Putting his stamp on the F2 series
With a strong rookie season behind him, Louis returns to the FIA Formula 2 Championship with the Ferrari Driver Academy-affiliated Charouz Racing System squad.
Louis will be getting to grips with the F2 category's brand-new Dallara chassis and 3.4-litre V6, turbocharged Mecachrome engine package in 2018 and he'll be proudly carrying the Ferrari Driver Academy logo on his car during the 24-race season.
With a year of F2 experience behind him, Louis is expected to be one of the pacesetters during the upcoming season.
Learning a new category
As an F2 rookie, Louis' objective during the 2017 season was to learn everything that's required to be successful in the FIA Formula 2 Championship category - especially the characteristics of Pirelli's unique tyres.
Louis showed an impressive ability to adjust quickly to F2 competition as he lined up for the Racing Engineering and Team Rapax squads. He finished 20 of the 22 races during the season, earning a season-best result of P4 in the Sprint Race at the Italian Grand Prix.
The rookie takes 13 victories
Louis' career took another significant step forward with a hugely impressive debut season with Fortec in the Formula V8 3.5 championship.
Now a member of the Renault Sport Academy, Louis consistently beat drivers with much more experience to claim two outright race wins and nine further podiums. His achievements secured him the championship runner-up position and the prestigious ‘Rookie of the Year’ crown after 13 race wins from the 18-round season.
Louis continued to hone his skills with eight appearances in the ADAC GT Masters and got his first taste of F2 competition with a confident one-off appearance at the last round of the season in Abu Dhabi.
A championship-winning season
The 2015 season was when Louis really found his competitive edge.
He dominated the Formula Renault 2.0 NEC series to win that title, before adding Formula Renault 2.0 Eurocup runner-up status to his career record a short while afterwards.
With an eye on the future, Louis also made his debut in the Formula Renault 3.5 Series with a one-off appearance at the fifth round in Austria.
Meanwhile, Louis' head-turning achievements were getting noticed in the wider motorsport community and he was selected to join the BMW Motorsport Junior Programme. His potential was recognised when he was named BMW Motorsport Junior of the Year.
Making his mark in Formula Renault
Louis' second season in the Formula Renault 2.0 NEC series started with a win at the opening round at Monza.
He finished the season as runner-up after securing four more podiums. Louis also made six appearances as a guest driver in the Eurocup Formula Renault 2.0 series.
Showing speed and determination
Louis moved into the Formula Renault 2.0 NEC series in 2013, contesting his rookie season with Josef Kaufmann Racing and immediately impressing with his speed, determination and mature race craft.
Impressing at an early age
The bug for competitive driving bit at the age of 10 and Louis quickly went on to win two prestigious karting championships in Switzerland, before successfully graduating to single-seater competition in 2012 and narrowly missing out on the BMW Talent Cup in Germany that same year.
Louis in profile
Louis Delétraz is a Swiss racing driver that currently stands one step away from realising his Formula One dream.
Having honed his skills in Europe's junior formulae, the 20-year-old's progression through the motorsport ranks has been impressive and he's considered one of the world's best young motor racing talents.
His title-winning success in the 2016 Formula V8 3.5 championship paved the way for Louis to graduate to the FIA Formula Two Championship in 2017.
Although the priority was to learn the F2 category during his first season, Louis showed his ability to adapt quickly and his F2 pace was rewarded with a season-best 4th place finish at the Italian Grand Prix.
With a solid first season of F2 competition behind him, Louis will drive for Charouz Racing System in 2018 - a team that represents the 'Ferrari Driver Academy' programme.
The 2018 season is expected to be one in which Louis, who is mentored by Haas F1 Team driver Romain Grosjean, stamps his authority on the F2 category.
