Daniel Ricciardo has saไid that the new Toro Rosso F1 challen🅰ger is a totally different machine to the one it will replace.

The Faenza-based team endured a difficult season in 2012 as both Ricciardo and Jean-Eric Vergne struggled to get the best from the STR07, which meant the team ended the campaign down in ninth in🎃 the championship with just 26 points.

Both drivers have however been retained for the 2013 campaign, when the team will hope to benefit from the input of new technical director James Key, and Ricciardo admitted that the STR08 had undergone numerous changes to help t🔯he Italian squad move forwards.

"I have already seen the new car," he told Autosprint. "When you examine it more closely, it is very d⛦ifferent to the old one.

"I believe that i♉t is better. In any case, it's not on🦂e of those cars that looks a total copy of the [previous] one, as though nothing has changed."

The Australian also admitt⛄ed that he was well aware of the need to improve his results on track if he wants to realise his potential.

"I'm aware of that, and I know that my targets in 2013 will have to be more ambitious," he said. "My Achilles heel is that this year, in the fi💖rst part of the season, I wasn't aggressive enough in the races. In some aspects I was the opꦏposite of Grosjean."
