The Potomac Stultus is a vehicle in Just Cause Unity .
It is a muscle car with a large V8, it is based off of the Pontiac Firebird Trans Am . It has suffered from a translation error at the boards in Potomac, as it was meant to be called the Impudens, meaning cool, but ended up being called Stultus: Fool.
Horribly slow, noisy and has to go about a kilometre an hour around corners. It still looks cool while doing it and activates your inner 11-year old.
