For di Resta, the podium finish was a first step towards achieving the start-up Peugeot Sport outfit's goals of challenging WEC mainstay Toyota for victories.
The Scot stressed that "you cannot underestimate what they’ve been up against because it’s been new from a standstill" but has confidence that Peugeot is on a path of improvement.
"Rome was not built in a day, as you would say," he said.
"And I can’t specify enough just how much of a challenge it is to come into this championship now with the manufacturers and the people behind it. But we’ve moved on and we’re going forwards."
When asked by Autosport if Peugeot deserved more respect for its efforts, di Resta replied: "I guess the way you look at it is like baking a cake in a sense.
"The ingredients are right, it’s whether you’ve got the activation right. And you’ll only know at the end if the activation is right.
