The final pre-season test ahead of the new F1 season gets underway today, with a further four days of running planned at the Circuit de Catalunya near Barcelona.
The test will be vital for teams as preparations go on for the 2013 opener in Australia, although the weather could work against them with rain forecast for the area. Indeed, the circuit is already wet for the opening day of testing, where the likes of Mark Webber, Felipe Massa and Lewis Hamilton will be in action for their respective teams.
Barcelona test line-up - Thursday 28 February:
Australia Red Bull-Renault
Paul di Resta
Britain Force India-Mercedes
France Toro Rosso-Ferrari
