Era: one of five

1973: the championship starts

World Championship and Group 4 · 1973-1981

Sourcing: every date and figure below is drawn from this project's own research briefs, which cite period sources, championship archives and season records. Where a number is a design decision rather than a historical fact, it says so.

What the era was

The world championship began as a competition between car makers. Drivers were not part of it.

The championship was founded for 1973 on the bones of the International Championship for Manufacturers, which had run 1970-1972 and whose nine rallies were carried straight into the new calendar. The first round, the Rallye Monte-Carlo, started on . Thirteen events ran across four continents, from Monte Carlo and the Safari to Poland, the 1000 Lakes, Press-on-Regardless in the United States and the Tour de Corse. Alpine-Renault took the first title with 147 points; Fiat and Ford followed on 84 and 76.

There was no drivers' title of any kind. Not a lesser one, not an unofficial one. None. A driver's career was measured in works contracts, start money and national fame.

The rules that defined it

DateWhat changed
1970 Group 4 redefined as special GT cars: 500 identical cars in 12 consecutive months. This is why every serious manufacturer had to build a road-going run to go rallying.
1973 Championship founded, manufacturers only. Points 20-15-12-10-8-6-4-3-2-1, and only the best-placed car of each make scored.
1974 The oil crisis cuts the calendar from 13 events to 8. Monte Carlo and the Swedish Rally are cancelled outright; both return in 1975.
1976 Group 4 homologation relaxed to 400 cars in 24 months. The 16-valve-head graft is outlawed.
1977 The FIA Cup for Rally Drivers begins. Not a world title. Twenty qualifying events, best eight results counting, capped at five world rounds, two European rounds and one special. Munari 31, Waldegård 30, Darniche 27.
1977 Manufacturers' scoring becomes a composite: overall points 10 down to 1, plus group points 8 down to 1, and the car had to finish inside the overall top ten to score at all.
1978 Second and last FIA Cup, won by Markku Alén. The two-valves-per-cylinder rule takes full effect, killing the 24-valve Stratos head.
1979 First World Championship for Drivers. Points 20-15-12-10-8-6-4-3-2-1 on overall position, all twelve rounds counting. Waldegård 112, Mikkola 111: one point, decided at the final round.
1981 Ari Vatanen wins the drivers' title in a privateer-run Escort, 96 to Fréquelin's 89, while Talbot takes the makes title. Four-wheel drive has arrived and the era is over.

What a weekend looked like

Marathon distances, and attrition as a headline statistic. Monte Carlo 1973 was still a concentration rally: crews set off from about nine European cities, the total route ran to 4,800 km with 18 special stages making up 420 km of it, 278 cars started and 44 finished. The Safari was roughly 5,000 km entirely on open public roads, averaging over 100 km/h, with bull bars, snorkels and helicopters flown ahead to move wildlife off the route. The Acropolis broke cars over up to 800 competitive kilometres.

Servicing was strung along the road. There was no central park to return to: teams put vans at points on the itinerary, chase cars leapfrogged between them, and outside a scheduled service the crew worked on the car themselves. Practice was effectively unlimited, and the RAC Rally ran its stages blind.

How the game models it

Era rules live in data, never as a year check in the simulation. This span is one ruleset, named World Championship and Group 4, running 1973 to 1981, and it sets the dials that make the decade feel like itself:

The 1977-78 detail is the kind of thing this project treats as load-bearing. A game that quietly awards a world drivers' championship in 1975 has told you it did not look.

Playing it

You start here, as a privateer with a day job, a debt-bought car and a borrowed co-driver. The season is not handed to you: you build a programme out of a global calendar, and entry fees, start money, date clashes and the cost of getting to Kenya are all real decisions. Winning a makes title is not available to you for years. Getting to the finish of one 5,000 km event, with the car intact and the bank still speaking to you, is the early game.
