Pascal Wehrlein says there is a lot more to come from Manor in 2016, ahead of the third round of the F1 season in China.
The German driver impressed at the last race weekend in Bahrain, qualifying ahead of the Saubers and Renaults in 16th and finishing 13th.
“From start to finish it was a really positive race for me; so much better than Melbourne,” he said on the last race. “We qualified well, which helped, but to be mixing it with some of the bigger boys – beating them even – was really exciting.
“We’ve only just begun to extract some of the potential from the car so it was a good sign that there’s even more to come.”
He added: “The car was really quick on the straights and there are a couple of good ones here at Shanghai. What we know from Bahrain though is that there’s some more work to do to get the best from the car throughout the lap.
“There is still a lot we can do to continue improving the set-up and here we need a good compromise from straights to turns. It’s quite a challenging track so I’m looking forward to getting started.”
