Toro Rosso STR5 and Red Bull RB6 – Born sisters but grown different


 

Toro Rosso built its 2010 contender the STR5 using its own sources for the first time rather than copying the designs of the sister Red Bull team.  Nevertheless STR5 is not a completely new car as it bears similarities to the STR4 and the RB6 especially at season start .  The differences were becoming more and more during the season as Red Bull and Toro Rosso followed completely different development paths .
