It is. They are very slow comparatively through the corners though.
I thought Red Bull proved a few years back that being faster in the corners gets you more time on more tracks than being fast on the straights. For a couple of years a while back Williams had a very fast, slippery car that followed the "build the fastest car in a straight line" philosophy, and the best they could do was fourth in the WCC.
Ferrari may have built a fast engine, but if the car can't go round the bends as fast at it need to, if the drivers can't be fast enough (Vettel effectively slowing down the team, politics screwing Leclerc again), if the team isn't operating at one hundred percent in every aspect, then Mercedes are going to outperform you, because they are already at maximum everything right from the start of the season.
It's ominous, because we know Mercedes don't have the fastest car, we know they only get better as the year goes on, and they've already started the season at one hundred percent effort. At other times in the past, the speed of the Ferrari would have been enough to hide their other issues, but unluckily for Ferrari, they are up against today's Mercedes, who seems to be able to do everything right, make a minimum of mistakes, and get the race wins time and time again.
