Ferrari endured a muted season-opening race because its pace-setting preseason testing form interpreted in to fifth and fourth on the road in Melbourne.
The Italian team states it’s made”adjustments” to exactly what it feels led to its feeble performance in Australia, and Marko thinks it’s engine-related.
Marko told Motorsport.com:”It’s quite obvious that Ferrari has under performed. Along with Haas.
“We don’t know exactly, but I think they merely cut back on performance because they had cooling issues.
“The Haas was unexpectedly slower compared [into the remainder of the field compared to its long-run pace in preseason testing].”
Sebastian Vettel faded dramatically through the Australian GP and Marko considers his lack of performance on fresher or softer tyres also pointed into a set-up related issue.
“This usually means that something was wrong. Vettel simply drove three halfway fast laps and then his speed fell.
“Ferrari was no danger on the yellowish tyre due to this fever and their noodle degradation.
“We however did not need some problems with degradation and were perhaps not really on the limit.”
Ferrari has adopted a different front-wing philosophy to Mercedes and RedBull this past year.
However, Marko disregarded the belief that this could have changed the way the Ferrari reacted into the bumpy Melbourne circuit compared to its competitors.
“The leading wing more or less determines the idea of the car.
“But there are lots of other things in front room that are likely involved as well.
“There are different theories, in terms of race speed just [race winner Valtteri] Bottas has been a step above the rest.
“Ferrari and [RedBull ] were on precisely the identical level.”
Ferrari has been Mercedes’ most persistent challenger in 2017 and 2018, and came under scrutiny last year due to its engine performance earnings.
Marko explained that another component in Ferrari’s performance was an apparent loss in a previous straightline rate advantage.
“The FIA reacted very well and closed several loopholes, or at least minimised them,” he explained.
“This usually means that these rate peaks, that Ferrari had on the last 25 percent or 30% of those straights, no longer exist. That is good.”
