While there are no performance increases, the Spider Mille Miglia is based on the standard 3.2 V6 powerplant that outputs 260hp. Rather than performance upgrades, each special edition features a silver plate that outlines one of Alfa Romeo's victories between 1928 and 1947. The special edition Alfa also gets an exclusive, bright red paintjob called 'Rosso 8C' and a 'Quadrifoglio' logo (a four-leaf clover) on its front side, as well as red stitching for the black leather seats.
The Mille Miglia race has been run just 24 times in the period between 1927 and 1957 and was banned following a fatal crash in 1957 in which the driver, co-driver and 11 spectators were killed in an Italian village.
Today the race is run with commemorative cars from the 1927-57 period as a parade and is known as the 'most beautiful race in the world' amongst its fans.
