After the high-profile arrival and departures of Bobby Rahal and Niki Lauda, new managing director David Pitchforth gets time from the owners at Ford to build upon a solid 2003.

"We’ve had the same management structure in place for a season now and I believe that having stability and a good team structure is the key to being successful," said Pitchforth on launch day.

"Everybody involved with the team both in Milton Keynes and Northampton have done a fantastic job of getting the car finished on schedule.

"Unlike previous Jaguar Racing F1 cars, the new R5 was finished by the middle of December 2003. But it didn’t actually turn a wheel until mid-January, which gave us a whole month to test the systems before it ever went out on the circuit."

That should be good news for drivers Webber and new boy Klien who replaces the rather unlucky Justin Wilson.

Wilson had taken over from Antonio Pizzonia just before the German Grand Prix but failed to match the pace of team-mate Webber whose three sixth places were the highlights of the season.

Last season Jaguar had to wait until San Marino to get one car to the end of the race.

So, having got the R5 ready ahead of schedule, Jaguar will be looking for Aussie Webber to provide the grit to lead the team closer to the top six teams.
