With the era and segment this thread is themed after, it might make sense not to allow any transmission type that isn’t an advanced automatic, CVT, or dual-clutch gearbox.
In any case, whichever wins this challenge might as well end up being the daily driver for Tim from CSR162, to go with the Bushido Fuji R he just bought.
Also, with FWD, AWD, and RWD cars among the inspirations listed, I’m expecting all three drivetrain types to be viable.
