Andretti saw James Courtney open his account with second and sixth and Scott Pye a pair of top 10s, as the outfit left atop the Teams’ Championship.
In 2017, Courtney took third and fourth in Adelaide, his best race results of the season and two of only five top 10s.
Walkinshaw acknowledged that his teams’ competitiveness was “a good step in the right direction” but also that its Commodores are traditionally strong in Adelaide.
Having been “high-fiving each other just getting one car in 10th at some events” last year, Walkinshaw says he wants consistent performances.
“Over the last few years in this team, some racetracks we’ve been incredibly fast, and some racetracks we’ve been nowhere,” Walkinshaw said. “Consistency has been lacking.
“One of the first steps is ‘let’s just get some consistency’, even if we’re consistently fifth, let’s get consistency in that place and that gives us a platform to build on.
“I think that’s what I would personally like to start seeing, just getting to every event we’re in the fight and we start building it up over time.
“And then you get to a position where the guys have got the confidence, it becomes a snowball.
“Their heads are up a lot more, they don’t second-guess each other, they’re confident in their decisions, there’s no ‘could I have done this? Could I have done that?’
“People understand what’s going on and that catalyses the team to become a more successful, cohesive unit.”
After its lengthy stint as Holden’s factory Supercars team concluded at the end of 2016, the outfit had further change last season with the exits of team principal Adrian Burgess and designer Alex Somerset in May and October.
