Luca Filippi marked his return to AutoGP by setting an emphatic early benchmark in the first practice session at Valencia.
The Italian missed the last round in Germany due to GP2 commitments, losing his lead in the points standings as a consequence.
The Super Nova driver made the best possible start to on his return weekend - AutoGP's penultimate round of 2011 - as he finished almost half a second clear of the rest of the field.
Lazarus' Fabrizio Crestani led the response, his 1m24.610s effort enough for second but 0.440s shy of Filippi's outright best.
At his home circuit Adrian Campos Jr was third fastest, ahead of one of Filippi's main title rivals Sergey Afanasiev.
Like Filippi, Afanasiev has missed one round - due to visa problems he could not travel to Donington Park - but a win and a second last time out put him back in contention. He was fourth fastest, just under 0.7s behind Filippi.
Campos Racing duo Adrien Tambay and Adam Carroll were split by just 0.018s in fifth and sixth respectively, ahead of current championship leader Kevin Ceccon of Ombra Racing.
Ceccon did just enough to steal the series lead in Germany, but his current two-point advantage over Filippi will be looking even slimmer after he finished more than 0.8s slower than the Italian.
DAMS driver Rio Haryanto edged out Durango's Giovanni Venturini for eighth, but the pair were both more than 1s off the overall best. Lazarus' Fabio Onidi rounded out the top 10.
