High Quality Content by WIKIPEDIA articles! The 2006 Formula 3 Euro Series season was the fourth championship year of Europe’s premier Formula Three series. As in previous years, there were ten rounds – each with two races – held at a variety of European circuits. Each weekend consisted of one 60-minute practice session and one qualifying session, followed by one c.110 km race and one c.80 km race. In a revised qualifying system that used only one session, the starting order for race 2 was determined by the finishing order of race 1, with the top eight positions reversed.
