3000 Pro Series 2005

2005 was the only season run under the name 3000 Pro Series. All cars were identical: a Lola B99/50 with a Zytek engine. Over eight races between Vallelunga and Monza, 27 drivers from eleven teams took part. In 2006 the series continued as the F.3000 International Masters.

Timo Lienemann won the opener at Vallelunga, while the two later title rivals both retired from the front row. From then on Norbert Siedler (ADM Motorsport) and Max Busnelli (PRO Motorsport) set the pace. Siedler won at Imola and Spa-Francorchamps, each time ahead of Busnelli, and at Mugello the order was reversed. At Misano Busnelli retired from pole, while Siedler finished second behind Alessandro Bonetti. Robbie Kerr then won at Lausitz and Lienemann took Adria. Siedler led with 41 points going into the final round. Busnelli had 39, Lienemann 35 and Bonetti 34, so four drivers could still mathematically take the title.

At the Monza finale on 9 October, Busnelli won by 0.2 seconds from Siedler. That left both on 49 points, with two wins, three second places and one fourth place each. The title was decided by a result that scored nothing: Busnelli had retired at Misano, but he had covered enough laps to be classified tenth. Neither of Siedler's two retirements was classified.

ADM Motorsport argued that once the points finishes were level, pole positions should have decided it. Siedler had five, Busnelli two. On 11 October 2005 the organiser, Peroni Promotion, confirmed Busnelli as champion. It cited Article 27 of the sporting regulations and the rules of the Italian governing body CSAI: in a tie on points, only finishing positions count, first the wins, then the second places and so on.

Lienemann finished third overall with two wins and 41 points. Bonetti was fourth on 39 points and scored in seven of the eight races. Thanks to Lienemann and Bonetti, Draco Racing won the teams' championship with 80 points, ahead of ADM Motorsport (69) and PRO Motorsport (61).
