Technical director Mike Coughlan says Williams is aware of where it needs to focus its efforts as it seeks to bounce back from a tough start to the new F1 season in Malaysia.
The team endured a tough start to the new season with the FW35 being off the pace all weekend at Albert Park in both wet and dry conditions.
Valtteri Bottas was at least able to bring home a race finish on his F1 debut in 14th, but Pastor Maldonado span into retirement to cap a weekend where he had qualified only 17th.
With high hopes for the 2013 campaign, the Australian result left Williams needing to regroup with Coughlan hopeful of a step forward in performance at Sepang this weekend.
“Following a difficult opening to the season in Australia, the team has regrouped and been working hard to solve the problems we encountered last weekend,” he said. “We have a good idea where to focus our efforts and learnt a lot in Melbourne which we will implement in Malaysia to continue working to improve the performance of the FW35 throughout Friday testing and into the weekend.
“The Sepang circuit is a technical challenge which is always quite hard on tyres. The high ambient temperatures and humidity also make it a tough race for the drivers, with the weather also playing its part with late afternoon showers common and forecast over the weekend. Our aim is to move forward from where we were last weekend, with a view to end the race with both cars in points-scoring positions.”
