The GT020 is a developmental car and was fitted with a developmental engine, perhaps a Supersport block in US specifications. The interior of the car is a GT one with a custom set of pedals, and dashboard wood plates replaced by carbon ones. The lateral side windows were replaced by Supersport holes plate and the car was fitted with SS rims. The GT020 has been introduced as a genuine Supersport model, first by the London dealer Pullicino's Classics and then by the successive owners (Verdi in UK, Elite Garage in Switzerland). The car was tested at Auto Italia in July of 1997, as a Supersport model, versus a Ferrari F40.
