Lotus F1 Team deputy principal Federico Gastaldi says he is not happy with the results recorded in the 2015 season despite a respectable sixth place finish.
“The truth is that we were focused on achieving fifth place. That was our target since the beginning of the year, being realistic,” he told Motorsport.com.
“Being daring, we thought, if everything went well, that we could even fight for fourth place.
“But obviously things didn't turn out as we planned. The sixth place wasn't the target, and we're not pleased with that result. Not at all.”
Fifth-placed team Force India finished 58 points clear of Lotus, but Gastaldi’s insists the failure to achieve their desired goals is down to bad luck
“We had our problems, we had bad luck in the beginning of the season, many incidents that, if you look carefully, you'll see that weren't our drivers' fault,” he said.
“We know we have a very good team of people with experience in Enstone, and we know we can build good cars.
“Obviously we can't compete because we don't have the budget of Mercedes, Ferrari or Red Bull, but we thought we could fight for fourth or fifth position.”
Lotus F1 Team will not return to the grid next season, after it was taken over by Renault. The full details of the deal are yet to be closed.
