The Vermin Design Team has released a first demo of their Formula 5000 mod for rFactor. The demo includes one car in three different variants and is very much alpha.
The Formula 5000 was designed as a low-cost series for various cars not fitting into any particular formula. Manufacturers included notable names such as McLaren, Lola and Lotus, the cars were powered by engines up to five litre capacity (hence the name).
If you tested it, please make sure to leave the team some feedback in this RSC topic as the reason for the release is to get as much community feedback as possible.
