Jorge Lorenzo set the pace in a crash-strewn first MotoGP practice session at the Sachsenring.
The Spaniard, competing just a fortnight after breaking his collarbone at Assen, hit the front halfway through the session and was then able to continually improve his pace to ensure he was never displaced.
Both championship leader Dani Pedrosa, chasing a fourth straight MotoGP win at the German track, and Valentino Rossi, winner last time out at Assen, were able to close to within one tenth of Lorenzo in the final minutes.
As the chequered flag fell however, the reigning champion upped his pace once more, setting a 1m22.047s to go nearly two tenths clear at the front.
Behind Pedrosa and Rossi, Marc Marquez beat satellite riders Stefan Bradl and Cal Crutchlow to fourth.
The latter contributed to the list of severe crashes when he fell and bounced heavily through the gravel at Turn 1.
Andrea Dovizioso had been the first to fall when he lost his Ducati at the sixth-gear Turn 11 'waterfall'. He was able to walk away, although his bike was badly damaged.
It was even worse for Andrea Iannone, whose Pramac Ducati was totalled - with the entire rear section falling away - when he too crashed in the same section.
Nicky Hayden on the second works machine also suffered a gigantic tank slapper exiting Turn 10, although he somehow managed to hold on.
The American ended the session in eighth, just behind Aleix Espagaro, who again impressed on his Aspar Aprilia.
Alvaro Bautista crept into ninth late on, with a returning Dovizioso rounding out the top 10.
