Toro Rosso's Formula 1 cars will be powered by Renault engines from the start of the 2014 season, the French manufacturer has confirmed.

The deal will see the Italian outfit join sister team Red Bull in being powered by Renault as they leave Ferrari behind.

"We are very pleased to have reached an agreement to use Renault power units from the 2014 season onwards, when the new regulations will present interesting challenges," Sky Sports News quotes Toro Rosso Team Principal Franz Tost as saying.

"It is particularly important that we have managed to finalise our plans early, so that we can be as well prepared as possible for next year.

"While looking forward to working with Renault, I would also like to thank Ferrari, our engine supplier since 2007. They have provided us with an extremely effective and reliable engine and an excellent service."

At today's Monaco Grand Prix, Jean-Eric Vergne will start the race 10th for Toro Rosso, with teammate Daniel Ricciardo directly behind him in 12th.
