Marussia have confirmed Ferrari as their new engine supplier with the Italian manufacturer providing them 1.6-litre V6 turbocharged power units from 2014.
The Banbury squad have made use of Cosworth engines since their debut in 2010, but they have been forced to switch supplier with F1 switching to the new V6s next year.
The team confirmed on Tuesday that they had signed a technical partnership with Ferrari.
A statement from CEO Andy Webb said: "The importance of this development to our team cannot be overstated. Not only will we benefit from a customer supply from the most successful engine manufacturer in Formula One's history, but this also provides further confirmation, if it were needed, of our commitment to the sport and determination to maintain our progression towards our long-term ambitions.
"The new powertrain regulations being introduced next year represent the most substantial engine development within the sport since the introduction of the V8 formula and are all the more significant for the increased contribution of the Energy Recovery System.
"We look forward to working with Scuderia Ferrari during this exciting new era of Formula One competition."
Webb also paid tribute to Cosworth.
"We would also like to take this opportunity to thank Cosworth, with whom we have partnered since our debut season in 2010," he continued.
"We have shared an important part of our team's journey together and Cosworth have been an integral part of our clear progression. We will continue to work together during the latter half of the season to ensure we all achieve our combined objectives before Cosworth leave the sport."
