The Birusa is based on a BMW, as you can see at the front.
Birusa, a name coming from a word in Italian slang, standing for a brilliant, and resourceful person.
The chassis for the prototype was borrowed from a BMW Z8.
And so the Birusa follows a tradition, that started with the grandfather of the Z8, the BMW 502, followed by the 3200CS.
wheelbase: 285cm, extended (30cm) Z8-chassis
