The Toro Rosso STR9 is a Formula One racing car designed by Scuderia Toro Rosso to compete in the 2014 Formula One season.[1] It was driven by Jean-Éric Vergne and 2013 GP3 Series champion Daniil Kvyat,[2] who replaced Daniel Ricciardo after Ricciardo moved to Red Bull Racing. The STR9 was the first Toro Rosso car to use an engine built by Renault,[3] the Energy F1-2014.[4] The Toro Rosso STR9 was also the first Italian-licensed F1 car to use Renault engines since the Benetton B201 in 2001 and was also the first Faenza-based Formula One car to utilize turbocharged engines since the Minardi M187 in .
2014 confirmed Toro Rosso's position as a respectable midfield runner unable to make the final breakthrough needed to become a top team. The team's package was quick and reliable, but not quite enough to regularly score points. Indeed, Vergne and Kvyat finished just outside the points, no less than eight times. The highlight of the year was Vergne's run to sixth at the 2014 Singapore Grand Prix to score the team's season highest finish. But 6th place finish at Singapore was not enough for Vergne to remain in Toro Rosso squad for 2015 season and hence he was replaced by Carlos Sainz Jr. for the following season. Kvyat, despite a points finish in the first race of the season, lost his motivation after a sequence of bad luck and narrowly missing out on further points. He decided to move to Red Bull Racing for the following season after Sebastian Vettel decided to move to Ferrari team, and would be replaced by future world champion Max Verstappen.
The team eventually finished seventh in the Constructors' Championship with 30 points. This was their 2nd best WCC position so far, but there was still some way to go to take on the likes of Red Bull, Mercedes, Ferrari, Williams and McLaren.
