That didn’t stop competitors from putting on a show amid the most trying of circumstances, and Stewart believes the ordeals brought his team closer together.
"It was an important time for us. It could have made us or broken us," Stewart told Supercars.com.
"It brought us tighter together and eliminated cliques and groups, and bonded us as a solid, strong team. It removed a lot of the bulls**t.
"We really grew through that period, but it was hard. It was bloody hard. Especially on the families, who were all in lockdown in Melbourne. So coming back and giving people a fair bit of time off after Bathurst was important.
"But when you try and understand where that’s taking you, and you look at the workshop in the first week of January, when it’s not mandatory to be back and you’ve got 90 per cent of your crew on deck at 100 per cent throttle, you go, 'Wow, this is a good environment to be part of'.
"I’m so thankful to have a good team around us."
From quarantining to mask-wearing, from paddock restrictions to a fan shut-out, events in 2020 threw several difficult challenges the way of teams, officials and broadcasters.
Stewart admitted the strains of 2020 were evident on team members’ mental health. However, he was grateful his squad was able to band together and emerge stronger.
"There are always hard moments when you have long periods away like that," he said.
"I think what was really good to notice was that everyone gave each other space, and we collectively understood that not everyone could be 'up' all the time.
"You got around the people who were feeling a little bit low, or feeling the pressures at home, or struggling a bit.
"We’d pull them back into a positive frame of mind in a positive way, which was cool. The team really gelled and we became a much better team for it."
