The car made extensive use of the composite materials Kevlar and carbon fibre to save weight and add strength.
The car also featured a new Martini colour-scheme, replacing the S4's white bodywork with red-based scheme.
The restored ECV1, rebuilt from the original parts, was displayed at the Rally-Legend Event on 7-8-9 October 2010 in San-Marino, by the owner, Giuseppe Volta.
