Haas boss Guenther Steiner says the team does not yet understand why its performance disappeared at Formula 1’s Spanish Grand Prix, after initial promise.
Romain Grosjean classified comfortably within the top 10 during both practice sessions on Friday while Kevin Magnussen pinned his low-key placement on a scruffy lap on Soft tyres.
But on Saturday Haas regressed and suffered a double Q1 elimination, setting the tone for a race in which Magnussen registered 15th and Grosjean 19th.
Haas remains ninth in the Constructors’ Championship with just a solitary point to its name.
“We know haven’t got the best car and having the best car one day and the worst car another day I think we need to take it with a little bit of a pinch of salt,” he said.
“We need to look at why we lost so much performance from Friday to Sunday. The lap times on Friday were genuine and [in the race] we could only lap two seconds slower than Friday, so that is very strange.
“We need to go through aero data and then see if we can find something or what it could be.
“I’m not jumping to conclusions about the best, the worst, the medium and so on.
“We need to do some work for sure, we know we haven’t got the best car, but we just need to try to understand why there was this big difference between Friday and Sunday.”
