Formula 1 teams finished their pre-season testing on Sunday and are now packing their cars away to send them to Bahrain for the first race of the season in less than two weeks' time.

After four days pounding around the Circuit de Catalunya, a picture has emerged about the relative competitiveness of the cars.

Leaving Barcelona, the top four teams look closely matched, although Red Bull and Ferrari are probably slightly ahead of Mercedes and McLaren. Either way, F1 looks poised for an intensely competitive season.

We analyse the teams in pit-lane order.

MERCEDES

There's a walkway on the first floor of the Barcelona pit building where one can see straight into the Mercedes GP engineering office. Security guards move people on during the day, but as evening falls they go home, allowing a perfect view of Michael Schumacher at work.

He sits on the edge of a chair, leaning forward on the desk, engaging an engineer in an intense discussion about some minute detail of the car's performance. He's as focused and business-like as he always was, and he needs to be: the Mercedes has not been the quickest car in testing.

Schumacher gave mixed messages about his car's pace in Spain

It's impossible to know precisely who is fastest, not only because they are running differing fuel loads, but because they are doing that on different tyres (medium, soft and super-soft were all being used in Barcelona) at different times of the day in different track and weather conditions.

But the teams have engineers who analyse their rivals' lap times, working backwards from known fuel quantities (at the start of a race simulation, for example), so that's how we have a general picture of how fast the cars are. The Mercedes seems to be tied with the McLaren as third quickest car behind Red Bull and Ferrari.

Schumacher has seen that analysis and says he isn't too worried about Mercedes' shortcomings, but he won't see the true pace of the car until Friday in Bahrain, when the team run with their new wings and diffuser.

As the single largest generator of downforce on the car, the diffuser is a big thing to bring to a track for the first time, bolt on and make work, so the team face a challenge to balance out the car in practice at the first race of the season.

This promised development puts Schumacher's recent statements about Mercedes not being in a position to win races straight away into context.

RED BULL

Webber positive ahead of first race

Confident in their car's speed, Red Bull pack up for Bahrain looking to be at the front straight away.

Team boss Christian Horner believes the RB6 will be "up there with Ferrari" and is happy with the new front wing, bargeboards and rear wing brought to the last two days of the Barcelona test.

The Red Bull's diffuser is a beautifully intricate bit of kit, similar in appearance to the one on last year's Brawn, with a big lemon-shaped hole in the middle section and Toyota-style vanes either side.

Chief technical officer Adrian Newey has also proved innovator with his treatment of the exhaust pipes.

As this picture shows (right), the exhaust vents to the outer side of the gearbox below the bottom suspension wishbone, channelling the hot air around the rear suspension and out the top side of the floor.

The disadvantage is that the suspension will get quite hot from the exhaust gases, so the team placed blue temperature sensors on the wishbones and the floor during testing to find out if it's too marginal to use.

In a comical and ultimately futile attempt to mislead rival teams and the watching media, the picture also shows that Red Bull placed a sticker of an exhaust pipe on the upper bodywork below the upper wishbone, where one would expect to see it!

As well as that clever chassis, a fuel efficient Renault engine and good tyre performance in qualifying trim mean that the Red Bull is many people's tip for the championship.

One downside: reliability. Precautionary changes to gearboxes and oil pumps interrupted Red Bull's Saturday programme in Barcelona, leading to Mark Webber having to surrender half his allotted time in the car on Sunday to Sebastian Vettel, much to the Australian's annoyance.

McLAREN

McLaren had their Bahrain aerodynamic package on for the last two days of the test and the car enjoyed a significant improvement.

Hamilton happy with McLaren progress

The updates delivered what the wind tunnel suggested they would, which is always a relief for any team with a new car.

Jenson Button ran a race simulation with the new package on Saturday but did not have the set-up he wanted on the car, so his times didn't compare too well with Ferrari's Felipe Massa, who was also doing a race run at the same time, or his McLaren team-mate Lewis Hamilton, who did a race simulation on Sunday.

McLaren engineers have been investing a lot of time in tyre management - a key component this year as most races will be done on a one-stop strategy following the banning of in-race refuelling.

Success in the first few races will come from being easy on the tyres and keeping them in good shape. In short, McLaren are not where they want to be yet, but they're close and they believe they'll get there.

FERRARI

It's simple to explain why Ferrari have a good car. They've been working on it full-time since June last year while everyone else was still bringing performance to their 2009 cars.

Alonso optimistic over title chances

Crucially, this year the design has not been compromised by having to integrate last year's Kers power-boost system on the car. They have also exploited the double-diffuser concept to the full.

The result is a driveable car that was quick out of the box, has good reliability (although there were small niggles throughout the Barcelona test) and is consistently easy on its tyres.

Ferrari fly to the first race perhaps the best prepared of anyone. Among the first to launch their car, they made good use of the sunny weather at the first test and have managed to complete their job list in preparation for Bahrain. Both drivers have completed race simulations successfully.

