Hadjar's FP2 race simulation wasn't that bad, actually. It was close to the Ferraris. He had issues with the deployment consistency. There's a lot of software behind how the car knows which part of the track it's on. It sounds like they didn't get it right.
"Reliability has been good, but in terms of consistency, every lap in FP2 has been quite difficult, in terms of deployment and everything," Hadjar told the media in Melbourne. "But we'll look into it. It cannot go smooth on day one, so it's normal."
When asked if the inconsistency was due to difficulty harvesting energy around the Albert Park circuit, Hadjar added: "We are [having to try different things], and it's also constantly having to adapt your braking points, because you're never arriving at the same speed. The dynamic of the car changes as well, so it's very tricky."
