Nikita Mazepin received from Haas what he asked for, namely a lighter chassis and the Russian driver claims the change has “massively” impacted his one-lap pace.
Back in June, Mazepin justified his performance deficit to teammate Mick Schumacher by a heavier chassis that was leaving him a “sitting duck”.
At the time, Haas team boss Guenther Steiner confirmed that there was a weight difference between the two drivers’ chassis, but the Italian insisted the disparity was minimal.
Mazepin was nevertheless supplied with a new car at Spa and insists the change has been beneficial.
“I think our one-lap pace has massively improved ever since I drive from FP1 in Belgium,” said the Russian rookie.
“I think we all know what was the change in FP1 in Belgium, so it’s good to know that I can trust my feelings.
“The good thing is that the pace is here now, and we have a long season ahead of us.
“So I’m sure that it’s only going to get better, because the confidence that I have lost in the beginning of the year, when the car wasn’t doing what it was supposed to do, now it’s coming to the truth.”
