The Toro Rosso STR5 was a Formula One motor racing car designed and built by Scuderia Toro Rosso for the 2010 season. The car was a significant change for the team as it represented the first chassis they had indigenously-designed and built on their own in Faenza, Italy; prior to 2010, the car was identical to that of parent team Red Bull Racing, circumventing a ban on customer chassis by having both cars designed by a third party. The car, driven by an unchanged lineup from 2009 of Sébastien Buemi and Jaime Alguersuari, was unveiled at the first official test of 2010 on February 1, at the Circuit Ricardo Tormo in Valencia.^[3]

The Toro Rosso STR5 utilized the 2009-spec Ferrari 056 V8 engines instead of 2010-spec.

Season summary

The STR5 struggled throughout the 2010 season with a small number of retirements. On 19 occasions did a STR5 cross the finish line of a Grand Prix, with Buemi chalking up 5 retirements in 19 races, failing to finish a Grand Prix in Australia, China, Spain, Germany and South Korea. Alguersuari meanwhile fared slightly better with 2 retirements. Alguersuari chalked up the first points of the season in Round 3 at Sepang, Malaysia with a 9th place finish. Buemi would score the team's next 7 points with 10th place finishes at the Monaco and Japanese Grand Prix, 8th finish at Canadian Grand Prix and 9th finish at European Grand Prix. Alguersuari added the team's final point at the final Grand Prix of the season in Abu Dhabi.

At the end of the season, Buemi and Alguersuari finished 16th and 19th in the Drivers' Championship respectively, while Toro Rosso finished ninth in the Constructors' Championship, their 13 points being their lowest tally for the second season running.
