The Toro Rosso STR14 is the last car James Key developed for the team, before heading off to McLaren. It clearly built on the design of the STR13, but with Red Bull Racing also going for Honda power, the team were able to share some parts again with Red Bull Racing, supplied through Red Bull Technology, the technical spinoff for both teams. As a result, apart from sharing the Honda RA619H power unit, the gearbox and rear suspension are identical with the Red Bull RB16.

The front suspension is a pushrod design utilising carbon wishbones. These items along with a number of the electronic components are designed and produced in Faenza.

The braking and fuel systems have been produced in collaboration with Red Bull Technology, while the differential and the hydraulically operated carbon clutch are common across the two teams.

Results

2019 was a great year for the Faenza team, finishing sixth in the Constructors’ Championship, thanks above all to the two podium finishes, one each for Daniil Kvyat and Pierre Gasly, in Germany and Brazil respectively. The team, in its last year as “Scuderia Toro Rosso” before being renamed “Scuderia AlphaTauri“, brought its points haul to a total of 500 over its 14 years in Formula 1 to date.
