Toro Rosso owner Dietrich Mateschitz has warned that the team need to improve after an underwhelming 2012.
The Austrian outfit slipped to ninth in the Constructors' standings this season after notching up just 26 points as the new pairing of Daniel Ricciardo and Jean-Éric Vergne failed to impress. All this while their sister team Red Bull took home the Drivers' and Constructors' titles.
Mateschitz has cautioned that while he doesn't expect STR to battle at the front of the field with Red Bull, more is expected of them.
"Toro Rosso is our rookie team and its goals differ from those of Red Bull Racing," Mateschitz told AUTO.
"But that's not to say we're happy with the development of the car. Significant improvements need to be found and are being called for."
James Key replaced Giorgio Ascanelli as technical director midway through the season and Mateschitz will be hoping the switch begins to pay dividends.
