Rio Haryanto F1 2016 Test

Rio Haryanto says he was "finding the limits" of the Manor before crashing out of the final day of the first pre-season test at Barcelona.

Haryanto, who also spun out on Wednesday, slid rearwards into the wall at Turn 4 during the afternoon session, bringing out the red flags.

Damage to the rear of the car meant that the Indonesian was unable to make it back out on track during the remaining two and a half hours.

"I was getting used to the car and finding the limits, so I went a little bit too hot into Turn 4," said Haryanto, who ended up 11th overall.

"Unfortunately there was damage to the car, so we couldn't finish the afternoon session.

"It was a good morning session, where we were able to follow our run plan, and we did a lot of improvements. Hopefully I can still learn more at the next test."

Haryanto says he is gradually growing in confidence in his new surroundings.

"I'm getting more confident with the team, day-by-day," he said.
