Big week ahead in Barcelona 19 Jan 2004
This week sees 2004's busiest test session to date, with every Formula One team bar McLaren and Minardi expected at the Circuit de Catalunya in Barcelona. BAR and Jaguar have three-day programmes planned, while the remainder of the field will all be running for four or five days.
With the launch of their 2004 car less than a week away, Ferrari will be hard at work at the Spanish circuit. They will be joined by fellow Bridgestone runners Sauber, putting more miles on the new C23, and Jordan, for whom this week's test is likely to be the last for the outgoing EJ13.
Belgian driver Bas Leinders will be at the wheel of the 2003 Jordan on Wednesday, but the team has yet to announce who will be in the cockpit for the other three days of the session. Both Jordan race seats for 2004 remain unfilled, though a spokeswoman told the BBC last week that the team are in talks with Jos Verstappen and Nick Heidfeld.
Williams will continue development of their 2004 machine, the FW26, as well as giving a further test to Formula One hopeful Nico Rosberg in an FW25. Meanwhile, rivals Renault will debut their contender for this season's honours, the R24, ahead of its official launch in Palermo, Sicily on January 29.
Jaguar will get a chance to put some serious mileage on the new R5, following technical difficulties during its post-launch run-out at the circuit on Sunday. And for Toyota it will be the first time their new machine, the TF104, has appeared alongside its rivals after being unveiled in Cologne on Saturday.
Check back every day for updates on the teams' progress in Barcelona. All schedules are unofficial and subject to change.
