Race drivers Jarno Trulli and Timo Glock were behind the wheel on a hot and sunny day in the Middle East to resume the team's programme of set-up development. The warm weather ... gave the team another chance to monitor the cooling characteristics of the TF108, which features a revised cooling lay-out. As well as looking at different mechanical set-ups, aerodynamic work was also carried out and some development items evaluated while practice pit stops took place after the day's running had ended in preparation for a Grand Prix simulation tomorrow. Another trouble-free day saw Jarno and Timo complete their full programmes, gathering useful set-up information, and both drivers will continue preparations for the new season tomorrow.
