He belongs to the Sperafico family of racing drivers, which includes twin brother Ricardo (with whom his career has been closely linked), along with cousins Alexandre and the late Rafael.
For the following year, the brothers switched to the more prestigious International Formula 3000 championship; Rodrigo signed for Coloni alongside the experienced Fabrizio Gollin, whilst Ricardo partnered Antônio Pizzonia at the Super Nova Racing-run Petrobras Junior Team.
[5] Rodrigo began the championship strongly, winning the first race of the season at his home track of Interlagos, but was fortunate to take the victory as hitherto dominant leader Tomáš Enge suffered a mechanical problem.
[6] He then finished a close second to eventual title winner Sébastien Bourdais at the next race in Imola to take the championship lead.
During 2004, Sperafico moved back to Brazil to drive in the Stock Car Brasil championship, his single-seater career having effectively ended.
In his strongest season to date, which included three pole positions and two victories, Rodrigo finished runner-up to champion Cacá Bueno.
[9] Sperafico moved to a Mitsubishi Lancer run by the Avallone Motorsport in 2008 called Terra Racing team for 2008, but faded to 14th in the championship.
