Everything is new for 2013 at Toro Rosso. Except the drivers. And the steering wheel. That's from last year. But other than that, it's a whole new world.
The STR7 was pretty much an evolution of the STR6, and since both previous cars had some problems with weight distribution, the old design had to go if they wanted to see significant improvement. The new STR8 was designed by Luca Furbatto and technical director James Key, who came from Sauber in September to take over from Giorgio Ascanelli.
