New Renault chief technical officer Bob Bell says the team has "tremendous potential" which needs to be exploited.
Bell has rejoined Renault following spells at Mercedes and Manor, with the remit to oversee the partnership between the chassis and power unit sides of the team.
With Enstone having produced race-winning cars in both 2012 and 2013, and Renault winning four consecutive championships as an engine supplier from 2010-13, Bell is excited by what can be achieved if he can get both aspects of the team working together successfully.
"There is tremendous potential to be tapped on both sides of the equation," Bell said. "To characterise the current situation in both organisations, firstly you have Enstone, which is an organisation that has been starved of resources in recent times, but structurally is pretty sound.
"Viry, on the other hand, could be characterised as being resourced well enough to do a credible job however recent history has seen a very difficult situation with the change to the latest power units and this has impacted on how the facility operates.
"The key for Viry is galvanising the leadership and direction with the new opportunities that a works F1 entry provides. The focus is more structural whereas at Enstone it’s more resource-based. We’re clear on what the issues have been in the past and we’re working on putting them right."
