Pastor Maldonado believes the results he has scored in the first half of the season have not matched the effort he has put in.
Maldonado has scored 12 points this year but also suffered six retirements as Lotus' season has failed to kick into gear in the opening nine rounds. But Maldonado is confident his luck will turn and more points will come in the second half of the year.
"I think my first half report card would say good things for effort, but the results didn't come," he said. "Certainly I believe we'll get better finishes in the second half of the season."
At Silverstone two weeks ago Maldonado was taken out in a chain reaction when Daniel Ricciardo hit his team-mate Romain Grosjean.
"My car was hit by Romain's as he had been tipped into a spin by Daniel Riccardo. I actually thought my car was okay except for a puncture so I tried to get back to the pits to change tyres. Unfortunately, what I could feel from the back of my car was not a puncture, it was oil leaking and making the tyre lose traction. As soon as Mark, my engineer, come over the radio to tell me to switch the car off I knew it was game over."
Maldonado is looking forward to a better result at the next round in Hungary.
"It is a very demanding circuit for drivers as it is often very hot and there are limited overtaking opportunities. It has quite a slow speed layout and we've looked quite good with the E23 in low speed corners so it will be interesting to see how quick we are here. Qualifying is so important at this track because of the small number of overtaking opportunities, but I've qualified well there in the past so hopefully I can deliver a strong performance."
