The STR14 is, logically enough, the 14th Scuderia Toro Rosso single-seater. It has been designed and built to tackle the 2019 Formula 1 season, the 70th year of the blue riband series of world motorsport.
Development of the Toro Rosso STR14, raced by Daniil Kvyat, Alex Albon and Pierre Gasly, began in 2018 of course, for what is the fifth season of the F1 hybrid era.
The technical sheet
The chassis and aerodynamic components are entirely designed and produced at our factory: the process starts with the Concept Design, Aero & Simulation group’s defining a car concept which is then further developed at our wind tunnel in Bicester, UK.
From there, it is the turn of the Design Office in Faenza to pick up and develop the layout, before the parts are manufactured by our workforce, which specialises in working with carbon and metallics. Then comes quality control, painting and assembly.
The Scuderia Toro Rosso cars are mated to Honda power units that consist of a 1600cc V6 turbo charged internal combustion engine and two electrical generators, the energy from which is stored in batteries.
The generators are the Motor Generator Unit-Kinetic (MGU-K), which takes energy generated by the rear brakes and turns it into electrical energy and the Motor Generator Unit – Heat (MGU-H), which does the same with the heat generated from the exhausts.
2019 F1 Regulations: what’s new on the STR14
In 2019, changes to the technical regulations include a few modifications which change the look of the cars. The changes, the most visible of which are to the front and rear wings, are aimed at making overtaking easier and at allowing drivers to engage in closer combat, thanks to a cleaner airflow.
The two wings are simpler, wider and taller. The front has increased in width by 200mm, in height by 20mm and is positioned 25mm further forward. The rear has also grown by 100mm and 20mm respectively. The DRS opening has also increased by 25mm, which gives the car a significant performance boost.
Also modified are the barge boards and the brake ducts, while the amount of fuel that can be used in a race goes up from 105kg to 110kg. Pirelli continues as F1 sole tyre supplier with 5 different dry weather compounds available (from C1 to C5) and two rain tyres.
However, for 2019, there will only be three colour codes: white-hard, yellow-medium and red-soft.
Whatever compounds are selected by Pirelli from the 5 available for each track, they will always carry the same three colours. This simplification is aimed at helping fans to get a better understanding of the strategies employed by the various teams during the races.
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. 2019 was therefore a record year!
STR14: Toro Rosso’s evolution history
Up until 2009, in other words from the STR1 to the STR9, our cars were built and developed calling on synergies with Red Bull Technology, the technological satellite based alongside our cousins at Red Bull Racing in Milton Keynes.
From 2010, in line with changes to the sporting regulations, Scuderia Toro Rosso became ever more independent, working with complete autonomy on the design and manufacture of its cars, investing in new facilities at the Faenza factory and the Bicester wind tunnel.
As from 2019, while of course adhering to the regulations, we return to sharing certain car components with Red Bull Technology, in order to make the most of the synergies with the Milton Keynes-based team, particularly in light of both teams running the Honda RA619H power unit.
The parts the two cars have in common are the rear suspension and gearbox.
The gearbox is mounted longitudinally, within a carbon housing. The eight speeds are hydraulically operated. The suspension, which is a pullrod design, features carbon composite arms, inboard dampers and torsion bars.
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 carbon clutch, also hydraulically operated, are common across the two teams.
The seat is moulded to each driver’s body shape and is made in-house in carbon, while the exhausts, along with the power unit, are supplied by Honda.
Finally, when it comes to the weight of the Scuderia Toro Rosso STR14, the needle on the scales stops at 743kg, which includes a minimum of 80kg for the driver and seat combined.
