He won the Spanish Junior Championship that year, and retained the title in 2004, while also accumulating further international experience at the WRC events in Argentina (retired), Germany (19th), France (13th) and Spain (20th).
In this last event, he switched from the Lancer Evo to a Citroën C2 S1600, and for 2005 he committed to a full season driving the C2 in the Junior World Rally Championship (JWRC) with Belgium's Kronos Racing team.
These showings earned Sordo a subsequent drive in a Kronos Total Citroën-prepared Xsara World Rally Car as the team's third driver in the 2006 season, although the initial plan - latterly dropped - was for the Spaniard to combine a piecemeal World Rally Car programme with a simultaneous defence of the JWRC title in the C2.
His early results though, including successive podiums at the Rally Catalunya and the Rallye de France, proved sufficient to not only expand his complement of contested events, but also ensure promotion to the second driver berth from the Rallye Deutschland onwards, alongside Sébastien Loeb and ahead of team-mate Xavier Pons.
With 65 points, he placed fourth overall in the drivers' championship, behind his teammate Loeb and BP Ford World Rally Team's Marcus Grönholm and Mikko Hirvonen.
Back in the World Rally Championship, Sordo took fourth place in Finland and went on to drive his C4 WRC to three consecutive runner-up finishes behind his teammate Loeb; in Germany, New Zealand and Spain.
At the season-ending Wales Rally GB, Loeb and Sordo secured the team their fourth manufacturers' crown by finishing first and third, respectively.
For 2012 he continues his partnership with MINI for their first full season beginning with the Monte Carlo Rally, where he took his first podium for 2012 finishing in second place.
Sordo was set to replace Ford's number one driver Jari-Matti Latvala in Argentina, after the Finn was injured in practice for the upcoming event, the only event he drove for Ford, after which he competed in New-Zealand, Germany, France and Spain for Prodrive as the team tried to focus on the sealed surfaces.
Since the 2014 season Sordo moved to the new Hyundai Motorsport team and drives the second or third car in selected events.
In the next race in Rally Monza, after leading the overall virtually, finally finished third, helping Hyundai win the constructors' championship.
