In late November 2008, Red Bull regained total ownership of Toro Rosso after buying back Berger's share of the team.
Minardi owner Paul Stoddart claimed to have had 41 approaches to buy the team, but preferred to sell it to someone who could 'take it further' than he could and who would maintain it in its traditional base in Italy.
[6] The continuation of this arrangement after the Red Bull takeover caused friction with other teams, in particular Super Aguri and Midland who felt that the engine conferred too much of an advantage.
As the season progressed, the Toro Rossos began to struggle in qualifying as their competitors developed their new V8 engines to rev closer to 20,000 rpm to get more power.
For the 2007 season, Toro Rosso began using the 2006-specification Ferrari 056 V8 engine rather than 2007 works spec due to cost reasons, taking over the contract that their senior team broke from by switching to customer Renault power.
Following the European Grand Prix, Speed was dropped under controversial circumstances and was replaced by BMW Sauber development driver Sebastian Vettel who was later confirmed for 2008.
With the 2008 Concorde Agreement outlawing customer cars from 2010 onwards, Dietrich Mateschitz put the Toro Rosso team up for sale in March 2008.
In mixed conditions, Lewis Hamilton needed 5th place to clinch the championship, and was running in this position when he was overtaken by Vettel with two laps remaining.
After the previous year's success, several drivers wanted to drive for Toro Rosso, including Takuma Sato (who even did three tests with the team) and Bruno Senna.
Monaco saw Buemi in the points in tenth, ahead of Nico Rosberg whilst Alguersuari crashed out along with Vitaly Petrov in an incident that brought out the red flag to the race.
In the British Grand Prix, Alguersuari scored a point with a tenth-place finish while Buemi collided with di Resta, which forced his retirement from the race.
Due to their car's high straight-line speed, Buemi picked up points with ninth, while Alguersuari overtook Rosberg's Mercedes on the final lap to take the team's best race result in 2011, of seventh place.
[24] Despite some better results in the final races, Toro Rosso suffered a poor season which saw the team finish in ninth place in the Constructors' Championship, only ahead of Caterham, Marussia and HRT.
[25] The team did not make the start they wanted at the Australian Grand Prix after Vergne finished 12th and Ricciardo retired due to an exhaust problem.
However, at the Malaysian Grand Prix, Vergne managed to score the team's first point of the season with a respectable 10th place, while Ricciardo retired in 18th due to another exhaust problem.
In Monaco, fortunes turned around for Vergne as he managed to finish an impressive 8th and score 4 points while Ricciardo, like his teammate in Spain, suffered a collision and had to retire from the race.
Red Bull driver Mark Webber announced he was to retire from Formula One at the end of the season, leaving a vacant seat at Toro Rosso's sister team.
Ricciardo impressed his future employers with a strong 7th position in qualifying while teammate Vergne started 10th with a mistake in Q3 ruining his chancing of improving on his previous time.
Toro Rosso signed a long-term agreement with Renault to use their same-spec engines as it was used by Red Bull Racing, Lotus and Caterham teams from 2014.
On 21 October 2013, it was announced that Jean-Éric Vergne would remain with the team for a third successive season, and will be partnered by Daniil Kvyat, who was a race-winner in the GP3 Series and the FIA European Formula 3 Championship in 2013.
[34] After a controversial crash in Russia, Kvyat was brought back to Toro Rosso from Red Bull, with Max Verstappen taking his place.
Gasly was absent in order to participate in the final round of the Japanese Super Formula Championship, so Brendon Hartley replaced him for this race.
[40] After the 2017 Mexican Grand Prix, Helmut Marko said that Daniil Kvyat would not be returning to Toro Rosso and that the team would race with Brendon Hartley and Pierre Gasly for the remainder of the season.
In addition, the Toro Rosso-Honda partnership also included Japanese Honda staff would work at their Faenza base as well as official team vehicles and brand endorsements.
He suffered a gearbox failure in China, the same race in which he and Gasly crashed at the hairpin on Lap 30, but scored his first point in Formula One with 10th place in Azerbaijan.
Gasly was eliminated by a heavy first-lap collision with Romain Grosjean in Spain, but finished a respectable 7th at the following race in Monaco whilst Hartley retired after Charles Leclerc collided into his rear after a brake failure.
The team scored an excellent result at the rain-affected German Grand Prix, where clever strategy calls allowed Kvyat and Albon to finish 3rd and 6th respectively.
This was Toro Rosso's first podium finish since their shock win at the 2008 Italian Grand Prix, and their best ever race result in terms of total points.
Prior to the Belgian Grand Prix, Albon left the team after being promoted to Red Bull, replacing Gasly who returned to Toro Rosso.
On 6 September 2011, the week before the Italian Grand Prix, the team confirmed that they had received a sizeable investment from Spanish petroleum group Cepsa (only sponsorship but not de facto fuel and lubricant supplier) which ended after the 2015 season.
