forward gears and one reverse gear.
Alternative gear ratios may be suggested in the PM to me, I will mod them into BeamNG when possible.
To repeat: only two-wheel drive.
Wheels:
Summary
Cars shall not be fitted with offroad tires.
Cars shall have a maximum rim diameter of 15 inches.
Please take care of maximum tire width.
Brakes:
No restrictions.
Aerodynamics:
Cars shall be fitted with an offroad skid tray, no further restrictions.
Interior:
Cars shall be fitted with 2 sports seats, no entertainment and -5 quality.
Driving Aids & Safety:
Summary
Cars shall not have power steering.
Cars shall be outfitted with basic safety and -5 quality.
Exceptions to the safety requirements can be requested to adhere to the minimum weight threshold. These shall be decided on a case-by-case basis. The main criterion will be plausibility and technical consistency of the design.
Suspension:
No restrictions.
Explanation of competition and submission continued in post 2.
Only 8 cars per class with continue to the actual championship. To determine which cars, all cars will be given scores on the basis of performance and design.
Two times laps around the Small Island - Island Loop Alternate (tarmac - bad quality) - though lore-wise Targa Frucilia: cars will be given 20-16-14-12-10-9-8-7-6-5-4-3-2-1 points for best time and down.
Cars will be scored out of 20 on the basis of the following parameters:
Design (subjective): /5
Technical coherence (either realistic or plausible within known company lore): /5
Budget used (average and cheaper will be 5 - every 10% more expensive will be -1): /5
Drivability (subjective): /5
The eight cars with the best scores /40 progress to the Chamionship.
Chamionship:
3 stages:
East Coast, USA - Backroads Course 1 (gravel - light; and tarmac - good quality) - Lore-wise Coma - Naefolli.
Utah, USA - BRC Dirt Stage 2 (mod) (gravel - rough) - Lore-wise Targa di San Marco.
Jungle Rock Island - Mountain Stage (tarmac - bad quality) - Lore-wise Bruscilia - Tomo Vecchio.
Here, random chance plays a roll as well:
Engine reliability will be the basis for random mechanic issues and time loss.
Trim reliability will be the basis for random incidents and accidents and time loss or DNF.

Would you consider a group B-style combined tyre width restriction?
I would also look at the C2-C3-C4 weight/tyre balance–just theorycrafting, but gaining 50kg/20mm from C2 to C3 and then 100kg/10mm from C3 to C4 seems odd. (I haven’t built cars to them, so ignore this if you have experimental evidence for those tradeoffs.)
1973… I may have a car or two to pick from. They are Sinistra Lore cars, (though neither made it into the lore thread due to computer problems during that particular challenge), so they will be FWD. The engine, however, is 3.9 liters of V6, so… Yeah, we’re a little on the big side.
But I think I can manage to get the Generation 1 Sinistra Traville into this with a bit of minor tweaking.
I was inspired by Group A and B restrictions, I settled on these on the basis of a few test mules I built. Again, stages are low speed, tight, and twisty affairs. It is no coincidence that a low class, relatively low power/weight ratio car won my Corso di Fruinia challenge. Light and small engined with useful power I expect to reign supreme again.
(On that note, general hint to those who read this. Short gear ratios. Don’t get tricked by what Automation tells you. No one needs to go 70 km/h and up in first gear in rally.)
Maybe yes, maybe no. Maybe that’s an invitation to suggest a backstory.
I get why such valvetrains are banned outright for this challenge - they’re too complicated and new-fangled for 1973. However, are 2-valve DOHC valvetrains allowed?
I leave that up to preference and lore. I took that from official historical regulations, where it simply stated the cars must be able to run on locally available commercial fuel.
Yes, not sure they’d give you an advantage on dirt roads though.
Basically the minimum weight limits are a hidden limitation on the bodies that you can use per class. Basically I don’t want a light aluminium sports car with a 4 litre V8. I just want to open the rally up for the big American boats in people’s lore should they so wish.
I understand the request though, and shall add the following to the rule set:
Exceptions to the safety requirements can be requested to adhere to the minimum weight threshold. These shall be decided on a case-by-case basis. The main criterion will be plausibility and technical consistency of the design.
You ask it as if you just read the most unreasonable thing in the world. Number can be 00-99 (or 000-099) and (100-999). You cannot have a car with number 1 or 1000. You can have a car with 01 or 001.
Luckily the game does this for me. I just read it of the market tab with 0% mark up.
Correct, I decided them to be unrealistic. 2-valve DOHC were used, mainly in Italian engines, IIRC. So, yes, those can be used.
to counterpoint to that: Nissan, Ford, and Lotus all had 4 valve DOHC engines in full production by 1973. and Triumph had a 4 valve SOHC at that point, too.
not to mention that Alfa Romeo and Duesenberg started using 4 valve on select road cars in the late 1920’s.
Which is why you can use all the SOHC 4v you like.
The DOHC 4v I get the point, but I want to limit min-maxxing. I consider them a bit too overpowered in this time period. Plus I want people to be allowed to use SOHC and OHV where it makes sense and fits lore, without handicapping themselves.
