Ricciardo started karting at the age of nine and entered numerous karting events since. In 2006, he won a scholarship into the Formula BMW Asian championship with Eurasia Motorsport. In the nineteen race championship, the young Australian took two victories, both at Bira, and also scored a pole position at Zhuhai during his début season where he finished third in the Drivers' Championship with 231 points; 59 off the champion Earl Bamber.
In August that year he was given an outing with Motaworld Racing to race one of their Formula BMW cars at the eighth meeting of the British championship. Despite retiring from the first race, Ricciardo recovered to finish eighth in the second race and took three championship points in his only entry in the British championship. At the end of the year, he entered the Formula BMW World Final with Fortec Motorsport where he finished in fifth position, fourteen seconds off winner Christian Vietoris.
2007 saw the Australian switch categories to Formula Renault with Rp Motorsport, entering the European and Italian championships of the category, although mainly focused on the latter series as he entered fourteen races to the four entries he took in the European championship. He finished the year seventh in the Italian series with 196 points and scoring a podium at Valencia.
The Australian stayed in Formula Renault for a second year in 2008, entering the European and Western European championships. During the mid–part of the season, Ricciardo made his Formula Three début at the Nürburgring, entering SG Formula's Formula Three Euroseries team. Despite only a short amount of experience in the car Ricciardo qualified in eighth for the first race which later converted into sixth in the race after James Jakes and Christian Vietoris stalled on the grid. By the end of the year, the young driver took his first European title in the Western European Cup and finished second in the Eurocup to Finn Valtteri Bottas.
Two Red Bull Junior rookies dominated the 2008 British Formula 3 Championship: Jaime Alguersuari (ESP) took the title; Brendon Hartley (NZL) finished third in the overall standings. The two of them together won no less than ten races.
Daniel Ricciardo, the only Australian in the Red Bull Junior Team, followed in the tracks of these two successful Juniors in 2009. he became the British F3 International Series Champion with 6 wins and 12 podiums.
On 11 November 2010, Ricciardo was confirmed as the single driver to represent Red Bull Racing at the end-of-season young drivers test at the Yas Marina Circuit, on 16–17 November. Days after completing this session Ricciardo was confirmed as Toro Rosso's test and reserve driver for the 2011 season. At the 2011 Australian Grand Prix, Ricciardo was placed 16th on the timesheets after opening practice.The Australian managed to later finish eighth in practice for the wet Turkish Grand Prix Friday practice session, ahead of his more experienced competitor, Sebastian Buemi.
Finally, in December 2011, it was confirmed that Ricciardo would drive for the Scuderia Toro Rosso for the 2012 season, alongside Frenchman Jean-Éric Vergne. Ricciardo's time had come! At the Australian Grand Prix on 18 March 2012, Ricciardo managed to overtake his team-mate Vergne late on the last lap to come home in ninth place, securing his first two World Championship points.
As we move into 2013, Ricciardo sits 18th in the Drivers Championships. Only once did Ricciard retire during the 2012 season, the second best record of consistency in the sport, and twice he cracked the top 10. Scuderia Toro Rosso has officially re-signed Ricciardo for the 2013 season and it is safe to assume we can expect big things from this young Aussie racer.
