The model on show, destined for mass production, is the Delta Integrale Evoluzione, produced from 1991 to 1993, with a 16-valve engine, a Martini livery (used in competitions), and many aesthetic touches such as enlarged track widths, side curves, different bumpers and mechanical improvements (to the suspension, brakes, steering box and electronics). The price was appropriate for the performance levels: about 45 million lire.
