Team-mate Lance Stroll could not run at all on Saturday at Albert Park because of engine problems and will start last.
Alonso said: “The mechanics, they’ve been working flat out and changing power-units day and night, you know, the last six weeks. So, even on the other side of the garage, with Lance being so unlucky in FP3 and ‘quali’ with zero laps, when you go on track and you are in the mix with a few cars, it’s a little bit better than being dead last, as we were yesterday.
“Maybe that’s enough to ignite a little bit of motivation in everyone in the garage. That’s probably part of our job now as drivers, you know, to keep the morale of the team high in difficult moments.”
The team are still facing a difficult situation and may not finish Sunday’s race.
They have only two batteries left for their hybrid system, and none available at the Honda factory, so will have to run a cautious race to ensure they are even able to take part in the second grand prix of the season, in China next weekend.
“We are short on parts, there is no secrets on that,” Alonso said.
“China is next week, so hopefully we can do as many laps as possible, hopefully we can do nearly the whole race.
“But the first sign that there is something potentially wrong, we cannot risk running, running, running until we make some big damage and then we compromise next week, so we will have to be very flexible.
“We are one team, we cannot separate the two things. There is no secret that the main problem is the PU. We are down power and reliability. We didn’t manage many laps in the winter and now we are short on stock for the batteries, we cannot do many laps or we are short on parts. We need to fix the power-units and Aston Martin is trying to help as much as possible with Honda.”
