FERRARI
Michael Schumacher (Ger)
Age: 35
Wins: 70
Races: 194
Poles: 55
First GP: 1991 - Spa
You don't have to be a rocket scientist to predict that Schumacher has a record seventh title firmly in his sights. Hot favourite for another rich harvest.
Rubens Barrichello (Bra)
Age: 31
Wins: 7
Races: 178
Poles: 9
First GP: 1993 - Kyalami
In his fifth season with the red arrows, the popular Brazilian will be keen to avoid playing servant to master 'Schumi'.
WILLIAMS
Juan-Pablo Montoya (Col)
Age: 28
Wins: 3
Races: 50
Poles: 11
First GP: 2001 - Melbourne
Aggressive and ambitious, the Bogota-born 28-year-old would dearly love to be the one to ruffle king Michael's feathers - but can he keep his fiery Latin temperament in check?
Ralf Schumacher (Ger)
Age: 28
Wins: 6
Races: 116
Poles: 4
<
First GP: 1997 - Melbourne
Schumi's younger brother had a so-so 2003. Leaving filial affection firmly in the pits he'll be trying his hardest to close the yawning gap on Ferrari.
MCLAREN
David Coulthard
(Gbr)Age: 32
Wins: 13
Races: 157
Poles: 12
First GP: 1994 - Barcelona
Although the McLaren team has done plenty of close-season testing, both drivers are complaining about a shortage of power. Will Coulthard be able to make any impression in his last year for the team?
Kimi Raikkonen (Fin)
Age: 24
Wins: 1
Races: 50
Poles: 2
First GP: 2001 - Melbourne
One of the big finds of F1, Kimi Raikkonen has the ability to beat Michael Schumacher. However there are big question marks around whether his team will allow him to do so - by all accounts the latest car just isn't up to scratch.
RENAULT
Jarno Trulli (Ita)
Age: 29
Wins: 0
Races: 111
Poles: 0
First GP: 1997 - Melbourne
Until now Trulli has proved to be very quick in practice, but lacking the killer instinct necessary to take him to the front. This year he has a great car - and a great team-mate who last year showed him what winning is all about.
Fernando Alonso (Spa)
Age: 22
Wins: 1
Races: 17
Poles: 2
First GP: 2001 - Melbourne
Fernando Alonso knows what it's like to be a world champion - he's a former World Karting champion. And he proved last year that has the talent to challenge the best of the best.
JORDAN
Nick Heidfeld (Ger)
Age: 26
Wins: 0
Races: 66
Poles: 0
First GP: 2000 - Melbourne
A talented driver, but a shortage of funds at cash-strapped Jordan won't help his realise his full potential this year.
Giorgio Pantano (It)
Age: 25
Wins: 0
Races: 0
Poles: 0
First GP: 2004 - Melbourne
Pantano has looked impressive in his three seasons of Formula 3000. The Italian is undoubtedly with the team because of the amount of funding he could bring, but he'll be out to prove that he deserves his place in the sport's top flight.
BAR
Jenson Button (Gbr)
Age: 24
Wins: 0
Races: 65
Poles: 0
First GP: 2000 - Melbourne
Bursting with natural talent but has yet to climb the podium after four seasons. With the demise of Villeneuve the mantle of team leader falls on his young shoulders.
Takumi Sato (Gbr)
Age: 27
Wins: 0
Races: 18
Poles: 0
First GP: 2002 - Melbourne
Honda's favourite son will again be given the chance to prove himself as a race driver in 2004 following his year on the sidelines. He faces the task of shaking off the tag of "fast but erratic" off that has plagued him since his debut in 2002.
JAGUAR
Mark Webber (Aus)
Age: 27
Wins: 0
Races: 32
Poles: 0
Podiums: 0
First GP: 2002 - Melbourne
Mar Webber was a revelation last season, scoring 17 or the team's 18 points. However it will be interesting to see if Jaguar has the legs in 2004 to keep up with the other "lesser" teams.
Christian Klien (Au)
Age: 21
Wins: 0
Points: 0
Races: 0
Poles: 0
Podiums: 0
First GP: 2004 - Melbourne
This will be a big season for Christian Klien. He will be very aware that other highly promising rookies taken on by the team have not been given time to shine - but he comes with a reputed 6-million dollars backing from Red Bull.
MINARDI
Gianmaria Bruni(It)
Age: 22
Wins: 0
Races: 0
Poles: 0
First GP: 2004 - Melbourne
Minardi boss Paul Stoddart was pleased with "Gimmi's" contribution to the package last season as Minardi's test driver, and believes he has unearthed another genuine star in the making.
Zsolt Baumgartner(Hu)
Age: 23
Wins: 0
Races: 2
Poles: 0
First GP: 2003 - Hungary
He was successful in Formula 3000 and managed a creditable 11th place last year in his first season, but Baumgartner has a long road ahead of him with Minardi - mainly because it's the least competitive outfit around.
SAUBER
Felipe Massa(Bra)
Age: 22
Wins: 1
Races: 16
Poles: 0
First GP: 2002 - Australia
This season will be a second opportunity for Felipe Massa after struggling during his first spell in F1 in 2002. Sauber has kept faith with the driver they saw as their successor to Kimi Raikkonen.
Giancarlo Fisichella (Ita)
Age: 31
Wins: 1
Races: 123
Poles: 1
Podiums: 9
First GP: 1996 - Melbourne
With a lucky win up his sleeve in Brazil from last year, Fisichella will be keen to impress this season with a jon at Williams up for grabs.
TOYOTA
Olivier Panis (Fra)
Age: 37
Wins : 1
Races: 141
Poles: 0
First GP: 1994 - Interlagos
Although he's the oldest driver in Formula 1, this veteran Frenchman brings an assured touch to the fledgling Japanese outfit. Toyota is the team of the future - but not 2004.
Cristiano Da Matta (Bra)
Age: 30
Wins: 0
Races: 16
Poles: 0
First GP: 2003 - Melbourne
Da Matta came in a ball of glory last year after sweeping all before him in the US CART series for the Toyota-backed Newman-Haas team, but so far hasn't managed to crack anything special in F1..
