Sebastian Hohenthal (S)
2008 season: 7th in British Formula 3
Finds refuge in F2 following under-par season of British F3 in 2008. Has one of the best records in the F2 field, having won the Formula Renault UK title in 2006 and an F3 race in each of the past two years.
Jolyon Palmer (GB)
2008 season: 3rd in Formula Palmer Audi
The son of series boss Jonathan Palmer is one of four Formula Palmer Audi graduates. He has won races in both of his years in single-seaters so far, but he's never yet faced the depth of talent he'll find this season.
Julien Jousse (F)
2008 season: FRenault 3.5 runner-up
Jousse took a long time to graduate from Formula Renault and didn't make much of an impression in his first FR3.5 season in 2007, but he raised his game last year as the closest rival to runaway FR3.5 champion Giedo van der Garde.
Alex Brundle (GB)
2008 season: 6th in Formula Palmer Audi
The son of former grand prix driver Martin Brundle improved steadily from initial wild reputation during his two seasons of FPA. He's still yet to win a single-seater race, though and will face a steep learning curve in F2.
Armaan Ebrahim (IND)
2008 season: 7th in Formula V6 Asia
It's four years since he made his A1GP race debut aged just 16, and his Formula Renault and GP2 records since don't show great progress. He has won races in Formula V6 Asia, but is yet to prove himself in Europe.
Henry Surtees (GB)
2008 season: 12th in Formula Renault UK
The son of 1964 world champion John Surtees has packed a lot of races into the past two years, mainly in Formula BMW and Renault. He was a winner in BMW, but didn't make as much progress as he'd have liked in Formula Renault last year.
Tobias Hegewald (D)
2008 season: 5th in FRenault Eurocup
He's had four seasons in single-seaters so far, and began to bloom last year by running up front in the regional Formula Renault North European Cup. He made his FR3.5 debut with Interwetten at Spa earlier this month.
Pietro Gandolfi (I)
2008 season: 26th in Swiss FRenault
Aside from a handful of Italian Formula Renault outings in 2006, Gandolfi's only racing experience to date is in the Swiss FRenault championship, in which he finished 26th last season. Don't expect him to be a title contender.
Nicola de Marco (I)
2008 season: 4th in Spanish Formula 3
A race winner in Spanish Formula 3 last season, but he was well off the pace at the end-of-season Macau Grand Prix. The Italian is another with a steep mountain to climb before he can think about challenging at the front.
Jack Clarke (GB)
2008 season: 5th in Formula Palmer Audi
Clarke had a handy couple of seasons in Formula Palmer Audi, winning a couple of races each year, but he couldn't quite join the title battle on either occasion. He will be another looking to take a step forward in Formula 2.
Robert Wickens (CDN)
2008 season: 12th in FRenault 3.5
One of Red Bull's favoured junior drivers, Wickens starts as an expected title contender in F2, arriving with race-winning pedigree in Formula Renault 3.5, the F3 Euro Series, A1GP and Formula Atlantic.
Mirko Bortolotti (I)
2008 season: Italian Formula 3 champion
Bortolotti joined Wickens on Red Bull's driver scheme on the advice of Ferrari, following his impressive F1 test prize after winning the Italian F3 crown. But this year's opposition will be the highest calibre he's faced yet.
Mikhail Aleshin (RUS)
2008 season: 5th in Formula Renault 3.5
He has been around the World Series by Renault scene in Europe for a long time but has only amassed two wins in FR3.5. Red Bull has shifted him into F2 this season following three years with Carlin Motorsport.
Edoardo Piscopo (I)
2008 season: Italian Formula 3 runner-up
A former Red Bull junior, who was dropped after a disappointing debut F3 Euro Series season in 2007. He won seven races and finished runner-up to Bortolotti in Italian F3 last year and is eager to succeed on the international scene.
Carlos Iaconelli (BR)
2008 season: 28th in GP2
The Brazilian made his GP2 debut last year but never made the top 10. He's also posted rather average results in Formula Renault 3.5, Formula Master and GP2 Asia in the past couple of years, but his F2 testing pace has been promising.
Natacha Gachnang (CH)
2008 season: 3rd in Spanish Formula 3
Gachnang is the cousin of grand prix driver Sebastien Buemi. She finished third in Spanish F3 last season and previously scored a handful of podiums in German Formula BMW and one in German F3, before a short spell in Star Mazda.
Jens Hoing (D)
2008 season: 17th in German Formula 3
Hoing looked set to lose his F2 drive after a contractual dispute, but a late deal has him back on the list in time for Valencia. He didn't make much progress in three years of German FBMW and little changed in German F3 last year.
Kazim Vasiliauskas (LT)
2008 season: 21st in Formula Renault Italy
The Lithuanian had an uneventful debut season last year in Formula Renault on the continent, but he's contesting Formula Palmer Audi as well as F2 this season and has already notched up his maiden victory.
Andy Soucek (E)
2008 season: 14th in GP2
The former Spanish F3 champion is another expected to run at the front of F2, having won in Formula Renault 3.5 and picked up podiums in GP2 with DPR and Super Nova in the past couple of years. Starts the season as title favourite.
Henri Karjalainen (FIN)
2008 season: 17th in Formula Atlantic
Karjalainen made his racing debut in German Formula BMW and went on to finish runner-up in F3 Asia Pacific in 2007. He even made a cameo appearance in GP2, but didn't do much in Formula Atlantic last year.
Tom Gladdis (GB)
2008 season: 6th in Star Mazda
The British teenager had a quiet first year in cars in Formula BMW two years ago, but things picked up last season when he took his first win in North America's Star Mazda championship. He's back to see if he can repeat that form in Europe.
Milos Pavlovic (RS)
2008 season: GP2 (three rounds)
Comfortably the oldest driver in F2 (even after 'losing' a couple of years!), he's been around since Formula Vauxhall in the UK in the late 1990s. He's collected Italian F3 and World Series Lights titles along the way.
German Sanchez (E)
2008 season: Spanish Formula 3 champion
Reigning Spanish Formula 3 champion moves on from the category after three years to join Formula 2. How well he goes will be a good indication of the competitiveness of F3 on the Iberian peninsula.
Jason Moore (GB)
2008 season: FPA champion
Moore is the fourth FPA graduate to join F2 this season and was the pick of the quartet on his way to the title last year, in just his second season of racing. He'll have a lot to learn in a big step up this year though.
Philipp Eng (A)
2008 season: German F3 (two rounds)
Eng took a couple of wins on his way to runner-up in German FBMW in 2007, before winning the category's World Final. A planned graduation to the F3 Euro Series didn't come off, so he'll be eager for a full campaign this season.