The only surprise might come in the improvements other teams bring to the first race. Ferrari have shown their hand: The package they had on the last two days in Barcelona is pretty much how the car will race in Bahrain. Will the rest catch up?

THE MIDFIELD

The dark horse of the midfield is Force India. Adrian Sutil described this winter as "the best pre-season test programme we've ever had".

In retrospect they lost out by missing the first test as the recent poor weather hasn't allowed as much meaningful practice as they'd like, but the car is predictable, driveable and consistent on high and low fuel.

Williams are also happy with their package, with reports of good power and fuel efficiency from their Cosworth engine.

Veteran Rubens Barrichello has integrated seamlessly into the team following his move from Brawn and looks like he's been there for years.

Rookie Nico Hulkenberg has impressed technical director Sam Michael with his speed in testing.

"We want Nico to show a clear rate of progression and to push Rubens while making as few mistakes as possible", says Michael, which is what they wanted - but never got - from Kazuki Nakajima over the last two years alongside Nico Rosberg.

Sauber continue to impress with their qualifying pace.

Kamui Kobayashi was equal to the Williams and Force India on lower fuel, but he admitted that the team need to work on tyre management on heavy fuel loads. Money may also be a factor later in the season - at present the car boasts very few sponsor logos.



In many ways, Renault have the most nervous wait to see where they are in the pecking order. Robert Kubica says the car lacks grip and the lap times back him up.

The team have a package of aerodynamic and mechanical improvements coming for the first race. The wind tunnel suggests they will be a big step, while Kubica is keen to see if they translate to improved lap time.

Gascoyne aiming for Lotus reliability

Rookie Vitaly Petrov faces a tough start to the season, but is lucky to have a new, experienced engineer to look after him: Mark Slade, who won races and championships with Mika Hakkinen, Kimi Raikkonen and Heikki Kovalainen, has moved from McLaren to Renault.

The Toro Rosso STR5 looks very similar to the Red Bull RB6 even though Toro Rosso have had to design and make the car themselves in Faenza. The team say the car is sound enough, but Sebastian Buemi spent most of the test trying different set-ups in an attempt to unlock some more speed from the Ferrari-engined car.

NEW TEAMS

Lotus ended the Barcelona test five seconds slower than the pace-setting McLaren. This is the margin they will have to live with for the first few races.

The car is more reliable than that of fellow new boys Virgin, although not entirely bulletproof. The team have a significant aero package coming onto the car at the Spanish GP in May, so we can begin to judge their long-term potential then.


The Virgin seems to be faster than the Lotus over one lap but the car is fragile.

Technical director Nick Wirth admits that there has been a design error on some parts of the hydraulic system. As pretty much everything that makes you stop or go in an F1 car is hydraulically-driven (throttle, gearbox, brakes), it's important to have it indestructible.

Wirth says there will be a fix in place for the first four races while a re-design continues back in the UK. There's an improved aero package that will add performance to the car in Bahrain.

Jerez testing week two review

After another wet-dry week of testing at Jerez, itv.com/f1 summarises each team's position heading towards the final few days of pre-season running.

We've also compiled the full stats from the winter so far to show which teams are looking swift and which are struggling after three weeks of 2010 preparations.


McLaren
Driver schedule: Weds/Thurs - Hamilton, Fri/Sat - Button
Best time: Button, 1m18.871s, Sat
Day by day results: (Weds to Sat) 2nd, 9th, 3rd, 1st
Total laps: 338

Jenson Button had the best of the weather this week, with Lewis Hamilton unable to get much done during his two days on a soggy track.

Last year's world champion thoroughly enjoyed Friday and Saturday, though, getting ever more comfortable in the McLaren and setting the best time of the winter at Jerez during a short run on Saturday morning.


Mercedes GP
Driver schedule: Weds/Fri - Schumacher, Thurs/Sat - Rosberg
Best time: Rosberg, 1m20.061s, Sat
Day by day results: 6th, 4th, 5th, 5th
Total laps: 391

Longer runs were the plan for Mercedes this week, at least once the rain cleared.

Both Michael Schumacher and Nico Rosberg left Jerez satisfied, having covered plenty of mileage, set promising times throughout their stints, and encountered no problems.


Red Bull
Driver schedule: Weds/Thurs - Vettel, Fri/Sat - Webber
Best time: Webber, 1m19.299s, Fri
Day by day results: 1st, 3rd, 1st, 8th
Total laps: 371

After its quiet start in the first Jerez test, Red Bull showed its hand this week and topped two of the four days.

Sebastian Vettel was stuck with a wet track for his two days, while Mark Webber enjoyed all the dry running.

Reliability remains a slight concern - both Webber's days were interrupted by problems, including an engine change on Saturday.


