If Nick Heidfeld needed to proove he had the ability to replace the injured Robert Kubica for Lotus-Renault, then his performance today will certainly go someway towards that.

Unofficial timing puts Schumacher in third, Hamilton fourth, Kobayashi fifth and Vettel sixth, but Schumacher is already looking towards future updates to improve the Mercedes' pace and has expressed concerns that the team still need to get more testing laps under their belt.
Promisingly for Team Lotus, Heikki Kovalainen's best lap was only 0.7 seconds off Schumacher's pace, which suggests some major steps forward have been acheived by the team.
