Boss Eric Boullier told Spain's El Pais newspaper that the Enstone based designers "made a commitment to innovation" when devising the R31 car.
Indeed, observers and rivals have lauded the car's innovative front exhaust layout.
"We spent a lot of time thinking about it and discussing it, as it was a risk. But in the end we said 'Why not?'" revealed Frenchman Boullier.
It's too early to say if we can win races
Losing lead driver Robert Kubica to injury was a major blow to Renault's 2011 campaign, but Boullier said the team is hopeful of a very good season.
"I very much respect Ross Brawn, Mercedes and McLaren and I know they have greater resources; if we can stay ahead of them it will be a great success for us," added Boullier.
