Design

The car was launched on 31 January 2015.^[3] Toro Rosso introduced an extensively modified STR10 for the final pre-season tests at the Barcelona circuit in late February, with a shorter nose, new aerodynamics and a new suspension. According to the team's technical director, James Key, this revised STR10 was "actually the 'real' racecar."^[4]

Racing history

Verstappen at the Belgian Grand Prix

The car proved quite competitive throughout the season, managing to score 67 points and a pair of 4th places for Verstappen in the Hungarian and United States Grands Prix. The results allowed Toro Rosso to end the season with 7th place in the World Constructors' Championship, 11 points behind the Mercedes-powered Lotus. This was the last Renault-engine Toro Rosso, before the team returned to Ferrari power units for the 2016 season.

Livery

Despite having a very similar livery to previous seasons, it had a minor change on the pinstriping. This was the fourth and final year for both Nova Chemicals and Cepsa sponsorships as both were withdrawn from the team. Falcon Private Bank was replaced with Sapinda Group.

Notes

1. Despite CEPSA is an oil and gas company as a major sponsor of Scuderia Toro Rosso since mid-2011 season, the CEPSA branding appears on the STR10, but the car uses Total fuel and lubricants.^[1]
