The GP3 Series, or GP3 for short, was a single seater motor racing series launched in 2010 as a feeder series for the GP2 Series, introduced by GP2 organiser Bruno Michel.
GP3 followed the entire European leg of the Formula One series and the GP2 (now Formula 2) series as a support race for the two. In 2012, the series visited the Monaco street circuit after 2 years of attempts, as they were always unable to beforehand due to lack of room. Like the GP2 series, GP3 gave drivers the experience of the Grand Prix environment, and took advantage of the infrastructure, such as marshals and medical facilities, in place for the Formula One events. GP3 Series mainly raced on European circuits, but had appearances on other international race tracks as well with their most recent races in the only 2015 season at the Bahrain International Circuit in Bahrain and the Yas Marina Circuit in United Arab Emirates since 2010 season. The series were planning for more international races such as Albert Park, Austin, Interlagos, Marina Bay, Mexico City, Montreal, Shanghai and Suzuka.
For the 2010–2012 seasons, the GP3 series used the GP3/10 chassis.
The car had been designed and built by Dallara, who currently produces the GP2 chassis.
The GP3/10 used a four-cylinder 2.0-litre turbocharged 280 hp engine developed by Renault Sport, while turbochargers were supplied by Pankl Racing Systems. The wastegate was included due to turbocharger rules.
The GP3/10 used a 6 speed longitudinal sequential Hewland gearbox.
Pirelli supplied the tyres for GP3 from 2010 to 2012, same supplier for the GP2 Series.
