Formula 1 expert and former Grand Prix driver Marc Surer thinks Ferrari could be set to take on Mercedes AMG this weekend in Canada.
Reports this week suggested an engine performance upgrade for the Italian team could move it within 15 horse power of dominant Mercedes.
And Speed Week separately reports that Ferrari's works oil partner Shell has developed a new fuel that will also be debuted on the long straights of the Circuit Gilles Villeneuve.
"We do not stand still," team boss Maurizio Arrivabene is quoted by SID news agency. "We have a few things in the pipeline."
Surer, who works for the German broadcaster Sky, thinks Canada could be a good venue for Ferrari.
"There are a lot of straights," he said, "where the Ferrari is actually even slightly faster than the Mercedes.
"And the use of the softest tyre compounds also plays into their hands," added Surer. "But this track also gives an advantage to the drivers who brake latest, like (Lewis) Hamilton," Surer explained.
