GP3 enters its second generation this weekend, as the fourth year of the championship kicks off as a support act to the Spanish Grand Prix.
The series has undergone big changes for 2013, with an updated car, a new engine, a revamped calendar and two new teams. Ocean Racing Technology and Atech CRS are gone, with Koiranen GP and Bamboo-Engineering respectively taking over their entries.
The new-spec car looks quite different to its predecessor in a deliberate attempt to make its appearance closer to that of big brother GP2. But those changes are mainly cosmetic, with new bodywork and aerodynamics bolted onto the original Dallara-built chassis that has been used since GP3 started in 2010.
