GROUP 5 – 24H ENDURANCE RACE CHALLENGE (1977)
(Includes Actual Beam Racing)
Sponsored by WidowMaker Industries
BeamNG Endurance Event – Automation Build and Race Challenge
Background & Theme
The year is 1977.
Group 5 (Gruppe 5) represents the extreme edge of production-based motorsport:
silhouette racers derived from real road cars, pushed to absurd levels of power, aero, and endurance capability — yet still recognisable.
This challenge is the opener of the WidowMaker Motorsport Championship (WMC) and serves as the technical entry phase for a 24-hour endurance race event in BeamNG. You can see here: https://youtu.be/L4zpCdPfH-k
Your task:
Design and build a Group 5 race car capable of surviving endurance racing, derived from a legitimate road-car platform, following historic spirit and modern Automation challenge standards.
