Gene Haas says that "little things" are costing his Haas team performance as it bids to move up the Formula 1 grid this season.
Haas joined the sport in 2016 and made an immediate impact, with Romain Grosjean scoring 18 points from the opening two events, though added only another 11 across the remaining rounds of the season, as Haas placed eighth overall.
Haas again occupies eighth position in this year's standings, and the American owner reckons the squad's relatively young nature is still holding it back at times.
"I really didn’t know the depth of the technical challenges in Formula One and probably like most of the fans, they really don’t know how complex these cars are but it’s intriguing, it’s fun to get involved in it," he said.
"We have great partners and I think we’re doing OK. We were a little bit lucky last year and now our luck has got more normal, it’s more normal luck that you typically have in racing so it’s a challenge.
"It’s very hard competing against some of these… all these teams, they’re all very good at what they do.
"We’re weak in areas like tyre strategy and we’re a little weak in our pit areas. We get caught behind cars that cost us positions.
"All these ten little things that all add up to a tenth of a second. That’s really where we lose a lot of time and I think that as we develop, we get better at that."
