Renault look for 'big change'
Barcelona test key to improvement
Renault need "a tidal wave of change" if the team hopes to bounce back from their early season woes, according to tech director Bob Bell.
While Nelson Piquet Jr has yet to score a point this season, suffering two retirements in the opening three races, his team-mate Fernando Alonso has had a far better start.
However, even Alonso's opening stint has not been at the level that the double World Champion was used to during his first stay at Renault.
Although in the past he won races or at least finished on the podium, this year the Spaniard is struggling to even finish in the points as Renault battle with the aerodynamic package of the R28.
"I think 'we need to improve' is a bit of an understatement," Bell told Renault's website. "It needs a tidal wave of change to move us back, but that is what we are here to do.
"Clearly our biggest deficit is in the aerodynamics of the car, but there are mechanical domain improvements that we can make.
"Quite clearly we have got some big steps to make and we need to make them in big steps, not lots of little ones because we don't have the time."
The tech director, however, is hoping that Renault can begin their journey forward at next week's Barcelona test where the team plans to introduce a major aerodynamic update.
"We need to have a very sizeable step," he said.
"We need to make the first step in Barcelona to clearly demonstrate we have made a step forward, and start moving back to the leading three teams and edging away from the gaggle of teams sat behind them.
"(Then) mid season we want to show that is consolidated and that we are right there on the tails of the top three."
