Pre-Hungarian GP update: team by team.

All the F1 teams may have been on holiday these last three weeks but that doesn't mean to say nothing's been happening. Find out what has been going on behind the scenes in the build up to the final five F1 races of the year:

Ferrari - Badoer at Fiorano:

The shakedown of the three F2001 chassis designated for the Hungarian Grand Prix was carried out by Luca Badoer this week and last and the Italian also did some practice starts. Michael Schumacher, meanwhile, spent the time since the German Grand Prix with his family in Switzerland and also carried on with his usual training programme.

On Monday Badoer shook down two of the cars and shook down the third one on Tuesday. The team will use chassis 206 for Barrichello, 210 for Schumacher and 211 as the spare in Hungary. The latter's fuel system has been completely renewed since the problem that caused Michael's retirement in the German Grand Prix. The Ferraris will also use an aerodynamic evolution of the package they used at Monaco and the engines have also been further developed.

McLaren-Mercedes - Back at the factory:

The McLaren-Mercedes used at least part of the three week break since Hockenheim analysing the causes of the engine failures which sidelined Mika Hakkinen and David Coulthard from the German Grand Prix. "These were identified as oil pump drive failures caused by a manufacturing fault," said McLaren International Managing Director Martin Whitmarsh. Most of the workforce had a long weekend off in the middle of the break before work began on preparing the trio of MP4/16s for this weekend's race. The team also started concentrating seriously on the configuration of next year's car during this extended gap between races.

Williams-BMW - No major changes:

Most of the team personnel have been working flat-out at BMW-Williams since the German Grand Prix, but the team denies that there are major revisions to the FW23 in the immediate development pipeline. "We've got nothing special at all for Hungaroring," said a team spokesman this week, "other than efforts to optimise the car for a circuit which might not be so user friendly towards us as some others on the calendar." Ralf Schumacher used the break for holidays, both at his new home in Salzburg and in Mallorca.

Sauber-Petronas - No shakedown:

Most of the Sauber team used the break for a holiday. The team will also go to Hungary without having undertaken a shakedown. "It does not justify the cost, as we would have to travel quite some way to find a circuit for that," said Technical Director Willy Rampf. The C20s will have a completely new high downforce package in Hungary, including a new floor and rear wing. "This is the result of what we learned at Monaco," said Rampf.

BAR-Honda - Feeling upbeat:

The team left Hockenheim on a massive high after Jacques Villeneuve's podium finish and the whole team was given a full week off by the management to help them recharge their batteries for the last five races of the season. BAR-Honda is confident that a new aerodynamic package will improve their performance at the low speed Hungaroring and in recent testing at Valencia the team concentrated in anticipating the problems which might be experienced in Hungary. As a result of those tests, a number of aerodynamic improvements have been made and the team hopes to see an improvement following the difficulties experienced at Monaco.

Jordan-Honda - Alesi has his first run in the EJ11:

Major behind-the-scenes changes at Jordan occured during the three week break as negotiations for Jean Alesi's race debut for the team were finalised over the last ten days. The 37-year old Frenchman had his first run in a Jordan-Honda EJ11 at Silverstone on Monday 13 August (within the prescribed shakedown limits which impose a maximum of 50 miles).

Benetton-Renault - New aero package:

The Benetton-Renault squad is determined to build on its promising Hockenheim result, where Giancarlo Fisichella and Jenson Button took fourth and fifth places, and to that end the B201s will be fitted with a heavily revised aerodynamic package in Hungary. "This is a substantial aero update centre round a totally new front wing," said Technical Director Mike Gascoyne who confirmed that the package of modifications would be checked out at a Silverstone shakedown today (Thursday).

Jaguar-Racing - High hopes for Hungary:

Jaguar Racing spent the break preparing for Hungaroring, which the team believes should offer its best chance of finishing in the points since Monaco. "High downforce tracks are the best for us," said a Jaguar Racing spokesperson. "Our car doesn't seem to like really high speed corners, which will make Spa and Suzuka in particular quite difficult for us." With the test ban in force since Hockenheim, the team's running has been confined to the Silverstone pit lane where last week Jaguar Racing was making a documentary on refuelling stops on behalf of Texaco, their fuel sponsor.

Prost-Acer - Frentzen tries the AP04:

Heinz-Harald Frentzen tried the Prost AP04 at Magny Cours last Friday where, in order to remain under the 50km limit, the team combined both the Grand Prix circuit and the school circuit. Frentzen had to cope with a new car, new engine, new tyres and different controls on the steering wheel, but at the end of the trouble-free test he began applying minor changes to the set-up. During the three week break Prost has rebuilt the car which Luciano Burti crashed at Hockenheim and will use an evolution of its high downforce aero package this weekend.

Arrows-Asiatech - New front wing:

The Orange Arrows-Asiatechs will have new front wings for the Hungaroring which should help them in their quest for optimum handling on this high downforce circuit, an environment which Jos Verstappen believes has not suited their cars so far this season. Technical Director Mike Coughlan said: "The Hungaroring may not suit our car as well as other circuits. It is like Monaco in that it is a particularly high downforce track with a lot of tight turns, but we have a new front wing which should give us some advantage."

Minardi-European - At Fiorano:

The European Minardi team has completely overhauled its three chassis and the team tested at Fiorano last week with Andrea Piccini using the shakedown to evaluate the new titanium gearbox and revised rear suspension. Alonso will again use it for first practice in Hungary and, if it is satisfactory, there are sufficient parts available to convert Marques's car.
