GP2's tag as Formula 1's feeder series has been well earned. In the four years since it arrived on the motorsport landscape, the FOM-backed championship has delivered no less than seven drivers to F1.
The series can already boast to be Lewis Hamilton's last stop before becoming world champion, and as the 2009 line-ups take shape, over one third of the confirmed grid is made up of ex-GP2 drivers.
Nico Rosberg (Williams), Kazuki Nakajima (Williams), Timo Glock (Toyota), Sebastien Buemi (Toro Rosso), Nelson Piquet Jr (Renault), Heikki Kovalainen (McLaren) and Hamilton (McLaren) have all graduated straight from GP2 to F1.
But who's next? Here are five current GP2 drivers who have the potential to be F1's next bright young thing.
