The Toro Rosso STR12 is a Formula One racing car designed and constructed by Scuderia Toro Rosso to compete during the 2017 Formula One season. The car made its competitive début at the 2017 Australian Grand Prix. It was initially driven by Daniil Kvyat and Carlos Sainz, Jr., however both drivers were replaced by Pierre Gasly and Brendon Hartley towards the end of the season, after the former was dropped from the Red Bull programme, and the latter began a 2018 contract with Renault four races early.[2] [3]
The radical regulation changes meant that the STR12 started on a clean sheet of paper, but it was designed and built by the same people in Faenza and Bicester who produced its predecessor, which was regarded as an excellent package. The STR12 is powered by engines supplied by Renault after the team used 2015-specification Ferrari power units throughout the season;[4] however, the engines were rebadged and the engine and chassis package run under the name 'Toro Rosso'.
See main article: 2017 Formula One World Championship. Aiming high in 2017, two driver changes through the year derailed the team's hopes of securing a sixth-place World Constructors' Championship finish. Sainz had a year of ups and downs with the team, finishing in the points position on nine occasions, but retiring on six occasions. He finished an electrifying 4th place at Singapore.[5] Sainz collected 48 points for the team over his 16 race span at the team. Kvyat had a sub-par year, starting the season off well with a ninth-place finish in Australia. He also scored points in Spain and the United States, but collected only 5 points over the course of 15 races. The Italian team finished the season in 7th place in the Constructors' Standings with 53 championship points.[6]
