As Thursday's test session in Valencia came to a close, it was Lotus-Renault's Robert Kubica who stole the headlines.
The Pole acheived an unofficial time of just over 1 minute 13, which was the fastest lap of anyone over the three testing days.
The next quickest 2011 cars were Mark Webber for Red Bull, Felipe Massa for Ferrari, Pastor Maldonado for Williams and Sergio Perez for Sauber. However, the 2010 cars of Adrian Sutil's Force India, Jenson Button's McLaren and Timo Glock's Virgin filtered inbetween.
Testing will commence again later in the month at Jerez, except for Team Lotus who will continue testing tomorrow after missing Tuesday's session.
