Last but certainly not the least team to unveil their 2017 Formula 1 challenger is Toro Rosso, with their STR12. It had first been spotted, however, at its track debut in Misano last week.

The car now sports a new livery as compared to their previous paint scheme over the past seasons. A red, silver and blue livery is used on the car; same as the one used in Red Bull's cola beverage.

Like most 2017 Formula 1 cars, the STR12 features a sharkfin tail and a more flattened nose due to the regulation changes made this season. A aggressive front aero and the wider rear end can also be seen. However, the design is a bit more tamed compared to the Red Bull challenger.

Along with the new aerodynamic design, powering the STR12 would be new Renault power units. Compared to the previous season where they ran year-old Ferrari engines, the new Renault engines should hopefully give the STR12 opportunities to finish better.

Driving for Toro Rosso would be Carlos Sainz and Daniil Kvyat. The Spaniard being his third season with the team and Kvyat returning to Toro Rosso after losing his seat at Red Bull to Max Verstappen.

Toro Rosso will join the rest of the Formula 1 teams at Barcelona when official pre-season testing commences.
