|The final pre-season testing before the start of the 2013 GP2 Series began on Tuesday with the Circuit de Catalunya beset with heavy rain and strong winds. Most of the teams opted to wait until the weather improved before setting any lap times and, not surprisingly given the conditions, once the cars took to the track the session was interrupted by several red flags. Both of the Racing Engineering drivers managed over 20 laps each as they set up their cars for the wet conditions and Fabio Leimer finished the session in 4th with a fastest lap of 1:52.316s, his teammate Julián Leal finishing right behind him in 5th with a best time of 1:52.334s.
The weather had improved for the afternoon session, although the track was still damp at the start, but lap times soon began to fall as the track dried out. Fabio was once again amongst the fastest runners finishing 6th after setting a time of 1:30.335s after 16 laps. Julián was just over a second slower as he continued to set up the car to his liking, finishing with a time over 1:31.520s.
The weather for both of the Wednesday sessions proved to be equally uninviting with more rain and low temperatures. Once again wet weather tyres were required and Fabio and Julián both completing 26 laps in a morning session delayed by two red flags. Fabio’s best time was 1:52.594s with Julián less than half a second slower on 1:52.946s.The afternoon session saw Julián right on the pace setting a best lap of 1:53.524s after 37 laps to be 8th quickest, less than 0.8 seconds behind the fastest lap. Fabio completed 22 laps for the 11th fastest time on 1:53.920s. Once again three red flags disrupted the session.
