Williams now face a weekend of playing catch up after both Rubens Barrichello and Pastor Maldonado saw their practice cut short in Japan today due to a number of issues.
Barrichello's FP1 session was hampered due to a puncture, resulting in the veteran ending up 17th.
His afternoon session also ended abruptly, but this time after he dropped a wheel on the grass entering the infamous first Degner, spitting his Williams into the tyre wall, leaving him 18th.
“I had limited running today which was unfortunate. In this morning's session, a puncture cut my session short and then an off this afternoon also put me out early,” lamented the Brazilian.
“The car felt quite loose before the incident and so we have a lot of things to look into now.”
Maldonado also lost time in FP2 and an engine problem limited him to just 16 tours - something the Venezuelan could have done without, especially with this being his first visit to Suzuka.
“An engine problem caused me to stop early in P2,” he confirmed. “It's my first time at Suzuka so I really need some more laps. We'll have our work cut out in tomorrow's final session.”
The team will now run a revised programme for tomorrow's third and final practice before qualifying.
“We've had a difficult start to the weekend with not as much running as we had hoped for. Accordingly, we have now revised the running plan going into P3. We did improve the set-up between sessions one and two though with some aero development and mechanical adjustments on the cars,” summarised Williams chief operations engineer, Mark Gillan.
