Bruno Senna believes he did all the Honda Racing team expected from him during his first test at the wheel of a Formula One car.
The Brazilian tested for the team at Barcelona on Monday and Wednesday, as Honda evaluate drivers to partner Jenson Button next season.
Senna covered 107 laps yesterday and posted the ninth quickest time of the day, just three tenths slower than Button himself.
The GP2 runner-up admitted he was pleased with his job.
"Last time I had driven a single-seater or any race car was two months ago in the last GP2 race, so for sure it has been a long time," Senna told reporters after the test.
"So every time you spend such a long time outside the side the muscles get used to other things, so I have been preparing and training as hard as I could. I tried to learn as much as I could. And I think considering my preparation I did a pretty good job.
"Driving a Formula One car is really, really nice. And I was enjoying myself more and more each lap. Pushing harder and harder makes you find the edge and when the laptime comes from your effort that's pretty good."
He added: "I'm happy. As I said, there was not a lot of pressure on me being matching Jenson or being super close to Jenson. They wanted to see what kind of information I could provide and if I was consistent and if I was quick on my own.
"I think I ticked all those boxes. I have to see how highly I have ticked those boxes but that's all I could do in my first day."
The Brazilian said he did not know yet if he would be called to test again next month.
"I would love to go to the Jerez test, but that depends on the team," he said.
