2010 MotoGP world champion Jorge Lorenzo is to drive a GP2 car for the Addax Team at Valencia today.
“Good morning guys! Today I'll drive a GP2 in Cheste,” Lorenzo wrote on his Twitter page.
GP2 is the feeder series for F1 and features single-seater racers powered by 4-litre V8 engines. They have a maximum speed of 332 km/h.
Formed in 2005, present F1 drivers Lewis Hamilton, Nico Rosberg, Romain Grosjean, Sergio Perez, Pastor Maldonado and Charles Pic all passed through the GP2 Series.
Addax is the reigning GP2 teams' champion.
Lorenzo, runner-up to Honda's Casey Stoner last season, will be back on two-wheels when he tests his Factory Yamaha during the final pre-season outing at Jerez, which starts on March 23.
