The next two rounds on the calendar, in Spain and Monaco, feature very different characteristics and are unlike any tracks F1 has visited so far this year.
But, they share one common trait: they are tough to overtake on. This makes qualifying even more crucial, with track position holding that much more importance.
"After an exciting start to 2018 we're now heading into the European season with races like Spain and Monaco that present very different challenges than some of the previous tracks," said Toto.
"Overtaking is difficult in Barcelona and even more so in Monte Carlo, making track position key for a good race result.
"So, every team will work hard to get every last bit of performance out of the car in qualifying."
