On the eve of pre-season testing at Jerez, Toro Rosso have unwrapped their STR8 at the Spanish circuit.
Daniel Ricciardo and Jean-Eric Vergne were on hand for the unveiling, taking the covers off the new car, which features a vanity panel covering the stepped-nose.
The STR8 retains the undercut sidepods of its predecessors while including a McLaren-style exhaust.
The new car is the first Toro Rosso to receive input from technical director James Key, who joined the team from Sauber last season.
Last season Toro Rosso finished ninth it was a disappointing campaign. This year team boss Franz Tost wants a marked improvement.
"We have worked hard and hopefully done a good job these past months," said Tost.
"The three test sessions in Spain in February will begin to reveal some trends among the teams, but until we all line up on a real race grid, there will be no clear picture of what we can expect.
"Nevertheless, we have set ourselves a target of finishing sixth in the Constructors' classification."
He added: "Both drivers did a really good job last year, and I'm convinced if we supply them with a good car they'll come up with surprise results."
"Naturally, we will be expecting more from them this year as they both tackle their second full season of Formula 1.
"However, we are well aware it is up to us to provide them with a car that's capable of allowing them to show their undoubted talent.
"After taking part in the sport's longest ever season in 2012, every team now knows just how tough a task faces us all again, even if at the moment, there are only 19 races on the calendar."
