Kevin Magnussen was encouraged by the performance of the VF17 in Australia, despite the American team finishing with a double DNF.
Haas team principal, Guenther Steiner, recently claimed that the Ferrari engine powering the VF17 is on a par with Mercedes, perhaps even better.
Magnussen also shares the confidence in the car, and its pace was really encouraging to see.
"I’d rather have to sort out reliability than sort out an underperforming car. Performance-wise, it’s there. We just need to make it run," Magnussen said.
"It’s still very encouraging when you see the car is fast.
"It’s really good news that the car is as competitive as we had hoped for."
However, Magnussen was also keen to stress that the team cannot afford to be complacent after one race and the hard work must continue.
"There’s obviously no guarantee it’s going to be as competitive again," he warned.
"We need to work hard to get the most out of it and make it competitive again in China. The car was there, it was performing.
"It was just on my side I had a bit of a tough weekend. I didn’t get enough track time and there were too many issues with reliability that meant I didn’t have a good weekend. It’s positive, though."
