Renault are not expecting instant success when they return to Formula 1 as a full works team next season.
After months of protracted negotiations Renault confirmed late last week that they would be back as a constructors in 2016.
The company has acquired the Lotus outfit, the same team they sold to Genii Capital in 2010.
Set to race under the Renault name next season, CEO Carlos Ghosn has warned against expecting immediate success from the team.
"I think, given how motivated our teams are, it will take three years to be competitive," he told France's Le Figaro newspaper.
"We will also continue to develop our activity as an engine supplier, though only according to our own team's interest."
He added: "We are deeply attached to Formula One, and I was also able to appreciate how a great number of F1 people – from FIA, FOM, or even our rivals – were attached to Renault. Our associates are also highly motivated to see us in F1.
"At Renault, there is a passion for racing."
Future details on Renault's plans for their first season back at a works team will only be revealed in January.
"We will wait a few weeks," said Ghosn.
"I refer to a meeting in January 2016, when we will explain the organisation, goals, strategy and we will also talk about drivers and partners."
