Felipe Massa failed to make the final phase of qualifying at a grand prix for the second race in a row after being unable to improve on his initial flying lap time on a final run at the Chinese Grand Prix.
The Brazilian will start from 13th on the grid at the Shanghai International Circuit after lapping nearly a full second from pacesetter Sebastian Vettel. Ferrari team-mate Kimi Raikkonen made it through to the final phase in ninth spot in the KERS-free F60, but only by a tenth of a second.
Massa will have some high-profile company in places 11-15 as Nick Heidfeld, Heikki Kovalainen - not using McLaren's new front wing after a negative evaluation on Friday but badly baulked by traffic - Timo Glock and Kazuki Nakajima also fell in Q2. Glock will now start 19th after suffering a gearbox problem that necessitated a change during Saturday morning practice.
Vettel appeared set for an early exit after sitting in the Red Bull garage for all bar the last three minutes of the session, but responded in style by posting the fastest lap of the 15 minutes, setting the benchmark at 1min 35.130 as the RB5s headed the table from the two Brawn GP runners.
Lewis Hamilton - on course for a first top ten start of the year with the revised McLaren - Fernando Alonso, Nico Rosberg, Raikkonen and surprise package Sebastien Buemi will also contest the top ten shootout.
