Williams duo Valtteri Bottas and Felipe Massa were encouraged by the mileage they were able to rack up during wet/dry conditions at the Austrian Grand Prix on Friday.
Williams has traditionally struggled in wet conditions since the start of the V6 era but has typically been strong at the Red Bull Ring, finishing on the podium in both 2014 and 2015.
Heavy rain fell during the second practice and both Bottas and Massa were able to pilot the FW38 in the tricky conditions, winding up ninth and 12th respectively.
"I think it was a good idea to go out in the rain to check the balance, because there’s a possibility of rain for the rest of the weekend," explained Bottas.
"We now have a good idea of how the car works in wet conditions and we will know what adjustments we need to make if it does rain."
Massa labelled his day as "reasonable" at the circuit where he claimed his most recent pole position in 2014.
"We couldn’t learn everything we would have liked because of the weather," he said.
"But the feeling of the car was okay in the wet, with half the track very wet and the other half quite dry, so it was actually a reasonable Friday to understand the car."
