Casting reference

HW Prototype 12

HW Prototype 12 is a depiction of a high-performance, mid-engine track-focused supercar with a large wing and transparent side strakes. The model bears a resemblance to the McLaren F1 GTR. This model features heavily in the game Velocity X, released the same year as it's debut. Along with being the fastest car in that game, it is depicted as possessing highly experimental technology; not the least of which is a nuclear-powered cloaking device (and time machine).
