Design and Construction of a Lightweight GT Prototype

A lightweight sports car prototype named “PT 97 A Promise” was built by the Scuderia Bizzarrini Co. at the beginning of 1997 in Livorno, Italy.

The “PT 97 A” was developed for the purpose of achieving very high performance on normal roads through lightweight construction.

This paper describes the main features of the car and a computer model for predicting vehicle performance during track tests. A performance simulation of the “PT 97 A” on the race track of Fiorano is also presented, along with other data.
