Alain Menu will start the first World Touring Car race of the weekend at Estoril from last position after he failed technical scrutineering following qualifying.
'Dovi' was the first to go, the MotoGP rookie having previously ridden a brilliant race to keep his satellite Honda in close contact with the race leaders for the first 15 laps.
Lorenzo passed both Repsol Honda star Pedrosa and his illustrious Fiat Yamaha team-mate Rossi to take the lead for the final time on lap 13, but Pedrosa couldn't get around Rossi's Bridgestone-shod M1 for a further two laps - by which time Jorge was just out of reach.
Corsi was involved in a race-long battle with Belson Derbi's Joan Olive, as those involved in the tussle for the win gradually dropped out of the running.
The Spaniard, who suffered a mechanical failure while leading on the last lap of his home Jerez race and was hit from behind by Marco Simoncelli - bringing them both down - blasted past pole sitter Simoncelli along the back straight during the opening lap, then rode into the distance.
