|2018||Third and Reserve Driver for Renault Sport Formula One Team as well as competing in the FIA Formula 2 Championship with ART Grand Prix.|
|2017||Jack remained in GP3 for 2017 and switched to French outfit ART Grand Prix. He blitzed to a dominant pole position at the season-opener in Barcelona, but technical issues hampered Jack in the races. He brushed that aside by claiming back-to-back second places at the following rounds in Austria and Great Britain. In Hungary he took 31 points from a race – the first GP3 driver of the year to do so – when he won from pole and stormed to the fastest lap around the Hungaroring.
Jack added more podiums to his tally at Spa and Monza to remain in the title hunt, but he ultimately fell short of winning the championship at the penultimate round in Jerez before ending the season in Abu Dhabi with a frustrating outing. He tested Formula 1 machinery for the first time in September, getting behind the wheel of a Renault-powered E20 Formula 1 car at Jerez.
|2016||In 2016, Jack began his maiden season with the Renault Sport Academy driving for Arden International in the GP3 support series. Despite a difficult start to the year, adapting to the bigger cars and new tyres, Jack finished the season in fifth place and was the driver to beat in the second half of the season. In fact, from the final nine races, Jack failed to finish on the podium just twice, taking his first GP3 win at Spa-Francorchamps.|
|2015||Jack’s breakthrough season came in 2015 as he scooped a hat-trick of championship titles. He first clinched the Pro Mazda Winterfest crown in the USA during the late winter months before storming to the Formula Renault Alps title courtesy of four wins. He capped off a memorable season by claiming the highly-competitive Formula Renault Eurocup championship with eight podiums, five of which were victories, earning him a spot with the Renault Sport Academy.|
|2012-2014||Jack’s single-seater career began in 2012 in the Dunlop Intersteps Championship with Fortec Motorsport, where he finished third in the championship. His first taste of Renault came a year later when he claimed runner-up spot in the Formula Renault NEC series. 2014 saw Jack move up to compete in the Formula Renault Eurocup, where he bagged one victory – at Hungary – on his way to seventh in the championship.|
