"In general it was a good weekend for us. The car was not so bad," said Sutil.
"We expected the worst as the pace wasn't there in Barcelona during testing. But here it was much better in qualifying, and in the race both cars finished, so it was a good result in the end," he added.
The fact that the drivers now know that there is a strong update package in the pipeline, Sutil said he was hoping to have an interesting race in Malaysia.
"It will be quite an interesting race.
"Let's see if the rain comes down. I hope so, as it will help us quite a lot!" said Sutil.
