While starting his professional life as a salesman, Julien Ingrassia discovered rallying and made his debut as a codriver in 2002 in France's Critérium des Cévennes.

Despite his late arrival in motorsport, it only took Julien Ingrassia two seasons in the WRC class together with Sébastien Ogier to star at the highest level of rallying.

After their departure from Citroën, Julien Ingrassia and Sébastien Ogier linked up with Volkswagen Motorsport in 2012, choosing the German manufacturer instead of Ford: this meant skipping the 2012 WRC championship in order to fully develop the new Polo R WRC, but they indeed experienced a very busy year in 2012, competing in almost the entire season at the wheel of a Skoda Fabia S2000 while developing the new car for 2013.

Ogier and Ingrassia ended the weekend on the podium, and then went on to win Rally Sweden, a real accomplishment given the Scandinavians' hegemony on their home ground.

Also victorious in Mexico, Portugal, Italy, Poland, Australia, Spain and Wales, Julien Ingrassia and Sébastien Ogier clinched their second title on the penultimate round of the season.

With a total of 24 victories in five seasons, he was also at that time the third most successful co-driver in the WRC (tied with Luís Moya, who retired in 2002), behind Timo Rautiainen (30) and Daniel Elena (78).

After winning also in Mexico and France, the rest of the season was less successful for them, to the point that they were only third in the championship three rounds from the end, behind Thierry Neuville and Ott Tänak.

For the sixth time in a row, they began the season with a win at Rallye Monte-Carlo, after an intense duel with Thierry Neuville and Nicolas Gilsoul and a gap of just 2.2 at the end, the smallest in the event's history.

For the first time in six years, they were beaten at Rally Monte Carlo, but scored their first win in the Toyota Yaris WRC in Mexico, which took place in early March.
