Pastor Maldonado said he was shocked by the stewards decision to hit him with a drive-through penalty for his controversial overtaking move on Paul Di Resta during Sunday's Hungarian Grand Prix.
The Williams driver, who has been heavily criticized by rival drivers for his over-aggressive driving, knocked his car into the side of the Briton's Force India as the pair were battling for position, forcing Di Resta on to the run-off area while the Venezuelan moved up a place.
Although Maldonado has picked up a string of penalties in recent races, he insisted he had done nothing wrong and questioned the stewards' decision.
"I have no idea why I got the penalty this time," he said. "It was a good overtaking manoeuvre.
"There was a small contact, but this is racing. I saw (Kimi) Raikkonen and (Romain) Grosjean (battling) and it was more or less the same."
The 27-year-old added that there was barely any contact between the two cars and insisted he felt the move was fair.
"The contact was so small," he said. "He decided to run wide because there was a lot of space off the track.
"There was nothing big from my point of view. It was a good move."
Maldonado eventually finished 13th and suggested the penalty had cost him a points finish.
"It cost the possibility of a point, we don't know, but my pace was good.
"I had a hard race, especially because of the start. We had the pace to fight for P10 as I was quicker than the Force Indias and even (Nico) Rosberg. But with the penalty, the chance was gone."