Ferrari
Driver schedule: Weds/Thurs - Massa, Fri/Sat - Alonso
Best time: 1m20.115s, Alonso, Fri
Day by day results: 3rd, 5th, 2nd, 6th
Total laps: 433

Week three of testing was all about long runs and gaining maximum mileage for Ferrari.

The team was thrilled with its reliability, and after once again setting relentlessly quick times on some very long runs, Fernando Alonso confidently declared the F10 the greatest car he had ever driven.


Williams
Driver schedule: Weds/Thurs - Barrichello, Fri/Sat - Hulkenberg
Best time: Hulkenberg, 1m21.432s, Fri
Day by day results: 10th, 1st, 4th, 9th
Total laps: 482

Lots and lots of laps for Williams, which focused on race simulations - including pit stop practice - for much of the week.

Times were reasonable rather than headline-grabbing, although Rubens Barrichello was quickest in the wet on Thursday, but both drivers also lost some time to gremlins.


Renault
Driver schedule: Weds/Thurs - Petrov, Fri/Sat - Kubica
Best time: Kubica, 1m19.114s, Sat
Day by day results: 9th, 2nd, 6th, 2nd
Total laps: 328

Vitaly Petrov was stuck with the wet weather again, but he did manage to complete a good number of laps - and impressed by going second quickest on Thursday.

Robert Kubica was also satisfied when he took over for the final two days, and was encouraged by both the car's pace and the obvious progress Renault was making.


Force India
Driver schedule: Weds - di Resta and Sutil, Thurs - di Resta and Liuzzi, Fri - Sutil, Sat - Liuzzi
Best time: Liuzzi, 1m19.650s, Sat
Day by day results: 7th/8th, 7th/9th, 7th, 4th
Total laps: 285

Test driver Paul di Resta joined Tonio Liuzzi and Adrian Sutil for the second test, and although all the Scot's mileage was on wet days, he still felt that was good experience for the future.

Force India again showed promising pace when it dried, but the two race drivers were keen to get more dry mileage in the final test to try and better understand this year's tyres after some graining issues.


Toro Rosso
Driver schedule: Weds/Thurs - Buemi, Fri/Sat - Alguersuari
Best time: Alguersuari, 1m21.053s, Sat
Day by day results: 4th, 11th, 8th, 7th
Total laps: 395

At Toro Rosso it was Sebastien Buemi who got all the wet weather, while Jaime Alguersuari enjoyed the dry days.

There were few spectacular times, but the team completed plenty of race practice and reliability work, and feels in good shape heading to the final test.


Virgin
Driver schedule: Weds/Thurs/Sat - Glock, Fri - di Grassi
Best time: Glock, 1m22.433s, Sat
Day by day results: 12th, 8th, 10th, 10th
Total laps: 144

Niggling hydraulic problems, and also a few excursions from the drivers, limited Virgin's running again in its second test.

The hydraulic issue could not be resolved at the circuit, so the team just had to press on and do what it could in the few laps it could manage - and despite its difficulties, it was respectably close to the pace.


Lotus
Driver schedule: Weds - Fauzy, Thurs/Fri - Kovalainen, Sat - Trulli
Best time: Trulli, 1m23.470s, Sat
Day by day results: 11th, 12th, 11th, 11th
Total laps: 315

Although Lotus did not set the timesheets alight on its first test, it completed a large number of laps - despite Heikki Kovalainen losing time with a few technical problems and a crash on his days.

The team wasn't trying to push for times this week either, instead focusing on acclimatisation work on heavy fuel and long stints, and is confident it has a great basis for progress when it does start showing its true potential.


Sauber
Driver schedule: Weds/Thurs - de la Rosa, Fri/Sat - Kobayashi
Best time: Kobayashi, 1m19.881s, Sat
Day by day results: 5th, 6th, 8th, 3rd
Total laps: 229

Pedro de la Rosa was desperate for some dry running after another wet day as testing began, and when Thursday dawned wet again, Sauber decided there was little point running at all, and spent most of the day in the pits.

A fuel system problem on Friday meant Kamui Kobayashi had a quiet day too, but he was still pleased with what he achieved when he did hit the track, and he underlined Sauber's form with a strong third place on Saturday.

Substitute drivers to get pre-race test

From next year, drivers joining a team mid-season may be eligible for a day’s testing prior to racing. In 2009 strict testing restrictions meant Toro Rosso’s Jaime Alguersuari made his Formula One race debut with no F1 experience outside of straight-line aero testing, while Michael Schumacher was unable to sample the current Ferrari ahead of his planned comeback.

Now, if a team declares that one of their current race drivers is to be substituted by a driver who has not participated in an F1 race in the two previous calendar years, one day of track testing will be permitted, on an approved circuit not being used for a Grand Prix in the current season.

In another minor change to the testing regulations, teams will be allowed six rather than eight days of straight-line aero testing per season. They will also have the option of substituting any of these days for four hours of wind tunnel testing with a full-scale (rather than the normal 60 percent-scale) model.
