1972 Orisian Touring Car Championship
HOMOLOGATION PHASE
For almost two decades, sportscar racing had been the main focus of the motorsports scene in the (fictional) continent of Orisia. As the Sportscar Championship started moving towards prototypes in the early 70s, manufacturers pushed for a new series based on production cars.
Eventually the Automobile Racing Club of Orisia (ARCO) listened to the manufacturers and in 1972 the first season of the Orisian Touring Car Champioship took place.
The championship is split into three divisions based on engine displacement: 0-1300cc, 1301-2000cc and 2001-5000cc.
HOW IT WORKS
This challenge is divided into two parts. For this first part you need to build a road car according to the homologation rules (see below). Then when the homologation period ends you can focus on modifying the car to be race ready.
There’s also the option of entering a privateer team with a car based on someone else’s homologation model.
The important stats for the race are:
RACE PACE
- Lap times: Your in-game lap will be your fastest possible lap.
- Sportiness: Higher sportiness will make your laptimes more consistent and closer to your optimal laptime.
FUEL
- Fuel Economy: Cars that use more fuel will have to make more pit stops.
- Wheelbase: Bigger cars can carry larger fuel tanks.
MISTAKES AND PENALTIES
- Drivability: If the car is too hard to drive, it will have a higher chance of crashing.
- Reliability: To finish first, you must first finish. The lower your reliability the higher the chance to lose time in the pits.
Some RNG will also be applied to each lap.

DESIGN CONTEST
There will be a public voting to decide on the best looking car. The winner of each class as well as the best looking privateer car will win an additional free entry for a single race of their choosing. These free entries ignore the three car limit.
I will also choose my favorite out of the cars that didn’t win and grant them a free entry.
TEAMS
There are two types of teams that can be entered into this championship:
- Factory teams: Racecars entered by the same user that made the homologation model.
- Private teams: Cars modified by a different user than the one who submitted the homologation model. Private teams will be asigned a car at random from all of the available models.
If you want your car to be available to privateers you have to specify it when submitting your homologation car.
Factory teams have a budget of $85000, while privateers have $73000. This is calculated using the price and service costs of your car as well as how many cars you’re entering in each round of the season. Each team can enter a maximum of 3 cars in a race.
