Everything
Basic Format
- 6+ hour endurance race.
- Three drivers representing each eligible series form the driver teams for a single car.
- Each car races for the outright win
- Alternatively (possibly in a second class but equal machinery), drivers may be organized by nation of origin if they are of measurable talent but do not compete in an eligible series (i.e. China, Most middle eastern nations, etc).
Series Invitations
Series-count invitations are sent out based on the amount of major regional series that participate in the country. Series that are seen as mostly stepping stones are disqualified.
USA would get three for NASCAR, Indycar and TUSC
UK would get two for BTCC and British GT.
Germany would get two for ADAC GT and DTM.
Italy and France would also get two. Most other European countries would get one, with a total of ten (or less) being extended.
While these invitations are initially earmarked for a series, should no teams respond, then another team from another series may accept on their behalf. This includes smaller series as well (i.e. Xfinity, Formula 3, Carrera Cup, PWC, VLN, etc).
Nations Invitations
Countries that do not get a "Series Invitation" will instead get a single "Nations Invitation". These include China, Russia, Switzerland, Ireland, Norway, Finland, UAE, India(?), South Korea, etc. These countries will only receive invitations should they request them (i.e. they have enough drivers with the talent to represent them and have deemed it so). The assembly and organization is handled by a team originating from that country.
Additionally, if the drivers representing a country's series number 2 or less for those countries with multiple series, or 1 for those with only a single entry, then that country may be given an additional "Nations Invitation".
Example: Lets say Italy gets six drivers from two series together and only two of them are Italian, they can get an additional invitation as long as all of the drivers are Italian.
Lastly, if any Series Invitations go unheeded, it may become a Nations Invitation instead.
Japan would be the sole exception, getting 1 Series Invitation and 1 Nations Invitation, as I don't think they have enough qualifying series, but more than enough qualifying drivers.
Driver Selections
Ideally, we'd all like to see the best drivers from each series go at it, but the more likely and practical option would be to have a team respond and offer up it's drivers, as long as the team has won a championship in the past five years, as well as one of it's drivers.
This opens up the door to allow easier sponsorship deals, and even the cars could get branded bodywork based on the manufacturer they race for (but this would be developed internally by the series).
Cars entering via a Nations Invitation must have a livery based on the national racing colors of their country.
