Haas team principal Guenther Steiner confirmed one of his team’s chassis is heavier than the others, but stated it has not been used exclusively by Nikita Mazepin.Mick Schumacher, which he believes accounted for some of the difference in their results so far this season.
Steiner confirmed there is a discrepancy between the weight of the team’s cars. “One of the chassis is a little bit heavier,” he said. “But not in all circumstances, just when we need a certain weight balance so it ends up a little bit heavier. It’s marginal, but it is heavier.”
The difference is sufficient to create a difference in performance, Steiner confirmed. “Absolutely, it always has an impact. Heavier cannot have no impact, it’s physics.”
However Mazepin has not been alone in driving the heavier car. “We swapped the chassis around quite a bit and we always did,” said Steiner. “I don’t exactly know who has driven which chassis when and where but I think both drivers have driven all of our chassis.”
There are two reasons for the weight difference between the cars, Steiner explained. One was slightly heavier when the chassis was originally built last year, although it was within the team’s accepted tolerances. Repair work since then has added further weight.
“We carried all the chassis over from last year, just to clarify that,” said Steiner. “Like a lot of other teams did – because of the freezing of the car, the car is not a complete new build.”
“Part of it is in the tolerance when you build a car,” he explained. “And for sure over a year you do some repair jobs and maybe it got a little bit heavier there.
Mazepin is likely to continue using his current chassis for two more races after this weekend’s Austrian Grand Prix. “The plan is to have a new chassis for Belgium for him,” said Steiner.
