[1] The championship started in 2005 as the 3000 Pro Series, organised by Peroni Promotion and based in Italy; it used Lola B99/50 chassis alongside 2002 cars.

As with previous seasons, the series was to support the World Touring Car Championship, consisting of seven double-header events beginning on 22 May at Autodromo Nazionale Monza in Italy and ending on 19 September at the Circuit de Valencia.

Nico Müller and Philip Forsman were the fastest drivers on each day, which would ultimately prove to be the last outings for an IFM car.

Notable venues used included Pau in France, Brands Hatch in Britain, Brno in the Czech Republic, Porto in Portugal, and Monza in Italy.

During the International Formula Master years, the series supported the World Touring Car Championship for its European events.
