Facu Regalia

Regalia began karting in 2006 and raced primarily in Spain for the majority of his karting career before transitioning to formula cars.

Regalia entered formula racing in 2008 in the newly created Formula BMW Europe championship with EuroInternational, finishing sixteenth overall in the championship with nine points-scoring finishes and 60 points. He remained in the series for 2009, switching to Josef Kaufmann Racing, and improved to eighth in the standings with thirteen points-scoring finishes from sixteen races. In 2010, Regalia completed a third Formula BMW season with Eifelland Racing, again finishing eighth in the championship and recording his first podium at Zandvoort.

In 2011, Regalia moved to the Italian Formula Three Championship with Arco Motorsport, finishing tenth overall. He recorded two podiums across the season, at Imola and Vallelunga. He also made an additional appearance in the Formula 3 Euro Series at Hockenheim with Mücke Motorsport, taking two tenth-place finishes in the weekend before retiring in the third race.

In 2012, Regalia switched to the European F3 Open Championship with Campos Racing, a move that brought considerably more success. He finished fourth in the championship with three race victories and six podiums in sixteen races, totalling 186 points. Alongside the F3 Open campaign he also competed in the Auto GP World Series with Campos Racing, ending that season seventh.

Regalia made his GP3 Series debut during the fourth round of the 2012 season at Silverstone, replacing Jakub Klášterka at Jenzer Motorsport. He did not score points in those initial outings.

In 2013, Regalia stepped up to a full GP3 campaign with ART Grand Prix, one of the championship's leading operations. Over sixteen races he scored one victory from pole position at the Nürburgring, added six podiums, and accumulated 138 championship points. He finished runner-up in the championship to Daniil Kvyat by a margin that reflected the consistency of his ART team-mate across the year. The 2013 season represented the high point of Regalia's single-seater career.

In 2014, Regalia graduated to GP2 with Hilmer Motorsport. His first eight race starts produced no points; results included multiple retirements at Bahrain, Barcelona, Monaco, and Austria. After four GP2 rounds Regalia left both the team and the championship, ending his campaign early. He finished the season classified 31st.

For 2015, Regalia signed with Zeta Corse for the Formula Renault 3.5 Series, but the team withdrew from the championship due to lack of funding before the season started. An attempt to join Comtec Racing as a replacement ended when Regalia terminated the contract after three days, leaving him without a drive in the European single-seater hierarchy.

He subsequently contested the 2015 Auto GP season with FMS Racing, winning the opening race at the Hungaroring from pole position and adding a second-place finish at Silverstone before the season was cancelled; he was classified second in the standings at the time of cancellation.

Regalia also appeared in the 24H Series endurance races in 2015 and 2016 with MSG Motorsport, racing a Porsche. In 2016 he competed in the Top Race V6 Argentina series in his home country. A brief return to single-seaters came in 2020, when Van Amersfoort Racing invited him as a guest driver for three Formula Regional European Championship rounds at Paul Ricard. As a guest competitor he was ineligible to score championship points.

Regalia's 2013 GP3 runner-up finish with ART Grand Prix remained his career peak, reflecting a driver who was competitive at a high level in junior formulae but who did not secure the financial backing or team environment to push further. He accumulated seven wins and 22 podiums across his international career, covering 137 race starts.
