New diffuser for Toro Rosso in Barcelona

The Scuderia's Toro Rosso's STR4 will be fitted with a brand-new diffuser for the Spanish Grand Prix on 10 May. Team boss Franz Tost said: "We will have some updates to the rear diffuser, giving us more downforce. The entire field is very closely matched and so the key to doing well on Sunday is to qualify well, which is difficult, given you have around five cars in a tenth, so that getting out of Q1 involves being very well prepared."
